Since the first identification of Tetralogy of Fallot in 1671, consisting of a combination of anatomical defects including biventricular origin of the aorta, maligned ventricular septal defect, overriding aorta, and narrowing or atresia of the pulmonary outflow tract. The first successful operation consisted of a shunt between the left subclavian artery and pulmonary artery. Following this palliative procedure, complete repair is performed once the patient reaches indicative criteria. Since the first attempts at surgical palliation and repair, techniques and outcomes have improved drastically. Definitive repair of Tetralogy of Fallot consists of a multi-patch closure of any Ventricular Septal Defect along with clearance of any muscular obstructions of the Right Ventricular Outflow Tract and reconstruction of the outflow tract. Current results of Tetralogy of Fallot palliation yield excellent long and short-term results with 5-year freedom from reintervention of 90%. The iterative improvement of repair techniques has greatly reduced intraoperative and postoperative complications. Future innovations such as increased use of percutaneous repair methods and additional data on the benefits of primary repair as opposed to staged palliation will continue to improve patient outcomes.

We present two cases where a transradial-based approach was used to implant thoracic branch aortic endografts to repair aortic aneurysms totally percutaneously. Both procedures were performed electively at a 330-bed suburban community hospital. No complications were associated with either procedure with both patients only requiring overnight observation and being discharged home the next day. With careful patient selection, the transradial through-and-through approach for thoracic endovascular aortic repair using the Gore Thoracic Branch Endoprosthesis provides a totally percutaneous option that can be performed feasibly and safely within a community hospital setting.

We describe a case of endovascular treatment for an iatrogenic left vertebral artery injury after central line catheter placement in a 68-year-old male patient. The patient had a massive pulmonary embolism, and a Swan-Ganz catheter was required to monitor the patient's circulatory condition. However, the catheter was inserted into the left vertebral artery and passed through the left internal jugular vein. Endovascular treatment was indicated due to the patient's poor general health. Complete hemostasis was achieved, and the postoperative course was uneventful without neurologic deficits.

Arterial thoracic outlet syndrome (TOS) following clavicular osteosynthesis/plating is a rare and often unrecognised post-operative complication. In this unique case, both the left subclavian artery and brachial plexus were impinged by an excessively long clavicular fixation screw causing neurogenic and ischaemic symptoms. The poorly matched penetrating screw resulted in left mid-subclavian artery thrombosis with limb threatening distal embolisation to the brachial artery and forearm vessels seven years following his fracture surgery.The patient was initially managed conservatively with six months of anticoagulation. He then underwent planned surgery to remove the plate, impinging screw and formally decompress the thoracic outlet. A supra-clavicular and infra-clavicular approach was used, and with this incision, all compression screws and plate were removed. Anticoagulation was then eschewed after three months without further thromboembolic sequelae and successful dissolution of the established embolism.Subclavian artery impingement may not be immediately apparent during clavicular surgery. This can cause thrombosis over time due to chronic irritation and damage of the vessel wall by the impinging screw. The authors suggest that an upper limb arterial examination with provocative stress manoeuvres of the shoulder, and cross-sectional studies may be performed in symptomatic post-clavicular surgery patients to enable earlier recognition of subclavian artery impingement, prior to the development of late-onset limb-threatening ischaemia. This case shows that subclavian artery thrombus due to an impinging screw can present with limb-threatening ischaemia. Although initially managed conservatively with anticoagulation, definitive treatment required surgical removal of the impinging metalwork which allowed the patient to stop anticoagulation, resolved his pain and improved shoulder function.

This article, published in the journal Thoracic & Cardiovascular Surgeon, discusses the use of extra-anatomic left subclavian artery (LSA) bypass in aortic arch surgery. The study reviewed 342 consecutive aortic repair patients over a 4.5-year period and found that in a subgroup of 33 patients, LSA bypass was performed using prostheses with a perfusion side-arm. The results showed that all survivors of the repairs showed no clinical left arm ischemia and had a patent angio-CT. However, the mortality rate was higher in cases where EA LSA bypass was used due to neurological and other malperfusion disease. The authors conclude that EA LSA bypass is a valuable solution for LSA revascularization in total arch repair. [Extracted from the article]

