Objective : to investigate the effect of pumpless portosystemic bypass in clinical piggyback liver transplantation. methods : after catheterized inferior mesenteric vein, the silastic catheter ( filled with heparin saline ) was connected with the catheterized tube of internal jugular vein or subclavian vein in four piggyback liver transplantation patients. the channel was opened after the portal vein was occluded. the portal vein blood poured into the superior vena cava through the pumpless channel. the changes of mesenteric congestion, portal vein pressure, blood pressure and pulse were observed. results : during the occlusion of portal vein, the portal vein pressure was increased greatly, the intestine was congested and swelled obviously and the blood pressure and pulse fluctuated gently. after the pumpless bypass opened, intestinal congestion and swell were abated markedly, the portal pressure, blood pressure and pulse gradually returned to normal range. conclusions : pumpless portosystemic bypass shows a great effect on clinical piggyback liver transplantation. it is a feasible and economical method
