False aneurysms at both ends of a descending thoracic aortic stent-graft: complication after endovascular repair of a penetrating atherosclerotic ulcer.

摘要

PURPOSE: To report the formation of false aneurysms at both ends of a stent-graft implanted in the descending thoracic aorta to repair a penetrating atherosclerotic ulcer. CASE REPORT: A 66-year-old woman with a penetrating atherosclerotic ulcer was treated with a 34 x 70-mm homemade Gianturco-type stent covered with polytetrafluoroethylene graft. Four months later, she developed false aneurysms at both ends of the stent-graft. The patient refused further endovascular repairs, so the stent-graft was surgically removed and the aorta repaired. CONCLUSIONS: This case demonstrates an unusual complication that should be anticipated when a stent-graft is deployed in the acute phase of thoracic aortic ulcer or its variants.
