A Simple Method to Diagnose Arteria Lusoria During Right Radial Access Coronary Intervention.

Arteria lusoria (aberrant right subclavian artery) occurs in approximately 0.1-2.4 % of all individuals. The resulting tortuosity can pose a challenge for coronary angiography using radial artery access, but also can aid in the diagnosis if not already established. This case series reports three patients diagnosed with arteria lusoria by a single low-volume catheterization operator over a 6-month period, noting that its prevalence may be higher than usually reported, can be suspected when a catheter from the right radial artery crosses the midline and forms a loop as it traverses to the ascending aorta, and that it does not preclude successful catheterization and coronary intervention.
