Surgical management of pseudoaneurysm complicating arteriovenous fistula for hemodialysis.

Objective: To report surgical experience in pseudoaneurysm (PA) repair of arteriovenous fistula (AVF) for renal hemodialysis.

Methods: Twenty patients undergoing PA repair of AVF for renal hemodialysis were treated in Central Hospital Conde S. Januario of Macao. Sixteen patients had PAs of AVF in upper extremities, 4 in lower extremities. All patients were treated with surgical therapy.

Results: All operations were finished without death. One patient suffered from acute thrombosis, recovered without any complication through instant thrombectomy. One patient with postoperative incision bleeding recovered after low molecular weight heparin was ceased. And one AVF could not be mature six weeks later, was recovered after ligation of branch vein. And one patient died due to recurrent cerebral infarction.

Conclusions: Surgical repair is the best choice for PA of AVF for renal hemodialysis.
