Pelvic reconstruction with pedicled thigh flaps: indications, surgical techniques, and postoperative imaging.

Abstract

This article will describe and illustrate the relevant anatomy and surgical techniques used in pelvic reconstruction using regional pedicled thigh flaps, which is often necessary in oncologic surgeries. Examples of normal postoperative imaging and common complications that can accompany pelvic reconstruction with anterolateral, gracilis myocutaneous, and posterior thigh fasciocutaneous flaps will be provided. Pelvic reconstruction using regional pedicled thigh flaps is often needed with extirpative oncologic surgeries to eliminate dead space, provide pelvic organ support, restore form and function, and introduce vascularized tissue to promote wound healing. Radiologists need to be aware of the normal postoperative appearance of these flaps so that the flaps are not mistaken for residual or recurrent disease and so that residual or recurrent disease can be identified and treated.
