[Changes in portal and hepatic blood flow in patients with chronic kidney failure as shown by Doppler ultrasonography].

Abstract

45 patients with chronic renal failure (CRF) were examined for blood flow in the portal vein and hepatic artery using impulse dopplerography. In the hepatic artery there was lowering of maximal systolic blood flow, end diastolic blood flow, elevated pulsative index and index of resistance. These changes appeared at early stages of CRF and progressed with its progression.
