The distal radial artery (dRA) approach at anatomical snuff box has gained attention of the interventional cardiologist in last few years. The procedural success rate by this novel approach depends on size of the radial artery and therefore the study was planned to study the size of distal radial artery.
Total of 1004 patients of >18 years of age undergoing coronary catheterization were included in the study. The vessel diameter was measured from media to media in the anatomical snuff box a day prior to coronary catheterization.
The mean diameter of right radial artery at conventional access site was 2.56 ± 0.35 mm and at distal access site 2.23 ± 0.39 mm (p < 0.001). Females had significantly smaller radial artery diameter as compared to males at right conventional access site (2.42 ± 0.36 mm vs 2.60 ± 0.34 mm; p < 0.001) and distal access site (2.09 ± 0.38 mm vs 2.27 ± 0.39 mm; p < 0.001). The diameter of the right dRA was not significantly correlated with age (r linear = 0.002, p = 0.0475) but was positively correlated with height and weight (r linear = 0.076, p = <0.001 and r linear = 0.005, p = <0.001) and negatively correlated with BMI (r linear = 0.076, p = 0.519).
This study has shown the size of right dRA 2.27 + 0.39 mm in males and 2.09 + 0.38 mm in females. Diabetes, hypertension, height and weight are important predictors of dRA diameter.
近年来，解剖学鼻烟窝处的远端桡动脉（dRA）入路引起了介入心脏病学家的关注。这种新方法的手术成功率取决于桡动脉的大小，因此该研究旨在研究远端桡动脉的大小。
本研究共纳入 1004 例年龄>18 岁的行冠状动脉造影术的患者。在冠状动脉造影术前一天，在解剖学鼻烟窝处从动脉壁至动脉壁测量血管直径。
右侧桡动脉常规入路的平均直径为 2.56±0.35mm，远端入路为 2.23±0.39mm（p<0.001）。与男性相比，女性右侧桡动脉常规入路（2.42±0.36mm vs 2.60±0.34mm；p<0.001）和远端入路（2.09±0.38mm vs 2.27±0.39mm；p<0.001）的桡动脉直径明显更小。右侧 dRA 的直径与年龄无明显相关性（r 线性=0.002，p=0.0475），但与身高和体重呈正相关（r 线性=0.076，p<0.001 和 r 线性=0.005，p<0.001），与 BMI 呈负相关（r 线性=0.076，p=0.519）。
本研究显示男性右侧 dRA 的直径为 2.27±0.39mm，女性为 2.09±0.38mm。糖尿病、高血压、身高和体重是 dRA 直径的重要预测因素。
