Concomitant rupture of the subclavian vessels and the left main bronchus caused by blunt trauma is a serious condition. Moreover, the diagnosis of a tracheobronchial injury with rupture of the subclavian vessels can be difficult. This report describes the case of a 33-year-old man who suffered from blunt trauma that resulted in the rupture of the left subclavian artery and vein. The patient underwent an operation for vascular control. On postoperative day 3, the left main bronchus was found to be transected on a computed tomography scan and bronchoscopy. The transected bronchus was anastomosed in an end-to-end fashion. He recovered without any notable problems. Although the bronchial injury was not detected early, this case of concomitant rupture of the great vessels and the airway was successfully treated after applying extracorporeal membrane oxygenation.

Background: Re-expansion pulmonary edema (REPE) is a lethal complication that can occur after inserting a chest tube. However, no clinical research reports have analyzed the progress and treatment of REPE, except for a single case report review. We retrospectively analyzed the common clinical characteristics, clinical progress, and treatment outcome of REPE with respiratory failure. Methods: We retrospectively reviewed the clinical features, treatment, and outcomes of eight patients with REPE who required ventilator care from March 2004 to March 2018. Results: The mean PaO 2 /FiO 2 ratio of the patients immediately after intubation was 106.5±20.2 (range, 75–128), which indicated severe hypoxia in all cases. On the first day of treatment, most of the patients showed improvement in hypoxia symptoms, and most improved to the extubation level on day 3. The mean duration of ventilator use was 2.5±0.8 days (range, 1–4 days), and the mean duration of inotropic drug use was 1.1±0.7 days (range, 0–2 days). The mean intensive care unit (ICU) stay was 4.4±1.5 days (range, 3–8 days). No deaths were recorded during the study period, and no cases of permanent complications due to REPE were observed. Conclusions: REPE requiring ventilator care is a lethal disease. However, continued development of ICU care has dramatically decreased mortality. Low positive end-expiratory pressure (PEEP), low tidal and high O 2 ventilator care represents the most appropriate treatment for REPE.

Purpose: Tracheobronchial injuries caused by trauma are rare, but can be life threatening. The objective of this study was to evaluate the surgical outcome for patients with tracheobronchial injuries and to determine the difference, if any, between the outcomes for patients with penetrating trauma and those for patients with blunt trauma. Methods: From January 2010 to June 2015, 40 patients underwent tracheobronchial repair surgery due to trauma. We excluded 14 patients with iatrogenic injuries, and divided the remaining 26 into two groups. Results: In the blunt trauma group, injury mechanisms were motor vehicle accident (9 cases), free falls (3 cases), flat falls (1 case) and mechanical injury (1 case). In the penetrating trauma group, injury mechanisms were stab wounds (10 cases), a gunshot wound (1 case) and a stab wound caused by metal pieces (1 case). The mean RTS (Revised Trauma Score) was 6.89±1.59 (range: 2.40-7.84) and the mean ISS (Injury Severity Score) was 24.36±7.16 (range: 11-34) in the blunt group; the mean RTS was 7.56±0.41 (range: 7.11-7.84), and the mean ISS was 13±5.26 (range: 9-25) in the penetrating trauma group. In the blunt trauma group, 9 primary repairs, 1 resection with end-end anastomosis, 2 lobectomies, 1 sleeve bronchial resection and 1 pneumonectomy were performed. In the penetrating trauma group, 10 primary repairs and 2 resections with end-end anastomosis were performed. Complications associated with surgery were found in one patient in the blunt trauma group, and one patient in the penetrating trauma group. No mortalities occurred in either groups. Conclusion: Surgical management of a traumatic tracheobronchial injury is a safe procedure for both patients with a penetrating trauma and those with a blunt trauma. [ J Trauma Inj 2016; 29: 1-7 ]

【Penetrating neck trauma involving spinal cord injury is relatively uncommon, but can be life-threatening. We report a case of 59-year-old female who presented with hypotension after stab injury self-inflicted with a scissor to her neck. Although Open removal of the scissor and control of bleeding were successfully done, penetration of spinal cord resulted in a neurologic impairment.】

There are various methods for approaching the aortic arch, such as median sternotomy or lateral thoracotomy. However, accessing the site of distal anastomosis is problematic when the distal arch is extensively involved. We report a case of extended aortic arch replacement and coronary artery bypass through the L-incision approach.

Chest drainage systems are usually composed of chest tube and underwater-seal bottle. But this conventional system may restrict patients doing exercise and give clinicians obscure data about when to remove tubes because there is no objective indicator. Recently developed digital chest drainage systems may facilitate interpretation of the grade of air leak and make it easy for clinicians to decide when to remove chest tubes. In addition, with combination of wireless internet devices, monitoring and managing of drainage system distant from the patient is possible.Sixty patients of primary pneumothorax were included in a prospective randomized study and divided into two groups. Group I (study) consisted of digital chest drainage system while in group II (control), conventional underwater-seal chest bottle system was used. Data was collected from January, 2012 to September, 2013 in Eulji University Hospital, Daejeon, Korea.There was no difference in age, sex, smoking history and postoperative pain between two groups. But the average length of drainage was 2.2 days in group I and 3.1 days in group II (P0.006). And more, about 90% of the patients in group I was satisfied with using new device for convenience.Digital system was beneficial on reducing the length of tube drainage by real time monitoring. It also had advantage in portability, loudness and gave more satisfaction than conventional system. Moreover, internet based digital drainage system will be a good method in thoracic telemedicine area in the near future.

