[Portal hypertension in schistosomiasis (author's transl)].

Pathological and clinical features of the portal hypertension in schistosomiasis are reminded. The value of the para-clinical investigations (immunology, endoscopy, angiography and hemodynamic controls) is discussed. Medical treatment is limited to parasiticidal action but an attempt to prevent the formation of granulomas by use of antilymphocytic serum has been reported. The surgical intervention is aimed at suppressing the splenomegaly and decreasing the portal hypertension. The indications of the various techniques are discussed (splenectomy, spleno-renal anastosomis associated with splenectomy, vascular porto-caval anastomosis, omentopexy, triple arterial ligation).
