Abstract

Objectives To explore the efficacy and feasibility of the transradial approach for diagnostic coronary angiography with 4F and 5F catheter.

Methods All patients undergoing a coronary angiogram the first time were eligible to be included in the study. They were randomised to either 4F or 5F catheters. The success rate of angiography, image quality and vascular complications between two groups were compared. Two-dimensional and colour Doppler ultrasonic examination was performed on the right radial artery before procedures, 1 day and 4 weeks after procedures, respectively.

Results A total of 847 consecutive patients were randomised to 4F catheter group (n=446), including 266 (63.4%) men and 5F universal catheter group (n=401), including 271 (67.6%) men. There were no significant difference between 4F catheter and 5F universal catheter group in success rate of angiography (98.6% vs 97.1%), image quality (2.83±2.1 vs 2.88±2.31 (p>0.05)). Both groups had no death, acute thrombosis and major bleeding. The radial artery spasm and radial artery occlusion was more often on women. Intima-media thickness of radial artery had significantly increased among female patients after procedures.

Conclusion With low complication rate and better tolerance, 4F catheter should be selected in the diagnostic coronary angiography by transradial approach, especially for small built female patients.
