Hepatic Histology and Morphometric Measurements in Idiopathic Extrahepatic Portal Vein Thrombosis in Children, Correlated to Clinical Outcome of Meso-Rex Bypass.

Objective: The aim of this study was to correlate clinical, histologic, and morphometric features of the liver in children with extrahepatic portal vein thrombosis (EHPVT), with surgical outcome after Meso-Rex bypass (MRB).

Background: Idiopathic EHPVT, a significant cause of portal hypertension, is surgically corrected by MRB. Correlation of histologic and morphometric features of the liver with outcome has not been reported in children.
