Abstract

Background: Effects of select medications on hemorrhage risk in patients with cerebral or spinal cavernous malformations (CMs) are unknown. Methods: From a single-institution prospective cohort of patients with CM (2015–2021), demographics, mode of clinical presentation, and radiographic 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 CM diagnosis to a censor date of first prospective symptomatic hemorrhage, complete surgical excision of sporadic form CM, last follow-up, or death. Using Cox proportional hazards regression model, we assessed effects of antithrombotic agents, fish oil, selective serotonin reuptake inhibitors (SSRIs), vitamin E and D supplementation, statins, and beta blockers on prospective hemorrhage risk. Results: The study included 364 patients with spinal or cerebral CM (58.0% female; 20.0% familial form; 42.3% presentation to medical attention owing to hemorrhage; 25.8% brainstem location). During a follow-up of 2018 patient-years, 103 prospective hemorrhages occurred. No studied medications increased the prospective CM hemorrhage risk. Antithrombotics, 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 agent, 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.
