Left pulmonary artery (LPA) stenosisĀ and growth of pulmonary arteries associated with ductal stenting. A The vertical duct from the undersurface of the aortic arch, B The regular conical duct from the proximal descending aorta. C, D Pre-existing LPA stenosis. On routine follow-up angiography, there was a development of stent stenosis and LPA stenosis (E, F). Follow-up angiography images show adequate growth of pulmonary arteries despite right pulmonary artery jailing (G, H)
