Transient cortical blindness (TCB) is reported as a rare complication of coronary and cerebral angiography. Angiography of the vertebral arteries carries the highest incidence of causing TCB. The etiology of this phenomenon is unknown.
A 42-year-old woman underwent treatment for an enlarging pseudoaneurysm of her vertebral artery. The patient had a brief complex seizure during angiography. Following the procedure, she experienced TCB. During this time, an electroencephalogram (EEG) showed seizure activity. This case represents the first recorded instance of abnormal EEG during angiography-associated TCB.
The patient was immediately given intravenous lorazepam and phenytoin sodium. Her EEG returned to normal in the ensuing hours and subsequently her vision returned to normal.
We present the first reported case of abnormal EEG activity during angiography-associated TCB. We hypothesize that seizure activity is a possible underlying cause of angiography-induced TCB.
短暂性皮质盲（TCB）是冠状动脉和脑血管造影术的罕见并发症。椎动脉造影术导致 TCB 的发生率最高。这种现象的病因尚不清楚。
一名 42 岁女性因椎动脉假性动脉瘤增大接受治疗。患者在血管造影过程中出现短暂性复杂癫痫发作。术后，她出现 TCB。在此期间，脑电图（EEG）显示有癫痫活动。该病例代表了在与血管造影相关的 TCB 中首次记录到异常 EEG 的情况。
患者立即静脉注射劳拉西泮和苯妥英钠。她的 EEG 在接下来的几个小时内恢复正常，随后她的视力也恢复正常。
我们报告了首例与血管造影相关的 TCB 期间出现异常 EEG 活动的病例。我们假设癫痫活动是血管造影引起的 TCB 的一个可能潜在原因。
