Abstract

Objective: The aim of this study was to explore the factors influencing the success rate of distal transradial access (dTRA) for coronary intervention.

Methods: A total of 246 patients who underwent either coronary angiography or percutaneous coronary intervention in the Xuzhou Central Hospital were enrolled in this study. Access via the distal radial artery was the first choice for the procedure, and the success rate of this approach was recorded. All patients underwent color Doppler ultrasonography of the distal radial artery at the right anatomical snuff box in order to measure the artery diameter. The patients were divided into two groups depending on the success of the dTRA; 44 patients with unsuccessful punctures were assigned to the observation group and 202 patients with successful punctures acted as the control group. The basic clinical data of the two groups were recorded, and the differences between the two groups with respect to various indices were evaluated. Logistic regression analysis was carried out to explore the factors influencing the success rate of dTRA.

Results: Of the 246 patients, dTRA was achieved in 202, giving a puncture success rate of 82.11%. Logistic regression analysis showed that the success rate of dTRA was positively correlated with the diameter of the distal radial artery (odds ratio [OR] = 3.381, P = 0.005) and hypertension (OR = 2.427, P = 0.016), and negatively correlated with female gender (OR = 0.429, P = 0.036) and diabetes mellitus (OR = 0.325, P = 0.002).

Conclusion: The results of this study suggest that hypertension and distal radial artery diameter have a positive effect on the success rate of dTRA, while diabetes and female gender have a negative effect.
