The bipedicled iliac crest flap.

The use of the iliac crest flap based on the deep circumflex iliac artery and vein is well established in orofacial reconstruction. In cases where the deep circumflex iliac artery and vein are of inadequate size, or when large composite flaps are required, vascular augmentation can be achieved using the iliac branches of the iliolumbar artery and vein as an additional pedicle. Routine inclusion of this additional pedicle in iliac crest flaps creates extra safety with a low effort.
