Comparative analysis of the success rates of two different puncture techniques used in radial artery cerebral angiography

Objective: To compare the clinical outcomes of two types of radial artery access devices—Cordis bare steel needles and Terumo cannula needles—in digital subtraction angiography (DSA) using the transradial approach. Methods: A retrospective analysis was conducted on 574 patients who underwent DSA via transradial approach at our center. The Cordis bare steel needles were used in the Cordis group, while Terumo cannula needles were used in the Terumo group. Data was collected regarding the success rate of the first puncture performed in both groups.
