Vasculature of the Gallbladder, Posterior View

Description

Positioned in a posterior orientation, the gallbladder lies inferior to the visceral surface of the liver, with its fundus projecting anteroinferiorly and its neck tapering medially toward the cystic duct. Arterial inflow is represented by the cystic artery, most often a branch of the right hepatic artery, coursing posterolateral to the cystic duct and dividing into superficial and deep (hepatic) branches along the gallbladder wall. Venous outflow tracks back through cystic veins to the portal venous system, including small veins that pass directly into the liver parenchyma from the gallbladder bed. Small vessels cluster around the infundibulum (Hartmann pouch region). A posterior vascular map matters because this is where anatomic variation hides. During laparoscopic cholecystectomy, the cystic artery may run posterior to the cystic duct, arise from the gastroduodenal or left hepatic artery, or double back as a short, fragile trunk that bleeds briskly when avulsed. Injury is rarely just arterial, small posterior cystic veins and gallbladder bed veins can cause persistent oozing even after the cystic artery is clipped. This is the setup for a difficult Calot triangle. Ideal for surgical anatomy teaching in hepatobiliary modules, this view supports figures and operative atlases discussing the critical view of safety, cystic artery variants, and hemorrhage control during cholecystectomy. It also fits radiology or endoscopy publications when correlating cystic duct anatomy with biliary intervention planning and post cholecystectomy complications such as hemobilia.
