Case Description: A 47-year-old female underwent extended TSS for a giant pituitary adenoma with gross-total resection. She developed a subarachnoid hemorrhage on the night of surgery. Angiography revealed a ruptured AcomA pseudoaneurysm, which was successfully treated with coil embolization. The patient achieved good recovery (modified Rankin Scale 1). Conclusion: Early postoperative hemorrhage after TSS should prompt early vascular imaging, as timely endovascular treatment can be life-saving.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/sni-17-392/figures/SNI-17-392-g001.jpg","publishDate":"2026-07-10T00:00:00.000Z","doi":"10.25259/SNI_474_2026","categories":["Neurovascular","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/articles/sni-17-392/SNI-17-392.pdf"}
