A Case of Late Open Conversion without Any Types of Endoleak after Emergent EVAR for Rupture

Abstract

A 67-year-old woman underwent emergent EVAR using Endurant II for ruptured abdominal aortic aneurysm. The postoperative course was uneventful, but CT scan 4 month later revealed a saccular protrusion of 25 mm in height on the anterior wall of the abdominal aortic aneurysm. Contrast-enhanced CT did not show any obvious endoleak, but we decided to perform prosthetic graft replacement by laparotomy. When the aneurysm was opened without clamping the aorta, a yellow fluid flowed out. Neither hematoma nor endoleak was observed in the aneurysm. The stent graft was resected as much as possible, and graft replacement was performed. The postoperative course was uneventful.
