Renal blood flow before and after portosystemic shunt in children with portal hypertension.

Introduction: Variceal haemorrhage in children with extrahepatic portal hypertension is best controlled by an effective decompressive shunt, but long-term follow up of children who have had splenorenal shunt due to extrahepatic portal hypertension (EHPH) gave evidence for assuming the risk of renal venous hypertension (RVH).

Purpose: To study renal hemodynamic before and after portal decompression.

Methods: The results of 144 portosystemic shunt operations were followed from 2005 to 2013.
