Preservation of renal perfusion and postoperative renal function by side-to-side cavo-caval anastomosis in liver transplant recipients.
Postoperative renal failure is common after liver transplantation (LT). The aim of this study was to investigate peroperative renal perfusion and postoperative renal function in 12 patients who underwent LT with side-to-side cavo-caval anastomosis (SSCCA). Three phases were considered during the procedure: hepatectomy, the anhepatic phase, and the postreperfusion phase (phases 1, 2, and 3, respectively). Mean arterial pressure, IVC pressure, and renal perfusion pressure were significantly higher during phase 2 than during phases 1 and 3. Cardiac index and pulmonary capillary wedge pressure did not differ significantly during the three phases. Creatinine clearance did not significantly decrease postoperatively. We conclude that SSCCA is associated with both the preservation of renal perfusion pressure during the entire procedure and the preservation of postoperative creatinine clearance. It is, moreover, a technique that results in a low rate of postoperative renal failure after LT.
