Introduction: Pulmonary sequestration is a rarely reported phenomenon where aberrant lung tissue exists independently from the rest of the tracheobronchial network. Complications may include hemothorax; however, there is a paucity of descriptions of this condition in the literature.Case Report: We describe a case of a pulmonary intralobar sequestration resulting in atraumatic tension hemothorax. A 73-year-old woman presented to our facility in extremis and with complaints of acute-onset flank pain. Her evaluation was notable for a large pulmonary sequestration with a presumed, moderate-sized effusion; however, initial review did not reveal an obvious underlying cause for her symptoms. Shortly after her arrival to the emergency department (ED) she experienced a cardiac arrest. On secondary review of her computed tomographic angiography, it was determined that what was previously thought to be a pleural effusion was a large hemothorax. Following this finding, a finger thoracostomy was performed, which resulted in the immediate evacuation of hemothorax. The thoracostomy was then converted into an ED thoracotomy to assess for active hemorrhage with brief return of spontaneous circulation. Prior to proceeding with emergent operative intervention, the patient’s spouse requested that all further resuscitative efforts cease, and the patient was allowed to expire. In a review of the case, it was determined that the patient suffered from cardiac arrest due to a spontaneous hemothorax secondary to a large intralobar pulmonary sequestration.Conclusion: Pulmonary intralobar sequestration can result in spontaneous hemorrhage with fatal results. Early and correct interpretation of imaging and surgical intervention are crucial in ED management.

Background: Trauma is a disease where time is of the essence. In many lower middle-income countries, definitive management and planning for trauma patients are often delayed after working hours because of either a lack of technicians to perform computed tomography (CT) scans or a lack of radiologists to interpret them. These lacunae can be bridged if more and more surgeons become confident in interpreting trauma CT images. Method: In this narrative review, written in a 'how to do it' manner, we describe a way of doing a structured and quick 'radiological primary survey' of the torso CT, which we believe will help quickly identify major injuries systematically, thereby avoiding delays in management and forming a care plan. The method has been developed by a team of trauma surgeons and radiologists and stems from the DRS ABCDE technique used in interpreting trauma chest X-rays. Result: The DRS ABCDE extrapolated to the trauma torso CT includes the following steps- Details, WRAP (W-windowing, R-Region, A-Axis, P-Phase), S- the Scout film, Airway, Breathing, Circulation, Disability and Extras. Conclusion: The review will enable resident trainees and trauma care professionals to interpret trauma CTs using a structured approach. [ABSTRACT FROM AUTHOR]

Zanubrutinib is an orally administered second-generation covalent inhibitor of Bruton tyrosine kinase that was recently approved by the US Food and Drug Administration for the treatment of chronic lymphocytic leukemia and small lymphocytic leukemia. It has been associated with significant major and minor bleeding events, including intracranial and GI hemorrhage and hematuria, with or without concurrent antiplatelet or anticoagulation therapy. We report a case of a 65-year-old man with relapsing chronic lymphocytic leukemia. He presented to us with repeated episodes of worsening dyspnea secondary to hemorrhagic pleural effusion 2 months after the initiation of zanubrutinib with concomitant apixaban use. On discontinuation of zanubrutinib after the second episode, he remained asymptomatic on further follow-up examination. Previously only described with the first-generation Bruton tyrosine kinase inhibitor, our case focuses attention on a rare adverse event and a first reported incidence, to our knowledge, of recurrent hemorrhagic pleural effusion associated with zanubrutinib in a patient with relapsing chronic lymphocytic leukemia.

Objective: Unusual clinical course Background: Coagulopathy caused by trauma itself is defined as trauma-induced coagulopathy (TIC). The pathophysiology of TIC is considered to consist of coagulation activation, hyperfibrinolysis, and consumption coagulopathy, similar to disseminated intravascular coagulation (DIC). This report describes a 48-year-old man with a history of epilepsy presenting with TIC associated with multiple traumatic fractures and hemothorax. Case Report: A 48-year-old man with a history of epilepsy fell while working on a second-floor roof and had right rib fractures (6th to 12th rib), right hemothorax, right clavicle fracture, right elbow fracture, and pelvic fractures. The right hemothorax became exacerbated and he went into shock. We performed the emergency surgery 5 hours after the trauma. Although circulation dynamics became stable and the discharge of chest drainage became thinned at postoperative day (POD) 1 while administering blood transfusions and tranexamic acid, hemoglobin remained below 8 g/dl, platelet count was below 60 000/µl, and prothrombin time - international normalized ratio (1.22) remained prolonged. Furthermore, the right hemothorax became exacerbated and re-operation was performed on the evening of POD2. Oozing hemorrhages from multiple rib fractures were observed. Although hemostatic management was performed with electrocautery and ultrasound energy devices, the hemorrhage could not be completely managed, so hemostasis was secured using hemostatic materials. Conclusions: The pathophysiologic mechanism of TIC has been emphasized as being different from that of DIC, and management of severe traumatic patients with TIC should be based on an understanding of the pathophysiology of TIC.

The precise assessment of hemothorax risk resulting from a rib fracture is not feasible. CT images, patient characteristics, and clinical experience are utilized in daily practice to assess risk intuitively. This study aimed to identify specific markers on CT images that can predict the risk of hemothorax. The study was retrospectively conducted between May 2021 and December 2023 at three different centers. Patients diagnosed with hemothorax at the initial assessment or during follow-up were identified among those being followed for rib fractures. An investigation was carried out to examine the relationship between the number of rib fractures, displacement status, and the location of the fracture on the rib arch with the risk of hemothorax. Of the 273 patients included in the study, 201 (73.6%) were male. The mean age was 53.9 ± 17.27 (19–93) years. Lateral (p = 0.029) and posterior (p < 0.001) location of the fracture and displacement of at least one fracture (p = 0.003) were associated with an increased risk. There was a significant correlation between the number of rib fractures and the risk of hemothorax (p < 0.001). The optimal cut-off for the number of rib fractures associated with a high risk of hemothorax was determined to be 4. Anatomical characteristics of a rib fracture can be useful to assess the risk of hemothorax practically in patients with thoracic trauma especially in emergency rooms. Patients with four or more rib fractures, at least one displaced rib fracture, and lateral and posterior rib fractures should be followed more carefully for hemothorax. [ABSTRACT FROM AUTHOR]

