Partial descending thoracic aortic replacement for chronic Type B dissection

Abstract

Repair of chronic Type B aortic dissection can be technically challenging. Here we describe a technique for the partial replacement of the descending thoracic aorta that minimises operative risk and avoids full replacement of the thoraco-abdominal aorta. This approach can be considered when there is heterogeneous perfusion of abdominal viscera by the true and false lumens of the chronically dissected aorta.
