Endovascular Stent-graft Repair for Infrarenal Aortic Pseudoaneurysm Caused by Penetrating Atherosclerotic Ulcer: Report of Two Cases.

摘要

Abstract Penetrating atherosclerotic ulcer (PAU) of the infrarenal aorta is rare and occurs when an atherosclerotic plaque ulcerates through the intima. PAU can be complicated by the development of intramural hematoma, adventitial pseudoaneurysm, and rupture. We report two cases that were treated by endovascular stent-graft placement and discuss the literature.
