Background: We assess the effectiveness of thoracic endovascular aortic repair (TEVAR) in patients with thoracic artery aneurysm with a retrospective analysis of our experience and a review of the literature.
Methods: Between January 2005 and December 2011, 53 patients with thoracic aortic aneurysm underwent TEVAR. We evaluated the technical success, periprocedural and long-term mortality and morbidity, and follow-up by enhanced computed tomographic scans at 1, 6, and 12 months and annually thereafter.
Results: TEVAR was performed in good general conditions in 62.3% of cases and in emergency conditions in 37.7% of cases. A total of 85 endoprostheses were correctly placed, with technical success of 100%. In 18.8% of cases, a carotid-subclavian bypass was performed; 35.8% of cases required drainage of cerebrospinal fluid. Postoperative mortality was 7.5%, and in all cases patients were treated in emergency regimen. The incidence of major postoperative complications was 9.4%, with 2 cases of paraplegia. At a mean follow-up of 25.6 months, 12 cases (22.6%) of endoleak were observed: 5 cases of type IB endoleak were treated with prosthetic extensions; 7 cases of type II endoleak were not treated. There were no thrombotic occlusions, stent migrations, or fractures.
Conclusion: TEVAR represents an effective option in the treatment of thoracic aortic aneurysms, with good immediate and long-term results.

We present a case of an 80-year-old female who presented with chest pain, vomiting and night sweats a few weeks post thoracic endovascular aortic aneurysm repair (TEVAR). A computed tomography (CT) scan demonstrated a type 1B endoleak for which she underwent a repeat TEVAR. Postoperatively, she developed fever, dysphagia, haematemesis and melaena.

Infectious aortitis is an uncommon but potentially fatal condition that can lead to aortic dissection or rupture. We describe a case of a 69-year-old female who developed a Stanford type B aortic dissection, presumptively caused by Salmonella, which was successfully managed with thoracic endovascular aneurysm repair (TEVAR) and long-term antibiotics. A literature review of 17 reported cases from 2000 to 2024 of aortic dissection secondary to infectious aortitis was conducted.

During dissection of a 70-year-old male donor, several anatomical variations were observed, highlighted by a bilateral variant middle scalene muscle in the superolateral thoracic wall. The variant scalene muscle was traced from the transverse processes of cervical vertebrae to the fourth rib with a pronounced fascial slip. The elongated middle scalene muscle was thick in girth and abnormally wide at its insertion (56.

Background: This study evaluated the midterm outcomes of rapid deployment aortic valve replacement (RDAVR) performed regardless of pathology for various aortic valve diseases at a single center.
Methods: Of the 344 patients who underwent RDAVR using Edwards INTUITY during the study period at our institution, 176 had bicuspid valve diseases (51.2%), 20 had pure aortic regurgitation (5.

Introduction: There is currently no consensus on the optimal surgical approach for the treatment of venous thoracic outlet syndrome (vTOS). Surgical exposures for vTOS decompression include infraclavicular (IC), supraclavicular (SC), paraclavicular (PC), and transaxillary (AX) approaches. The purpose of this study is to provide a comprehensive review of the outcomes and major complications of these four surgical techniques.
