During hepatic resection, the Pringle maneuver controls bleeding by clamping the structures contained within which anatomical structure?

• A Free edge of the lesser omentum (hepatoduodenal ligament) ✓
• B Gastrohepatic ligament
• C Falciform ligament
• D Triangular ligament of the left lobe

Explanation

The Pringle maneuver achieves temporary inflow occlusion by compressing the portal triad, meaning the portal vein, proper hepatic artery, and common bile duct, all contained in the free edge of the lesser omentum, the hepatoduodenal ligament. This controls hepatic arterial and portal venous bleeding but does nothing for back-bleeding from hepatic veins, hence the addition of total vascular exclusion in some cases. Continuous clamping is generally limited to short intervals to limit ischemic injury.
