Objectives: This study aimed to evaluate the surgical outcomes of composite-valve root replacement with bioprosthesis (b-CVRR) after acute type A aortic dissection (AAAD) repair.
Methods: We included 41 patients who underwent b-CVRR after surgery for AAAD from 2007 to 2022. We excluded seven patients with VSRR, three with mechanical valve use, one with mycotic aneurysm, and one with cardiopulmonary resuscitation.
Purpose: To examine the surgical findings of ruptured abdominal aortic aneurysm (RAAA) based on the open-first strategy in the last decade, and to analyze the predictors of in-hospital mortality for RAAA in the endovascular era.
Methods: The subjects of this retrospective study were 116 patients who underwent RAAA repair, for whom sufficient data were available [25% female, median age 76 (70-85) years]. Sixteen (13.
Objectives: The optimal treatment for acute type A aortic dissection (AAAD) with thrombosed false lumen (T-FL) of the ascending aorta remains controversial. The goal of this study was to evaluate clinical outcomes of initial medical treatment (IMT) and the effectiveness of thoracic endovascular aortic repair (TEVAR) for AAAD with T-FL.
Methods: We retrospectively analysed 60 patients with AAAD with T-FL.
Objectives: The optimal indications and contraindications for thoracic endovascular aortic repair of retrograde Stanford type A acute aortic dissection (R-AAAD) are not well known. The goal of this study was to determine the outcomes of thoracic endovascular aortic repair for R-AAAD at our institution and to discuss optimal indications.
Methods: The medical records of 359 patients admitted to our institution for R-AAAD between December 2016 and December 2022 were reviewed, and 83 patients were finally diagnosed with R-AAAD.
Background: A 57-year-old woman was diagnosed with Kommerell's diverticulum in the setting of a right aortic arch on computed tomography.
Case Report: Although asymptomatic, the maximum diameter of the aneurysm was 55 mm; thus, she underwent surgery to prevent rupture of the aneurysm. A bypass was constructed from the left common carotid artery to the left subclavian artery.
Background: A 64-year-old woman presented with dilatation of the distal aortic arch secondary to chronic type B aortic dissection.
Case Report: The patient underwent fenestrated thoracic endovascular aortic repair (TEVAR) for closure of the entry site, and reconstruction of the left subclavian artery with a covered stent. On the 40th postoperative day, a retrograde type A aortic dissection (RTAD) was observed on computed tomography and she underwent emergency surgery.
