Hepatoduodenal Liver to duodenum Portal triad: proper hepatic Derivative of ventral mesentery
ligament artery, portal vein, common Pringle maneuver—ligament is
bile duct compressed manually or with
a vascular clamp in omental
foramen to control bleeding
from hepatic inflow source
Borders the omental foramen,
which connects the greater

May be cut during surgery to
access lesser sac
Part of lesser omentum
Gastrocolic ligament Greater curvature and Gastroepiploic arteries Derivative of dorsal mesentery
