Coarctation and aorto-aortic bypass: three-dimensional post-processing using multidetector row computed tomography.

Abstract

We present the case of a 61-year-old man with a history of dyspnea and disparity in blood pressure of the arms and legs due to a stenotic biscupid aortic valve and a hemodynamically relevant restenosis of a resected coarctation. The coarctation was treated with an extra-anatomic transdiaphragmal aorto-aortic bypass graft. At the same time, the biscupid aortic valve was replaced. Postoperative follow-up contrast-enhanced multidetector row computed tomography (MDCT) and three-dimensional (3D) postprocessing of the axial data sets using the volume-rendering technique was performed. This case of complex vascular structures demonstrates the potency of MDCT combined with the 3D visualization technique.
