Use of Intravenous Cervical Angiography in Extracranial Vascular Disease.Dr. William F. Bouzarth.
It is well known that vascular lesions which result in stenosis or occlusion of the carotid or the vertebral arteries in their extracranial course produce ischemic brain disease. In order better to outline these sites of pathology, the technique of intravenous angiocardiography was modified. From 50 to 70 ml. of 90% diatrizoate sodium solution is rapidly injected intravenously, according to the technique of Steinberg. Twelve serial x-rays are taken 10 seconds later over a time span of 12-24 seconds. Twenty-two patients, whose ages ranged from 28 to 69, were tested. Only one showed questionable signs of neurologic damage, which was minimal and transient. This was considered to be based on an allergic reaction to the iodine compound. Five failures to visualize the carotid system were noted, but with proper timing, better positioning, and better patient cooperation, these
