RESUMO
An aberrant right subclavian artery (ARSA) is a rare variation of normal anatomy occurring in 0.5% to 1.8% of the population. No current guidelines are available regarding ARSA management, and surgical intervention should be evaluated carefully. Moreover, symptomatic patients with a dominant left arch and aberrant ARSA require a surgical approach from the right side of the chest for ligation and division of the aberrant artery at its origin on the aorta. The ARSA can then be reimplanted onto the right common carotid artery via a supraclavicular incision. The extensive mobilization in the chest allows for easy reimplantation in the supraclavicular region and eliminates reliance on the collateral circulation. Postoperative monitoring is reliable and easy with radial pulse examinations.
