Endovascular repair of a ruptured chronic type B aortic dissection.

Aneurysm formation is a common sequel of chronic type B aortic dissection. Ruptured false lumen aneurysms have traditionally been treated with open repair. These procedures are associated with high morbidity and mortality rates. We report the first successful endovascular repair of a ruptured chronic type B aortic dissection in a patient who had been turned down for elective surgery. The endovascular management of chronic dissection with rupture is difficult and may necessitate stenting of both entry and reentry points to induce false channel thrombosis. The long-term efficacy of this technique is unknown.
