Left distal radial artery approach versus conventional radial artery for coronary angiography

Abstract

We aimed to evaluate feasibility, contrast utilization and complications of trans-radial approach comparing the left distal trans-radial artery (lt. dTRA) access versus conventional right trans-radial artery (rt. TRA) access in coronary angiography.

Subjects and methods

This study was conducted on (100) patients who underwent coronary angiography (50 patients via lt. dTRA & 50 patients via rt. TRA) and was performed in the department of cardiology, Benha University Hospital. All patients performed ECG, echocardiography, arterial doppler pre and post procedures.

Results

In comparison with conventional right trans-radial artery (rt. TRA), Our study revealed that performing coronary angiography via lt. dTRA had more difficulties at which it had significantly more failure rate to get puncture and high significantly more time to insert a sheath but with significantly less contrast volume required. Also, lt. dTRA approach had significantly less incidence to cause radial artery occlusion and less incidence to cause bleeding or infection without significant difference. Patients were more satisfied when procedures performed via lt. dTRA approach and they had less hospital stay time.

Conclusions

Compared to conventional right trans-radial artery (rt. TRA) access for coronary angiography procedure, left distal trans-radial artery (lt. dTRA) access has more failure rate to get puncture and more time to insert sheath but with less contrast volume required, less incidence of RAO and less hospital stay time.
