Emergency endovascular treatment for ruptured type B dissection in the abdominal aorta

Despite successful endograft placement in the thoracic aorta, dissections remain problematic in the abdominal aorta. Herein, the authors describe two successful cases of endovascular treatment of ruptured abdominal aortic dissections. One patient, despite previously undergoing successful thoracic endograft placement, presented with a ruptured false channel and was treated by excluding major re-entries with a covered renal stent and stent-graft limb. A second patient, with a ruptured dissection superimposed on a preexisting abdominal aortic aneurysm, was treated with thoracic and abdominal stent-grafts. In both patients, progressive healing of the aorta occurred, with patients presenting no symptoms at an average follow-up of 20 months.
