[Results of spleno-renal anastomosis in the treatment of portal hypertension due to mansoni schistosomiasis. Apropos of a review of the literature].

1001 cases of spleno-renal shunts taken from 26 publications were selected after a literature review. The great majority of these were retrospective and had a very poor follow-up. The operative mortality levels were acceptable (4,5%) and the portal pressure decreased considerably. Nevertheless it has been shown that in 30,3% of the cases, thrombosis of the anastomosis developed. Recurrence of bleeding occurred in 16% of a population in which permeability of the anastomosis had not been controlled and it could be estimated that it goes up to 52% for the group with thrombosis of their anastomosis. Portal systemic encephalopathy varies with age, being 17% for people below 38,5% above 44 years of age.
