A Case of EVAR of a Dissecting Abdominal Aortic Aneurysm with the Contralateral Limb of the Stent Graft Implanted Using the False Lumen Route

Abstract

A localized abdominal aortic dissection complicated by an abdominal aortic aneurysm is a rare disease, and there are few reported cases. For communicating aortic dissection, it’s common to reduce the false lumen internal pressure by implanting stent grafts in the true lumen. However, in this case, the false lumen had enlarged in diameter, and the true lumen was narrowed. Judging from the disorder in the true lumen, there was no commercial stent graft fitting the blood vessel diameter of the true lumen. Therefore, as a method of revascularization, we chose to implant the stent graft in the false lumen, ensuring a sufficient landing zone in a portion with good vascular properties. The patient has had a favorable post-surgery course, and no complications such as graft limb occlusion have been observed.
