Hybrid repair of aberrant right subclavian artery using open and endovascular techniques.

ABSTRACT

An aberrant right subclavian artery, the most common anatomic variant of the aortic arch, occurs in 0.5% of the population. Symptoms generally result from compression of the esophagus and/or trachea as the aberrant vessel passes posteriorly in the mediastinum. Treatment includes revascularization of the right subclavian artery from the right common carotid artery using a cervical approach combined with occlusion of the origin of the aberrant vessel from the thoracic aorta. We describe a hybrid treatment approach for a symptomatic aberrant right subclavian artery using cervical revascularization and branched thoracic stent graft coverage of the origin of the aberrant vessel.
