To assess the utility of a newly-developed combined system of ultrasonic sector and pulsed doppler flowmeter for the measurement of portal venous velocity, portal venous velocity measured by this system was compared with that measured by cineangiographic mapping of a Lipiodol droplet released in the portal vein through a thin catheter in 12 patients with esophageal varices. Portal venous velocity measured by the former method was about twice that by the latter method at various levels of measurements with a significant correlation (r=0.917). Thus, this doppler method is simple and noninvasive, and is particularly useful in the study of changes of portal hemodynamics.
