Sufficient wound closure of large soft tissue defects remains a challenge for reconstructive surgeons. We aimed to investigate whether combined perforator propeller flaps (PPFs) are suitable to expand reconstructive options. Patients undergoing PPF reconstruction surgery between 2008 and 2021 were screened and evaluated retrospectively. Of 86 identified patients, 69 patients received one perforator propeller flap, while 17 patients underwent combined PPF reconstruction with multiple flaps. We chose major complications as our primary outcome and defined those as complications that required additional surgery. Postoperatively, 27 patients (31.4%) suffered major complications. The propeller flap size, the type of intervention as well as the operation time were not associated with a higher risk of major complications. A defect size larger than 100 cm2, however, was identified as a significant risk factor for major complications among single PPFs but not among combined PPFs (OR: 2.82, 95% CI: 1.01−8.36; p = 0.05 vs. OR: 0.30, 95% CI: 0.02−3.37; p = 0.32). In conclusion, combined PPFs proved to be a reliable technique and should be preferred over single PPFs in the reconstruction of large soft tissue defects at the trunk and proximal lower extremity.

Objective To describe the characteristics of the perforator vessel in the peroneal artery of the lower leg and to explore the use of perforator pedicle propeller flaps to repair soft tissue defects in the lower leg, heel and foot. Methods This retrospective study enrolled patients with soft tissue defects of the distal lower leg, heel and foot who underwent surgery using peroneal perforator-based propeller flaps. The peroneal artery perforators were identified preoperatively by colour duplex Doppler ultrasound. The flap was designed based on the preoperatively-identified perforator location, with the posterior border of the fibula employed as an axis, and the perforator vessel as the pivot point of rotation. Patients were followed-up to determine the outcomes. Results The study analysed 36 patients (mean age, 39.7 years). The majority of the soft tissue defects were on the heel (20; 55.6%). The donor-site of the flap was closed in 11 patients by direct suturing and skin grafting was undertaken in 25 patients. Postoperative complications included venous congestion (nine patients), which was managed with delayed wound coverage and bleeding therapy. All wounds were eventually cured and the flaps were cosmetically acceptable. Conclusions The peroneal perforator pedicle propeller flap is an appropriate choice to repair soft tissue defects of the distal limbs.

Objective Reconstruction of soft tissue defects in the foot and ankle remains challenging. This study was performed to investigate the technical points and clinical effects of a double-pedicle propeller flap for repair of foot and ankle soft tissue defects. Methods We used five fresh calf specimens to investigate the anatomical and operative aspects of a double-pedicle propeller flap. Eighteen patients with soft tissue defects in the foot and ankle subsequently underwent defect repair with double-pedicle propeller flaps. Results The anatomical study showed that the peroneal artery perforators and the sural nerve bundle (two blood supply systems) provided the theoretical anatomical basis for the double-pedicle propeller flap. The relative positions of the peroneal artery perforators and the sural nerve bundle differ according to the peroneal artery perforating level. Flap rotation in different directions can reduce or prevent the pedicles from compressing each other. All flaps survived, and three flaps developed local epidermal necrosis at the proximal end; these flaps healed after 1 to 2 weeks of dressing changes. The other 15 patients healed well. Conclusions The double-pedicle propeller flap can enhance the blood supply and venous return in the “big paddle” region of the flap, reducing the distal necrosis rate.
