Abstract
A method was developed for the quantitative measurement of blood flow through the porto-pulmonary anastomosis in portal hypertension. Among 12 patients with portal hypertension 2 patients showed 14.4% and 11.3% of the blood flow through the porto-pulmonary anastomosis, respectively. Other 3 patients showed near-normal values, and 7 patients normal values. There was no significant correlation between the calculated blood flow and the arterial oxygen saturation.
