Staged Hybrid Repair Including Abdominal Branches Bypass Grafting for Crawford TypeⅡ Thoracoabdominal Aortic Aneurysm:Report of a Case

A 64-year-old female with a diagnosis of Crawford typeⅡ thoracoabdominal aortic aneurysm( TAAA) including enlargement of the ascending aorta underwent a staged hybrid repair including visceral artery debranching thoracic endovascular aortic repair( TEVAR). First, total arch replacement with elephant trunk method was performed, followed by TEVAR for the descending thoracic aorta, and finally visceral artery debranching TEVAR for the thoracoabdominal aorta. Complications such as spinal cord infarction did not occur throughout the procedure. Surgical repair of Crawford typeⅡ TAAA involves a wide range of treatment and is highly invasive, requiring ingenuity in terms of preventing complications such as spinal cord infarction. Hybrid repair including visceral artery debranching TEVAR may be an effective treatment modality for complex aortic lesions including TAAA, but requires careful follow-up including remote complications.
