Does a pulseless limb poorly predict an arterial injury in combat trauma?
Our results demonstrate that a pulseless limb is a poor predictor of arterial injury and should not be considered a hard sign of vascular injury in the combat population. Variables including a high ISS, anemia, acidosis, and need for resuscitation products, each a surrogate for injury severity, may contribute to the decreased accuracy of the physical examination in our troops. This may translate into unnecessary immediate exploration or other interventions in patients who present with more significant injuries from the battlefield. Future studies must continue to focus on improved algorithms for diagnostic accuracy of extremity vascular injuries in this population.
PVH, which is a histologic marker of relative placental insufficiency, is a common finding in idiopathic PTB.
