Six patients suffered from cortical blindness following vertebral artery angiography. A connection of the incident with the technical procedure or a particularly great amount of applied contrast material, could not be seen. Vasospasm, stasis of contrast material in the arteria calcarina and a toxic lesion seem possible explanations, because the cortical blindness was fully reversible in all cases within some hours or days. Signs for an arterial embolisation did not exist, a finding, which is consistent with the literature.
6例患者在椎动脉血管造影后出现皮质盲。未发现该事件与技术操作或所用造影剂剂量特别大之间存在关联。血管痉挛、造影剂在距状动脉内淤滞以及毒性损伤似乎是可能的解释，因为所有病例中的皮质盲在数小时或数天内均可完全恢复。不存在动脉栓塞的迹象，这一发现与文献一致。
