Right descending branch of lateral circumflex femoral artery (Ramus descendens arteriae circumflexae femoris lateralis)
Educational content only — not medical advice.
Anatomy
A major arterial branch running downwards deep along the anterior border of vastus lateralis accompanied by its motor nerve branch, descending to anastomose with the superior lateral genicular artery at the knee, providing a critical collateral pathway in superficial femoral artery occlusion.
Clinical notes
Forms the primary pedicle for the anterolateral thigh (ALT) free flap, one of the workhorse flaps in reconstructive microsurgery for extensive soft-tissue defects of the head, neck, and extremities.
