The effect of the distal splenorenal shunt on hypersplenism.

Twenty-four patients with leukopenia and/or thrombocytopenia improved these deficiencies after distal splenorenal shunts. The average white blood cell count for 23 neutropenic patients increased by an average 1000 cells/cu.mm p less than .01. The average platelet count for 13 thrombocytopenic patients increased by more than 40,000, p less than .02. Analysis of the data showed that patients older than 50 years, with a history of alcoholic liver disease and sinusoidal hypertension greater than 15mm Hg were most likely to correct leukocyte and platelet defects after distal splenorenal shunts.
