摘      要：BACKGROUND Variations in the anatomy of hepatic veins are of interest to transplant surgeons,interventional radiologists,and other medical practitioners who treat liver *** drainage patterns of the right hepatic veins(RHVs)are particularly relevant to transplantation *** The aim was to identify variations of the patterns of venous drainage from the right side of the *** the best of our knowledge,there have been no reports on RHV variations in in a Caribbean *** Two radiologists independently reviewed 230 contrast-enhanced computed tomography scans performed in 1 year at a hepatobiliary referral *** outflow patterns were observed and RHV variants were described as:(1)Tributaries of the RHV;(2)Variations at the hepatocaval junction(HCJ);and(3)Accessory *** A total of 118 scans met the inclusion *** 39%of the scans found conventional anatomy of the main hepatic *** RHVs were present 49.2%and included a well-defined inferior RHV draining segment VI(45%)and a middle RHV(4%).At the HCJ,83 of the 118(70.3%)had a superior RHV that received no tributaries within 1 cm of the junction(Nakamura and Tsuzuki type I).In 35 individuals(29.7%)there was a short superior RHV with at least one variant *** to the Nakamura and Tsuzuki classification,there were 24 type II variants(20.3%),six type III variants(5.1%)and,five type IV variants(4.2%).CONCLUSION There was significant variation in RHV patterns in this population,each with important relevance to liver *** radiologists and hepatobiliary surgeons practicing in the Caribbean must be cognizant of these differences in order to minimize morbidity during invasive procedures.
