Abstract |
Intracranial pial arteriovenous fistulas are rare vascular lesions of the brain. These lesions are composed of one or more direct arterial feeders with a single draining vein and usually have associated venous varix or giant venous aneurysms. Pial fistulas can be treated by endovascular occlusion or by microneurosurgery and endovascular treatment offers a simple and safe option. We report a case of pial fistulas treated with embolization using n-butyl cyanoacrylate (NBCA) and Lipiodol mixture in association with a balloon in the afferent artery to slow down the flow within the fistula. |