Abstract Background TAVI via the left subclavian artery is considered a bail-out strategy in cases where a transfemoral approach is not feasible. However, since this route is only scarcely used, major complications can arise. We describe such an adverse course and present our proceeding. Case presentation A 65-year-old man with severe aortic valve stenosis (AS) was referred for transcatheter aortic valve implantation (TAVI) via left subclavian artery. After uneventful deployment of the TAVI prosthesis, consequent valve assessment with transeosophageal echocardiography and angiography showed a highly mobile and tubular structure shifting within the valve. We went for a surgical extraction via sternotomy on cardiopulmonary bypass (CPB). A 6 cm longish intimal cylinder was hassle-free extracted. 4 days postoperatively the left sided radial pulse was missing. In a subsequent computed tomography angiography (CTA) scan a proximal dissection as well as an intimal flap, causing a subtotal stenosis of the left subclavian artery, was detected. Consecutively the intimal cylinder was removed using a Fogarty-balloon. Pre-discharge control revealed recurrence of peripheral radial pulse and an unimpeded function of the TAVI prosthesis. The patient presented no sequela at discharge. Conclusion Though TAVI is a well-advanced technique complications are not completely avertable. It is thus advisable to have patients discussed in the heart team encompassing all potentially involved specialties.

We describe a 74-year-old male with delayed onset of acute left upper extremity ischemia after blunt chest trauma with left clavicular fracture, resulting in left subclavian artery injury, including pseudoaneurysm formation, intramural hematoma, thrombosis, and distal embolization to the brachial artery. The patient presented with left upper extremity pain, forearm and hand numbness, and digital cyanosis. The patient was treated with a hybrid approach, consisting of transfemoral percutaneous deployment of a covered stent in the left subclavian artery and concomitant surgical thrombectomy of the left brachial artery, resulting in excellent recovery and resolution of symptoms.

Subclavian artery aneurysm (SAA) is a rare condition seen in less than 1% of peripheral artery aneurysms. It is usually asymptomatic. However, it may become symptomatic as a result of pressure on the surrounding organs due to the progressive growth of the aneurysm. The standard treatment for SAA is surgery. In this article, we wanted to present a 63-year-old male patient who presented with the complaint of shortness of breath and was operated on with the diagnosis of Right Subclavian artery true aneurysm on thoracic CT angiography.

ABSTRACT Introduction: The aim of this study was to present the mid-term results of patients who had undergone a carotid-subclavian bypass surgery after a thoracic endovascular aortic repair (TEVAR) stent-graft implantation with proximal landing at zone 2 of the aorta. Methods: A total of 66 patients had undergone TEVAR and carotid-subclavian bypass between January 2015 and May 2020 at our clinic. Five of these patients were lost to follow-up, so 61 patients were included in this retrospective study. At follow-up visits, patency of the carotid-subclavian bypass grafts was evaluated with physical examination and radiological imaging. Results: The mean follow-up time was 15.11±12.29 months (ranging from 1 to 56 months). There were 3 (4.91%) in-hospital deaths of patients admitted with bilateral lower limb and visceral malperfusion. There were also 2 (3.27%) deaths unrelated to the procedure. Carotid-subclavian graft occlusion occurred in 3 (4.91%) patients. The occlusion was detected with radiological imaging within a period of 12 to 24 months. The graft patency rate was 100% in the first 12 months. The mean graft patency time (survival) was 52.56±2.10 months. Conclusion: Periprocedural carotid-subclavian bypass surgery with synthetic grafts is a recommended procedure with high patency and acceptably low mortality and morbidity rates in TEVAR.

Gun violence reached a 20-year peak in 2020, with the first-line treatment of axillosubclavian vascular injuries (SAVIs) remaining unknown. Traditional open exposure is difficult and exposes patients to iatrogenic venous and brachial plexus injury. The practice of endovascular treatment has been increasing. We performed a retrospective analysis of SAVIs at a level I trauma center. Seven patients were identified. Endovascular repair was performed in five patients. Technical success was 100%. The early results suggest that endovascular treatment of trauma-related SAVIs can be performed safely and effectively. However, complications such as stent thrombosis or occlusion can occur, demonstrating the need for surveillance.

Subclavian artery pseudoaneurysm due to intravenous drug use is a rare pathologic entity. A 6.6-cm left subclavian artery pseudoaneurysm immediately distal to the origin of the vertebral artery was discovered in a 39-year-old man with neck swelling, bacteremia, and a history of intravenous drug use. The pseudoaneurysm was resected through a median sternotomy and left supraclavicular incision, without reconstruction. This operative approach was opted for given the presence of infection and the ongoing intravenous drug use.

