title: The use of temporary vascular shunts in military extremity wounds: a preliminary outcome analysis with 2-year follow-up.
abstract: BACKGROUND
  The use of temporary vascular shunts (TVS)s in the management of wartime extremity vascular injuries has received an increasing amount of attention. However, the overall impact of this adjunct remains incompletely defined. The objective of this study is to characterize outcomes of those patients who suffered wartime extremity vascular injuries managed with TVSs.
  
  
  METHODS
  This is a retrospective review of the Navy and Marine Corps Combat Trauma Registry examining peripheral vascular injuries treated during the military conflicts in the Middle East. Patient demographics, injury severity score, mechanism of injury, and vessels injured were recorded. Operative reports were reviewed for use of TVSs, type of definitive repair, the need for amputation, and survival.
  
  
  RESULTS
  Eighty patients were included. Forty-six (57%) had TVSs placed and 34 (43%) underwent repair at initial presentation. The mean injury severity score for the TVS group and the non-TVS groups were 15.0 +/- 5.05 and 12.9 +/- 10.18, respectively, (p = 0.229). There were a total of 13 amputations, 6 (13%) in the TVS group and 7 (21%) in the non-TVS group (p = 0.38). There was no difference in amputation rates between either group. There were no recorded mortalities in either group. Median patient follow-up was 24.5 months (range, 3-48 months).
  
  
  CONCLUSIONS
  This study demonstrates the importance and utility of TVSs in the management of wartime extremity vascular injury. When used to restore perfusion to an injured extremity, there seems to be no adverse effects or overall increase in limb loss rates and therefore a useful adjunct in the surgery for limb salvage.
