Abstract

Right transradial coronary catheterization is very popular and performed by many clinicians with few complications. An aberrant right subclavian artery (arteria lusoria) arising from the descending thoracic aorta is an uncommon congenital variant. Here, we present the case of a patient with an aberrant right subclavian artery dissection after right transradial coronary catheterization, which is a rare complication. We diagnosed the complication by chest CT, which showed the dissection of the aberrant right subclavian artery. Dissection of an aberrant right subclavian artery is a rare complication of right transradial coronary angiograph.
