Complex cases are reviewed at a multidisciplinary conference with professionals from all the major treatment areas. After careful consideration, an individualizes treatment plan is developed, often using a combination of microsurgery, endovascular surgery and stereotactic radiosurgery to achieve a complete cure. These lesions consist of a collection of slow flow vessels under low pressure. AOVM's may cause seizures and frequently bleed or lead blood. Severe or frequent bleeding may lead to the development of a neurological deficit.
Microsurgery is the treatment of choice for lesions that are symptomatic and accessible.
Removal of these cavernous angioma at surgery eliminates the risk of bleeding. In the case of epilepsy, surgery may cure or at least reduce the severity of seizures. Since cavernous angiomas are not visible on an angiogram, endovascular embolization is not possible. Stereotactic radiosurgery may have a role in the treatment of some deep or inaccessible lesions. However, this remains uncertain.
