title: Artery-only fingertip replantations using a controlled nailbed bleeding protocol.
abstract: OBJECTIVE
  We report our experience, treatment protocol, and 2-year follow-up results of 24 fingertip replantations treated using the artery-only technique without vein or nerve repair.
  
  
  METHODS
  We performed a retrospective review of 24 patients who had undergone fingertip replantation at the same center between 2005 and 2011. All patients in this study had complete fingertip amputation at or distal to the distal interphalangeal joint of the fingers or interphalangeal joint of the thumb. Patients with incomplete and complete amputations who had undergone vein and/or nerve repair along with artery repair were excluded. All patients received the same protocol including removal of the nail at the surgery and intravenous heparin 70 U/kg administered at the time of arterial anastomosis. After surgery, the nailbed was mechanically made to bleed with a sterile needle and mechanically scrubbed with a heparin-saline gauze. All patients received the same postoperative medical treatment protocol until physiological outflow was restored. Successful replantation was confirmed with clinical observation.
  
  
  RESULTS
  Twenty-one of the 24 fingertip replantations (88%) were successful. The mean length of hospital stay was 7 days (range, 4-9 d). Fifteen of 22 patients required blood transfusion. The average amount of blood transfusion was 1.2 U (range, 0-3 U).
  
  
  CONCLUSIONS
  This study shows that the described technique and protocol reconstructed circulation without vein anastomosis and with a high success rate. Furthermore, adequate sensory recovery without any nerve repair had occurred by the 2-year follow-up.
