ObjectivesTo evaluate the role of sonography in revealing and characterizing liver transplant complications based on gray scale and color Doppler, describe the normal Doppler findings, and discuss the significance of distinguishing normal transient changes in the spectral waveform from findings that may suggests ominous complications.MethodsWe carried out a retrospective cross-sectional study at Prince Sultan Military Medical City, Riyadh, Saudi Arabia. The medical records and imaging studies of a total of 122 candidates who underwent transplantation between January 2016 to February 2022 were reviewed.ResultsOur results showed that most patients were males with the most frequent age group being those between 54-71 years. Hepatitis B virus and hepatic cellular carcinoma were the most common indications for transplants. A total of 95 patients received a graft from a living related donor. Regarding complications, biliary issues (including leaks and ducts dilation) were the second most frequent complication after collections. Vascular complications represented 7.4% of all complications and was the leading cause of death in 4.8% of cases. Among all vascular issues encountered during liver transplant, portal vein thrombosis was the most predominant. In respect to Doppler findings, portal vein velocities and resistive index of hepatic artery had re-averaged within 7-10 post-operative days in most patients.ConclusionUltrasound plays crucial role in the post-operative management of compilations, facilitating early detection, which is substantial for the graft survival.Copyright: © Saudi Medical Journal.
