Right Hepatic Artery, Posterior View

Description

Posterior to the liver, the right hepatic artery courses toward the right lobe after branching from the proper hepatic artery, running in close apposition to the extrahepatic bile ducts at the porta hepatis. Its relationship to the portal vein is clear, with the arterial channel lying anterior to the portal venous trunk within the hepatoduodenal ligament, then dispersing into smaller intrahepatic branches that track along portal triads. Intrahepatic venous drainage converges toward central veins and larger hepatic veins that lie more posterior and superior, approaching the inferior vena cava. A pink, vertically oriented esophagus anchors the upper midline, posterior to the left lobe and cranial to the hilum. Posterior views of the right hepatic artery matter because the vessel is the commonest source of arterial injury during cholecystectomy and bile duct surgery, where it can be mistaken for the cystic artery or tether the common hepatic duct through anatomic variants. Surgeons also plan arterial inflow control for hepatectomy and transplant using the artery’s course relative to the portal vein and ducts, and interventionalists rely on this map when selecting branches for transarterial chemoembolization or managing hemobilia. Small details here change decisions. A replaced or accessory right hepatic artery from the superior mesenteric artery, for example, often takes a more posterior, rightward approach that can be missed without a clear posterior orientation. Use this illustration in hepatobiliary anatomy teaching (porta hepatis, portal triad organization, segmental inflow), operative atlases for laparoscopic cholecystectomy and hilar dissection, and radiology or IR materials that correlate CTA, angiography, and Doppler ultrasound findings with true spatial relationships. It also supports pathology and surgery texts discussing ischemic bile duct injury, biliary strictures, and hepatic artery thrombosis after transplant.
