Extremity vascular firearm injury(EVFI)which occurs in large quantities during wartime and is dispersed in peacetime,can result in acute hemorrhagic shock and compartment syndrome,thus seriously endangering the patients'life.Compared with vascular trauma,vascular firearm injury not only damages the arteries easily,but also has a more severe damage and a poor prognosis.At present,most of relevant reports on the clinical diagnosis and treatment of EVFI in China are based on the treatment experience in Vietnam's self-defense counterattack and lack subsequent technology,data and wartime echelon treatment.To this end,the authors discussed the epidemiological characteristics,diagnosis and treatment of EVFI by integrating the literature published since the Afghanistan and Iraq War,aiming to provide reference for the diagnosis and treatment of EVFI in China.