Background/Objectives: Endometriosis is characterized by the presence of ectopic endometrial-like glands and stroma outside the endometrial cavity, which mainly occurs in the pelvic cavity. Pulmonary endometriosis, or thoracic endometriosis syndrome (TES), describes the rare presence of endometrial-like cells in the thoracic cavity and includes catamenial pneumothorax, catamenial hemothorax, hemoptysis, and lung nodules. Our aim is to summarize the results of all reported cases of TES. Methods: Extensive research was conducted through MEDLINE/PUBMED using the keywords "thoracic endometriosis", "thoracic endometriosis syndrome", "catamenial pneumothorax", "catamenial hemoptysis", and "TES". Following PRISMA guidelines, all published cases of TES between January 1950 and March 2024 were included. A systematic review of 202 studies in English, including 592 patients, was performed. Results: The median age of women with TES is 33.8 years old. The most common clinical presentation is catamenial pneumothorax (68.4%), while lesions are mainly found in the right lung unilaterally (79.9%). Chest computed tomography (CT) was used alone or after an X-ray to determine the pathological findings. Ground-glass opacity nodules and cystic lesions represent the most common finding in CT, while pneumothorax is the most common finding in X-rays. Video-assisted thoracoscopic surgery (VATS) is the main therapeutic approach, usually in combination with hormonal therapy, including GnRH analogues, progestins, androgens, or combined oral contraceptives. Hormonal therapy was also administered as monotherapy. Symptom recurrence was reported in 10.1% of all cases after the treatment. Conclusions: High clinical awareness and a multidisciplinary approach are necessary for the best clinical outcome for TES patients. More studies are required to extract safer conclusions.

ABSTRACT: Neuroblastoma (NB) tumor rupture, typically intra-abdominal, is a rare and life-threatening condition with a poor prognosis, often associated with large aggressive tumors. Intrathoracic ruptures, rarely reported, may result from thoracic NB or malignant invasion. We present the first case of spontaneous intrathoracic rupture in a 2-year-old boy with abdominal NB.

BACKGROUND: Traumatic hemothorax (HTX) is often managed with tube thoracostomy (TT); however, TT carries a high complication rate. In 2017, a guideline was implemented at our Level I trauma center to observe traumatic HTX 300 mL or less in patients who are hemodynamically stable. We hypothesized that this guideline would decrease TT placement without increasing observation failure rates. STUDY DESIGN: This was a single-center retrospective review of all adult patients admitted with an HTX on CT before (2015 to 2016) and after (2018 to 2019) the guideline implementation. Exclusion criteria were TT placement before CT scan, absence of CT scan, death within 5 days of admission, and a concurrent pneumothorax more than 20 mm. HTX volume was calculated using CT scan images and Mergo's formula: V = d2 x L (where V is the volume, d is the depth, and L is the length). The primary outcome was observation failure, defined as the need for TT, video-assisted thoracoscopic surgery, thoracotomy after repeat imaging or worsening of symptoms, and pulmonary morbidity. RESULTS: A total of 357 patients met inclusion criteria, of whom 210 were admitted after guideline implementation. No significant differences in baseline demographics, comorbidities, or injury characteristics across both cohorts were observed. The postimplementation cohort had a significant increase in observation rate (75% vs 59%) and a decrease in TT placement (42% vs 57%). The postimplementation group had a statistically significant shorter hospital (6 vs 8 days) and ICU (2 vs 3 days) length of stay. No significant differences in observation failure, pulmonary complications, 30-day readmission, or 30-day mortality were observed across both cohorts. CONCLUSIONS: The implementation of the 300-mL guideline led to a decrease in TT placement without increasing observation failure or complication rates. [ABSTRACT FROM AUTHOR]

Introduction and objectives: Osler Weber Rendu disease is a rare genetic disorder characterized by multiple telangiectasias and arteriovenous malformations involving parenchymatous organs, leading to hemorrhagic, sometimes life threatening vascular complications. The most often involved regions are the central nervous system and lungs, but the disease can also manifest at hepatic, intestinal, splenic or urinary level. The objective of this article is to raise the awareness over an extremely severe complication of Osler Weber Rendu and the importance of an early diagnosis. Materials and methods: We present the case of a 65 years old woman with Osler Weber Rendu with many complications, who was hospitalized and surgically treated for massive hemothorax and hemorrhagic shock by rupture of a pulmonary vascular malformation. The patient presented for latero-thoracic and anterior chest pain with a sudden onset in the last 24 hours, which was followed by progressive dyspnea, being further diagnosed with massive right hemothorax. Results: After the emergency surgical treatment which consisted of inferior bi-lobectomy, the evolution was a difficult one, the recovery of the patient being slowed down by her altered neurological status and the presence of a persistent bronchial stump fistula. Her disease was complicated by a post transfusion syndrome which aggravated the respiratory failure and necessitated the initiation of cortico-therapy and also by the colonization and subsequent infection of the respiratory tract with multi resistant microorganisms. The patient died on the 32nd postoperative day. Conclusions: Our patient had in her personal medical history few complications of Osler Weber Rendu disease, but these manifested as non-specific symptoms which were not further investigated in order to early establish the diagnosis of the disease. Therefore, the importance of the disease was overridden as time passed and the diagnosis was delayed, which prevented any therapeutic measures of the associated life-threatening complications, as is in this case the massive hemothorax.

Background: The majority of the patients with a solitary fibrous tumor (SFT) of the pleura are asymptomatic, and rupture of an SFT with hemothorax is rare. Case presentation: A 48-year-old man was taken by ambulance to our hospital because of sudden onset of left chest pain. Two months before the referral, a tumor was detected in the left upper lobe of the lung by screening computed tomography at another hospital, and further observation was recommended, because the tumor was suspected to be benign. Our contrast-enhanced computed tomography analysis of the chest revealed a solid tumor (5 cm in diameter) with an irregular enhancement effect close to the pericardium and pleural effusion in the left thoracic cavity. Pleural effusion was not detected in the previous imaging analysis. CT number of the pleural effusion was 40 HU, and the pleural effusion was suspected to be hematogenous. Therefore, rupture of the tumor with bleeding was suspected as the cause of the effusion because of the sudden onset. Preoperative diagnosis was a mediastinal tumor, such as a teratoma, because the tumor was close to the pericardium. Thoracoscopic surgery was performed with the patient in the right lateral decubitus position; bloody pleural effusion was observed and drained. The tumor originated from the visceral pleura of the left upper lobe of the lung and was resected with a surgical stapler. Macroscopic analyses of the resected tumor indicated that bleeding were caused by the rupture of the tumor at the defect of the capsule wall. The operation took 63 min. The postoperative pathological diagnosis was a benign SFT. Hemorrhage was observed just under the capsule wall of the tumor. The postoperative course of the patient was uneventful, and he was discharged 2 days after surgery. Conclusions: Even when an SFT is neither huge nor malignant, rupture can occur, and resection should be considered regardless of the size or malignant characteristics. After an SFT rupture, careful follow-up is needed to monitor for the intrathoracic recurrence or dissemination of the tumor. [ABSTRACT FROM AUTHOR]

