The radial artery is a vessel frequently used in various medical procedures which carry a risk of complications. One such method used to minimize the number of complications is a profound knowledge of the artery’s diameter, which allows for appropriate selection of an instrument to use for puncture. The purpose of this study is to determine the diameter of the radial artery and its depth from the skin surface in young adults.

Material and methods

96 volunteers participated in the study. The average age of the volunteers was 20.43 years. All participants underwent a B-mode ultrasonography to measure the distal radial artery’s diameter. Certified anthropometric instruments were used to determine the relation between the artery diameter and the selected basic anthropometric parameters.

Results

The mean right arterial diameter for the entire examined population at the level of the styloid process was mean 1.42 (SD 0.26) mm and its distance to the skin was mean 4.00 (SD1.20) mm. Statistical analysis revealed the presence of moderate positive relationship between the diameter of the radial artery and body weight and between the diameter of the radial artery and BMI. A weak correlation between the artery diameter and the width of the wrist was also present.

Conclusion

In the present work, we aimed to determine the dimensions of the distal section of the radial artery in young people free from symptoms of cardiovascular diseases. The obtained initial study results advise selecting instruments for vascular puncture individually, with special attention paid to slender people with slim wrists.

年轻人桡动脉的超声评估——一项初步研究

桡动脉是一种经常用于各种医疗程序的血管，具有并发症的风险。One such method used to minimize the number of complications is a profound knowledge of the artery's diameter, which allows for appropriate selection of an instrument to use for puncture. 本研究的目的是确定年轻人桡动脉的直径及其距皮肤表面的深度。

材料与方法

96 名志愿者参与了这项研究。志愿者的平均年龄为20.43岁。所有参与者都接受了 B 型超声检查以测量远端桡动脉的直径。使用经过认证的人体测量仪器来确定动脉直径与选定的基本人体测量参数之间的关系。

结果

茎突水平的整个检查人群的平均右动脉直径平均为 1.42 (SD 0.26) mm，其与皮肤的距离平均为 4.00 (SD1.20) mm。统计分析显示桡动脉直径与体重之间以及桡动脉直径与BMI之间存在中度正相关。动脉直径和手腕宽度之间也存在弱相关性。

结论

在目前的工作中，我们旨在确定没有心血管疾病症状的年轻人桡动脉远端部分的尺寸。获得的初步研究结果建议单独选择血管穿刺器械，特别注意手腕纤细的苗条人。
