Abstract Superior mesenteric portograms were performed on 30 patients with biliary atresia (BA) at the time of initial portoenterostomy in 20, and at the stoma closure operation in 10. A withered-branch-shaped irregularity of the intrahepatic portal vein (PV) and collateral vessels were seen in 2 of 11 patients with portal pressures (PP) of 200 to 300 mmH2O; in 1 of 2 patients with PPs of over 300 mmH2O at the initial operation; and in 3 jaundice-free patients with PPs of 285, 320, and 305 mmH2O, respectively, at the stoma closure operation. Collaterals were the only abnormalities seen in two additional jaundice-free patients with PPs of 370 and 183 mmH2O, respectively. No anatomic changes in the extrahepatic PV at the porta hepatis were found on the portograms of either group of patients. Thus, we conclude that portal dissection itself does not affect the PV structure anatomically, a finding which has important implications in determining whether or not portoenterostomy adversely affects potential liver transplantation.
