Cerebral AVM Treatment
A cerebral arteriovenous malformation may not be detected until it bleeds. A small cerebral arteriovenous malformation (AVM) that is not bleeding may not require treatment. Treatment of a cerebral AVM depends on the size of the AVM, location, and a person's age. A bleeding cerebral arteriovenous malformation usually causes blood to collect in the space between the brain and the lining to the brain. This bleeding is called a subarachnoid hemorrhage.
A ruptured cerebral arteriovenous malformation is usually treated with surgery. During surgical resection, a neurosurgeon places a tiny clip on the AVM in order to stop blood from flowing to it, and then the malformation is carefully removed. A piece of the skull is removed by the neurosurgeon to provide access to the arteriovenous malformation for surgical clipping. Another surgical treatment, endovascular embolization, involves placing a small plug into the arteriovenous malformation. A catheter is threaded to the arteriovenous malformation after it is inserted into an artery in the groin. The plug is delivered through the catheter. Once the plug is placed in the artery that supplies the malformation, blood stops flowing into it. Considerable rehabilitation may be required for those who experience damage to the brain from a ruptured cerebral arteriovenous malformation.
Treatment for cerebral arteriovenous malformation may include:
- Surgery for cerebral arteriovenous malformation
- A clip closes the abnormal communication between the artery and the vein
- The arteriovenous malformation is removed by the surgeon.
- Endovascular embolization
- Focal beam radiation for cerebral arteriovenous malformation:
- Small doses of radiation gradually close the aneurysm.
Treatment for subarachnoid hemorrhage may include:
