Conventional ultrasonography highly contributes to a non invasive diagnosis of HS schistosomiasis (Cerri et al., 1984). The introduction of Dopple allowed new advances in the knowledge of the portal dinamics of this disease (Taylor et al., 1985; Moriyasu et al., 1986). The aim of this paper was to analize the hemodinamic behavior of the portal vessels, considering caliper, maximum flow speed, direction of flow and preferential disposition of the collateral vessels. Thirty two patients with schistosomiasis mansoni with confirmed hepatosplenic form (HSSM), were analyzed. Fourteen patients with the intestinal form, have been analyzed as a control group. The results demonstrated that the maximum speed of the portal vein in the two groups has not been significantly diferent. Nevertheless, the diameter of the PV in the hepatosplenic group has been larger. The splenic vein presented speed and caliper larger than the superior mesenteric vein. The hepatic artery has been detectly in only 40% of the cases. The hepatic veins presented normal caliper and spectral pattern. The duplex proved to be an useful technich complementar and non-invasive, in the study of the HSSM.
