Anatomical variations and preoperative imaging technique concerning the anterolateral thigh flap: guiding the surgeon

The anterolateral thigh flap (ALT-flap) has a widespread use throughout the body because of the many engineering options. The anterolateral thigh has a complex local vasculature which can be of importance for the surgical approach. In general, the flap receives its perfusion from branches of the lateral circumflex femoral artery (LCFA). The LCFA however has a large anatomic variance. CT-angiography can guide the surgeon in selection the must suitable site and aid in the surgical approach.status: publishe