Background: Thoracic trauma frequently includes a pneumothorax, hemothorax, or hemopneumothorax, which may necessitate an Intercostal drainage (ICD) for air and fluid evacuation to improve breathing and circulatory function. It is a simple and life-saving procedure; nevertheless, it carries morbidity, even after its removal. Efforts have been made continuously to shorten the duration of ICD, but mostly in non-trauma patients. In this study, we evaluated the impact of negative pleural suction over the duration of ICD. Methods: This study was a prospective randomized controlled interventional trial conducted at Level 1 Trauma Centre. Thoracic trauma patients with ICD, who met the inclusion criteria (sample size 70) were randomized into two groups, the first group with negative pleural suction up to -20 cm H2O, and the second group as conventional, i.e. ICD connected to underwater seal container only. The primary objective was to compare the duration of ICDs and the secondary objectives were the length of hospital stay and various complications of thoracic trauma. Results: Duration of ICD was measured in median days with minimum & maximum days. For the negative suction group, it was 4 days (2-16 days); for the conventional group, it was also 4 days (2-17 days). There was also no significant difference among both groups in length of hospital stay. Conclusion: The beneficial effect of negative pleural suction to ICD could not be demonstrated over the duration of ICD and hospital stay. In both groups, there was no significant difference in complication rates like recurrent pneumothorax, retained hemothorax, persistent air leak, and empyema. Level of evidence: Therapeutic Study, Level II Trial registration: This trial was registered with the Clinical Trial Registry of India (CTRI) with registration no. REF/2020/11/038403.

Background: Cardiopulmonary resuscitation (CPR) is performed in cardiac arrests. There exist life support guidelines for individuals in performing effective CPR. CPR-related bleeding and hemothoraces are rare. Intercostal artery rupture leading up to shock and respiratory compromise in such situations is rare. Here, we present a unique case with a management dilemma while discussing challenges and guidance to regional centers. Case presentation: A 49-year-old Caucasian male experienced an out-of-hospital cardiac arrest which required bystander cardiopulmonary resuscitation from a colleague prior to commencement of lysis protocol at the local hospital. Transfer was later arranged to the nearest cardiac catheterization laboratory where a rescue percutaneous coronary intervention was performed in the left anterior descending artery that required strict dual antiplatelet use. Beneath the shroud of these events was a life-threatening right-sided hemothorax from rupture of intercostal arteries that occurred during initial resuscitation. Astute recognition of this post-percutaneous coronary intervention resulted in eventual transfer of the patient to a tertiary center where the source and the collection of the bleed was addressed. The patient's took a great trajectory to improvement. Conclusions: A regional center poses many challenges and limitations. Massive bleeding from intercostal arteries leading to hemorrhagic shock and respiratory compromise from an expanding hemothorax post-CPR is rare. Post-percutaneous coronary intervention use of dual antiplatelets posed a management dilemma that prompted assistance from tertiary counterparts. Clinicians should be astute and quick in assessing and providing care. [ABSTRACT FROM AUTHOR]

Background: Video-assisted thoracoscopic surgery (VATS) is a practical resource in the management of traumatic hemothorax. However, it carries inherent risks and should be mobilized cost-effectively. In this study, we investigated the ideal VATS timing using cost analysis. Methods: 617 cases of unilateral traumatic hemothorax from 2012 to 2022 were identified in our trauma database. We extracted encounter cost, length of stay (LOS), and operative cost information. Using Kruskal-Walli's test, we compared the cost and LOS for patients who underwent VATS or continued nonoperative management in the first 7 days of admission. Additionally, we computed the daily proportion of patients initially managed nonoperatively but ultimately underwent VATS. P -values <.05 were considered significant. Results: The median encounter cost of cases managed operatively before hospital day 4 (HD4) was higher than those managed nonoperatively. This difference was $63k on HD2 (P -value.07) and was statistically significant for HD3 (difference of $65k, P -value.02). The median LOS with operational management on HD2 and 3 was 7 and 6 respectively vs median LOS of 2 and 3 with nonoperative management on those days (P -value <.001,.01 respectively). The proportion of patients who failed nonoperative management did not change from baseline until HD4 (23% (95% CI 19.7, 26.3) vs 33.9% (95% CI 28.3, 39.6), P -value <.001). Discussion: Early mobilization of VATS before hospital day 4 increases the overall hospital cost without offering any length of stay benefit. Continuing nonoperative management longer than 4 days is associated with a high failure rate and a costlier operation. [ABSTRACT FROM AUTHOR]

BACKGROUND: There is a need for activation criteria that reflect the different factors affecting rural trauma patients. OBJECTIVE: To develop effective activation criteria for a rural trauma center among adults, incorporating variables specific to the geography, mechanisms of injury, and population served. METHODS: This is a single-center, retrospective cohort study conducted from (23 years) January 1, 2000, to July 31, 2023. The data collected patient demographics, injury details, morbidity, and preexisting comorbidity. This research included all adult (≥15 years) true Level I trauma activations defined as an injury severity score > 25 and met the need for trauma intervention criteria. The patients were grouped into adult and elderly categories. The analysis utilized a logistic regression model with the outcome of a true Level I trauma activation. RESULTS: A total of 19,480 patients were included in the sample; 2,858 (14.6%) met the Level I activation criteria. Elderly Level I activation included assault, pedestrian struck, multiple pelvic fractures, traumatic pneumo/hemothorax, mediastinal fracture, sternum fracture, and flail rib fracture. CONCLUSION: Using the findings of the logistic regression model, this center has made more robust activation guidelines adapted to its rural population. [ABSTRACT FROM AUTHOR]

