A Case of Endovascular Aneurysm Repair for Non-anastomotic Pseudoaneurysm in Dacron Vascular Graft for Abdominal Aortic Aneurysm Which is Diagnosed with 4-dimentional Computed Tomography

Abstract

An 87-year old man with a history of graft replacement for abdominal aortic aneurysm over 20 years previously was admitted to our hospital with a diagnosis of non-anastomotic aneurysm of Dacron graft. 4-dimentional computed tomography (CT) revealed extravasation from the previously replaced Dacron graft. Endovascular aneurysm repair (EVAR) was performed with ENDURANT Aorto-uni iliac graft. Postoperative CT at 3 months revealed shrinkage of the aneurysm without extravasation. Non-anastomotic Pseudoaneurysm treated with EVAR was rare and 4-dimentional CT was effective for the diagnosis of this disease.
