Unlabelled: We report a case of a 63-year-old woman diagnosed with vascular Ehlers-Danlos syndrome (vEDS) who survived two prophylactic surgeries for the dilatation of a thoracoabdominal aortic aneurysm. She initially developed acute type B aortic dissection at the age of 44 years. Five years later, her dissected descending aorta was enlarged to 54 mm; thus, the descending aorta was replaced as the first surgery.

Background: Aortoesophageal fistula (AEF) is a rare but typically life-threatening condition. Although several treatment strategies exist, including conservative treatment with intraluminal stent graft and open thoracic aortic replacement, the overall outcome remains poor, ranging from 16 to 39%. Furthermore, esophageal reconstruction methods vary between hospitals.

Background: Retrosternal gastric tube reconstruction is a common surgical technique for managing esophageal cancer, but it complicates acute type A aortic dissection repair and raises concerns about gastric tube damage.

Case Presentation: A 73-year-old female, who underwent esophagectomy with retrosternal gastric tube reconstruction 6 months ago for esophageal cancer, presented with severe chest pain. Acute type A aortic dissection was confirmed by contrast-enhanced computed tomography, and emergency hemiarch replacement through a median sternotomy was performed, preserving the gastric tube without injury.

Background: During follow-up, aneurysm formation in adults with coarctation of aorta has been reported after undergoing extra-anatomical aortic bypass grafting. Endovascular repair was a reasonable treatment option but there were still complications.

Case Presentation: A 48-year-old male who underwent extra-anatomical aortic bypass grafting, presented with severe back pain and hemoptysis.

Objectives: Thoracic endovascular aortic repair is a widely accepted treatment for chronic aortic dissection because of good early results compared to open surgical repair. We provide early and long-term results of descending thoracic aortic repair for chronic aortic dissection.

Methods: Patients who underwent descending thoracic aortic repair for chronic aortic dissection between January 2012 and December 2020 at Kawasaki Aortic Centre were included in this analysis.

Background: The purpose of this study was to reveal the midterm and long-term mortality rates among patients with thoracoabdominal aortic aneurysm (TAAA) after open TAAA repair and to clarify the effect of aneurysm type on mortality.

Methods: We retrospectively analyzed data for 393 patients (290 men; age, 63.2 ± 12.

Objectives: To evaluate the surgical outcomes of aortic repair via transapical cannulation and the adventitial inversion technique for acute Type A aortic dissection.

Methods: Between 2008 and 2015, a total of 300 patients with acute Type A aortic dissection underwent emergency surgery, consisting of 271 hemiarch repairs and 29 total aortic arch replacements, using transapical cannulation and the adventitial inversion technique at a distal anastomosis. The mean follow-up periods were 31.