Background Trauma cases, particularly those resulting from high-speed accidents, are becoming increasingly prevalent and contribute significantly to morbidity and mortality rates. The thoracic cage, despite its robust structure, is susceptible to injuries that can lead to severe consequences. Chest injuries account for a substantial portion of trauma-related deaths, necessitating a comprehensive understanding of their scope and management. Methods This prospective study aims to investigate the clinico-pathological profile of patients with chest injuries due to blunt trauma, focusing on their demographic characteristics, etiology of trauma, clinical presentation, associated injuries, and management approaches. The study was conducted at a tertiary care center, and data were collected from 115 patients presenting to the Casualty department. Patients with chest trauma such as rib fractures or lung contusions, were admitted for observation and further management. Results Majority of the patients were males in the young and middle age groups. Road traffic accidents were the leading cause of chest trauma, followed by falls. Alcohol consumption was prevalent among male patients involved in road traffic accidents. The most common presenting complaint was pain, often accompanied by dyspnea. Rib fractures were present in a significant portion of patients, with some individuals having multiple fractured ribs. Pneumothorax, hemothorax, and combined injuries were also observed. In terms of management, a significant proportion of cases underwent tube thoracostomy, while a small number required thoracotomy. Mortality rates were low, and complications such as empyema were infrequent. Conclusion This study provides valuable insights into the clinico-pathological profile of patients with chest injuries. Understanding the demographics, etiology, clinical presentation, associated injuries, and management approaches can aid healthcare professionals in providing timely and appropriate care. Emphasizing the importance of early evaluation, appropriate imaging, and effective management strategies, such as tube thoracostomy, can help improve outcomes and reduce the burden on tertiary care centers.

Surgical evacuation has long been the standard treatment for hemothorax. However, some patients are not suitable candidates for surgery. Intrapleural fibrinolytic therapy (IPFT) has recently emerged as an effective alternative for managing retained hemothorax. This case report describes two patients with retained hemothorax who were unfit for surgery and were successfully treated with IPFT at our centre. Both patients were deemed unsuitable for surgery due to comorbidities and their overall functional status. They received three cycles of IPFT, each consisting of 2.5 mg of alteplase. This treatment effectively evacuated the retained hemothorax, achieving complete radiological resolution without immediate or delayed complications up to 3 months post‐discharge.

The landscape of cardiac pacemaker technology has undergone significant evolution over the last two decades, transitioning from simple single-chamber devices to sophisticated multi-chamber rate-responsive systems and cardioverter defibrillators. This progression has introduced a complex array of complications inherent to device implantation and operation, encompassing both mechanical and clinical challenges. These complications notably include lead dislodgment, device migration, venous thrombosis, and hemothorax, which not only affect patient outcomes but also impose substantial economic burdens. This review meticulously analyzes these complications, elucidating their mechanisms, clinical implications, and the economic consequences associated with their management. It also outlines current and emerging strategies aimed at mitigating these complications, emphasizing the need for continual updates in clinical practices and protocols. Through this discourse, the review seeks to equip clinicians with a comprehensive understanding of these complications, thereby enhancing the safety and efficacy of cardiac pacing interventions.

Inferior phrenic artery to pulmonary artery fistulae are a rare anomaly seen on CT thorax angiogram when evaluating for certain pulmonary pathological conditions. A 79-year-old man with hemothorax on chest X-ray was evaluated by interventional radiology for embolization of a bleeding vessel. During the procedure, a fistulous connection between the right inferior phrenic artery and right pulmonary artery with signs of extravasation was found and embolized, significantly reducing the size of the hemothorax. This case demonstrates that inferior phrenic artery to pulmonary artery fistulae, a rarely seen vascular anomaly, can result in life-threatening hemothorax.

Abstract Background Hemorrhage is the most common major complication after liver biopsy. Hemothorax is one type of bleeding and is very rare and dangerous. Several cases of hemothorax subsequent to liver biopsy have been documented, primarily attributed to injury of the intercostal artery or inferior phrenic artery and a few resulting from lung tissue damage; however, no previous case report of hemothorax caused by injury of musculophrenic artery after liver biopsy has been reported. Case presentation A 45-year-old native Chinese woman diagnosed with primary biliary cirrhosis due to long-term redness in urination and abnormal blood test indicators was admitted to our hospital for an ultrasound-guided liver biopsy to clarify pathological characteristics and disease staging. A total of 2 hours after surgery, the patient complained of discomfort in the right chest and abdomen. Ultrasound revealed an effusion in the right thorax and hemothorax was strongly suspected. The patient was immediately referred to the interventional department for digital subtraction angiography. Super-selective angiography of the right internal thoracic artery was performed which revealed significant contrast medium extravasation from the right musculophrenic artery, the terminal branch of the internal thoracic artery. Embolization was performed successfully. The vital signs of the patient were stabilized after the transarterial embolization and supportive treatment. Conclusion This case draws attention to the musculophrenic artery as a potential source of hemorrhage after percutaneous liver biopsy.

Abstract Background Late hemothorax is a rare complication of blunt chest trauma. The longest reported time interval between the traumatic event and the development of hemothorax is 44 days. Case presentation An elderly patient with right-sided rib fractures from chest trauma, managed initially with closed thoracostomy, presented with a delayed hemothorax that occurred 60 days after initial management, necessitating conservative and then surgical intervention due to the patient’s frail condition and associated complications. Conclusions This case emphasizes the clinical challenge and significance of delayed hemothorax in chest trauma, highlighting the need for vigilance and potential surgical correction in complex presentations, especially in the elderly.

