Abstract:
Objective To investigate the clinical application value of contrast-enhanced ultrasound (CEUS) in hepatic artery thrombosis (HAT) after pediatric liver transplantation. Methods Clinical data of 126 pediatric recipients undergoing liver transplantation were retrospectively analyzed. The incidence of HAT after pediatric liver transplantation was summarized. Color Doppler ultrasound and CEUS manifestations of HAT were compared. Results According to color Doppler ultrasound, 17 cases were highly suspected with HAT. Nine cases were highly suspected with HAT by CEUS, who were subsequently confirmed by CT angiography (CTA) or surgery. CEUS manifestations of HAT showed that hepatic artery was not seen surrounding the portal vein during the arterial phase or even portal venous phase. Hepatocyte necrosis occurred in 4 patients with HAT, and no perfusion of intrahepatic contrast agent was observed on CEUS. Conclusions CEUS yields high clinical application value in the diagnosis of HAT after pediatric liver transplantation. It has significant advantages compared with traditional CTA, which could be widely applied in clinical practice.
