In this procedure, the provider performs a craniotomy, removing a portion of skull bone. He then stops blood flow to an aneurysm, vascular malformation, or carotid cavernous fistula. During the procedure, the provider occludes, or blocks the blood flow, at the level of the cervical spine by placing surgical clips on the carotid artery, too. This service helps to treat aneurysms that a subarachnoid hemorrhage, congenital vascular malformation, and carotid cavernous fistula cause due to trauma, surgical damage, or rupture of an aneurysm.
