ABSTRACT
The causes of subclavian artery obstruction are arteriosclerosis, chest trauma, extrinsic compressive lesion of tumor or fibrosis, ateritis and coractation of aorta. Symptoms associated with subclavian artery obstruction can manifest dizziness, vertigo, ataxia, bilateral visual change because of vertebral-basilar artery insufficiency, or manifest fatigue, claudication, rest pain, digital necrosis because of arm ischemia. Treatment of subclavian artery occlusive lesion can be only medical treatment if patients was asymptomatic and a variety of surgical procedures-endarterectomy, carotid-subclavian bypass, subclavian- subclavian bypass, axillo-axillary bypass-can be recommended according to the state of surrounding vessel and general condition of patients. We experienced a case of subclavian artery obstruction in a 65 years-old male with severe claudication in left upper extremity and who had suffered from ischemic symptoms of left lower extremity. Patient was surgically treated by femoro-femoral bypass on occlusive lesion of the left lower extremity and carotid-subclavian transposition on left subclavian lesion. Postoperative result was excellent and claudication of left upper and lower extremities were completely relieved.
