Extended wrap-around flap for reconstruction of the finger with recurrent arteriovenous malformation.

Treatment of arteriovenous malformations of the finger is difficult because complete resection of malformations by ligation or en bloc resecting methods is impossible. We used an extended wrap-around flap consisting of a combined wrap-around flap and a dorsalis pedis flap to reconstruct the soft-tissue defects following complete resection of a recurrent malformation in the index finger. This method has two advantages: no postoperative recurrence of the malformation is expected, and the affected finger can be preserved. However, it is indicated only for malformations with no invasion to the bone and localized in one finger.
