Abstract
Objective: A right-sided aortic arch is an anomaly of the aorta in early fetal life. We report a case of ruptured cerebral aneurysm with a right-sided aortic arch, which was treated by coil embolization.
Case presentation: A 60-year-old male patient was admitted on foot on the 6th day after onset of sudden headache. Neuroradiological imaging studies showed a subarachnoid hemorrhage and an aneurysm at the bifurcation of the left middle cerebral artery. During procedures for endovascular treatment, an aortic angiogram revealed a right-sided aortic arch with Kommerell's diverticulum from which the aberrant left subclavian artery originated. Coil embolization of the aneurysm was performed meticulously. The patient's postoperative course was uneventful, and the patient was discharged without any neurological deficits.
Conclusion: A right-sided aortic arch is a rare congenital anomaly, but it is crucial to have knowledge on this anomaly since it may be detected during some treatments.
