Successful Hybrid Treatment of Stent-Graft Migration Caused by Type B Aortic Dissection after Endovascular Aortic Aneurysm Repair: A Case Report

Herein, we report a rare case of type B aortic dissection that occurred after endovascular aortic aneurysm repair (EVAR). A 66-year-old man underwent successful EVAR for an abdominal aortic aneurysm (AAA). Computed tomography (CT) 2 years after EVAR showed a type B aortic dissection with stent-graft migration and AAA expansion. Juxtarenal aortic expansion precluded simple stent-graft placement. He underwent hepato-spleno-renal bypass followed by stent-graft placement just below the superior mesenteric artery. Postoperative CT showed no endoleaks. This case reconfirms the importance of regular follow-up after EVAR and illustrates the usefulness of a hybrid approach.
