Brachial aneurysm caused by a long-term axillary crutch - A case and literature review

Abstract

Brachial aneurysms are a rare disease, accounting for 0.5% of peripheral aneurysms. Using a long-term axillary crutch may be associated with arterial injury and induce upper extremity aneurysm formation. A 67-year-old woman had a history of using a long-term underarm crutch due to polio disease. Physical examination revealed edema of the left upper limb, pulseless of the brachial artery, and disappearance of distal radial pulse. The imaging examination revealed a brachial arterial aneurysm in the left upper limb, along with thrombosis. The aneurysm and mural thrombus were excised. The great saphenous vein graft was inserted to reconstruct occluded artery blood supply; the left brachial and radial arteries pulsed well after operation. This case report suggests that long-term use of axillary support for patients should be done with caution. Regular follow-up of upper extremity vascular morphology should be done. Timely anticoagulant therapy to prevent thrombosis and surgical resection of aneurysms are effective strategies for resolving complications.
