We present the angiographic findings of 46 patients with biliary atresia (BA). There were 25 males and 21 females, with a mean age of 22.5 months (range - 1.5 to 141 months). Hepatic and mesenteric angiography were obtained as part of a liver transplantation work-up or as part of the treatment of clinical events. All patients had a histological diagnosis of BA. The portal vein was patent in 43 patients, with a mean size of 4.1 mm, using the arterial catheter as comparison. Portal hepatopetal flow was observed in 20 patient and hepatofugal flow was observed in 21 patients. Presence of gastroesophageal varices was observed in 41 patients. The hepatic artery was enlarged in all patients. In all 46 patients studied, the intrahepatic peripheral hepatic artery branches presented with irregularities in contour, including encasement, strictures, dilatation and angulation, and images suggestive of peripheral occlusion. Angiographic vascular "tuft-like" blush surrounding the irregular or occluded peripheral arterial segments was observed in 40 patients. The injection of Microfil in one case showed a marked vascular proliferation within the portal tract, apparently derived from arterial and portal connections, filling the entire portal space. We conclude that the presence of angiographically demonstrable perivascular arterial tufts in the periphery of the hepatic arterial circulation is a common finding in cases of BA, and may be a characteristic diagnostic angiographic finding.
