Atlanto-occipital dislocation (AOD) is a grave injury that is rarely survivable. Patients who do survive often have long-term sequelae resulting from the intracranial damage sustained during the traumatic event. The high impact needed to cause AOD is translated to the intracranial vessels, which can lead to vascular injury. Pseudoaneurysm is one of the possible outcomes of damage to the vessel wall. We present a case of basilar artery pseudoaneurysm diagnosed 5 months after a traumatic AOD who was treated with intracranial stent placement and coiling.
枕寰关节脱位(AOD)是一种严重损伤,很少能存活下来。存活的患者往往因创伤事件中遭受的颅内损伤而有长期后遗症。导致AOD所需的高冲击力会传导至颅内血管,从而导致血管损伤。假性动脉瘤是血管壁损伤可能产生的后果之一。我们报告一例创伤性AOD后5个月诊断为基底动脉假性动脉瘤的病例,该患者接受了颅内支架置入和弹簧圈栓塞治疗。
