female, 50 year(s)
 
 
  • Figure 1
    Axial images from spiral CT.
     

    The aortic arch shows no particular modification.

     
    Area of Interest: unknown; Imaging Technique: Axial images from spiral CT.;

    At the level of the isthmus on the ventral profile of the aortic wall a hypodense structure, of rounded shape is seen in the lumen. From this image the grid of the stent seems not involved.

     
    Area of Interest: unknown; Imaging Technique: Axial images from spiral CT.;

    A slightly caudal slice shows the same hypodense structure. No contrast medium can be visualised between the structure and the aortic wall.

     
    Area of Interest: unknown; Imaging Technique: Axial images from spiral CT.;

    A caudal slice displaying the recovery of the normal profile of the aortic wall.

     
    Area of Interest: unknown; Imaging Technique: Axial images from spiral CT.;

    Multiplanar and curved CT reconstructions.
     

    The oblique multiplanar reconstruction shows clearly the position and configuration of the hypodense structure.

     
    Area of Interest: unknown; Imaging Technique: Multiplanar and curved CT reconstructions.;

    A slightly different projection from the previous one to show the presence of one grid of the stent behind the structure of interest.

     
    Area of Interest: unknown; Imaging Technique: Multiplanar and curved CT reconstructions.;

    A curved central lumen line reconstruction to display the entire lumen.
