ABSTRACT
A 77-year-old woman was referred to our hospital for treatment of a ruptured thoracoabdominal aortic aneurysm (TAAA) with a maximum diameter of 7cm. Considering her age and level of daily activity, the placement of an endovascular stent graft was performed as an emergency rescue procedure. For termination of the endoleak from the distal portion of the stent graft detected by CT the next day, another stent graft placement was added after establishment of blood supply to the superior mesenteric and celiac arteries by placing a Y-shaped graft from the abdominal aorta to each artery with success. The patient was discharged from our hospital 25days after surgery with disappearance of endoleak and good graft patency. A hybrid technique with grafting to abdominal branches, followed by placement of stent graft, can be an alternative treatment for such high-risk patients with ruptured TAAA.
