A Case of Difficulty in Extracting a Constraining System from an Excluder C3 Stent Graft System

Abstract

A 70-year-old woman was referred to our hospital because of an abdominal aortic aneurysm. She was on maintenance dialysis for chronic renal failure, had calcification of the aorta, and had undergone abdominal surgery, so we decided to perform stent grafting. Since the aorta was not bent at all, we decided to use an Excluder. After deployment of the proximal side of the main body, cannulation of the contralateral gate, and placement of the contralateral leg, we attempted to remove the constraining system, but it was difficult because the proximal side of the main body was constrained. The wire was replaced, the constraining system was manually removed while capturing the proximal side of the main body with a balloon, and the entire system was removed. The lock pin of the constraining system was bent in the removed device. So, it was considered that the wire had entered into the anchor of the constraining loop and the lock pin.
