Although it is well known that certain characteristics, such as older age, female gender, hypertension, and high body mass index, are closely associated with severe arterial tortuosity among patients undergoing transradial coronary angiography, few data are available regarding useful predictors of severe arterial tortuosity among geriatric patients. The purpose of the present study was to evaluate the characteristics of geriatric patients with severe tortuosity of the right subclavian artery or brachiocephalic artery. The coronary angiographic reports of patients with severe tortuosity of the right subclavian artery or brachiocephalic artery and age- and gender-matched control patients were retrospectively evaluated. A total of 847 consecutive patients underwent right transradial coronary angiography. Of these patients, 48 (5.7%) had severe tortuosity (29 women, age 73.4 ± 8.6 years). The factors associated with severe arterial tortuosity were greater body mass index (odds ratio 1.17, p = 0.02), the presence of a prominently projected aortic arch on a chest radiograph (odds ratio 5.62, p <0.01), and lower serum creatinine value (odds ratio 0.05, p <0.01). In conclusion, the presence of a prominently projected aortic arch on the chest radiograph is a useful predictor of severe arterial tortuosity.
虽然众所周知，某些特征，如年龄较大、女性、高血压和高体重指数，与经桡动脉冠状动脉造影患者的严重动脉迂曲密切相关，但关于老年患者严重动脉迂曲的有用预测因素的数据很少。本研究的目的是评估右锁骨下动脉或头臂动脉严重迂曲的老年患者的特征。回顾性评估了右锁骨下动脉或头臂动脉严重迂曲且年龄和性别匹配的患者的冠状动脉造影报告。共 847 例连续患者接受了右经桡动脉冠状动脉造影。其中 48 例（5.7%）存在严重迂曲（29 名女性，年龄 73.4 ± 8.6 岁）。与严重动脉迂曲相关的因素包括较大的体重指数（优势比 1.17，p = 0.02）、胸片上主动脉弓突出（优势比 5.62，p <0.01）和较低的血清肌酐值（优势比 0.05，p <0.01）。总之，胸片上主动脉弓突出是严重动脉迂曲的一个有用预测因子。
