Cerebral arteriovenous malformation
A cerebral arteriovenous malformation (cerebral AVM, CAVM, cAVM) is a rare connection between the arteries and veins in the brain. It is an arteriovenous malformation in the cerebrum.
| Cerebral arteriovenous malformation | |
|---|---|
 | |
| Large arteriovenous malformation of the parietal lobe | |
| Medical specialty | Medical genetics  |
| Symptoms | Headache, seizures, other |
| Complications | Intracranial hemorrhage, stroke |
| Duration | Until repaired |
| Causes | Genetic |
| Differential diagnosis | Other cerebral vascular malformations, Cerebral Proliferative Angiopathy, Vascular Tumor, Glioblastoma |
| Prevention | None known |
| Treatment | Endovascular embolization, open surgery (resection), Stereotactic radiosurgery |
In serious cases, the blood vessels rupture and there is bleeding within the brain (intracranial hemorrhage). In more than half of patients with AVM, hemorrhage is the first symptom.[1]
The most problems related to an AVM, are headaches and seizures, cranial nerve deficits,[2] backaches, neckaches and eventually nausea.
