  • Trial Readiness in Cavernous Angiomas with Symptomatic Hemorrhage (CASH) (CASH) Rochester, Minn.

    The purpose of this study is to set up the infrastructure for future clinical trials for patients with cavernous malformations. To do this we will be assessing the quality of MRI and data collection from patients with cavernous malformations across multiple sites in the country. At Mayo, we will be looking at new MRI "sequences" in addition to the usual sequences to see if that helps determine which cavernous malformations may bleed again.

  • Identification of risk factors and risk markers in Patients with Cavernous Malformations Rochester, Minn.

    This study aums to determine whether various markers of vascular stability are predictive of clinical events (intracerebral hemorrhage or focal neurologic deficits). The study will alos determine the prevalence of vitamin D deficiency in patients with cavernous malformation and determine if vitamin D deficiency correlates with presenting classification (Hemorrhage, Focal Neurologic Deficit, Seizure, Asymptomatic state) or natural history (hemorrhage risk).
