Case Description: A 32-year old patient presented with a spontaneous holocranial thunderclap headache for 7 days, associated with vomiting. The SAH was diagnosed with a tiny saccular aneurysm arising from the anterior communicating artery. A left pterional craniotomy and clipping of aneurysm were done. On the 3rd postoperative day, he complained of left-sided complete blindness, and on the 5th postoperative day, his GCS dropped to E4V1M5 with right-sided hemiplegia. MRI brain showed normal optic apparatus with bilateral ACA and left MCA territory infarct. Conclusion: The PION must be kept in the differential diagnosis of post-clipping sudden visual deterioration, especially following anterior communicating artery aneurysm rupture.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/d3e6bfb8-fbb2-4fbf-bc43-618c822a8f4c/featured/hero-1781562018163.png","publishDate":"2021-09-20T00:00:00.000Z","doi":"10.25259/SNI_551_2021","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/d3e6bfb8-fbb2-4fbf-bc43-618c822a8f4c/pdf"}
