title: [Efficiency of tetracaine in digital angiography of the blood vessels of the neck].
abstract: Deglutition artifacts often degrade diagnostic quality in digital subtraction angiography (DSA) of neck vessels. In order to reduce this drawback, the authors gave a local anesthetic (Tetracaine) to the patients undergoing DSA of aortic arch and carotid arteries. Hundred-twenty-three subjects divided into two groups were examined: Tetracaine was administered to one group (64 patients) and not to the other (59 cases). In the first group deglutition artifacts were not noted in 59/64 cases. Among those patients not treated with Tetracaine/deglutition artifacts were absent in 45/59 cases. This local anesthetic did not produce important toxic reactions. Therefore the authors believe that administration of local anesthetics can reduce deglutition artifacts in DSA of neck vessels.
