Abstract
The primary method of preventing clot formation in needles or catheters during arteriography has been intermittent manual flushing. This produces a certain amount of movement of carefully placed needles. A pressurized infusor is now being used which provides a continuous flow of flushing media, eliminating manual flushing, and reduces to a minimum the movement of the needles used for the arterial punctures. The necessary components of the pressurized infusor, as well as the technique are fully described. There have been no complications whatsoever in more than 100 arterial studies of various types.
