Consult AVM

Overall risk of bleed from AVM is 1-2% for patients without a history of bleed. Treatment modalities such as surgical resection, stereotactic radiosurgery, and embolization were discussed. These can be used alone or in combination.

Surgical AVM is obliterated at the time of surgery. Surgery has the longest "track record." Both small and large AVMs can be treated in this way. Disadvantages of surgery include operative risks, intracranial hemorrhage and possible neurological deficits.

(SRS) to lead to scar formation in the blood vessels and close the AVM. Advantages are that it does not require craniotomy. But it takes two years for protection from bleeding after radiation. Larger lesions are not easily amendable to SRS. Radiosurgical risks include radionecorsis, bleed, and neurocognitive deficits.

Embolization is less like SRS does not require a Craniotomy. Eloquent deep areas can be treated by doing small areas at a time and allowing the surrounding brain to recover. Testing of the importance of the area can be done by injection of medication into the area before permanent treatment is done. It is however, less likely than the other methods to totally obliterate the AVM when used alone.

Because angiography is part of the procedure, there is a risk of an allergic reaction to the contrast material and a risk of kidney damage in patients with diabetes or other pre-existing kidney disease.
