Takayasu's Arteritis-associated Superior Mesenteric Artery Aneurysm Treated by Stent-graft Implantation via the Common Carotid Artery

Introduction Complications of Takayasu's arteritis are usually ischemia of certain organs caused by progressive arterial narrowing, while dilative lesions or formation of aneurysms are relatively uncommon. Report A 43-year-old man with the chief compliant of abdominal discomfort underwent an enhanced computed tomography scan which showed a 30 mm × 23 mm superior mesenteric artery aneurysm. Because of the acute downward angulation of the superior mesenteric artery and inappropriateness for larger sheath placement brachial arteries, the aneurysm was excluded with a stent-graft via the common carotid artery approach. Discussion Stent-graft implantation through the common carotid artery is a feasible approach for the endovascular treatment of superior mesenteric artery aneurysms when unfavorable anatomic limits exist.
