ABSTRACT

BACKGROUND: Effects of select medication on hemorrhage risk in patients with cerebral or spinal cavernous malformation (CM) are unknown.

METHODS: From a single-institution prospective cohort of patients with CM (2015-2021), demographics, mode of clinical presentation, and radiographic location data were collected. Follow-up was performed with electronic medical record review, in person visits and written surveys. Select medication use was ascertained from the time of the CM diagnosis to a censor date of first prospective symptomatic hemorrhage, complete surgical excision of sporadic form CM, last follow-up, or death. Using proportional hazards model (Cox Regression), we assessed effects of antithrombotic agents, fish oil, selective serotonin reuptake in inhibitors (SSRIs), Vitamin E and D supplementation, statin, and beta blockers on prospective hemorrhage risk.

RESULTS: 364 patients with spinal or cerebral CM (58.0% female; 20.0% familial; 42.3% presentation to medical attention due to hemorrhage; 25.8% brainstem) were included. During a follow-up of 2018 patient years, 103 prospective hemorrhages occurred. No studied medications increased prospective hemorrhage risk. Antithrombotic, Vitamin D supplementation, fish oil, and SSRI were associated with lower hemorrhage risk even after adjusting for age at diagnosis, hemorrhage at diagnosis, , and brainstem location.

CONCLUSIONS: Use of select medications with antithrombotic properties do not increase the risk of CM hemorrhage. Vitamin D supplementation, any antithrombotic, fish oil and SSRI were associated with a lower prospective hemorrhage risk. Further studies should evaluate the mechanism of action and potential benefit of these select medications.
