Abstract

Chronic aortic dissection involving the neck of an abdominal aortic aneurysm is rare. The application of endovascular surgery in the treatment of an aneurysm with neck dissection has rarely been reported. We report two cases with abdominal aortic aneurysm and a history of chronic type B aortic dissection who could not tolerate conventional surgery. The dissection flap in the neck of the aneurysm was unhealthy and thus unsuitable as a landing zone. Extensor cuff is used to augment the true lumen of a dissecting proximal neck of abdominal aortic aneurysm before implantation of a bifurcated trunk device. The radial force of the extensor cuff augments the adhesion of the dissection flap to the aortic wall. The post-operative angiography showed no type I endoleak or migration of stent-graft. The 6-month follow-up was uneventful and no re-intervention was required. The use of an extensor cuff for pre-treatment of an abdominal aortic aneurysm with chronic dissection of the neck may provide an alternative treatment method for selected patients.
