[Advantages in the use of teflon-catheter cannulas, compared with needles, for direct carotid angiography (author's transl)].
A method for direct carotid puncture, using a Teflon-catheter cannula, is described. The complication rate of this method is compared with the usual technique using a rigid cannula. The significant advantage of using the Teflon-cannula consists in: 1. In the absence of sub-intimal contrast injection and 2. The possibility of selectively demonstrating the internal or external arteries from the common carotid.
