Abstract:
Objective To analyze the hemodynamic changes with color Doppler flow imaging(CDFI) after liver transplantation. Methods One hundred fifty-six patients with transplanted livers were included. Hepatic morphology and parenehyma was investigated with B-mode ultrasound, and the patency of hepatic anastomosis was assessed with CDFI. Hemodynamic parameters were also measured. Results It showed increased parenchyma echogenicity during the early period after liver transplantation. Hepatic hemodynamies changed as follows: peak systolic velocity of portal vein was high in the first day after operation, and then it progressively decreased; the peak systolic velocity of hepatic artery was not changed during the follow-up period;the resistance index of hepatic artery was a little higher in the first day after liver transplantation, then it decreased ( P<0.05 ). Conclusions CDFI is valuable in evaluating hepatic hemodynamic changes after liver transplantation.
