Abstract: Objective To investigate the feasibility and application value of ultrasound in liver transplantation for patients with HIV infection complicated with viral hepatitis B cirrhosis. Methods The ultrasonographic features of 4 patients with HIV infection complicated with hepatitis B cirrhosis before and after liver transplantation were retrospectively analyzed. Ultrasound examination included hepatic arterial peak systolic velocity (PSV), Systolic acceleration time（SAT）, end-diastolic velocity (EDV), resistance index (RI), portal vein, hepatic venous flow velocity (PVV, HVV) and other hemodynamic indicators, maximum oblique diameter of the right hepatic lobe, perihepatic effusion, pleuroperitoneal effusion and CEUS. Results There were no contraindications for the related vessels and bile ducts in 4 cases diagnosed by preoperative ultrasonography.Early postoperative ultrasound showed no definite signs of rejection.The frequency spectrum of the intrahepatic artery in 1 patient showed small slow wave changes. Contrast-enhanced ultrasonography suggested active abdominal hemorrhage in 2 patients. All the above were confirmed by surgery, pathology or CTA. Conclusion Preoperative and postoperative ultrasound is of certain value in the evaluation of transplanted liver in patients with HIV infection complicated with hepatitis B cirrhosis, especially in the diagnosis of active bleeding by contrast-enhanced ultrasound.