Abstract Background Pulmonary arteriovenous malformation (PAVM), also known as pulmonary arteriovenous fistula, is a rare vascular developmental anomaly. Most cases of PAVM are associated with hereditary hemorrhagic telangiectasia (HHT). Hemothorax associated with PAVM is even rarer, and management concerning this complication still challenges. Case presentation A 55-year-old man with sudden onset of dyspnea and chest pain was admitted to our hospital. He had a medical history of epistaxis, intraperitoneal germ cell tumor and PAVM. Chest unenhanced CT revealed the left-sided pleural effusion together with partial passive atelectasis and gradual increase at the interval of six days. Diagnostic thoracocentesis further revealed hemorrhagic effusion. CT angiography (CTA) showed tortuously dilated lumen of the left lower pulmonary artery and PAVM with the formation of aneurysm. Due to his family's refusal of surgery, the patient underwent transcatheter embolization therapy. However, the left pleural effusion did not significantly reduce and there was a slow drop in hemoglobin value even after interventional treatment, indicating the possibility of ongoing active bleeding. Eventually, the patient received lobectomy of the left lower lobe with a satisfactory outcome. Conclusions Massive hemothorax resulting from PAVM rupture into the pleural space can lead to fatal outcomes. CTA can accurately diagnose this pathologic condition. Transcatheter embolization is frequently used in the treatment of PAVM, but it may be challenging to achieve the desirable effect in patients with hemothorax. Combined with our case and literature review, direct radical surgery can lead to a successful outcome when PAVM complicated with hemothorax and a large diameter of the draining vein.

Abstract The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64–14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826–0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma.

Background: Blunt traumatic aortic injury (BTAI) is the second leading cause of death due to traumas in young patients. The primary presentation might be chest or interscapular pain, difficulty in breathing, and, in severe cases, hypotension. Considering the rapid deterioration of these patients' clinical conditions, prompt diagnosis and treatment initiation are crucial. In these injuries, the most involved parts of the aorta are the isthmus (distal to the left subclavian artery) and the descending part in the thorax. Therefore, the main diagnostic strategies include transthoracic echocardiography, CT angiography, and endovascular diagnostic approaches. Case presentation The patient was a 19-year-old male presenting with the symptoms of chest pain, dyspnea, and extremities excruciating pain after a car turnover. The initial evaluation showed no abnormal cardiovascular finding except bilateral hemothorax, addressed with chest tubes. Twelve hours later, when the patient was under observation for orthopedic surgeries, his chest pain and dyspnea started, and TTE and CTA showed a grade three descending aneurysm of the aorta. The patient was treated immediately with an endovascular procedure of stent implantation. A delayed debranching surgery was also performed, which resulted in desirable outcomes and uneventful follow-up. Conclusion: Although open thoracic surgery is the main and almost the only option for treating aneurysms of the aorta in hemodynamically unstable patients, the endovascular procedure has shown superior outcomes in selected patients with appropriate anatomy. Debranching surgery, which can be done simultaneously or with delay after the initial procedure, has proven protective against thromboembolic cerebral events. Clinical key point: Patients with an aneurysm of the aorta should be transported to a medical center with a multidisciplinary team for an urgent evaluation and treatment. The initial resuscitation and diagnosis are challenging, considering the fatal nature of these injuries, and the selection of the treatment is based on the patient's clinical condition and evaluated anatomy in cardiovascular imaging.

Purpose: Post-operative pain after video-assisted thoracoscopic surgery is often treated using thoracic epidural analgesics or thoracic paravertebral analgesics. This article describes a case where a thoracic disc herniation is treated with a thoracoscopic microdiscectomy with post-operative thoracic epidural analgesics. The patient developed a bupivacaine pleural effusion which mimicked a hemothorax on computed tomography (CT). Methods: The presence of bupivacaine in the pleural effusion was confirmed using a high performance liquid chromatography method. Results: The patient underwent a re-exploration to relieve the pleural effusion. The patient showed a long-term recovery similar to what can be expected from an uncomplicated thoracoscopic microdiscectomy. Conclusion: A pleural effusion may occur when thoracic epidural analgesics are used in patents with a corridor between the pleural cavity and epidural space. [ABSTRACT FROM AUTHOR]

Background: Blunt thoracic trauma accounts for a majority of trauma-related admissions. The Eastern Association for the Surgery of Trauma guidelines recommend placement of a tube thoracostomy for all patients with a hemothorax. Our study was conducted to look at those managed without an intercostal drain (ICD) and the factors that could predict a failure in conservative management. Materials and Methods: A retrospective study was conducted from January 2020 to June 2022 at a level-one trauma center in South India to account for patients who required a tube thoracostomy after planned expectant management for hemothorax. All adult patients above 16 years, with traumatic hemothorax were included. Those who had ICD inserted in the emergency department before computed tomography (CT) and those who did not have a CT Thorax were excluded. A retrospective review of patient records was conducted and analyzed using Stata (ver. 16). Results: Eighty-eight patients were included in the study, of whom 11 patients required a tube thoracostomy after an initial trial of conservative/expectant management (i.e., not inserting an ICD). The most common reason for failure was an increase in the size of the hemothorax. Among all the predictors we looked at, only a systolic blood pressure of <90 mm Hg on presentation was statistically significant for predicting failure of expectant management. Conclusion: Our study suggests not all patients with a traumatic hemothorax require a tube thoracostomy and can be managed expectantly provided close monitoring is possible. An increase in the size of the hemothorax was the main indication for a tube thoracostomy. [ABSTRACT FROM AUTHOR]

Introduction and objectives: Osler Weber Rendu disease is a rare genetic disorder characterized by multiple telangiectasias and arteriovenous malformations involving parenchymatous organs, leading to hemorrhagic, sometimes life-threatening vascular complications. The most often involved regions are the central nervous system and lungs, but the disease can also manifest at hepatic, intestinal, splenic or urinary level. The objective of this article is to raise the awareness over an extremely severe complication of Osler Weber Rendu and the importance of an early diagnosis. Materials and methods: We present the case of a 65 years old woman with Osler Weber Rendu with many complications, who was hospitalized and surgically treated for massive hemothorax and hemorrhagic shock by rupture of a pulmonary vascular malformation. The patient presented for latero-thoracic and anterior chest pain with a sudden onset in the last 24 hours, which was followed by progressive dyspnea, being further diagnosed with massive right hemothorax. Results: After the emergency surgical treatment which consisted of inferior bi-lobectomy, the evolution was a difficult one, the recovery of the patient being slowed down by her altered neurological status and the presence of a persistent bronchial stump fistula. Her disease was complicated by a post transfusion syndrome which aggravated the respiratory failure and necessitated the initiation of cortico-therapy and also by the colonization and subsequent infection of the respiratory tract with multi resistant microorganisms. The patient died on the 32nd postoperative day. Conclusions: Our patient had in her personal medical history few complications of Osler Weber Rendu disease, but these manifested as non-specific symptoms which were not further investigated in order to early establish the diagnosis of the disease. Therefore, the importance of the disease was overridden as time passed and the diagnosis was delayed, which prevented any therapeutic measures of the associated life-threatening complications, as is in this case the massive hemothorax.

