Cystic Artery, Anterior View

Description

Arising most often from the right hepatic artery within the hepatocystic triangle (Calot triangle), the cystic artery courses laterally and inferiorly toward the neck of the gallbladder, where it typically divides into superficial and deep branches along the peritoneal surfaces. An anterior perspective places the cystic artery superficial to the cystic duct and adjacent to the inferior surface of the liver, with the common hepatic duct running medial and the gallbladder fundus positioned inferiorly. Small accompanying veins and lymphatics may parallel the arterial path toward the cystic node (of Lund) near the cystic duct. Short vessel. Big consequences. Surgical anatomy drives the value of this view. During laparoscopic cholecystectomy, the cystic artery is commonly the structure clipped after establishing the critical view of safety, and bleeding from an early branch, a short cystic artery, or a posteriorly coursing vessel remains a frequent cause of poor visualization and conversion. Variant patterns matter: a cystic artery arising from the left hepatic, gastroduodenal, or superior mesenteric artery, or a double cystic artery, can place a sizable branch outside the expected confines of Calot triangle and increase the risk of bile duct injury when dissection strays medially. Use this illustration in hepatobiliary anatomy teaching, operative technique chapters on cholecystectomy, and patient safety materials focused on avoiding common bile duct misidentification and controlling cystic artery hemorrhage; it also pairs well with angiographic or intraoperative photograph comparisons when discussing vascular variants.
