Clinical application study of lateral thigh perforator flap

Objective To probe the feasibility and therapeutic effect of the lateral thigh perforator flap for repairing soft tissue defects in extremity limbs. Methods Dissected six fresh Chinese adult lower limbs specimens which were injected with red latex via arterial cannula. Obseved the number, distribution,course, category of the flaps' perforators and measured their length of pedicle, external diameter on the specimens.Combinafing the results of the anatomy study,thirteen lateral thigh perforator flaps,whose size were 3.0 cm × 3.0 cm - 19.0 cm× 8.0 cm, were applyied to repair different defect, in which 1 was pedieled flap and 12 were free flaps.Two of them applied vessel anastomosis in series with anterlateral thigh perforator flap. The axis was from the fibulae capitulum to greater trochanter of femur. Results All 13 flaps surived com-pletely.In 3-6 months follow-up,all flaps were with thin and good appearance,and they were characterized by soft texture and good colour.No chimatlon and ulcer appeared in any flap.There were no effect of motor function in donor site because of muscle conglutination and scar contracture. There were plainness figure in donor site where skin- grafing was used, and only linearity scar remained where sewed directly. Conclusion The lateral thigh flap had provided with thin and pleasing appearance, soft texture and minor morbidity in donor site and correspondingly easy dissection. It was feasiblely to repair middling to little skin and soft tissue defect in extremity limbs as a free flap, and to repair skin and soft tissue defect in knee and popliteal space as a pedicel flap.It could apply vessel anastomosis in series with anterlateral thigh perforator flap for repairing large defect.

Transplantation of perforator flaps: Systematic review of 108 case series

Objective To explore the clinical outcome of perforator flaps for reconstruction of limb soft tissue defects. Methods In this case series, from 2007 July to 2009 May, 108 cases of perforator flap to reconstruct the defects of the extremities were performed, of these, 98 were free perforator flaps, 10 were pedicled flaps. The perforator flaps included deep inferior epigastric artery perforator flap, anterolateral thigh perforator flap, thoracodorsal artery perforator flap, lateral thigh perforator flap, posterior interosseous artery perforator flap, collateral radial artery perforator flap, medial sural artery perforator flap, posterior tibial artery perforator flap, deep circumflex iliac artery perforator flap and peroneal artery perforator flap. The maximum size of the perforator flap was 44 cmx 9 cm, the minimum size of the perforator flap was 4 em x 2 cm.The donor defect was closed directly. Results Venous congestion occurred in 5 flaps, in 1 case venous congestion was overcomed after released the dressing, 4 flaps requiring reexploration for venous insufficiency,2 had a successful outcome, the other 2 flaps failed . The other 103 flaps were successful. The wounds healed without any infection complications. The follow-up ranges from 6-24 months( 10 months on average). The flaps were of good appearance and not bulky; there were only linear scars on the donor sites, the cosmesis and function of the donor sites were satisfying. Conclusion The muscle, deep fascia and motor nerve are not contained in the flap, the advantages of this type of flap is reducing morbidity of the donor site and its reliable blood supply and suitable thickness for resurfacing, no secondary debuiking is necessary. The perforator flaps can be chosen as the first option to deal with superficial extremity wounds. Key words: Perforator flaps; Limbs; Transplantation; Reconstruction ; Mierosurgery

Combined Thigh Flap for Closure of Massive Trunk Defect

A massive trunk defect resulting from resection of recurrent sarcoma was reconstructed with a combined free flap incorporating medial, anterior, and lateral thigh tissues. This flap included the tensor fasciae latae, lateral thigh perforator, and rectus femoris, all based on the lateral femoral circumflex pedicle. A saphenous vein conduit enabled this flap to replace resected tissues at the lower thorax. Combining the three different commonly used thigh flaps on a single large pedicle enabled transfer of a 47.5 x 33.5-cm mega-flap.

The free gracilis perforator flap for autologous breast reconstruction

The free gracilis perforator flap is an alternative possibility for autologous breast reconstruction, if previous abdominal operations preclude this donor site, or if there is atypical distribution of fat tissue. The perforator flap is based on the main pedicle of the gracilis muscle. The muscle itself and its innervation can be completely preserved, if the angiosome of this vascular pedicle offers sufficient tissue. In skinny patients however it may be necessary to include the neighbouring angiosome of the second gracilis pedicle by means of the intramuscular anastomosis between both pedicles. In such a case a thin muscle strip with the joining vessel must be included in the flap. The bulk of the gracilis muscle and its motor nerve can, however, still be preserved. Breast reconstruction with this technique was successfully performed on six patients (two bilateral). It is a good alternative to a reconstruction with gluteal, or anteromedial, or lateral thigh perforator flaps.
