Westhout","Christopher L. Taylor"],"abstract":"Background: This report provides a rare documentation of spontaneous thrombosis of a ruptured aneurysm followed by delayed recanalization and subsequent rerupture. Case Description: A 47-year-old female presented with spontaneous subarachnoid hemorrhage (SAH). Four aneurysms were identified on CT angiogram including a basilar apex aneurysm, considered source of bleeding. Cerebral angiogram on postbleed day (PBD) #1 showed spontaneous thrombosis of basilar apex aneurysm. The patient was discharged to a nursing home on PBD #18 after two subsequent studies showed no recanalization of the basilar aneurysm. The patient returned on PBD #26 with a second episode of spontaneous SAH. The previously thrombosed basilar aneurysm had recanalized and reruptured, which was now treated with coil embolization. Conclusion: We are not aware of a previous report of saccular cerebral aneurysm documenting spontaneous thrombosis after SAH and recanalization with second hemorrhage. This occurrence presents a dilemma regarding the timing and frequency of subsequent cerebrovascular imaging and treatment.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/70f43e30-8702-46f4-aeec-337e8075f2c0/featured/hero-1782421005791.png","publishDate":"2014-03-28T00:00:00.000Z","doi":"10.4103/2152-7806.129615","categories":["Original Article"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2015/05/3925/SNI-5-42.pdf"}
