Abstract | Penetrating atherosclerotic ulcer (PAU) is defined as an atherosclerotic lesion in which an ulceration occurs in the diseased aortic intima leading to disruption of the internal elastic lamina. It may cause a pseudoaneurysm formation or transmural aortic rupture. We describe a patient in whom a ruptured PAU in the distal aortic arch was treated successfully by a surgical endovascular stent graft. Through a median sternotomy and under deep hypothermic circulatory arrest, the aorta was transected between the left common carotid and subclavian arteries. A dacron prosthetic graft with self-expanding original Z type stents attached inside of the distal half was inserted through the aortotomy to exclude the PAU. By performing the procedure through a median sternotomy, we could eliminate dissection around the ruptured aortic wall. The stented graft was secured safely in the thoracic aorta to exclude the ruptured ulceration located distal to the left subclavian artery. PAU should be recognized widely as a distinct cardiovascular surgical problem which may lead to intramural hematoma with or without dissection or rupture. |
