Anastomotic pseudoaneurysm complicating renal transplantation: treatment options.

INTRODUCTION

Anastomotic pseudoaneurysm following renal transplantation is uncommon. Indications for repair, treatment options and outcomes remain controversial.

REPORT

We present 6 renal transplant recipients with large anastomotic pseudoaneurysms. Five of the patients underwent open repair while one had a stent-grafting and delayed transplant nephrectomy for a ruptured pseudoaneurysm. A transplant nephrectomy was needed in all cases but one. Arterial reconstruction enabled limb salvage in all cases. One patient died of sepsis postoperatively. No patient presented late infection, failure of vascular reconstruction, nor pseudoaneurysm recurrence.

CONCLUSIONS

Surgical excision of anastomotic pseudoaneurysms results in high rates of allograft loss. Less invasive techniques have a place in selected cases.
