Selective angiography of the external carotid artery and branches (author's transl)
Selective angiography of the external carotid artery and superselective angiography of single branches can be used for demonstration of blood supply of dural tumors, tumors of the skull, skull base and of facial parts of the skull. Especially malformations of vessels and their blood supply can be shown. Improvements in x-ray technique and apparatus enable movement angiography, which can be very helpful for the diagnosis of special changes. In special kinds of headache influences from outside to the external carotid artery, to the maxillary artery, to the ascending pharyngeal artery, to the posterior auricular artery, to the occipital artery and the meningeal branches can be of higher importance than was assumed before. Selective angiographies of the external carotid artery and radiographic investigations of the anatomical situation are giving the basis for planning of embolisations. For diagnosis of intra- and extra-cranial changes the neuroradiologist is the connecting person between all specialists for skull and brain.
