Natural/spontaneous shunts in non‐cirrhotic portal fibrosis

Large natural/spontaneous shunts on splenoportovenography were demonstrated in 10 of 93 patients with non-cirrhotic portal fibrosis. There was significantly less bleeding in patients with spontaneous shunt than in those having no shunt. Large oesophageal varices (grade III-IV) were seen more frequently in patients without spontaneous shunt.
