Type B aortic dissection and thoracoabdominal aneurysm formation after endoluminal stent repair of abdominal aortic aneurysm.

Endoluminal stent graft repair of abdominal and thoracic aortic aneurysms is being performed in increasing numbers. The long-term benefits of this technology remain to be seen. Reports have begun to appear regarding complications of stent graft application, such as renal failure, intestinal infarction, distal embolization, and rupture. Many of these complications have been associated with a fatal outcome. We describe a case of acute, retrograde, type B aortic dissection after application of an endoluminal stent graft for an asymptomatic infrarenal abdominal aortic aneurysm. An extent I thoracoabdominal aortic aneurysm subsequently developed and was successfully repaired. Aggressive evaluation of new back pain after such a procedure is warranted. Further analysis of the short-term complications and long-term outcome of this new technology is indicated before universal application can be recommended.
