[Spontaneous rupture of a superior mesenteric artery: report of two cases]. / Rupture spontanée d'un anévrisme de l'artère mésentérique supérieure : à propos de deux cas.

Superior mesenteric artery aneurysms are rare. Diagnosis and treatment are a real challenge. We report two cases of this type of vascular anomaly revealed by spontaneous rupture. The diagnosis was made by abdominal computed tomography angiography and treatment consisted in aneurysmorraphy in one case and bowel resection with the distal aneurysm in the second.
