Introduction:
Arteriovenous fistula (AVF) aneurysms are common in long-term hemodialysis due to repeated cannulations and high flow states. While often managed conservatively, surgical intervention is mandatory when skin integrity is compromised. We report an ulcerated basilic vein aneurysm in a patient with a 16-year hemodialysis history.
Material and Method:
A 72-year-old female on hemodialysis for 16 years, presented with one month of redness over her left brachiobasilic AVF. Over three days, the site became painful and developed an ulcerated aneurysm. Physical examination revealed a palpable thrill. Under local anesthesia, a longitudinal incision was performed over the basilic vein. The aneurysmal sac, integrated with the skin, was isolated. Following proximal and distal vascular control, the aneurysmal sac and the affected skin were excised. A side clamp was applied to the basilic vein, which was repaired using continuous Prolene sutures, ensuring the vessel lumen was not narrowed.
Discussion/Conclusion:
Post-clamping, the thrill was restored and peripheral pulses remained palpable. The AVF remained functional. This case demonstrates that surgical revision via aneurysmectomy and venous wall reconstruction is effective for vascular preservation. By salvaging the existing fistula, we eliminated the risk of life-threatening rupture while maintaining the patient's vital dialysis access.
