To evaluate radial and ulnar artery diameter in patients undergoing diagnostic coronary angiography.
This was a cross-sectional study in which we measured the inner diameter of radial and ulnar artery by using two dimensional ultrasound and Doppler examination in 251 patients visiting our hospital for diagnostic coronary angiography between February to September 2008.
The mean diameter of right and left radial artery was 2.3 +/- 0.4 mm and 2.2 +/- 0.4 mm respectively. The mean diameter of right and left ulnar artery was 2.4 +/- 0.4 mm and 2.3 +/- 0.3 mm respectively. The factors found to positively influence the size of radial artery included male sex, diabetes mellitus and smoking. There was no relationship of the size of the radial and ulnar artery with body size parameters (height, weight, Body Surface Area (BSA) & Body Mass Index (BMI).
We conclude that ulnar artery diameter is larger than the radial artery in our population. Knowing the size will guide the interventional cardiologist in using appropriate size sheaths and guide catheters. Cardiac surgeons can utilize ulnar artery for bypass grafting when it is deemed unsafe to harvest the radial artery.
评估接受诊断性冠状动脉造影患者的桡动脉和尺动脉直径。
这是一项横断面研究，我们在2008年2月至9月期间，对到我院进行诊断性冠状动脉造影的251例患者，使用二维超声和多普勒检查测量桡动脉和尺动脉的内径。
右、左桡动脉的平均直径分别为2.3±0.4毫米和2.2±0.4毫米。右、左尺动脉的平均直径分别为2.4±0.4毫米和2.3±0.3毫米。发现对桡动脉大小有积极影响的因素包括男性、糖尿病和吸烟。桡动脉和尺动脉的大小与身体尺寸参数（身高、体重、体表面积（BSA）和体重指数（BMI））无关。
我们得出结论，在我们的研究人群中，尺动脉直径大于桡动脉。了解其大小将指导介入心脏病专家使用合适尺寸的鞘管和引导导管。当认为采集桡动脉不安全时，心脏外科医生可利用尺动脉进行旁路移植术。
