Endovascular stent-graft placement for nonaneurysmal infrarenal aortic rupture: a case report and review of the literature.

Penetrating atheromatous ulceration of the infrarenal aorta is a rare entity. There are few reported cases of this lesion, and most of the published data is in regards to the thoracic aorta. Spontaneous rupture of a nonaneurysmal noninfected atherosclerotic infrarenal aorta is a rare event. We report the eleventh case of this occurrence and present the first reported case of endovascular stent-graft placement in treating this entity. We review the literature regarding ulcerative disease of the aorta and specifically discuss the published data on spontaneous rupture of the nondilated, noninfected infrarenal aorta secondary to penetrating atheromatous ulceration.
