Origin

The descending branch arises as one of three terminal branches of the lateral circumflex femoral artery.

Course

The descending branch of the lateral circumflex femoral artery descends on the anterior aspect of the vastus lateralis muscle, alongside the femoral nerve branch that supplies this muscle.

Branches

There are no named branches, however, the descending branch of the lateral circumflex femoral artery anastomosis with the superior lateral genicular artery, and thus contributes to formation of the genicular anastomosis.

Supplied Structures

The descending branch of the lateral circumflex femoral artery contributes to both the arterial supply of the quadriceps muscles of the anterior thigh and to the genicular anastomosis of the knee joint.

Artery

When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
