Transjugular intrahepatic portosystemic shunt and liver transplantation.

ABSTRACT

Transjugular intrahepatic portosystemic stent shunting (TIPSS) appears to be an attractive, nonsurgical procedure to overcome complications of end-stage liver disease. During the period August 1992 to February 1995, 23 adults who had previously undergone TIPSS received liver transplants. These patients were compared to 36 cirrhotic patients, grafted during the same time period, in relation to the implantation technique, the intraoperative use of blood products, and the length of their hospital stay. These groups were comparable for previous right upper quadrant surgery, splanchnic vein modifications, and Child-Pugh classification. Liver transplantation was performed electively in all TIPSS patients. Ten patients (43.4%) presented with a significant shunt stenosis at a median follow-up time of 4.5 months (range 2.5 to 30 months). At transplantation 8 of the 23 TIPSS patients (34.8%) had specific TIPSS-related modifications i.e., extrahepatic portal vein aneurysm formation (n = 2), dislocation of the distal end of the stent into the inferior vena cava (n = 4) or into the main portal vein trunk (n = 1), bilioportal fistula (n = 1), and pronounced phlebitis of the inferior vena cava and hepatic veins due to redilation of shunt stenosis (n = 4). The intraoperative blood product requirement at transplantation was similar in the 23 TIPSS-patients and in the 36 cirrhotic patients who received transplants without the TIPSS procedure during the same time period [median 800 ml (range 0-20300 ml) vs median 620 ml (range 0-7600 ml), respectively]. There was also no difference between the two groups in length of hospital stay [median 18 days (range 0-34 days) vs median 19 days (range 0-66 days), respectively]. We conclude that TIPSS plays an important role in the management of life-threatening complications of end-stage liver disease arising in potential liver transplant candidates. TIPSS should be considered as a temporary, effective bridge to elective transplantation and not as a means to lower the blood product requirement at transplantation. Specific TIPSS-related modifications should be recognized early by the transplant surgeon in order to adapt the technique of graft implantation.
