ACUTE THROMBOSIS OF SUBCLAVIAN ARTERY:A CASE REPORT

Abstract   INTRODUCTION: Subclavian artery thrombosis is a condition in which the blood flow through the vessel is suddenly obstructed. In fact, occlusion occurs in one of subclavian arteries, especially in the left subclavian artery.

Left subclavian angiography showed a large thrombus in the proximal part of her left subclavian artery, the other sites of artery were normal. She had an elbow amputation in Tehran later.   CONCLUSION: Therapeutic intervention is indicated in any symptomatic patient. Rapid diagnosis and treatment of thrombosis of subclavian artery prevent ischemia and gangrene of upper extremity. Subclavian artery thrombosis is uncommon cause of acute upper extremity ischemia, but should always regard to it.
