title: Use of a Temporary Shunt as a Salvage Technique for Distal Extremity Amputations Requiring Repair by Vessel Grafting during Critical Ischemia.
abstract: BACKGROUND
  Although the use of temporary shunts in proximal extremity amputations has been reported, no study has described the use of temporary shunts in distal extremity amputations that require vein grafting. Moreover, the total volume of blood loss when temporary shunts are used has not been reported. The aim of this study was to investigate the applicability of a temporary shunt for distal extremity amputations requiring repair by vessel grafting with an ischemia time of >6 hours. This study also aimed to determine the total volume of blood loss when temporary shunts were used.
  
  
  METHODS
  Patients who underwent distal major extremity replantation and/or revascularization with a vessel graft and who experienced ischemia for 6-8 hours between 2013 and 2014 were included in the study. A 6-Fr suction catheter was cut to 5 cm in length after the infusion of heparin, and secured with a 5-0 silk suture between the distal and the proximal ends of the artery. While bleeding continued, the bones were shortened and fixed. After the complete restoration of circulation, the arterial shunt created using the catheter was also repaired with a vein graft.
  
  
  RESULTS
  Six patients were included in this study. The mean duration of ischemia was 7.25 hours. The mean duration of suction catheter use during limb revascularization was 7 minutes. The mean transfusion volume was 7.5 units. No losses of the extremity were observed.
  
  
  CONCLUSIONS
  This procedure should be considered in distal extremity amputations requiring repair by vessel grafting during critical ischemia.
