Isolated Axillary Artery Aneurysm Causing Peripheral Neuropathy of Upper Limb – A Case Report

Abstract

Axillary artery aneurysms are very rare and frequently occur as a result of penetrating or blunt chest trauma. They also occur iatrogenically or as a post obstructive lesion due to thoracic outlet syndrome or secondary to the chronic use of crutches. Atherosclerotic axillary aneurysms are very rare. When diagnosed, they must be treated without delay as they may invariably cause distal embolism or peripheral neuropathy threatening the affected limb. We describe a case of isolated true axillary artery aneurysm that had thrombosed and the patient presented with neuropathic symptoms. Duplex scan and CT angiogram were done to confirm the diagnosis which was successfully treated by axillary artery to proximal brachial artery interposition bypass with reversed saphenous vein graft.
