| Abstract: | The practical relevance of volumetric blood flow in the hepatic artery during orthotopic liver transplantation was determined. From May 2009 to January 2011 25 patients underwent orthotopic liver transplantation. Volumetric blood flow in the hepatic artery is routinely measured using a Doppler flow meter during the operation. In 15 cases out of 25 (60%) the blood flow rate immediately after the formation of arterial anastomosis was 150 ml/min (190 +/- 40 ml/min) and increased to adequate with repeated measurements. In 2 cases out of 25 (8%) the blood flow rate reduced in repeated measurements, but by the end of operation the blood flow to the hepatic artery was at the satisfactory level. Blood flow less than 150ml/min immediately after the formation of arterial anastomosis was found in 8 cases out of 25 (32%). The cause of inadequate blood flow was identified and corrected. There were no cases of hepatic artery thrombosis at the early postoperative period. The routine use of intraoperative blood flow measurements allows timely determination of insufficient arterial blood supply of the transplant and elimination of its causes. |
