A Case of Interrupted Aortic Arch in an Adult: An Unsuspected Cause of Uncontrolled Hypertension.

In this paper, we describe an incidentally discovered case of interrupted aortic arch in a 28-year-old male patient with a history of long-standing poorly controlled hypertension. The patient presented to the hospital with a complaint of upper respiratory complaints and long-standing chest pain. A plain chest radiograph was requested to exclude a diagnosis of pneumonia, and the radiography spotted an incidental finding of inferior rib notching. A subsequent CT angiography was done for further characterization, and a diagnosis of interrupted aortic arch was confirmed. Therefore, although rare, IAA should be considered in adults with refractory hypertension or unexplained congestive heart failure.