Screening for pneumothorax (PTX) is standard practice after thoracostomy tube removal, with postpull CXR being the gold standard. However, studies have shown that point-of-care thoracic ultrasound (POCTUS) is effective at detecting PTX and may represent a viable alternative. This study aims to evaluate the safety and efficacy of POCTUS for evaluation of clinically significant postpull PTX compared with chest x-ray (CXR). We performed a prospective, cohort study at a Level 1 trauma center between April and December 2022 comparing the ability of POCTUS to detect clinically significant postpull PTX compared with CXR. Patients with thoracostomy tube placed for PTX, hemothorax, or hemopneumothorax were included. Clinically insignificant PTX was defined as a small residual or apical PTX without associated respiratory symptoms or need for thoracostomy tube replacement while clinically significant PTX were moderate to large or associated with physiologic change. We included 82 patients, the most common etiology was blunt trauma (n = 57), and the indications for thoracostomy tube placement were: PTX (n = 38), hemothorax (n = 15), and hemopneumothorax (n = 14). One patient required thoracostomy tube replacement for recurrent PTX identified by both ultrasound and X-ray. Thoracic ultrasound had a sensitivity of 100%, specificity of 95%, positive predictive value of 60%, and negative predictive value of 100% for the detection of clinically significant postpull PTX. The use of POCTUS for the detection of clinically significant PTX after thoracostomy tube removal is a safe and effective alternative to standard CXR. This echoes similar studies and emphasizes the need for further investigation in a multicenter study. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this case report is to report that delayed hemothorax is possible after anterior vertebral body tethering (aVBT) and to illustrate the course of treatment. Methods: We present a 15-year-old boy with adolescent idiopathic scoliosis who underwent an anterior thoracoscopic assisted vertebral body tethering who developed a massive right-sided hemothorax 12 days post-operatively. A chest tube was placed to drain the hemothorax and later required embolectomy with tissue plasminogen activator (TPA) to drain the retained hemothorax. Results: At 1 month follow up post discharge the patient was asymptomatic, and radiograph did not demonstrate evidence of residual hemothorax and scoliosis. We have followed this patient for 5 years postoperative and he continues to do well clinically and radiographically. Conclusions: Pulmonary complications are a known drawback of anterior thoracoscopic spinal instrumentation. Delayed hemothorax is possible after aVBT. In the case of a retained hemothorax, chest tube treatment with TPA is a safe and effective method of embolectomy. [ABSTRACT FROM AUTHOR]

Background: Hemorrhage is the most common major complication after liver biopsy. Hemothorax is one type of bleeding and is very rare and dangerous. Several cases of hemothorax subsequent to liver biopsy have been documented, primarily attributed to injury of the intercostal artery or inferior phrenic artery and a few resulting from lung tissue damage; however, no previous case report of hemothorax caused by injury of musculophrenic artery after liver biopsy has been reported. Case presentation: A 45-year-old native Chinese woman diagnosed with primary biliary cirrhosis due to long-term redness in urination and abnormal blood test indicators was admitted to our hospital for an ultrasound-guided liver biopsy to clarify pathological characteristics and disease staging. A total of 2 hours after surgery, the patient complained of discomfort in the right chest and abdomen. Ultrasound revealed an effusion in the right thorax and hemothorax was strongly suspected. The patient was immediately referred to the interventional department for digital subtraction angiography. Super-selective angiography of the right internal thoracic artery was performed which revealed significant contrast medium extravasation from the right musculophrenic artery, the terminal branch of the internal thoracic artery. Embolization was performed successfully. The vital signs of the patient were stabilized after the transarterial embolization and supportive treatment. Conclusion: This case draws attention to the musculophrenic artery as a potential source of hemorrhage after percutaneous liver biopsy. [ABSTRACT FROM AUTHOR]

Background: Late hemothorax is a rare complication of blunt chest trauma. The longest reported time interval between the traumatic event and the development of hemothorax is 44 days. Case presentation: An elderly patient with right-sided rib fractures from chest trauma, managed initially with closed thoracostomy, presented with a delayed hemothorax that occurred 60 days after initial management, necessitating conservative and then surgical intervention due to the patient’s frail condition and associated complications. Conclusions: This case emphasizes the clinical challenge and significance of delayed hemothorax in chest trauma, highlighting the need for vigilance and potential surgical correction in complex presentations, especially in the elderly.

Background: Pulmonary arteriovenous malformation (PAVM), also known as pulmonary arteriovenous fistula, is a rare vascular developmental anomaly. Most cases of PAVM are associated with hereditary hemorrhagic telangiectasia (HHT). Hemothorax associated with PAVM is even rarer, and management concerning this complication still challenges. Case presentation: A 55-year-old man with sudden onset of dyspnea and chest pain was admitted to our hospital. He had a medical history of epistaxis, intraperitoneal germ cell tumor and PAVM. Chest unenhanced CT revealed the left-sided pleural effusion together with partial passive atelectasis and gradual increase at the interval of six days. Diagnostic thoracocentesis further revealed hemorrhagic effusion. CT angiography (CTA) showed tortuously dilated lumen of the left lower pulmonary artery and PAVM with the formation of aneurysm. Due to his family's refusal of surgery, the patient underwent transcatheter embolization therapy. However, the left pleural effusion did not significantly reduce and there was a slow drop in hemoglobin value even after interventional treatment, indicating the possibility of ongoing active bleeding. Eventually, the patient received lobectomy of the left lower lobe with a satisfactory outcome. Conclusions: Massive hemothorax resulting from PAVM rupture into the pleural space can lead to fatal outcomes. CTA can accurately diagnose this pathologic condition. Transcatheter embolization is frequently used in the treatment of PAVM, but it may be challenging to achieve the desirable effect in patients with hemothorax. Combined with our case and literature review, direct radical surgery can lead to a successful outcome when PAVM complicated with hemothorax and a large diameter of the draining vein.

