Reconstruction of radiation‐induced ulcers with free flaps using the perforating vessel as a recipient vessel

Abstract

Free flaps can be options for coverage of radiation ulcers. However, due to radiation damage, it may be hard to find and dissect a reliable recipient vessel for microsurgical anastomosis. When the radiation fields are targeted for deep tissues, superficial tissues may be less affected by radiation. Therefore, damage to perforator vessels near the skin may be lesser than that to the major vessels in deeper structures. We would like to introduce our experiences of using these less injured perforating vessels within or near the wound as recipient vessels for free flap coverage.
