A patient with bleeding esophageal varices underwent a distal splenorenal shunt during the sixth month of pregnancy. Although she demonstrated no functional or structural abnormality of the liver and no splenomegaly, her splenic vein pressure at operation was 32 cm H2O. The shunt reduced it to 13 cm H2O. Follow-up studies at nine months showed patency of the shunt, normal liver function, excellent hepatic perfusion by portal blood, and disappearance of varices. There has been no bleeding during a total follow-up period of three years.
