[Thoracic Endovascular Aortic Repair and Abdominal Aorta Replacement to Treat Stanford Type B Acute Aortic Dissection Extending through an Abdominal Aortic Aneurysm;Report of a Case].

A 69-year-old man developed sudden-onset chest and back pain and was brought to our hospital. Enhanced computed tomography (CT) revealed acute Stanford type B aortic dissection extending from the distal aortic arch to a 72 mm abdominal aortic aneurysm( AAA). The acute phase was managed by antihypertensive therapy, and the patient was followed up. Twenty days after the onset of aortic dissection, entry closure of aortic dissection by thoracic endovascular aortic repair and abdominal aorta replacement were performed simultaneously. Aorta remodeling was confirmed by postoperative CT, and the patient's postoperative course was uneventful. In the treatment of patients with acute aortic dissection and AAA, surgical intervention timing and strategy must be considered carefully.
