Objective To explore the application value of transradial artery access incoronary angiography and interventional therapy.

Methods A total of 600 patients who were selected for coronary angiography during hospitalization were selected and were randomly divided into experimental group (distaltransradial artery access, n=300) and control group (conventional transradial artery access, n=300). The main risk factors, puncture success rate, and incidence of intraoperative and postoperative complications (haemorrhage or hematoma, pseudoaneurysm, blisters, arterial occlusion) were compared between the two groups.

Results There were no statistically significant differences between the two groups in terms of sex, age, hypertension, diabetes, hyperlipidemia and body mass index (P>0.05). Compared with the control group, the experimental group had a lower success rate and longer puncture time (P < 0.05). The total complication rate of the experimental group was 2.3%, which was lower than 11.7% of the control group (P < 0.05).

Conclusion The transradial artery access has the advantages of higher safety, less postoperative complications and higher patients' comfort, which provides a good method for preventing radial artery occlusion.
