[Ultrasound measurement of portal blood flow. Initial results in the study of hemopathies].
Portal blood volume was non invasively evaluated with pulsed Doppler ultrasound coupled with automatic, water path echotomography (U. I. Octoson). This measurement was successful in 18 from 24 normal volunteers, the portal flow values being 14.25+ or -4.5 ml/min/kg. The portal blood flow measurement was possible in 16 from 17 patients with hemopathy. Portal flow volume was greatly increased in 11 cases (more than 23 ml/min/kg), in connection with splenomegalia. It was moderately high in 3 cases, from whom 1 without splenomegalia and 1 splenectomised. Portal flow was normal in 1 case and was reduced in 1 case (with high splenic blood flow, in a patient with portal hypertension due to portal vein compression by adenopathy). Portal blood flow increase seems to be connected with splenomegalia. Manometric portal hypertension seems to be more clearly connected with hepatic invasion by hemopathy.
