ABSTRACT
Objective To investigate the methods and results of lateral leg propeller pedicled flaps based on multi-perforators for coverage of soft-tissue defects on the foot and ankle.Methods From May,2012 to June,2013,8 patients with soft-tissue defects were treated,including 5 cases by trauma,2 cases by chronic unlcers,1 case by infection on the foot and ankle with exposed osseous and tendinous.Lateral leg propeller pedicled flaps based on multi-perforators were elevated and rotated with the angle from 150° to 180° for coverage of soft-tissue de-fects.Flap size ranged from 15.0 cm × 7.0 cm to 23.0 cm × 9.0 cm.Skin graft was applied to cover the donor sites.After the operation,the blood supplies of flaps were observed severely over 10 days.Questionnaire of the flap aesthetic satisfactory and AOFAS evaluation were performed in 7 patients during fellowed-up periods.Results Seven flaps were all survived well,1 flap had partial marginal skin necrosis on the distal,which was managed with surgical debridement,and wound healed in 1 month.Seven patients had a mean of 10.7 months' fellowed-up periods.The flaps had like-like appearance,good contour,and high aesthetic satisfactor (100％).The mean AOFAS score was 90.5.Conclusion Lateral leg propeller pedicled flaps based on multi-perforators can supply the blood of the larger volume of tissue,which can be safely sustained to repair distal and larger defects on the foot and ankle.
ABSTRACT
Introduction: propeller flaps are local pedicle flaps, based on a perforator vessel, which acts as the pivot point for the skin island that can be rotated up to 180°. These flaps can be performed wherever a perforator vessel of adequate size is encountered, expanding the reconstructive options for lower limb defects. Clinical case: we present a case of reconstruction of soft-tissue defect of the leg using a peroneal artery propeller perforator flap. A review of the main advantages of this technique for reconstruction of lower limb defects is also presented.
Introducción: el colgajo en hélice (propellerflap) corresponde a un tipo de colgajo local pediculado, basado en vasos perforantes, que actúan como punto pivote sobre el cual se rota la isla cutánea hasta en 180°. Este tipo de colgajo puede ser efectuado en cualquier sitio donde exista un vaso perforante de calibre adecuado, ampliando las alternativas de cobertura para defectos de extremidad inferior. Caso clínico: presentamos un caso de cobertura de defecto de partes blandas secundario a aplastamiento de tobillo, utilizando un colgajo en hélice basado en perforante de arteria peronea. Se discuten las principales consideraciones respecto al uso de esta técnica en reconstrucción de extremidad inferior.
