Transient Cortical Blindness Associated with Endovascular Procedures for Intracranial Aneurysms
We presented three cases of transient cortical blindness secondary to contrast medium toxicity after endovascular procedures for intracranial aneurysms. Two patients noted bilateral blindness 5 or 6 hours respectively of awakening from general anesthesia for aneurysm treatment. The other one noted bilateral blindness during vertebral angiography under local anesthesia. Immediate angiography was performed in one case (Case 1), showing no arterial occlusion. CT was performed in one case that showed brain edema (Case 2).
