11.%) and 43 patients with vertebral artery click here injuries (19.71%) [10]. Another study carried out by McKinney et al. performed angiography on 71 patients with risk factors

for cervical artery injuries over the course of 13 months; they identified 12 patients with carotid artery injuries (16.67%) and 12 patients with vertebral artery injuries (16.67%) [13]. In the current study, 12 out of the 100 patients with risk factors for carotid and vertebral artery injuries were diagnosed with vertebral injuries. The results of the current study are Selleckchem AZD5153 very similar to those of McKinney et al., with only a slightly smaller incidence of carotid and vertebral injury in the current study. McKinney et al. studied 24 patients with carotid and vertebral injuries and identified 10 patients with Degree I injuries, four patients with Degree II injuries, eight patients with Degree III injuries, two patients with Degree IV injuries, and no patients with Degree V injuries [13]. In the current study we identified seven patients with Degree I injuries, ten patients with Degree II injuries, no patients with Degree III injuries, Rabusertib cell line four patients with Degree IV injuries, one patient with Degree V injuries, and one patient with a fistula. Fabian et al. studied 67 patients with 87 carotid injuries, including 54 dissections, 11 pseudoaneurysms with dissections, 17 thromboses, four carotid-cavernous fistulas,

and one transection. The patients were treated in the following manner: the fistulas were embolized with a balloon, the transection was clamped, 47 of the patients were treated with heparin, eight patients were only observed, six patients Orotidine 5′-phosphate decarboxylase received aspirin, and one patient was submitted for surgery. In that study, the group of patients that received heparin showed greater improvement than those who did not receive heparin. The complications that occurred in patients who received heparin included: gastrointestinal hemorrhage, hemorrhage

of the hepatic artery, tracheal hemorrhage, two subdural hematomas that required surgery, and worsening of a ventricular hemorrhage. Subsequently, when 39 patients were reexamined, 62% showed normalization of the injury and 29% had developed a pseudoaneurysm [3]. Biffl et al. identified 114 patients with 157 injuries of the carotid arteries, and 79 patients with 97 vertebral artery injuries. In that study, 137 were Degree I injuries; 52 were Degree II injuries; 32 were Degree III injuries, 25 were Degree IV injuries; and eight were Degree V injuries. One week after trauma, 114 carotid injuries and 65 vertebral injuries were reevaluated with angiography, and 82% of the Degree IV injuries and 93% of the Degree III injuries showed no change. In contrast, 57% of the Degree I injuries and 8% of the Degree II injuries regressed to complete normality and treatment was discontinued.
