Transient cortical blindness is a known complication after cerebral and vertebral angiography although is a rare complication following cardiac catheterization. In this report, we describe a seventy-six-year-old male patient who had cortical blindness after coronary bypass graft angiography. The development of cortical blindness, in this setting, appears to be an osmotic disruption of the blood-brain barrier which is selective for the occipital cortex. Other hypotheses, such as an immunological reaction to the contrast agent or a direct injection of dye into the vertebral artery system, were considered. The clinical outcome is usually favourable, with vision completely restored within 24-48 hours, as was the case of the patient described in the present report.
短暂性皮质盲是脑血管造影和椎动脉造影术后已知的并发症，尽管在心脏导管插入术后是一种罕见的并发症。在本报告中，我们描述了一名76岁男性患者，其在冠状动脉搭桥术后血管造影后出现皮质盲。在这种情况下，皮质盲的发生似乎是血脑屏障的渗透性破坏，这种破坏对枕叶皮质具有选择性。还考虑了其他假说，例如对造影剂的免疫反应或染料直接注入椎动脉系统。临床结果通常是良好的，视力在24 - 48小时内完全恢复，本报告中描述的患者就是如此。
