The number of years a person can live with a cerebral vascular malformation is related to the patient’s age and whether or not the cerebral blood vessel has ruptured. If the cerebral vascular malformation is not ruptured one can live to a normal age of several years or decades. If the cerebrovascular malformation is ruptured, life expectancy will be affected and may be shortened. 1. If the cerebral vascular malformation is not ruptured, the life expectancy is the same as a normal person. Some patients do not have symptoms or have headaches and other characteristics, and the specific life expectancy varies from person to person and is related to the patient’s age. 2. If the cerebral vascular malformation rupture will lead to cause subarachnoid hemorrhage, the patient may cause brain hernia and die in a short time. In other cases, patients may suffer from limb disability due to heavy bleeding, and may be bedridden for a long period of time, and their life expectancy may eventually be shortened accordingly. Patients with cerebrovascular malformation should keep their blood pressure within normal range to avoid excessive fluctuation of blood pressure which may cause blood vessel rupture. If there is cerebrovascular malformation, it is recommended to seek medical treatment as soon as possible to clarify the severity of the condition under the guidance of a professional physician to avoid delays.
