  1. The implanted 9 mm diameter stent was slightly oversized in order to prevent the moving of the stent to distal. The constant size of the stent in the growing aorta resulted in an artificial stenosis at the mid part of the descending aorta with pre- and post-stenotic dilation
  2. Prox proximal, Dist distal, Stent* diameter of the mid descending aorta at the place of the stent
