Abstract
Using a double needle and X-ray television monitoring, selective angiography of the external carotid artery was performed in 25 patients with head or neck tumors. Good correlation was obtained between the surgical and radiographic findings. Location and invasion of the tumor, and in some cases the nature of the tumor, were determined by this technique, based on the dislocation, disappearance of hypervascularization of the artery. In combination with another radiographic method, selective external carotid angiography seems to be a promising technique for diagnosis of head and neck tumors.
