The bases and technical cares for the neuro-radiological study of the aorto-cervical and spinal vessels employing the retrograde catheterization according to Seldinger technic and with the Odman-Ledin catheters are reported. The authors recommend type II neuroleptanalgesia as anesthesical sedative and the use of percutaneous punction of the femoral artery or, by choice, of the axilar or humeral artery. For the selective catheterization by femoral via, they make previously an aortography, in order to know the anatomy of the supra-aortic vessels, with control through the image-inten-sifier or fluoroscopy. They employ manual injection for the study of the supra-aortic vessels and a Gidlung injector for the contrast of the ascending aorta. Complications are discussed.
