PY - 2020 T2 - Tintinalli's Emergency Medicine: A Comprehensive Study Guide, 9e AB - Trauma to an extremity with associated vascular injury has a 5% rate of mortality, 5% rate of primary limb amputation, and 17% rate of delayed limb amputation.1 Penetrating trauma with early shock from proximal arterial hemorrhage is more likely to lead to mortality. Blunt distal extremity trauma with associated distal vascular injury is more commonly involved in early limb loss and amputations. Risk factors for delayed amputation include major soft tissue injury, compartment syndrome, ischemia of more than 6 hours, and associated fracture.2 Injuries involving the lower extremities are more common than injuries involving the upper extremities. The two most commonly injured blood vessels are the femoral and popliteal vessels.3 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/19 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=1167028832 ER -
