Cerebral arteriovenous malformation, abbreviated AVM, is a congenital developmental malformation of the cerebral blood vessels. It usually consists of arteries, veins, and arterialized veins, with no capillaries in the middle of the lesion. The malformed blood vessel mass may increase in size as the body develops, and the surrounding brain tissue may atrophy due to ischemia, and the disease is usually more common in males than in females. The first symptom of cerebral arteriovenous malformation may be intracranial hemorrhage with headache, vomiting, and impaired consciousness, while symptoms of minor hemorrhage may not be obvious. Epilepsy is also a common clinical manifestation of cerebral arteriovenous malformations, and the younger the patient, the higher the relative incidence of epilepsy. Arteriovenous malformations are most common in the frontal and temporal regions, and about one-half of patients may present with recurrent headaches. If hematoma occurs in cerebral arteriovenous malformation, corresponding neurological dysfunction can also occur, including acute hemiparesis, aphasia, etc. Patients can be further clarified through cranial CT, cranial magnetic resonance, cranial CTA and cerebral angiography. Treatments for cerebral arteriovenous malformation mainly include surgical resection, interventional embolization and stereotactic radiotherapy.
