Objetive To report the effect and clinical applications of using antegrade digital artery flaps from the same finger to repair digit injury and pulp loss. Methods From January 2009 to December 201 2.46 cases of the digit fingertip injury and finger pulp defect were treated with anterograde digital artery flaps transfer form the same finger,there were 25 cases of them which preserve nail bed.there were 24 cases of finger tip in-gury and 31 cases of pulp defect.The defect scopes were 0.5 cm ×1 .0 cm to 0.8 cm ×1 .0 cm the age ranged from 2 to 1 1 years,the average age was 5 .8 years. Results All flaps survived after operation,there was no vascular crisis.1 0 cases with nail bed and 1 0cases without nail bed which were followed up from 1 to 3 years. The flaps had good appearance and texture and sweat,here were just few string sign on the donor and receient sites.The nails of 1 6 cases which preserve nail bed grew normally without nail bed partial andnail deformity,4 cases of they have longitudinal ridge or nail stripes.Two point discrimination were normal.fine touch and func-tion of finger motion were obtained. Conclusion When the indication under control it is a better method for repair of finger tip defect and finger pulp loss by the digital neurovascular antegrade flaps from the same finger.%目的：总结小儿同指顺行指动脉神经蒂皮瓣修复指端（腹）缺损的临床应用及疗效。方法2009年1月至2012年12月我们对46例小儿指端（腹）缺损的患儿应用同指顺行指动脉神经蒂皮瓣进行修复，其中25例切取时保留甲床神经分支。46例中，指端缺损24例，指腹缺损22例，皮肤缺损面积0．5 cm ×1．0 cm～0．8 cm ×1．0 cm。年龄2～11岁，平均年龄5．8岁。结果皮瓣全部成活，无动静脉危象发生。选择保留和不保留甲床神经分支病例各10例，经1～3年随访，皮瓣外形饱满，色泽、出汗正常，供受区仅有线样瘢痕。16例甲床者指甲发育正常，无甲板分离及勾甲畸形，4例出现轻度甲纵脊或横纹。两点辨别觉正常，精细触觉恢复，手指无活动障碍。结论在严格掌握适应证的前提下，同指顺行指动脉神经蒂皮瓣是修复小儿指端（腹）缺损的良好方法。
