Comparative analysis of pulsed doppler ultrasonography of portal vein vs indirect portography

Abstract

There are some limitation of interpretation in indirect portography via superior mesenteric antery. In otherto supplement and predict indirect portography, we compared indirect portographic findings with pulsed dopplerflowmetry in 38 hepatobiliary patients, and the results were as follow: 1. In cases of normal main portalvein(MPV) filling. Pulsed Doppler always showed antegrade, continous parabolic wave form and cases of abnormal MPVfilling, showed unusal wave form and flow direction. 2. In normal filling cases of proximal right portal vein,Pulsed doppler almost showed normal continous parabolic wave form but in normal filling cases of proximal leftportal vein, occasionally showed undulating wave form. 3. In each side proximal portal vein abnormal filling case,we could observe abnormal doppler wave form and could obtain additional information using doppler wave form. 4.Mean portal flow velocity was significantly increased in higher portography grade(p=0.01) and Congestion index wassignificantly decreased in higher portography grade(p=0.01) 5. We concluded that doppler ultrasonography couldsupplement incomplete indirect portography and predict its peripheral filling grade.
