摘　　要：Background More and more percutaneous coronary intervention were done from radial artery approach. But the great limitation of radial artery approach and main failure cause of transradial coronary intervention is smaller size and more variations of a radial artery approach. The aim of the study is to explore the features and variations of a radial artery approach in southern Chinese populations and their clinical significance in percutaneous coronary intervention. Methods A total of 1400 patients who underwent scheduled first time transradial coronary angiography between July 2007 and September 2010 were enrolled. Radial arteriography was performed in all patients to detect the anatomical variations of this vessel. All patients＇ radial and ulnar artery inner diameters were measured using a computer assisted quantification method. A detailed patient history was recorded. Multivariate Logistic regression analysis was performed to evaluate the predictive value of variables （including age, gender, ethnicity, height, weight, body mass index, smoking, diabetes, hypertension and dyslipidemia） in arterial tortuosities and variations of this vessel. Results In southern Chinese populations, there were no significant differences in the diameters of the forearm arteries： the mean radial artery inner diameter was （3.04±0.43） mm in ethnic Han Chinese and （3.05±0.42） mm in ethnic Zhuang Chinese, P 〉0.05）, the mean ulnar artery inner diameter was （3.03±0.38） mm in Han Chinese and （3.05±0.36） mm in Zhuang Chinese, P 〉0.05）. It was estimated that the inner diameter of the radial artery was not smaller than a 6F Cordis sheath in 86.1% of male patients and in 57.0% of female patients, and not smaller than a 7F Cordis sheath in 59.3% of male patients and 24.9% of female patients. The factors found to positively affect the size of the radial artery were sex （bj=0.309, P 〈0.01）, weight （bj=0.103, P 〈0.01 ）, and diabetes mellitus （bj=-0.088, P 〈0.01） was found to negatively affect raBackground More and more percutaneous coronary intervention were done from radial artery approach.
