Use of bovine mesenteric vein in rescue vascular access surgery.
We describe a technique for rescue surgery of autologous arterovenous fistula (AVF), using bovine mesenteric vein (BMV), which may be used in patients with autologous AVF malfunction caused by steno-occlusion on the arterial side or by fibrosis of the first portion of the vein. To preserve the autologous AVF, we replaced the diseased portion of the artery, or the first centimeters of the vein, by a segment of BMV, with the aim of saving the patency and functionality of the access. We used this technique in 16 cases. All patients underwent hemodialysis treatment immediately after the procedure. Infection or aneurismal dilatation of the graft in implanted BMV was never observed.
