Systemic and hepatic hemodynamics wereprospectively studied in 11 patients with Manson'sschistosomiasis and portal hypertension, as well asalterations resulting from the use of propranolol. Itwas decided that patients whose portal pressure was reducedby 30% with the use of the drug would not undergosurgery and that treatment would consist of the chronicuse of propranolol, associated with sclerosis of esophageal varices. This objective was not metby any of the patients whose portal pressure wasmeasured and the study was interrupted. Results showthat patients with Manson's schistosomiasis and portal hypertension have hyperdynamic circulation,mild pulmonary hypertension, greatly increased splenicblood flow, and preservation of total hepatic bloodflow. Administration of propranolol correctshyperdynamic circulation, aggravates pulmonary hypertension,does not alter portal pressure and reduces the sectorialportal blood flows, especially of the azygos vein, withmaintenance of total hepatic blood flow. These data favor the hypothesis of portaloverflow in the physiopathology of portal hypertensionof schistosomiasis.
