“Introduction Blunt carotid and vertebral artery injury (BCVI) is infrequent, but may have serious repercussions. The incidence of this type of injury is difficult to evaluate as many emergency room patients are neurologically asymptomatic or have symptoms attributed to cranial trauma or to other associated injuries. Previous studies estimated that BCVI injuries remain undiagnosed in two-thirds of patients [1, 2]. More recent statistics show an incidence of BCVI lesions in 0.24% to 0.33% of trauma patients with some symptoms of neurological impairment [3, 4]. Therefore, the high index of suspicion is fundamental to the diagnosis of these lesions in blunt cervical trauma. To our knowledge, this is the first study to examine the incidence of BCVI in Brazil. Given the low incidence of these traumas, their actual morbidity and mortality have not been clearly established in the literature.
