title: Change of hepatic arterial systolic/diastolic ratio predicts ischemic type biliary lesion after orthotropic liver transplantation.
abstract: BACKGROUND
  We conducted this prospective nested case-control study for the hepatic artery and portal vein hemodynamic changes after orthotopic liver transplantation.
  
  
  METHODS
  A total 128 cases of orthotropic liver transplantation were analyzed, including 25 cases of ischemic type biliary lesions (ITBL). The portal vein and hepatic artery flow velocities were detected by ultrasound on days 28, 42, and 84 after liver transplantation. In the GLM analysis of Lg(S/D), the P values of Group Effect, Time Effect, and Time×Group were 0.014, 0.376, and 0.008, respectively.
  
  
  CONCLUSIONS
  Our results show a relatively reduced hepatic artery S/D in ITBL, especially in extrahepatic ITBL.