Introduction: Military working dogs (MWDs) are essential for military operations in a wide range of missions. With this pivotal role, MWDs can become casualties requiring specialized veterinary care that may not always be available far forward on the battlefield. Some injuries such as pneumothorax, hemothorax, or abdominal hemorrhage can be diagnosed using point of care ultrasound (POCUS) such as the Global FAST® exam. This presents a unique opportunity for artificial intelligence (AI) to aid in the interpretation of ultrasound images. In this article, deep learning classification neural networks were developed for POCUS assessment in MWDs. Methods: Images were collected in five MWDs under general anesthesia or deep sedation for all scan points in the Global FAST® exam. For representative injuries, a cadaver model was used from which positive and negative injury images were captured. A total of 327 ultrasound clips were captured and split across scan points for training three different AI network architectures: MobileNetV2, DarkNet-19, and ShrapML. Gradient class activation mapping (GradCAM) overlays were generated for representative images to better explain AI predictions. Results: Performance of AI models reached over 82% accuracy for all scan points. The model with the highest performance was trained with the MobileNetV2 network for the cystocolic scan point achieving 99.8% accuracy. Across all trained networks the diaphragmatic hepatorenal scan point had the best overall performance. However, GradCAM overlays showed that the models with highest accuracy, like MobileNetV2, were not always identifying relevant features. Conversely, the GradCAM heatmaps for ShrapML show general agreement with regions most indicative of fluid accumulation. Discussion: Overall, the AI models developed can automate POCUS predictions in MWDs. Preliminarily, ShrapML had the strongest performance and prediction rate paired with accurately tracking fluid accumulation sites, making it the most suitable option for eventual real-time deployment with ultrasound systems. Further integration of this technology with imaging technologies will expand use of POCUS-based triage of MWDs. [ABSTRACT FROM AUTHOR]

The shock index (SI) has been associated with predicting transfusion needs in trauma patients. However, its utility in penetrating thoracic trauma (PTTrauma) for predicting the Critical Administration Threshold (CAT) has not been well-studied. This study aimed to evaluate the prognostic value of SI in predicting CAT in PTTrauma patients and compare its performance with the Assessment of Blood Consumption (ABC) and Revised Assessment of Bleeding and Transfusion (RABT) scores. We conducted a prognostic type 2, single-center retrospective observational cohort study on patients with PTTrauma and an Injury Severity Score (ISS) > 9. The primary exposure was SI at admission, and the primary outcome was CAT. Logistic regression and decision curve analysis were used to assess the predictive performance of SI and the PTTrauma score, a novel model incorporating clinical variables. Of the 620 participants, 53 (8.5%) had more than one CAT. An SI > 0.9 was associated with CAT (adjusted OR 4.89, 95% CI 1.64–14.60). The PTTrauma score outperformed SI, ABC, and RABT scores in predicting CAT (AUC 0.867, 95% CI 0.826–0.908). SI is a valuable predictor of CAT in PTTrauma patients. The novel PTTrauma score demonstrates superior performance compared to existing scores, highlighting the importance of developing targeted predictive models for specific injury patterns. These findings can guide clinical decision-making and resource allocation in the management of PTTrauma. [ABSTRACT FROM AUTHOR]

Recent evidence indicates that elderly who have suffered rib fractures may develop delayed massive hemothorax. Delayed enormous hemothorax after thoracic trauma is uncommon, but it is nevertheless linked to high rates of mortality. This single case report provides an overview of the ordinary and important delayed hemothorax caused by thoracic trauma with multiple rib fractures in limited healthcare facilities. We observe symptoms and chest X-rays before and after the development of delayed hemothorax. A 56-year-old man came to the hospital with complaints of shortness of breath and pain in the chest and right shoulder. The patient said that four days ago, He fell from a height of around 6 meters. After visiting the hospital four days prior, the patient was diagnosed with multiple fractures of the inferior aspect of the right ribs (costa 3-7) as well as a fracture of the right clavicle. However, the patient declined surgery and was made to return home. At that time, the patient did not experience shortness of breath. Currently, the patient is experiencing dyspnea. Blood pressure 138/91 mmHg, heart rate 89 beats per minute, respiration rate 26 times per minute, Spo2 91% room air. The chest x-ray currently shows a right hemothorax. After stabilization, the patient asked to be referred to another hospital for further treatment. Patients with multiple fractured ribs, especially with rib displacement, are at high risk of evolving delayed hemothorax. Close monitoring and observation for several days are necessary.

Background: The standard for managing traumatic pneumothorax (PTX), hemothorax (HTX), and hemopneumothorax (HPTX) has historically been large-bore (LB) chest tubes (>20-Fr). Previous studies have shown equal efficacy of small-bore (SB) chest tubes (≤19-Fr) in draining PTX and HTX/HPTX. This study aimed to evaluate provider practice patterns, treatment efficacy, and complications related to the selection of chest tube sizes for patients with thoracic trauma. Methods: A retrospective chart review was performed on adult patients who underwent tube thoracostomy for traumatic PTX, HTX, or HPTX at a Level 1 Trauma Center from January 2016 to December 2021. Comparison was made between SB and LB thoracostomy tubes. The primary outcome was indication for chest tube placement based on injury pattern. Secondary outcomes included retained hemothorax, insertion-related complications, and duration of chest tube placement. Univariate and multivariate analyses were performed. Results: Three hundred and forty-one patients were included and 297 (87.1%) received LB tubes. No significant differences were found between the groups concerning tube failure and insertion-related complications. LB tubes were more frequently placed in patients with penetrating MOI, higher average ISS, and higher average thoracic AIS. Patients who received LB chest tubes experienced a higher incidence of retained HTX. Discussion: In patients with thoracic trauma, both SB and LB chest tubes may be used for treatment. SB tubes are typically placed in nonemergent situations, and there is apparent provider bias for LB tubes. A future randomized clinical trial is needed to provide additional data on the usage of SB tubes in emergent situations. [ABSTRACT FROM AUTHOR]

