Abstract

Among 68 liver transplant recipients, 190 hemodynamic studies were performed to evaluate the role of sepsis, anemia, acute graft rejection, and persistent portosystemic shunts. The hemodynamic outcome after orthotopic liver transplantation (OLT) in stable patients was also determined. Patients with sepsis showed a significant increase in cardiac index (5.1 +/- 0.9 vs. 3.4 +/- 0.7 L/min m2) and hepatic venous pressure gradient (6.3 +/- 2.9 vs. 3.3 +/- 2.1 mm Hg), compared with patients without sepsis. Cardiac index was higher in patients with, than in patients without, anemia (4.1 +/- 0.6 vs. 3.0 +/- 0.6 L/min m2). The hepatic venous pressure gradient was higher in patients with than in patients without acute graft rejection (5.1 +/- 2.9 vs. 2.6 +/- 1.2 mm Hg). Among patients with acute rejection, the hepatic venous pressure gradient was higher in patients with severe rejection than in those with moderate or mild rejection (7.2 +/- 3.3 vs. 4.6 +/- 2.4 and 2.8 +/- 0.9 mm Hg). In the postoperative period, in patients undergoing transplantation for acute liver failure, the hepatic blood flow was normal and significantly lower than in patients receiving transplant for cirrhosis (1.15 +/- 0.37 vs. 1.96 +/- 0.71 L/min). In patients undergoing transplantation for cirrhosis, cardiac index, azygos, and hepatic blood flows significantly decreased after 1 year compared with the first 6 postoperative months. Multivariate analysis showed that sepsis, anemia, and time after OLT were independent variables influencing cardiac index. Sepsis, time after OLT, and the existence of portosystemic shunts were independent variables influencing hepatic blood flow.(ABSTRACT TRUNCATED AT 250 WORDS)
