Description

Axillary artery aneurysm and thromboembolism from the aneurysm is rare. The patient was a 47-year-old man and his chief complaint was sudden numbness of his right forearm during exercise. Contrast-enhanced computed tomography demonstrated a 35×33×50 mm fusiform aneurysm of the right axillary artery with mural thrombus. Right brachial artery was occluded. Because of the risk of re-thromboembolism and rupture, elective surgery was performed. Using the deltoid-pectoral approach, replacement of the aneurysm with an ePTFE graft was performed. Pathological examination revealed focal disappearance of medial smooth muscle cells without atherosclerotic change. His postoperative course was uneventful.
