title: Endovascular treatment of contained rupture of a superior mesenteric artery aneurysm resulting from neurofibromatosis type I.
abstract: A 31-year-old woman with neurofibromatosis type I (NF-I) came to our hospital with hypotension and abdominal pain. A computed tomography (CT) scan showed blood in the retroperitoneum and two saccular aneurysms in the superior mesenteric artery (SMA). The largest measured 2.5 cm in diameter. She was treated with placement of a covered stent in the SMA, and both aneurysms were excluded from the systemic circulation. Arterial aneurysms are rare in this disease, and rupture of an SMA aneurysm in this context had been reported only once. We report an unusual case of a contained rupture of an SMA aneurysm associated with NF-I, successfully treated with a covered stent.
