Selective angiography of the intracranial vessels, is the final goal for diagnostic procedure of the intracranial lesion. If such method is possible, then more accurate diagnosis of various vascular lesions including intra-cranial aneurysm, arterio-venous malformation and thrombotic changes, can be established. Detailed analysis of changes may be taking place at the vascular wall can also be made with an aid of enlarged radiogram. Overlap of visualized vessels which have been one of the most disturbing factor can also be completely avoided. An attempt was made on dogs, to visualize small vessels located intracranially by placing a small metallic wire. Auricular artery was successfully catheterized with an aid of placement of the wire guide. In this attempt however, catheter could not pass into the middle or anterior cerebral artery. Tip of the catheter remained at the bifurcation and could not proceed further. In clinical cases, especially made needle was made to penetrate into the common carotid artery through which a red KIFA catheter was placed up to the carotid syphon. An accurate visualization of the ophthalmic artery and penetrating arteries at the base of the skull was obtained by this method. Improvement in catheter itself and the guide wire may improve this technique to accomplish the final goal. Method which Seldinger described, is too hazardous for the use of intra-carotid catheterization due to a thrombotic possibility.
