The lusoria artery is a rare congenital vascular anomaly involving most of the time the right subclavian artery. It can also be associated with a serious vascular pathology such as aortic dissection although this phenomenon is not common in the literature and most often requires rather complex surgical management because of the layout of this artery. We report a discovery of a lusoria artery case revealed by aortic dissection. This is a 63-yearold patient with recently discovered hypertension as a cardiovascular risk factor. He was received for severe chest pain. Clinical examination found grade III systolo-diastolic hypertension and tachycardia. The thoracic CT angiography found an aspect of type B aortic dissection associated with an aberrant right subclavian artery of the lusoria type. In emergency, the patient had benefited from an antihypertensive treatment allowing stabilizing his high blood pressure.
The development during hospitalization was favorable with a disappearance of the pain and a stabilization of his blood pressure levels. His discharge was made on D10 of hospitalization with a transfer to a cardiovascular surgery center for better treatment.
