"Non-compressible" torso hemorrhage (NCTH) is the leading cause of preventable battlefield death, requiring rapid surgical or radiological intervention, which essentially precluded close to point injury. UK Joint Theatre Trauma Registry (JTTR) analysis 2002-2012 showed 85.5% NCTH mortality. JTTR vascular injury data 2003-2008 revealed 100% mortality in named truncal vessel injuries.
