Transradial approach (TRA) has been more and more accepted for cardiovascular operations. TRA uncommonly leads to hemorrhagic and ascular complications. CHA2DS2-VASc score is utilized to estimation the risk of thrombosis in patients with atrial fibrillation. We intended to assess the relationship between the CHA2DS2-VASc score or components of this score and radial artery complications after transradial coronary ngiography. A total of 412 consecutive patients who underwent a TRA were evaluated in this study. Patients were divided into two groups as total complications (n= 73) and no-complications (n= 339) groups. The CHA2DS2-VASc score was higher in patients who had total complications group yet it was not statistically significant (p=.149). Total complication group were older compared to control group (p=.017). As the radial artery diameter decreased, and sheath/radial artery diameter increased, the risk of the total complication group higher significantly (for all; p<.001). Known coronary artery disease (OR: 2.230, 95% CI: 1.007- 4.975, p= .048) was independent risk factors for predictor of radial artery thrombosis, DM was an independent predictor of radial artery pseudoaneurysm (OR: 4.746, 95% CI: 1.269- 17.747, p= .021), age was an independent predictor of radial artery hematoma (OR: 1.054, 95% CI: 1.005- 1.106, p= .029) and radial artery total complications (OR: 1.047, 95% CI: 1.005- 1.087, p= .015). The CHA2DS2-VASc score alone is not connected with the risk of radial artery complications after transradial catheterization but CHA2DS2-VASc score components may help to predict complications the risk of in radial interventions.
