Abstract

Purpose: To assess the change in radial artery diameter after transradial catheterization. Methods: Two-dimensional and Doppler ultrasound evaluation of the radial artery after catheterization was performed and diffuse stenosis were observed in 38 patients and no-flow conditions were observed in 9 patients (3 months). Thirty-two out of 38 patients had late (29±5 months) evaluations. They were divided into two groups: one group whose radial artery diameter stenosis regressed to within 15% of the artery diameter before catheterization, and the other group whose radial artery diameter stenosis progressed to more than 15% of the artery diameter before catheterization. Results: Regression group diameter: befor 2.3±0.4 mm, at 3 months 1.9±0.2*mm, at 29 months 2.3±0.3 mm. Progression group diameter: before 2.3±O.4 mm, at 3 months 1.4±0.5*mm, at 29 months 1.6±0.4 mm. (p < 0.05). No-flow group: 2 patients recovered radial artery flow (1.0 mm, 1.1 mm) systemically. 2 patients experienced collateral filling from the ulnar artery. No-flow was noted in 5 patients. Conclusions: About half of the patients who had stenotic radial arteries at 3 months after catheterization had progressed farther at 29 months. We had better avoid using coronary bypass grafting after transradial catheterization.