Abstract The subclavian artery is a significant branch of the aortic arch. We present a rare case of a bilateral variation in the branching pattern of the subclavian artery, observed in an adult male cadaver aged 70 years. On both the sides of the neck, all the branches of the subclavian artery took their origin from its first part. There was a rare occurrence of a cervicodorsoscapular trunk, which gave rise to superficial cervical, suprascapular, and dorsal scapular arteries. The same branching pattern was observed on the left side of the neck, with the presence of another cervicodorsoscapular trunk. Thyrocervical trunk and transverse cervical artery were both absent from the cervical region bilaterally. The inferior thyroid artery was a direct branch from the subclavian artery. Knowledge regarding variations of the subclavian artery is very important as lateral cervical region arteries are important for flap harvesting in plastic and reconstruction surgery. Preoperative radiologic evaluation of pedicles might help in choosing the optimal flap design, prevent ischemic complications, and help to improve overall treatment outcomes.

Background: Abnormal tumor vascularization and escalating tumor size represent two major impediments that make cancer surgery impossible or complicated. Case presentation: Herein, we report the case of a giant thymoma (type AB) in a 58-year-old woman who presented with cough and yellow sputum. The thymoma grew extensively from the neck to the upper mediastinum. The patient exhibited an aberrant right subclavian artery and a non-recurrent inferior laryngeal nerve. Intraoperative nerve monitoring facilitated the identification and preservation of vital nerves spanning the neck and chest, including the non-recurrent inferior laryngeal nerve. Furthermore, the tumor was divided naturally along the constriction, and a good field of view was acquired to identify abnormal right subclavian arteries and nerves that ran deep in the tumor and surgical field. The tumor was safely removed without complications using intraoperative nerve monitoring, and the thymoma that grew extensively from the neck to the upper mediastinum and was associated with an aberrant right subclavian artery was resected. Conclusion: Intraoperative nerve monitoring was helpful in identifying the non-recurrent inferior laryngeal nerve and left recurrent laryngeal nerve. [ABSTRACT FROM AUTHOR]

Abstract Background Subclavian artery aneurysms are rare but may cause life-threatening complications. Surgical repair has been performed as a treatment of choice, but recently, with the development of endovascular treatment, many endovascular repairs have been performed to prevent surgical complications. Case presentation A patient undergoing endovascular repair with a subclavian artery aneurysm was diagnosed with a type II endoleak with an enlarged aneurysmal sac. Surgical repair was performed to remove the aneurysmal sac compressing the adjacent organs. Conclusions The highly mobile subclavian artery has abundant collaterals. Therefore, regular follow-up is essential for endovascular repair. Surgical repair is effective when adjacent organs are compressed by the aneurysm sac.

Axillosubclavian artery injury is relatively uncommon; however, it is related to a high rate of morbidity and mortality. Although open repair as well as endovascular techniques have been proposed for the treatment of axillosubclavian artery injury, the ideal approach is still under investigation. We present a case of a 20-year-old patient who suffered from complete subclavian artery transection, following blunt thoracic trauma. Using percutaneous access, a balloon catheter was inflated under fluoroscopy, in the origin of his affected subclavian artery ceasing the haemorrhage, thus immediately afterwards he was submitted to arterial bypass. The combination of endovascular and open repair ensured his life and limb salvage while the complications of an otherwise extensive dissection were obviated.

The treatment of aortic pathologies is always challenging for vascular surgeons. Currently, thoracic endovascular aortic repair (TEVAR) is the first treatment option for thoracic aortic pathologies. Left subclavian artery (LSA) coverage during TEVAR can be selectively done; however, revascularization is preferred to reduce the risk of neurological or ischemic complications according to current guidelines. The chimney technique, hybrid operations, back table or in situ fenestrations are assistive TEVAR techniques. Herein, we present three different scenarios in zone 2 landing treated with surgeon-modified fenestrated stent graft (SMFSG). The use of SMFSG for LSA revascularization during TEVAR is feasible, cost-effective, fast, and effective. Durability is of great concern, and the most suitable treatment modality for zone 2 landing necessitates randomized-controlled studies and long-term durability issues.

