CTICasesIsolated pulmonary artery with ductal origin and pulmonary hypertension
Imaging findings
CT angiogram shows a right aortic arch, proximal interruption of the left pulmonary artery, and a patent ductus arteriosus (PDA) arising from the left subclavian artery supplying the left lung. Massive dilatation of the main PA and aorta are present.
Key takeaways
An isolated pulmonary artery is supplied by a ductus arteriosus arising from the ipsilateral subclavian artery. Chronic high-volume systemic-to-pulmonary shunting leads to severe pulmonary hypertension and dilatation of the cardiac chambers.
