Study on Influencing Factors of Radial Artery Occlusion after Repeated Right Radial Artery Coronary Intervention

Abstract

Objective. To investigate the risk factors of radial artery obstruction after repeated right radial coronary interventions. Methods. 497 patients who underwent repeated coronary intervention via the right radial artery in our hospital from January 2017 to January 2021 were selected and followed up for 28.07 ± 6.07 months. According to whether the right radial artery was obstructed or not, they were divided into radial artery occlusion group (n = 48) and nonradial artery occlusion group (n = 449). Results. The proportion of patients with diabetes mellitus, elevated D-dimer, and elevated LDL cholesterol was higher in the radial artery occlusion group than in the nonradial artery occlusion group ( p < 0.05 ). The radial artery occlusion group had more passage through the right radial artery often and had a longer cumulative sheath retention time than the radial artery occlusion group ( p < 0.05 ). Cumulative sheath retention time (hours) had a high predictive value for radial artery occlusion. The optimal diagnostic limit for radial artery occlusion was 2.75 h, with a sensitivity of 77.1% and a specificity of 79.5% ( p < 0.05 ). Conclusion. Diabetes mellitus, elevated D-dimer, elevated LDL cholesterol, and long retention sheath time predispose to radial artery occlusion. Cumulative duration of sheath retention is a predictor of radial artery occlusion.

Factors Affecting Radial Artery Occlusion After Right Transradial Artery Catheterization for Coronary Intervention and Procedures

“…So far, most studied have only reported the factors influencing PRAO in the PTRA path. [5][6][7] Herein, patients undergoing coronary intervention were enrolled to analyze the factors influencing PRAO and determine the best strategy to reduce PRAO and provide important information for procedural decision-making.…”

Frequency of radial artery occlusion in patients with diabetes mellitus 24.hr and one month after coronary intervention

“…The basic route for CI is the transradial channel. Reduced infiltrative radial artery exposure led to a considerable improvement in patient convenience and a decrease in punctured site problems when matched to the femoral artery method (Roffi et al, 2016;Wang et al, 2022). Because of radial artery spasms and occlusion during transradial CI, which can be triggered by the cumulative effects of catheterinduced endothelial damage and a reduction in blood circulation following membrane and catheters placement (Dwivedi et al, 2022).…”
