Isolated interrupted of aortic arch diagnosed using CT angiography: A case report and literature review

We reported a 70-year-old man with isolated IAA diagnosed using computed tomography angiography (CTA) without previous intervention. Patient concerns: The patient presented with edema of the lower extremities and productive cough. Diagnoses: CTA displayed an interruption of the aortic arch distal to the left common carotid artery (type B) and extensive collateralization. Interventions: The patient refused surgery and underwent conservative therapy with follow-up examinations because of the extensive collateral vascularization. Outcomes: The patient is still currently undergoing conservative therapy with follow-up examinations. Lessons: IAA can present in adulthood with different clinical symptoms. Careful physical examination of the lower and upper peripheral pulses in adults with a chief complaint of hypertension is of outmost importance. CTA is a useful noninvasive imaging modality for the morphologic evaluation of aortic interruption and collateral circulation.
