In some instances, when it is not possible to surgically clip an aneurysm because of its location or when the patient cannot undergo a surgical procedure because of other risk factors, embolization is an option. The procedure does not involve an open craniotomy and can be done under local anesthesia. Other methods of embolization include balloons and rapidly solidifying polymers. Surgical clipping remains the procedure of choice whenever it is possible because of its known effectiveness in permanently closing off the aneurysm to the flow of blood. Early Intervention Blood relatives of patients with aneurysms should be evaluated by a neurosurgeon since this condition is hereditary.
Early treatment can help to prevent complications.
