Transient cortical blindness is a known complication of iodinated contrast administration and is believed to reflect osmotic injury or autoregulatory dysfunction of the posterior circulation. Here, we report 2 cases of postangiography transient cortical , a rare clinical analog to transient cortical blindness that affects the anterior circulation. The symptoms, timeline, and imaging findings of transient cortical weakness are distinct from more common post-procedural complications such as acute ischemic stroke or transient ischemic attack.
短暂性皮质盲是碘造影剂给药已知的并发症，被认为反映了后循环的渗透性损伤或自动调节功能障碍。在此，我们报告2例血管造影术后短暂性皮质病变，这是一种影响前循环的罕见临床类似短暂性皮质盲的病症。短暂性皮质无力的症状、时间线和影像学表现与急性缺血性卒中或短暂性脑缺血发作等更常见的术后并发症不同。
