Utilizing Perforator Propeller Flaps for Donor Site Closure: Harvesting Large Workhorse Flaps without Lingering Concerns.

Abstract

Background:  Primary closure of donor sites following large flap harvest may not be feasible. The use of perforator propeller flap (PPF) in this setting is gaining popularity, successfully resurfacing the wound and lessening potential donor-site morbidity. In this study, we aimed to review our experience and outcomes using PPFs in donor-site coverage throughout the body.

Methods:  A retrospective chart review was performed of all patients who underwent one or more PPFs surgery for donor site resurfacing between February 2009 and December 2021. Flap and defect characteristics were summarized. Postoperative complications and perioperative factors were analyzed.

Results:  Fifty-five patients underwent donor-site reconstruction using 68 PPFs. Of the 55 primary donor sites, 44 were covered with a single PPF, 9 with two PPFs, and 2 with three PPFs. One flap experienced complete necrosis and four flaps experienced distal flap necrosis, leading to an overall complication rate of 9.1%. No risk factors were found to be statistically significantly associated with the complication. All secondary PPF donor sites were closed primarily. During the average follow-up period of 15.1 months, none of the patients developed contour deformities or functional impairments.

Conclusion:  The PPF technique can be safely and effectively used for donor-site closure with minimal complications. It greatly frees surgeons to harvest a large workhorse flap for demanding soft tissue defect reconstruction.
