Herein, we report a ruptured cerebral aneurysm arising from A1 fenestration combined with the accessory MCA that was successfully treated with coil embolization. Case Description: A 51-year-old woman suddenly experienced a severe occipital headache and was admitted to our hospital. Detailed examination revealed subarachnoid hemorrhage due to a cerebral aneurysm arising from A1 fenestration combined with the accessory MCA. Hence, coil embolization was performed, and a favorable outcome was obtained. Conclusion: Coil embolization of the cerebral aneurysm arising from the A1 fenestration of the ACA combined with the accessory MCA is considered to be useful.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/6cec6399-66ee-4829-9e01-6c6c1948a90a/featured/hero-1781560075607.png","publishDate":"2023-09-01T00:00:00.000Z","doi":"10.25259/SNI_507_2023","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/6cec6399-66ee-4829-9e01-6c6c1948a90a/pdf"}
