Retrograde ascending Stanford B aortic dissection complicating a routine infrarenal endovascular aortic reconstruction.

Abstract

Retrograde ascending aortic dissections usually complicate endovascular reconstructions of Stanford B dissections. Although rare, with an incidence of 1.3% to 6.8%, they are catastrophic, with a high mortality rate of up to 42%. The exact mechanism is not known, but all indications point to a mechanical interaction between the tips of the proximal bare stent and a fragile aortic wall. Practically all reported cases involve dissections of the thoracic aorta. We report a patient with an asymptomatic retrograde ascending aortic dissection that originated at the level of a damaged suprarenal stent during capture tip retrieval during a routine endovascular aneurysm repair to treat an infrarenal aortic aneurysm.