Eosinophilic pleural effusion (EPE) is characterized by greater than 10% eosinophilia and is frequently associated with air and/or blood in the pleural cavity. Primary spontaneous pneumothorax (PSP), defined as the spontaneous presence of air in the pleural space, is one of the most common causes of EPE. Recent studies have shown that type 2 immune responses play important roles in eosinophilic airway inflammation resulting in pleural pathology.To determine the predominant immune responses associated with PSP in humans, and to examine whether IL-33, thymic stromal lymphopoietin (TSLP), or type 2 innate lymphoid cell (ILC2)-mediated immune responses are associated factors.Eosinophil-associated cytokines were measured in the pleural fluid of patients with PSP and control subjects. Th2 cell and ILC2 responses in the pleural cavity and peripheral blood were also evaluated by in vitro restimulation and intracellular cytokine staining of T cells and ILC2s in patients with PSP (n = 62) and control subjects (n = 33). IL-33-mediated IL-5 production by ILC2s was also evaluated.Significantly higher concentrations of IL-5 and eotaxin-3 were detected in the pleural fluid of patients with PSP, in addition to significantly higher concentrations of IL-33 and TSLP. Although IL-5 production was induced by IL-33 treatment of ILC2s, other Th2 cell-mediated immune responses were not detected.Our results indicate that innate immune responses characterized by the production of IL-33, TSLP, and IL-5 are associated with the development of EPE in PSP by an ILC2-dependent and Th2-independent mechanism.

Lung transplantation is a viable option for patients with chronic obstructive pulmonary disease (COPD), and emphysema is the most common indication to undergo lung transplantation. A total of seven lung and one heart-lung transplantations were performed between July 1996 and June 2004 at the Yongdong Severance Hospital, and herein, three emphysema patients who underwent single lung transplantations are reviewed. There were 2 males and 1 female, with a mean age of 50 years (35, 57 and 58 years). They all underwent an operation, without cardiopulmonary bypass, and there was no operative mortality. The mean survival was 12 months (4 months, 15 months and 17 months) and all succumbed to death due to activation of pulmonary tuberculosis, post-transplantation lymphoproliferative disease and cytomegalovirus (CMV) gastritis associated with asphyxia. Infection was the most common postoperative complication, resulting in longer hospital stays, higher medical expenses and shorter survival rates, necessitating aggressive prophylactic management. The accumulation of experience, modifications to operative procedures and perioperative care may lead to improved early and long-term survival in patients with emphysema undergoing single or bilateral lung transplantations.

The Nuss procedure is a newly developed operative method for minimally invasive repair of pectus excavatum in pediatric patients. However, the surgical indication for this procedure has been extended into adult patients. The aim of this study was to assess the surgical outcome of the Nuss procedure in different age groups and to analyze its feasibility in the adult population.From December 1999 to March 2003, 51 patients (40 males and 11 females) with pectus excavatum underwent the Nuss procedure. We classified patients into three groups based on age (pediatric, adolescent, and adult), retrospectively analyzed demographic, intraoperative and postoperative data, and compared outcomes among each group.Mean operation time was 52.0 +/- 22.9 minutes, 80.4 +/- 27.4 minutes, and 127.3 +/- 44.9 minutes in the pediatric, adolescent, and adult groups, respectively (p0.001). Postoperative complications occurred in 3 of 27 patients (11.1%) in the pediatric group and in 7 of 12 patients (58.3%) in both the adolescent and adult groups (p = 0.002). Reoperations were performed due to complications in 1 of 27 patients (3.7%) in the pediatric group, 2 of 12 patients (16.6%) in the adolescent group, and 5 of 12 patients (41.7%) in the adult group (p = 0.001).The Nuss procedure is highly recommended in pediatric patients with pectus excavatum. However, in adults it is necessary to select patients carefully because of the longer operation time and higher incidence of complications associated with the procedure in this population.

Background The prognosis of acute lung injury (ALI) after pneumonectomy is poor, with reported mortality rates of 30-100%. Neutrophil elastase inhibitor (NEI) is known to prevent lung injury caused by neutrophil elastase and improve lung function in ALI. We evaluated the effect of NEI on ALI after pneumonectomy. Methods We analyzed nine patients who required ventilator care due to ALI after pneumonectomy. Five of these patients underwent conventional ventilator care (group I), and four patients underwent ventilator care and were administrated NEI (group II). We retrospectively analyzed the lung injury score (LIS) for 10 days after intubation. Results The LIS before intubation satisfied the diagnostic criteria of ALI or acute respiratory distress syndrome (ARDS) in all patients. After intubation, the LIS improved in both groups. But, as times went on, the mean value of the LIS in group II was lower compared to group I. In group I, only one patient underwent extubation. In group II, extubation was possible in three patients. Mortality rates were 80% in group I and 25% in group II. Conclusions We conclude that NEI may improve the lung function, shorten the duration of mechanical ventilation, and reduce mortality in patients with ALI after pneumonectomy.