BackgroundGiant true subclavian artery aneurysms (SAAs) (>5 cm) are rare. Technical and anatomical considerations complicate the endovascular treatment of SAAs and pose some challenges. Here, we present a giant right SAA that was successfully excluded using stent grafts with the pull-through technique after two interventional steps and discuss the pull-through technique details as well as the lessons to be learned from this case.MethodsA 50-year-old man presented at our department complaining of dyspnea and hoarseness. Computed tomography angiography (CTA) showed a giant right SAA with partial intraluminal thrombus and severe angulated aneurysm necks originating from the proximal right subclavian artery, approximately 70 × 71 mm in size.OutcomesAn 8 × 100-mm Gore Viabahn was selected to exclude the SAA. A decision was made to stabilize the wire tension using the pull-through technique. Final angiography showed that the SAA was essentially excluded, and slight endoleak was observed. At 6 months, imaging showed that the aneurysm was not obviously shrinking, there was still an endoleak and stent graft dislodgement was observed. Angiography confirmed a type Ia endoleak, which was managed by the placement of a 10 × 50-mm Gore Viabahn, again with the assistance of the pull-through technique. At the 25-month follow-up, CTA showed that the SAA was satisfactorily excluded, with no endoleak, and the SAA was reduced in size.ConclusionsEndovascular treatment of SAAs is a safe, reliable and minimally invasive approach. The pull-through technique may improve wire tension and device stabilization. Additionally, size selection and positioning should be reappraised under a severely angulated aneurysm neck.

ABSTRACT Introduction: In this study, we aimed to present three different methods for symptomatic aberrant right subclavian artery (ARSA) surgery. Methods: We identified 11 consecutive adult patients undergoing symptomatic and/or aneurysmal ARSA repair between January 2016 and December 2020. Symptoms were dysphagia (n=8) and dyspnea + dysphagia (n=3). Six patients had aneurysm formation of the ARSA (mean diameter of 4.2 cm [range 2.8 - 6.3]). All data were analyzed retrospectively. Results: Median age of the patients (7 females/4 males) was 55 years (range 49 - 62). The first four patients (36.4%) underwent hybrid repair using thoracic endovascular aortic repair (TEVAR) and bilateral carotid-subclavian artery bypass (CScBp). Three patients (27.2%) were treated by open ARSA resection/ligation with left mini posterolateral thoracotomy (LMPLT) and right CScBp. And the last four patients (36.4%) underwent ARSA resection/ligation with LMPLT and ascending aorta-right subclavian artery bypass with upper mini sternotomy (UMS). Two of the four patients who underwent TEVAR + bilateral CScBp had continuing dysphagia cause of persistent esophageal compression. Brachial plexus injury developed in one of three patients who underwent LMPLT + right CScBp. Pleural effusion treated with thoracentesis alone was observed in one of four patients who underwent UMS + LMPLT. Conclusion: Among the symptomatic and/or aneurysmal ARSA treatment approaches, surgical and hybrid methods are used. There is still no consensus on how to manage these patients. In our study, we recommend the UMS + LMPLT method, since the risk of complications with anatomical bypass is less, and we have more successful surgical results.

Mediastinal germ cell tumor (MGCT) is a relatively rare tumor. Complete resection after chemotherapy is a standard treatment against this disease. However, the risk factors of incomplete resection are unclear. Therefore, we analyzed survival rates and risk factors for incomplete resection based on preoperative imaging. We retrospectively reviewed the medical records of patients (n = 56) with MGCT operated at National Cancer Center Hospital, and analyzed preoperative computed tomography (CT) data in terms of relationship of the tumor and vessels, and investigated survival rate and risk factors for incomplete resection. A total of 56 patients underwent resection of MGCT. The 5-y progression-free survival (PFS) and overall survival (OS) were 79% and 83%. In multivariate analysis, complete resection was the only significant prognostic factor for better PFS (hazard ratio (HR) = 9.083, P = 0.00021) and OS (HR = 5.519, P = 0.0445). The preoperative CT finding of arteries (including the aorta, right brachiocephalic artery, left common carotid artery, and left subclavian artery) surrounded by the tumor was a predictor of incomplete resection (odds ratio = 10.089, P = 0.049). Complete resection is essential for improving the survival of MGCT, and the risk stratification using preoperative CT imaging brings important information to achieve the complete resection.

Case: A 43-year-old woman presented with pain, paresthesia, and coldness of the right upper extremity suggestive of the diagnosis of thoracic outlet syndrome. Three-dimensional computed tomography angiography revealed that the right subclavian artery was constricted because it traveled over an abnormal first rib. After anticoagulation and antithrombotic therapy, the patient underwent resection of the abnormal first rib. Postoperative angiography documented improvement over time of the poststenotic dilatation and recanalization of the subclavian artery capable of delivering almost normal distal flow. Conclusion: Arterial reconstruction is not always necessary for the treatment of arterial thoracic outlet syndrome associated with poststenotic dilatation of the subclavian artery.

