Abstract:
Objective To study the anatomic basis and its clinical effects of the adjacent perforator fasciocutaneous flap in planta.Methods From October,2010 to December,2017,the work was on two fronts:① The blood supply of the flap was studied by the dissection of 5 adult lower limbs which were perfused with red emulsion.Under the magnifying glass,the source of blood supply to the pedicle perforator fasciocutaneous flap near the foot was observed,and the caliber of perforating vessels was measured by vernier caliper.② Methods based on the anatomic study,the adjacent perforator fasciocutaneous flap was designed to repair plantar defect.Eleven cases with defects in planta were treated with the flap including 5 malignant melanoma,5 refractory wound and 1 pigmented nevus.The size of defects ranged from 1.5 cm×2.0 cm to 4.0 cm ×5.0 cm with the size of the flaps ranging from 7.0 cm×3.0 cm to 13.0 cm×7.0 cm.Results Anatomical studies showed that the supply vessels of the fasciocutaneous flap near the perforator of the plantar space were plantar medial arteries.The external diameter was greater than or equal to the 0.5 mm perforating number of about 7,the average outer diameter was (0.85±0.19) mm.The medial plantar artery emits multiple branches along the running direction and forms anastomotic branches in the arch of the foot to ensure the blood supply of the flap.Eleven cases of perforator fasciocutaneous flaps survived,including 1 case of distal necrosis of small area and healed after change dressings.The follow-up results during 6-24 months showed that all patients were walking normally,with full texture and no localized dull pain.Conclusion On the basis of the extent of diseases,projected the adjacent perforator fasciocutaneous flap,the wear resistance and abrasive resistance are improved resulted from flaps with similar skin texture of defects.The donor site can be closed directly without skin graft.It is an simple and reliable method to repair medium and small-sized plantar defects.
