A Huge True Axillobrachial Aneurysm Following Arteriovenous Fistula Ligation

Özet

Aneurysmal degeneration of the upper limb arteries is a rare entity. We discuss the clinical characteristics, surgical options for a huge true axillobrachial artery aneurysm following arteriovenous fistula closure after renal transplantation. The underlying pathogenesis of the true axillobrachial artery aneurysm remains unclear. The current theory is that the adaptive arterial wall enlargement is secondary to the increased flow in the inflow artery. Immunosuppressive therapy and corticosteroids contribute to the aneurysmal formation. Surgical treatment including aneurysmal excision, bypass with autogenous or prosthetic grafts are the primary therapeutic options. We believe that this case will be inspiring and helpful to the cardiovascular surgeons during their daily practice.
