Penetrating carotid artery traumas are rare yet fatal injuries with a high rate of mortality, and survivors may live with neurological sequelae. Of all the types of penetrating carotid artery traumas, the total transection of the common carotid artery (CCA) may be the most serious, can lead to death quickly, and has few reports of survivors. We described two cases of patients with complete CCA transections who survived without any neurological sequelae. The penetrating neck traumas of both patients were confirmed as complete CCA severance by CT and surgical exploration. Case 1 received the insertion of an interposition polytetrafluoroethylene graft to reconstruct the CCA, with postoperative ultrasound and CT angiography (CTA) verifying the total occlusion. Case 2 underwent nonoperative management under close observation and did not develop delayed active bleeding or neurological symptoms. Both patients recovered well, and no nervous system sequelae appeared during the follow-up period. A carotid artery injury cannot be ruled out in an asymptomatic penetrating neck injury. If CTA is feasible given the patient's hemodynamic condition, then it should be used as a routine examination to evaluate cervical vascular injury in patients with penetrating neck trauma. Management for hemodynamically stable carotid artery injuries remains controversial. These two cases of transverse carotid artery injury have caused us to further consider the principles of this kind of case management., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Yang, Liu, Sun, Mou, Jia, Zhang, Song, Li, Zhang and Song.)
