Cerebral angiography, examination of blood vessels using x-rays, of an occlusion, an intentional closure of a cerebral artery. The occlusion was obtained by the installation of metal whorls (coils) in the aneurysm, which are released at the time of an interventional radiology. This prevents aneurysmal expansion and rupture.
