Microvascular myocutaneous flaps in the lumbosacral area using the iliac artery and vein as recipient vessels.

Lumbosacral tissue defects are usually closed with local flaps. Sometimes in large high-situated defects free microvascular flaps are used. However, finding a suitable recipient vessel for microvascular anastomosis in this region is difficult. In large soft-tissue defects high in the lumbar area, closure with a free flap using the iliac artery and vein as recipient vessels channelled from the pelvic cavity to the back through a drill canal in a bone presents an alternative option where other vessels are damaged by radiotherapy or infection. This has been used successfully in two cases.
