Repair of Acute Type B Aortic Dissection Complicated by Aortic Rupture with Debranching Thoracic Endovascular Aortic Repair and Left Subclavian Artery Occlusion Using Amplatzer Vascular Plug II

Abstract

An 88-year-old man with severe chest pain and syncope was admitted to our hospital. Contrast-enhanced computed tomography (CT) revealed acute type B aortic dissection with rupture. Considering age and operative risk, we performed emergency thoracic aortic endovascular repair with two-debranching of the left common carotid and left subclavian arteries. To prevent type II endoleak, we used Amplatzer Vascular Plug (AVP) II for left subclavian artery embolization. Postoperative contrast-enhanced CT showed no type II endoleak and rupture site exclusion. As postoperative persistent blood flow to the primary entry or rupture site causes re-rupture, AVP II was crucial in preventing type II endoleak.
