Abstract: Objective　To explore the effect of arteriovenous bypass combined with nail extraction on replantation of amputated finger in Ishikawa II area of children.　Methods　From July 2013 to November 2018, 27 children with 29 severed fingers in Ishikawa II area without venous anastomosis conditions were replanted by arteriovenous bypass and nail extraction. Venous transplantation for venous repair was performed in 9 cases and arterial repair in 5 cases.　Results　All of 29 fingers were survived, but 6 fingers had venous drainage problem which survived through lateral incision. All cases were followed up for 5~18 months (average 10.2 months). The shape of fingertips was acceptable, the pulps were full, and the nails grew nearly flat in the last follow-up. Two of them had mild finger atrophy.  Conclusions　The combination of arteriovenous bypass and nail extraction has good clinical effect in the treatment of amputated finger in Ishikawa II area of children without venous anastomosis conditions, which is worthy of clinical promotion.
