Article Abstract
We report a case of chronic dissecting thoracoabdominal aneurysm with intraoperative retrograde aortic dissection and rupture at proximal descending aorta, which was successfully treated by echoguided stent-graft insertion. An 82-year old male underwent thoracoabdominal aortic replacement for dilatation of infra-diaphragmatic aorta. Under F-F bypass, his thoracoabdominal aorta was replaced by a Dacron graft with 4-branches. After he weaned from F-F bypass, we found massive bleeding from proximal descending aorta. Trans-esophageal echocardiography (TEE) showed aortic dissection from the clamp site to the distal anastomotic site of the former total arch replacement. We temporary got hemostasis by suture and surgical glue, and anastomosed a 10 mm-graft to the thoracoabdominal main graft as conduit, then inserted and deployed 2 pieces of stent-graft. Direct echo and TEE contributed to the accurate positioning of them. Bleeding was completely controlled. He well recovered without paraplegia. Post-operative computed tomography (CT) showed good positioning and dilatation of the stentgraft and the perfect reverse remodeling of thoracic aorta.

Background: Capecitabine, an oral prodrug of 5-fluorouracil, is widely used for gastrointestinal malignancies. While its coronary toxicity is well documented, large-vessel complications such as aortic dissection are rarely reported.
Case Summary: We present a 65-year-old man with colorectal cancer who developed Stanford type A aortic dissection 3 days after initiating adjuvant capecitabine therapy.

Introduction: Prosthetic valve endocarditis following aortic root replacement (ARR) typically necessitates redo-ARR, which involves complete graft removal, extensive aortic root dissection, and coronary reimplantation. This highly invasive procedure carries substantial surgical risk, including high operative mortality. In select high-risk patients without evidence of prosthetic graft infection, alternative surgical strategies may reduce procedural complexity and improve outcomes.

Department of Vascular Surgery, Asahikawa Medical University, Asahikawa, Hokkaido, Japan.
Introduction: Abdominal compartment syndrome (ACS) is a serious complication that can occur after endovascular aneurysm repair (EVAR) for ruptured abdominal aortic aneurysm (rAAA). Prompt recognition and appropriate management are crucial to improve patient outcomes.
Case Presentation: An octogenarian with an 11-cm rAAA underwent emergent EVAR due to cardiovascular instability.

Diabetic foot ulcers (DFUs) represent a prevalent complication of diabetes, with a lifetime risk ranging from 15% to 25% among diabetic patients. Research indicates that anticoagulation plays a crucial role in the management of newly diagnosed cases of diabetic lower extremity atherosclerotic obliterative disease. However, in the present case, the patient developed dry gangrene in both toes after receiving vasodilator drugs during an emergency intervention for sudden aortic dissection.

Kommerell's diverticulum (KD) combined with a right-sided aortic arch (RAA) and an aberrant left subclavian artery (ALSA) is a rare congenital vascular anomaly causing significant compressive dysphagia. Treatment options, including open surgery, thoracic endovascular aortic repair and hybrid approaches, are debated due to anatomical complexities. We report a 48-year-old female with dysphagia from symptomatic KD, RAA and ALSA, clearly delineated by preoperative computed tomography angiography.
