A rare case of traumatic occlusion of the carotid artery at the neck caused by a dog bite is reported. A 10-year-old boy presented delayed onset of left hemiparesis after a dog-bite wound in the right neck. CT scan revealed a cerebral infarction in the right basal ganglia, and IV-DSA disclosed complete occlusion of the right internal carotid artery at the neck. The patient was treated conservatively and his left hemiparesis improved, but impaired visual acuity remained on the right side. Repeated IV-DSA 12 days later showed recanalization of the right internal carotid artery. The mechanisms of the traumatic occlusion of the internal carotid artery were discussed with reference to the literature.
本文报道了一例罕见的因狗咬伤导致颈部颈动脉创伤性闭塞的病例。一名10岁男孩在右颈部被狗咬伤后出现左半身轻瘫延迟发作。CT扫描显示右侧基底节区脑梗死，IV-DSA显示右侧颈内动脉在颈部完全闭塞。患者接受了保守治疗，其左半身轻瘫有所改善，但右侧视力仍受损。12天后重复IV-DSA显示右侧颈内动脉再通。并参考文献对颈内动脉创伤性闭塞的机制进行了讨论。
