Application of color doppler ultrasound in monitoring liver graft dynamically and diagnosis and treatment of complications following liver transplantation

Objective: To investigate the value of color doppler ultrasound in monitoring the hemodynamics of liver graft dynamically and diagnosis and treatment of complications following liver transplantation. Methods: The color doppler ultrasound data of 107 cases of liver transplantation after operation in our center were retrospectively reviewed, then gathering the data and statistical analysis were made. Results: The velocity of the portal vein flow was increased but that of the hepatic artery was decreased as compared with those in control group at the early phase after the transplantation, and then these indexes returned to normal gradually. Among the 107 cases, hepatic artery thrombosis occurred in 2 cases, hepatic artery stenosis in 5 cases, portal vein thrombosis in 3 cases, recurrence of carcinoma in 7 cases, acute rejection in 18 cases, chronic rejection in 10 cases, pleural effusion in 105 cases and abdominal effusion in 65 cases, hepatic pseudoaneurysm in 1 case, pancreas leakage in 1 case, bile duct infection in 4 cases, bile duct stricture in 4 cases, bile leakage in 5 cases and calculus of common bile duct in 1 case. Conclusion: Color doppler ultrasound has an important clinical significance in monitoring the hemodynamics of liver graft and diagnosis and treatment of complications following liver transplantation.
