Three elderly men being evaluated for cerebrovascular disease developed acute confusional states following arteriography with approximately 50 ml of meglumine iothalamate. Two patients became stuporous. All recovered in several days, and no specific cause was found for the disorder. In the absence of other demonstrated abnormalities, we suggest that in each patient the encephalopathy may have been a toxic reaction to the contrast agent.
三名因脑血管疾病接受评估的老年男性，在使用约50毫升碘他拉葡胺进行动脉造影后出现急性意识模糊状态。两名患者陷入昏迷。所有患者均在数天内康复，且未发现该病症的具体病因。在没有其他已证实的异常情况下，我们认为每位患者的脑病可能是对造影剂的毒性反应。
