We describe a series of six patients who experienced severe retrograde amnesia (five cases) or cortical blindness (one case) during selective vertebral angiography. All angiograms were obtained with the same nonionic contrast medium. Analysis of the contrast batch demonstrated no abnormalities, but investigation of the angiographic suite revealed a faulty contrast warming cabinet resulting in injection of contrast material above body temperature. The warming cabinet was withdrawn, and the complication has not recurred. We believe that these symptoms reflect ischemia caused by vertebral arterial spasm.
我们描述了一系列六例患者,他们在选择性椎动脉血管造影期间出现了严重的逆行性遗忘(五例)或皮质盲(一例)。所有血管造影均使用相同的非离子型造影剂。对造影剂批次的分析未发现异常,但对血管造影室的调查发现一台造影剂加热柜存在故障,导致注入的造影剂高于体温。该加热柜已停用,并发症未再出现。我们认为这些症状反映了椎动脉痉挛引起的缺血。
