In patients presenting with hard signs of arterial injury, immediate surgical revascularization is indicated, with no delay to the operating room. Hard signs of vascular injury include the absence of pulses, expanding or pulsatile hematomas, palpable thrills or audible bruits, or history of pulsating hemorrhage. In patients who do not present with hard arterial findings, measure ABI and API pressure indices because the presence of normal pulses does not rule out the presence of clinically significant vascular injury. ABI and API measurements less than 0.90 are shown to have a 95% sensitivity and 97% specificity for arterial injury of consequence.
