Abstract

The aberrant right subclavian artery (ARSA, arteria lusoria) is the most common intrathoracic vascular anomaly, affecting up to 2% of the population. However, aneurysms of congenital anomalies are extremely unusual and often present with dysphagia, dysphonia, or dyspnea due to compression of the surrounding structures. We report a case of an asymptomatic 57-year-old male with chronic kidney disease who was incidentally found to have a large aneurysm of the ARSA on preoperative computed tomography for laparoscopic nephrectomy. Surgery is unequivocally warranted as these aneurysms are associated with a high risk of complications, including thrombosis, embolism, and rupture. We debranched the ARSA, followed by anastomosis to the right carotid artery through a right neck incision. Subsequently, aneurysmal resection was performed through left thoracotomy. The patient had an uneventful postoperative recovery and was asymptomatic during the follow-up.
