Variations in the Vascular Anatomy of Free Anterolateral thigh Flap and Strategy for Harvest

The anterolateral thigh (ALT) flap is a versatile soft tissue flap. It can be harvested as a pedicled, free fasciocutaneous or myocutaneous flap. Vascularized fascia can be included or the pedicle may be harvested as a flow-through flap. The anterolateral thigh flap is harvested based on the lateral descending branch of the lateral circumflex femoral artery (LCFA). Anatomical variations of descending branch (quadriceps artery) of lateral circumflex femoral artery and strategy that is followed in these variation in harvesting anterolateral thigh flap are described
