Abstract

Objective The aim was to evaluate the role of color Doppler ultrasonography (CDUS) in the evaluation of vascular complications detected in recipients of living donor liver transplantation (LDLT). Background Post-transplant-related vascular complications remain threat to the recipients' survival. A higher risk for vascular complications was found in LDLT recipients because of complex vascular reconstruction and slender vessels. CDUS acted as a first-modality imaging technique to detect vascular complications in the early and late follow-up period. Patients and methods A total of 60 liver transplant recipients who underwent LDLT in National Liver Institute Menoufia University were included. The study was done over a period of 25 months from January 2016 to January 2018. These recipients underwent serial color Doppler sonographic evaluation of hepatic arteries, portal vein, and hepatic veins after surgery. Patients with abnormal sonographic finding underwent subsequent angiography. Results The study was done by gray-scale, CDUS and included 47 patients of 60 recipients who showed suspicious vascular complications as follows: 26, 13, and eight patients had suspected arterial, portal, and hepatic venous complications, respectively. All these patients underwent conventional angiography. The sensitivity and specificity of CDUS in the evaluation of arterial, portal, and hepatic venous complications were 95, 87.5, and 87%, respectively, and 86, 91, and 96%, respectively, and for the latest complications was 87 and 96%, respectively. Conclusion CDUS was the preferred postoperative screening method; it was an initial recipient workup for post-LDLT. Providing a perfect evaluation of hepatic vasculature and assessment of early and lately presented vascular complications.
