title: Usefulness of prominently projected aortic arch on chest radiograph to predict severe tortuosity of the right subclavian or brachiocephalic artery in patients aged >44 years undergoing coronary angiography with a right radial artery approach.
abstract: 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.
