（足母）趾胫侧底动脉蒂足内侧缘静脉营养血管皮瓣的临床应用

Clinical application of venous nutrition flap pedicled by medial plantar artery of the hallux on the medical aspect of the foot

目的 报道（足母）趾胫侧底动脉蒂足内侧缘静脉营养血管皮瓣的临床应用效果.方法 根据跨趾胫侧底动脉与足内侧缘静脉营养血管间吻合关系,以第1跖趾关节近端（2.2±0.7） cm 处的（足母）趾胫侧底动脉穿出点为旋转点,以旋转点与内踝尖之间足内侧缘静脉走向为轴心线,设计（足母）趾胫侧底动脉蒂足内侧缘静脉营养血管皮瓣,转位修复（足母）趾皮肤软组织缺损.结果 临床应用共5例,皮瓣均成活,创面一期愈合,经1～12个月随访,皮瓣质地优良、色泽接近正常,外形美观.结论 （足母）趾胫侧底动脉蒂足内侧缘静脉营养血管皮瓣可转位修复跨趾皮肤软组织缺损.

Objective To introduce the clinical application of venous nutrition flap pedicled by medial plantar artery of the hallux on the medical aspect of the foot.Methods Based on the anastomoses between the medial plantar artery of the hallux and the nutritional vein,the flap was designed with the perforator of medial plantar artery adjacent to the first metatarsal bone as the rotation point.The flap axis was along the vein at the medial aspect of the foot between rotation point and medial malleolus.Results 5 cases were treated with primary healing and complete survival flaps.The patients were followed up for 1-12 months with good match of texture and color.Conclusions The venous nutrition flap pedicled by medial plantar artery of the hallux on the medical aspect of the foot can be transpositioned to repair the defect at forefoot.
