Axillary artery aneurysm associated with Arteriovenous malformations of the upper extremity: A case report

INTRODUCTION AND IMPORTANCE: Axillary artery aneurysms are an uncommon upper extremity pathology. While trauma is the most common cause, degenerative aneurysms may occur in high-flow vascular conditions, such as upper extremity arteriovenous fistulas. Arteriovenous malformations (AVMs) are a rare cause. CASE PRESENTATION AND DISCUSSION: We herein describe a 41-year-old male with multiple congenital high-flow AVMs in the left upper extremity who presented with an asymptomatic axillary artery aneurysm. The aneurysm was successfully treated with open resection and revascularization using a reversed basilic vein interposition graft. CONCLUSION: Clinicians should be aware of the possibility of an axillary artery aneurysm in patients with upper extremity AVMs.
