Humeral Exostosis Complicated by Pseudoaneurysm of the Brachial Artery: A Case Report

  • 1. Department of Peripheral Vascular Surgery, Hassan II University Hospital, Fez.

Description

Vascular complications of humeral exostoses are rare but potentially serious [1]. We report the case of a 60-year-old patient with no significant medical history, admitted for a painful, pulsatile mass of the left arm.
CT angiography revealed a pseudoaneurysm of the brachial artery secondary to an adjacent humeral exostosis.
The patient underwent excision of the exostosis, evacuation of the pseudoaneurysm, and repair of the arterial defect.
Postoperative recovery was uneventful. This case highlights the importance of early diagnosis and appropriate surgical management of vascular complications related to bone exostoses [2,3].
