Abstract
INTRODUCTION: The treatment for soft tissue sarcomas has evolved to include radiotherapy, wide local excision and plastic surgical reconstruction. Goals for the reconstruction of these irradiated defects are the introduction of non-irradiated healthy tissue, tension-free closure and obliteration of potential dead space. Although many defects once required free tissue transfer for reconstruction, greater knowledge of anatomical vascular pattern has led to the increasing use of propeller perforator flaps, islanded and transposed into the defect. Propeller flap outcomes for the reconstruction of irradiated skin defects have only been reported in case reports. We evaluated the use of propeller perforator flaps at St Vincent's Hospital Melbourne in a series of patients for the reconstruction of irradiated sarcoma defects.
METHODS: All patients who underwent sarcoma resection with plastic surgical reconstruction at St Vincent's Hospital from January 2009 to February 2017 were identified from unit audits and medical record data and compared depending on the type of reconstruction. Propeller perforator flaps were evaluated compared to other methods of reconstruction.
RESULTS: Thirty-nine cases involved single perforator propeller flaps for reconstruction. The frequency of propeller flap reconstruction has greatly increased from 3 in their first year of use in 2013 to 12 in 2015. Most propeller flaps were used to reconstruct thigh defects (43.6%) followed by shoulder defects (17.9%). Generally the defects were smaller (138.7 cm2) than free flaps (214.2 cm2), and the usual composition of the defect was skin and subcutaneous tissue only. Patients who underwent propeller flap reconstruction had a significantly short length of inpatient stay (p < 0.01), and there were no total failures.
CONCLUSION: Propeller perforator flaps are useful for the reconstruction of irradiated defects in sarcoma reconstruction surgery, particularly small- to moderate-sized fasciocutaneous defects. They offer less morbidity, faster recovery and better aesthetic results than free or standard pedicle flaps. The success of propeller flaps has changed the algorithm for how we approach towards the reconstruction of irradiated sarcoma defects to consider their use as the first reconstructive option for superficial sarcoma defects.
