 | | The differential diagnosis of enlarged hepatic artery includes an occluded or interrupted portal vein, a surgical portosystemic shunt, reversal of flow in the portal vein, parenteral feedings in newborns, hereditary hemorrhagic telangiectasia, cirrhosis or hepatic diseases associated with alcohol, vascular hepatic tumors, and primary hepatic artery dissection. |
 | | The enlarged umbilical vein is usually solitary, originating in the left portal vein, which courses inferiorly through the falciform ligament and along the anterior abdominal wall to the umbilicus, seen on longitudinal or transverse scans. |
 | | The portal vein is punctured directly and replaced by a guidewire/catheter, and contrast material is injected into the splenic vein and/or the superior mesenteric vein, depending on the clinical setting. |
