Abstract

Cavernous malformations are low-flow vascular malformations of the central nervous system. Brainstem location and prior hemorrhage increase future hemorrhage risk. We sought to determine the influence of physical activity on hemorrhage risk. Consecutive patients with radiologically confirmed cavernous malformations participated in a prospective registry with structured, baseline interviews, surveys, and examinations. Patients were asked about unusual events prior to initial clinical presentation. Medical records and MRIs were reviewed. Patients were surveyed about their physical activity after receiving their diagnosis. Annual follow-up surveys to patients ascertained new hemorrhages. Follow-up terminated at last follow-up, hemorrhage, surgery, or death. Univariate analysis assessed the risk of physical activities on prospective hemorrhage. Of 195 patients, 117 (60%) were female. Median diagnosis age was 41 years. After diagnosis, 103 (52.8%) patients returned the physical activity survey (cerebral n = 100; spine n = 3). Over 539.4 patient years, 23 had a prospective hemorrhage. Five patients were removed from analysis because they had less than 6 weeks of physical-activity exposure before censor. The remaining 98 had no differ...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.
