Figure 2: Immediately after stent implantation, an angiogram of the transverse aortic arch (a) demonstrates a marked improvement in thoracic aortic caliber and continued patency of the aortopulmonary collateral (arrow); note that the collateral does not fill as densely with contrast due to brisker antegrade aortic flow after intervention. Three-dimensional reconstruction from cardiac computed tomography angiogram of the aorta 1 year after intervention from right anterior oblique (b) and posterior (c) views shows persistent patency of the stented aortic segment and the aortopulmonary collateral supplying a segment of the right lung (arrow)