Background: Early video‐assisted thoracoscopic surgery (VATS) is the recommended treatment of choice for retained hemothorax (RH). A prospective single‐center randomized control study was conducted to compare outcomes between VATS and thoracostomy tube (TT) reinsertion for patients with RH after penetrating trauma in a resource constrained unit. Our hypothesis was that patients with a RH receiving VATS instead of TT reinsertion would have a shorter hospital stay and lesser complications. Materials and Methods: From January 2014 to November 2019, stable patients with thoracic penetrating trauma complicated with retained hemothoraces were randomized to either VATS or TT reinsertion. The outcomes were length of hospital stay (LOS) and complications. Results: Out of the 77 patients assessed for eligibility, 65 patients were randomized and 62 analyzed: 30 in the VATS arm and 32 in the TT reinsertion arm. Demographics and mechanisms of injury were comparable between the two arms. Length of hospital stay was: preprocedure: VATS 6.8 (+/−2.8) days and TT 6.6 (+/− 2.4) days (p = 0.932) and postprocedure: VATS 5.1 (+/−2.3) days, TT 7.1 (+/−6.3) days (p = 0.459), total LOS VATS 12 (+/− 3.9) days, and TT 14.4 (+/−7) days (p = 0.224). The TT arm had 15 complications compared to the VATS arm of four (p = 0.004). There were two additional procedures in the VATS arm and 10 in the TT arm (p = 0.014). Conclusion: VATS proved to be the better treatment modality for RH with fewer complications and less need of additional procedures, while the LOS between the two groups was not statistically different.

OBJECTIVES End-stage congenital heart disease (CHD) in children with heterotaxy syndrome might necessitate a heart transplant (HTx). An HTx in heterotaxy patients can be associated with several technical (e.g. redo, systemic/pulmonary-venous/situs anomalies, pulmonary artery reconstruction) and extra-cardiac (e.g. ciliary dyskinesia, infections, gastrointestinal) challenges. Our goal was to determine if heterotaxy syndrome is associated with increased early or late transplant risks. METHODS The United Network for Organ Sharing transplant database was merged with the Paediatric Health Information System administrative database to identify children with heterotaxy who received an HTx. Characteristics and outcomes were compared between children with heterotaxy and contemporaneous non-heterotaxy congenital and non-congenital cardiomyopathy control groups. RESULTS After we merged the databases, we divided our cohort of 1122 patients into 3 groups: the heterotaxy (n  = 143), group the non-heterotaxy congenital (n  = 428) group and the cardiomyopathy (n  = 551) group. There were differences in the characteristics between the 3 groups, with the heterotaxy group being comparable to the non-heterotaxy congenital group. The waiting list duration was longer for the heterotaxy than for the non-heterotaxy congenital and cardiomyopathy groups (91 vs 63 vs 56 days, P  < 0.001). Early post-transplant complications were similar for all groups except for operative mortality, which was 1% for the cardiomyopathy and 4% for the heterotaxy and non-heterotaxy congenital groups (P  < 0.001). The post-transplant hospital stay was shorter for the cardiomyopathy (57 days) compared to the non-heterotaxy congenital (99 days) and heterotaxy (89 days) groups (P  < 0.001). Whereas rejection prior to discharge was comparable between the heterotaxy and the CHD groups, it was higher at 1 year for the heterotaxy (22%) than for the non-heterotaxy congenital (19%) and cardiomyopathy (13%) groups (P  < 0.001). Survival at 5 years was superior for the cardiomyopathy (87%) compared to the heterotaxy (69%) and non-heterotaxy congenital groups (78%) (P  < 0.001). For the heterotaxy group, no risk factors affecting survival were identified on multivariable analysis. CONCLUSIONS Regardless of the complexity, an HTx in selected children with heterotaxy is associated with good mid-term outcomes. Despite early results that are comparable to those of other patients with CHD, the increasing rejection rate at 1 year and the relatively accelerated attrition at mid-term warrant further follow-up. Due to database limitations in defining morphologic and surgical details, further work is warranted to delineate anatomical and surgical variables that could affect survival. [ABSTRACT FROM AUTHOR]

We report our experience of managing a massive haemothorax caused by a ruptured, previously unknown, pulmonary arteriovenous malformation (pAVM) at 34 + 5 weeks of gestation, which proved to be a manifestation of hereditary haemorrhagic telangiectasia (HHT), also known as Osler–Weber–Rendu syndrome. The patient underwent an emergency caesarean section under general anaesthesia after placement of a chest tube and gave birth to a healthy infant. A postoperative thoracic computed tomography angiography highlighted the presence of the large pAVM. Transcatheter embolization was performed right after the delivery. Subsequent patient's anamnesis, family history and genetic analysis finally revealed the presence of the syndrome. The aim of our report is to create awareness of this serious condition with potential life-threatening complications, especially in pregnancy. Simple criteria have been published and allow to easily consider HHT and the presence of potential AVM during anamnesis, ideally even before pregnancy. [ABSTRACT FROM AUTHOR]

Patients with a single ventricle circulation continue to be a challenge for a heart transplant. The patients in this cohort, often in poor clinical condition with frequent hepatic and renal impairment having undergone previous multiple surgical procedures, are often allosensitive and consequently have an increased risk of post-transplant complications. Although the most recently published series results are improved, this group of patients, with preserved ventricular function, continues to have a higher mortality rate. Moreover, the operation can be complicated by anatomical differences among the pulmonary arteries. This case report presents a child with tricuspid atresia and pulmonary vascular resistance contraindicating Fontan surgery, unfavourable anatomy of the central pulmonary arteries and in poor clinical condition. An EXCOR ventricular assist device (Berlin Heart) was used for sub- pulmonary mechanical circulatory support and pulmonary bifurcation reconstruction, as a bridge to a transplant.

Background and Objective: This study investigated the accuracy of portable ultrasonography in the diagnosis of traumatic thoracic lesions (hemothorax, pneumothorax, contusions and fractures) compared to Computed Tomography scan (CT-scan). Materials and Methods: This descriptive-analytical cross-sectional study was carried out on 50 patients with thoracic trauma to assess the diagnostic value of portable ultrasonography compared to CT scan. First, ultrasonography of the lungs and CT scan of the chest were performed. Then, the sensitivity, specificity, and positive and negative predictive values were investigated to examine the accuracy and precision of ultrasonography compared to CT scan. Results: In this study, the sensitivity, specificity, and positive and negative predictive values of ultrasonography for detecting thoracic lesions and complications following trauma were 56.82%, 100.0%, 100%, and 91.52%, respectively, with a diagnostic accuracy of 92.37%. Conclusion: The findings of the present study suggested that in the initial evaluation of patients with traumatic thoracic injuries, ultrasonography, in addition to being an accessible, simple, low-cost and feasible method for all patients, has a high diagnostic value, especially in diagnosing pneumothorax and sternum fracture.
