Distal splenorenal shunt in children.

The distal splenorenal end-to-side anastomosis (Warren shunt) decompresses esophageal varices while maintaining high portal hypertension and avoiding reduction of portal venous blood inflow to the liver. The Warren shunt was performed in seven consecutive patients with portal hypertension, including post-necrotic cirrhosis, portal thrombosis, and schistosomiasis, all with recurrent esophageal bleeding. Five shunts remained patent and two thrombosed. There was no mortality. If long-term follow-up evaluations indicate its effectiveness in preventing esophageal hemorrhage, the distal selective splenorenal shunt would be the more physiologic and safer procedure in children with portal hypertension.
