Prevalence and clinical predictors of severe tortuosity of right subclavian artery in patients undergoing transradial coronary angiography.
We investigated the prevalence and clinical predictors of severe tortuosity of the right subclavian artery (RSA) in 2,341 consecutive patients who underwent transradial coronary angiography as well as the feasibility and safety of a technique to complete transradial catheterization. Severe tortuosity of the RSA was seen in approximately 10% of these patients, and clinical predictors included systemic hypertension, female gender, older age, nonsmoker, short stature, and high body mass index. Guidewire replacement with a stiff guidewire is reliable and safe for completing transradial angiography in most patients with a tortuous RSA.
