Freestyle propeller flaps from the lower abdomen: a valuable reconstructive option for proximal thigh defects.

Abstract

The concepts of freestyle flap design allows for flap creation from virtually every place in the body. Descriptions of named flaps based on their arterial origin are commonly described in the literature, allowing for predictable flap design. However, in certain cases, isolating a flap based on a Doppler signal and retrograde perforator dissection will allow for appropriate flap creation and wound coverage. We describe a 52-year-old female with a chronic open wound that failed wound care and local soft tissue rearrangement. This led to detection of a strong perforator signal in the lower lateral abdomen prompting the use of a freestyle propeller flap. The patient recovered without complication. Twelve-month follow-up demonstrated trunk and lower extremity mobility without impairment. We describe a successful and novel use of a rare, unnamed perforator from the lower, lateral abdomen by employing the freestyle propeller flap for coverage of a proximal thigh wound.
