title: [Emergency surgery for coronary ostial occlusion and aortic root aneurysm associated with Takayasu's arteritis; report of a case].
abstract: We report a case of Takayasu's arteritis who underwent emergency surgery. A 39-year-old female presented with severe back pain. Electrocardiogram demonstrated complete atrio-ventricular (AV) block and acute inferior myocardial infarction. Coronary angiography revealed ostial occlusion of the right coronary artery. Aortography and contrast-enhanced computed tomography revealed dilated and bizarre-shaped aortic root. The remainder of the aorta and its branches appeared normal. She underwent emergency aortic root replacement with valved conduit. Coronary artery bypass grafting to right coronary artery( RCA) using saphenous vein graft was performed concomitantly. Histologic findings of the aortic root were compatible with Takayasu's arteritis. Postoperative angiography showed graft patency. Takayasu arteritis should be considered for differential diagnosis of acute myocardial infarction in young woman.
