Femoral artery based myocutaneous flap for hemipelvectomy closure: amputation after failed limb-sparing surgery and radiotherapy.

In this report, we have presented the first patient treated with a discontinuous myocutaneous flap for coverage of a hemipelvectomy combined with buttockectomy. This procedure allows circumferential excision of all tissues anterior and posterior to the hemipelvis. The circular defect that extends from the anus to anterior abdominal wall is covered with fresh tissue obtained from the anterior thigh just above the knee and supported on the superficial femoral artery. The major principles to be emphasized are the use of uninvolved tissues, as well as obtaining adequate tumor-free margins.
