We present a hybrid endovascular approach to a 6.5-cm aneurysm of the right-sided aortic arch with an aberrant left subclavian artery arising from a Kommerell diverticulum, connected to the left pulmonary artery through the ligamentum arteriosum. The two-step procedure consisted of a bilateral carotid-subclavian bypass, followed by an ascending aorta-bicarotid bypass and completed by an endovascular exclusion of the aneurysms by covering the whole aortic arch and its branches. The patient had no complications and is asymptomatic 21 months after surgery. Hybrid procedures may be helpful in complex aortic arch pathologies, reducing complications of challenging open surgery.

Introduction: Blunt traumatic aortic injury (TAI) is a critical condition and a leading cause of mortality in trauma patients, often resulting from high-speed accidents. Thoracic endovascular aortic repair (TEVAR) has developed into the preferred therapeutic approach due to its minimally invasive nature and promising outcomes. This study evaluates the safety and efficacy of TEVAR for managing TAI over a 10-year period at a Level-1 trauma center.

Objective: We present our experience with endovascular Bentall procedure (Endo-Bentall) using a modular valve conduit (Endo-Bentall) in high-risk patients with aortic root pathologies.
Methods: The physician constructed Endo-Bentall device is composed of a self-expanding transcatheter aortic valve (TAVR), aortic endovascular stent graft (TEVAR), and two wire-reinforced fenestrations for coronary artery stenting. The TAVR valve is sutured into an appropriately sized TEVAR graft.

Objective: Over 30% of patients presenting with acute type A aortic dissection (ATAAD) are considered high - risk or inoperable. This study aims to investigate the early and mid-term outcomes of complex endovascular aortic repair of aortic root, ascending aorta, and aortic arch among patients with ATAAD.
Methods: From January 2018 to January 2023, 29 patients who were considered high risk for open operation underwent endovascular aortic repair.

Although open repair remains the mainstream treatment for aortic arch dissection, its surgical complexity and perioperative complications are significant. We developed a novel stentgraft system for less-invasive endovascular aortic arch repair. We successfully performed a total percutaneous transfemoral endovascular repair of aortic arch dissection using a novel off-the-shelf endograft system.
