Angiography indicates patent ductus venosus. Continuous x-ray images were obtained over approximately 10 s as contrast was injected into the portal veins of Ah +/+ (A–F) and Ah −/− (G–L) mice. Angiograms are representative for five Ah +/+ and five Ah −/− mice. Serial radiographs are presented from left to right, showing the portal vein (PV), infrahepatic inferior vena cava (ihIVC), suprahepatic inferior vena cava (shIVC), ductus venosus (DV), and branching vessels (BV).
