Application of latissimus dorsi flap and thoracodorsal artery perforator flap in different wounds / 中华整形外科杂志

Objective@#To explore the application and choice of latissimus dorsi musculocutaneous flap and thoracodorsal artery perforator flap in different wound repair.@*Methods@#From March 2012 to February 2018, 8 cases of different wounds were repaired with island latissimus dorsi myocutaneous flap pedicled with dorsal thoracic artery, free latissimus dorsi myocutaneous flap, or thoracodorsal artery perforator flap combined with scapular flap. The patients includes 4 cases of trauma, 2 cases of tumor and 2 cases of osteomyelitis. Among them, 5 cases received pedicled grafting, 2 cases had anastomotic vascular free grafting combined with antibiotic bone cement chain bead, 1 case had thoracodorsal artery perforator flap combined with scapular flap.@*Results@#All 9 flaps of 8 patients survived. The size of the flaps ranged from 22.0 cm×7.5 cm to 28.0 cm×21.0 cm. All the donor and recipient areas healed well. After 2 months to 2 years follow up, all flaps have good blood supply, and the limbs′ function was normal. The appearance of flaps were satisfactory, with fully treated osteomyelitis, and no recurrence of the tumor was observed.@*Conclusions@#According to wound characteristics, selective application of thoracodorsal artery perforator flap, pedicled or free latissimus dorsi myocutaneous flap is effective for the repair of muscle, skin and soft tissue defects, as well as osteomyelitis, after tumor resection.

Clinical application of thoracodorsal artery perforator flap in repair of serious scar contracture of opisthenar / 中国修复重建外科杂志

Objective: To investigate the feasibility and effectiveness of thoracodorsal artery perforator (TDAP) flap for repairing serious scar contracture of the opisthenar. Methods: Between March 2015 and June 2017, 7 cases of serious scar contracture of opisthenar were repaired with TDAP flaps. There were 5 males and 2 females with an average age of 31 years (range, 11-48 years). The time from injury to operation was 8-67 months, with an average of 42 months. After the relocation of the joint and release of the scar, the size of soft tissue defect ranged from 5 cm×4 cm to 10 cm×8 cm. The size of TDAP flap ranged from 5.5 cm×5.0 cm to 10.5 cm×9.0 cm. Results: All flaps survived completely with primary healing at both donor site and recipient site. The flaps of 3 patients were bulky and underwent second-stage skin flap thinning at 3 months after operation. All 7 patients were followed up 6-32 months, with an average of 15 months. The skin flaps were soft and elastic. According to the upper limb function evaluation system recommended by Chinese Society of Hand Surgery, sensory function was classified as S3+ in 2 cases, S3+ in 1 case, S2+ in 3 cases, and S11+ in 1 case. The hand function was excellent in 2 cases, good in 4 cases, and fair in 1 case. There was no significant effect on shoulder movement. Conclusion: The TDAP flap is an ideal method for serious scar contracture of opisthenar.

Reconstruction of the soft tissue defects of limbs using the free thoracodorsal artery perforator flaps / 中华显微外科杂志

Objective To investigate the clinical effects of reparing the complicated soft tissue defects of limbs with free thoracodorsal artery perforator (TDAP) flaps.Methods From April,2009 to March,2014,19 limbs (including 8 upper limbs and 11 lower limbs) soft tissue defects with bone and tendon exposure were repaired with free TDAP flaps in the secondary stage.There were 12 thoracodorsal artery perforator flaps,5 polyfoliate perforator flaps,1 chimeric muscle flap,and 1 chimeric muscle polyfoliate flap.The sizes of the flaps ranged from 5.0 cm×6.0cm-20.0 cm×l 1.0 cm.Seventeen wounds of the dornor site were closed directly,and the other 2 were closed with skin grafts.Results Sixteen flaps survived successfully.Two flaps had venous congestion and survived at last after taking the stitches out.One flap had partial necrosis and repaired by skin graft finally.The clinical results were satisfactory after 12-18 months following-up,and the scars of the dornor sites of all but 3 patients were not obvious.All the shoulder function were normal.Conclusion The TDAP flap has dependable blood supply,good texture,less dornor site morbility.The polyfoliate TDAP flap can be used for repairing irregular defect.The chimeric latissimus TDAP flap can be used for the function reconstruction.The free TDAP flap is suited for repairing soft tissue defects of the limbs.

Breast reconstruction with pedicled perforator flaps / 中国癌症杂志

Comparing with free perforator flap, pedicled flap is a relatively simpler and safer technique, with lesser donor site morbidity. In recent years, the application of pedicled perforator flaps has emerged as a new option for breast reconstruction. Those pedicled perforator flaps include thoracodorsal artery perforator flap, intercostal artery perforator flap (lateral intercostal artery perforator flap, anterior intercostal perforator flap) etc. Serratus anterior artery perforator flap, superior epigastric artery perforator flap, and lateral thoracic artery perforator flap can also be raised technically. To enhance surgical accuracy, it is necessary to evaluate the location and quality of perforator vessels preoperatively. Proper flap design is of more importance for pedicled flap when compared with it's free flap counterpart. Although free flap approach remains the golden standard in breast reconstruction when considering autologous tissue transplantation, pedicled perforator flap has the apparent merits of minimized surgical trauma, less time-consuming and less stress for reconstructive surgeons.

Soft Tissue Reconstruction of Children's Extremity with Perforator free Flap

Perforator free flap (PFF) is currently a major reconstructive option for soft tissue reconstruction in adults. Although PFFs have been used commonly, most reconstructive surgeons still hesitate to perform PFFs in children. The main cause of concern is the perceived high failure rate related to the small diameter of children's perforator vessels. We present 8 consecutive cases of successful transfer of thoracodorsal artery (TDA) & anterolateral thigh (ALT) perforator flap in children. Between 2003 and 2005, 8 children(4 to 13 years old) with soft tissue defects of the extremities were reconstructed with TDA & ALT PFFs. All flaps completely survived. There were no problems relating to vascular spasm or occlusion. Range of motion of reconstructed extremities were fully recovered. Among 8 patients, only 1 patient was performed an additional flap thinning procedure. 8 cases of TDA & ALT perforator flaps were successfully transferred in children. PFF is an excellent option in reconstruction of children as well as in adults because of its thinness, long pedicle length, least donor site morbidity and acceptable donor site scar.
