Magnetically Controlled Focal Intravascular Thrombosis in Dogs

Abstract

HE mortality and morbidity resulting from ruptured intracranial aneurysms serves as an impetus to the surgeon to develop improved methods of therapy. Although it might seem logical to employ early craniotomy in the treatment of the patient with a ruptured aneurysm and thereby remove the risk of recurrent hemorrhage, numerous authors have demonstrated the high operative mortality of such a procedure. 5-11 One cause of this mortality is the vasospasm and subsequent infarction which follows surgical manipulation of the already irritated blood vessels. It is possible, however, that a stereotaxic method of treatment which would produce immediate thrombosis of the aneurysm but not require manipulation and retraction of the traumatized brain might significantly improve the aneurysm patient's