Open in new tab Download slide Open in new tab Download slide OBJECTIVES Vascular rings are rare anomalies of congenital heart disease that cause respiratory and gastrointestinal symptoms. This study assessed the long-term outcomes of patients with vascular ring division. METHODS A multi-institution retrospective review of 371 patients with vascular rings undergoing surgical division at 3 paediatric cardiac institutions between November 2007 and October 2019 was performed. RESULTS The complete vascular rings consisted of a double aortic arch (24.5%), right aortic arch with left ligamentum arteriosum (36.7%) and left aortic arch, with right ligamentum arteriosum (0.5%). The incomplete vascular rings consisted of a pulmonary artery sling (22.9%), left aortic arch with aberrant right subclavian artery (15.1%) and innominate artery compression syndrome (0.3%). Respiratory symptoms included stridor (71.4%), wheezing (49.1%), coughing (31.5%), gastrointestinal symptoms included choking (12.4%), dysphagia (3.2%) and emesis (1.9%). Only one patient died after discharge, yielding a late mortality rate of 0.3% (1/360). The 10-year overall survival rate was 96.8%. Postoperative complications were reported in 51 patients, 15 of whom required reoperation. The 10-year freedom from reoperation rate was 95.9%. Follow-up was completed in 95.4% (354/371) of patients, with a mean follow-up time of 4.3 ± 2.9 years (range from 1 to 13 years). Twenty patients (5.6%) experienced residual symptoms during long-term follow-up. CONCLUSIONS The outcomes of vascular ring division are excellent. A Kommerell diverticulum >1.5 times the aberrant left subclavian artery origin is an operative indication for primary resection. Tracheomalacia is a risk factor for reoperation and residual symptoms, and preoperative fibrobronchoscopy is important for evaluation. [ABSTRACT FROM AUTHOR]

The article discusses the prevalence and management of aberrant right subclavian artery (ARSA) in infants. ARSA is a common finding, occurring in about 1.5% of karyotypically normal fetuses. While it is often detected prenatally, the need for surgical intervention is rare, especially if there are no other associated genetic abnormalities or symptoms. The study found that out of 528 prenatally diagnosed cases, only seven underwent surgery. The most common symptoms associated with ARSA were noisy breathing/stridor, dysphagia, and recurrent chest infections. Overall, the study suggests that expectant parents can be reassured that postnatal complications are unlikely if their fetus is diagnosed with ARSA and has an otherwise normal heart.

Abstract Coronary subclavian steal syndrome is an uncommon cause of angina in patients with a previous coronary artery bypass graft procedure. The patient had chest pain with the exertion of the left upper limb, difference in blood pressure between the left and right arm, occlusion at the ostium of the left subclavian artery. He underwent carotid subclavian bypass surgery that was successful in relieving symptoms. On the other hand, the patient had an embolic stroke related to the procedure and further assessment may be necessary.

Mycotic subclavian artery aneurysms are rare but challenging pathology. We report a 67-year-old woman who presented with recurrent bacteremia secondary to chronic clavicular osteomyelitis. Imaging demonstrated a right subclavian artery aneurysm near the innominate artery bifurcation and in close proximity to the infected clavicle. Owing to the anatomic location, among other factors, she underwent open repair using a rifampin-soaked Dacron conduit. Analysis of the aneurysm wall identified bacteria consistent with intraoperative bone and blood cultures. Contributions from multiple surgical and medical specialties provided a favorable, long-term outcome for the patient.

We report a case of autologous breast reconstruction in which a thoracodorsal vessel was used as a recipient vessel after a hypoplastic internal mammary vessel was found on preoperative computed tomography (CT) angiography. A 46-year-old woman with no underlying disease was scheduled to undergo skin-sparing mastectomy and breast reconstruction using a deep inferior epigastric artery perforator flap. Preoperative CT angiography showed segmental occlusion of the right subclavian artery with severe atherosclerosis and calcification near the origin of the internal mammary artery, with distal flow maintained by collateral branches. The thoracodorsal artery was selected to be the recipient vessel because CT showed that it was of adequate size and was not affected by atherosclerosis. The patient experienced no postoperative complications, and the flap survived with no vascular complications. The breasts were symmetrical at a 6-month follow-up. This case highlights that preoperative vascular imaging modalities may help surgeons avoid using diseased vessels as recipient vessels in free flap breast reconstructions.

The article describes the clinical experience of treatment of life-threatening pathology by minimally invasive methods. There is a long-term stable positive result after the operation. The introduction of new technologies in medicine minimizes the risk of postoperative complications, contributing to a favorable outcome of the disease.

