Coronary angiography in patients with arteria lusoria via right radial access: A case series and literature review

Transradial is becoming the access of choice for coronary angiography (CAG). Arteria lusoria (AL) poses a challenge for right transradial access because it can cause difficulty in accessing the ascending aorta. Of 18,686 patients who underwent CAG in Geisinger Medical Center from 2012 to 2018, 6 had a diagnosis of AL. Four underwent attempted right radial access, in 3 cases before AL was identified. All were successful, and one patient had successful right transradial percutaneous coronary intervention. CAG and PCI can be successfully performed using right radial access in patients with AL.
