Implantable Continuous Doppler Monitoring Device for Detection of Hepatic Artery Thrombosis After Liver Transplantation

Early hepatic artery thrombosis (eHAT) after liver transplantation occurs in 3 of adults and 8 of children and often results in retransplantation. eHAT is initially asymptomatic and arterial patency is monitored with percutaneous Doppler ultrasound screening (pDUS). The aim of the study is to analyze the diagnostic accuracy of “continuous” Doppler registration (CONDOR) using an implantable miniature Doppler.