Objective: In this retrospective study, we presented the results of Castor single-branched stent-graft in a small series of patients with acute type B aortic syndrome and aberrant right subclavian artery (ARSA). Methods: Between January 2019 and November 2019, 5 patients were diagnosed with acute type B aortic syndrome and ARSA (4 patients with intramural hematoma and ARSA, 1 patient with type B aortic dissection and ARSA). All the patients underwent thoracic endovascular aortic repair (TEVAR) using Castor single-branched stent-graft. In-hospital and 3-month outcomes were collected. Results: The mean operative time was 116 ± 20.43 minutes (range 90-145). All the TEVAR procedures were successfully performed without conversion to open surgery (100% success rate). All the ARSAs of the 5 patients were revascularized in situ by Castor single-branched stent-grafts. No deaths and complications were observed in the 3-month follow-up. The maximal diameters of diseased aortas in the 4 patients with IMH decreased 3 months after TEVAR. The false lumen in the graft-covered segment was completely thrombosed in the patient with type B aortic dissection. Conclusions: Castor single-branched stent-graft may be a good choice in treatment of acute type B aortic syndrome and aberrant right subclavian artery. [ABSTRACT FROM AUTHOR]

Abstract Background Bleeding of the subclavian artery is a fatal condition. Adhesion between the pleura and staple line may develop after surgical treatment of pneumothorax, and collateral arteries often develop from the subclavian artery toward the adhesion at the lung apex; however, atraumatic tearing and bleeding of these collateral arteries into the extrapleural and intrathoracic cavities is rare. Case presentation A 70-year-old man visited the hospital for evaluation of left chest pain. Contrast-enhanced chest computed tomography showed a huge tumor in the left apex of the lung. It was suspected to be an extrapleural huge hematoma, and it ruptured into the thoracic cavity. Bleeding from the left subclavian artery was suspected; therefore, emergency angiography was performed. Angiography showed some collateral circulation from the left subclavian artery to the apex of the left lung. Distal and proximal bleeding points were identified. The distal bleeding point was embolized using coils. The proximal bleeding point was blown out, and stents were placed in the left subclavian artery. He had undergone pneumothorax surgery 20 years previously, and the present bleeding episode was strongly suspected to be associated with that surgery. The collateral circulation from the subclavian artery could have developed because of post-pneumothorax inflammation, eventually rupturing and bleeding into the extrapleural space. Conclusions This report described an important case of atraumatic subclavian artery bleeding considered to have been caused by surgical treatment of pneumothorax 20 years previously. Emergency angiography and percutaneous stent placement or coil embolization should be considered first in such cases.

Resumo A compressão da artéria subclávia no desfiladeiro torácico é um fenômeno amplamente conhecido. Anormalidades ósseas, como a pseudoartrose da clavícula, podem raramente causar compressão arterial a esse nível. A pseudoartrose pode desenvolver-se em decorrência de um trauma, que é a forma mais comum, ou ser congênita. Os autores descrevem o caso de uma paciente de 44 anos com quadro de isquemia crítica de membro superior direito. Apresentava história de fratura não tratada de clavícula direita aos 9 meses de idade que evoluiu com pseudoartrose e compressão extrínseca com oclusão da artéria subclávia. O segmento da clavicula acometido pela pseudoartrose foi ressecado e realizada uma tromboembolectomia tardia das artérias subclávia, braquial e distais, com boa evolução.

Abstract Aortic arch anomalies are not clinically important unless they cause compression symptoms due to aneurysmatic dilatation. Aortic anomalies need to be treated when they cause complex thoracic aortic diseases, and the treatment approach has evolved over time from open surgical methods, which have high mortality and morbidity rates, to hybrid methods. A case of a 68-year-old male patient with complex aortic arch anomaly treated with hybrid arch repair is reported in this study. Aortic branches were common carotid trunk and aberrant right subclavian artery with a saccular aneurysm.

The arterial form of thoracic outlet syndrome is rare and is associated with anatomic anomalies, generally a cervical rib. It has a varied range of manifestations. The aim of this article is to describe two cases with different clinical presentations: microembolization and aneurysm. A cervical rib was present in both cases. Diagnosis was made on the basis of history, physical examination, postural maneuvers, and X-rays. Computed tomography angiography provided the anatomic detail necessary to plan surgery. Surgical treatment was performed via supraclavicular access, successfully, in both cases. [ABSTRACT FROM AUTHOR]
