The vascular lacuna (Latin: lacuna vasorum (retroinguinalis)) is the medial compartment beneath the inguinal ligament.^[1] It is separated from the lateral muscular lacuna by the iliopectineal arch.^[1][2] It gives passage to the femoral vessels,^[1] lymph vessels and lymph nodes.

The lacunar ligament can be a site of entrapment for femoral hernias.^[2]

Anatomy[edit]

Its boundaries are the iliopectineal arch, the inguinal ligament, the lacunar ligament, and the superior border of the pubis.

Contents[edit]

• Cloquet's node;
