[Direct percutaneous carotid angiography with the Potts-Cournand cannula system (author's transl)]

The indications for carotid angiography and the complications of this procedure are described. A report is given on the technique used in this department for direct percutaneous carotid angiography. A comparison of the PC cannula system in current use -- available in throw-away package form -- with the Buchtala cannula system shows a reduction in the incidence of intra/extramural contrast agent injections.
