Patient
male, 85 year(s)
 
 
  • Figure 1
    CT angiography - axial plane

    CTA scan shows the circumference of the intimal intussusception in the aortic arch.

     
    Area of Interest: Arteries / Aorta; Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Acute;
     
     
  • Figure 2
    CT angiography - sagittal MPR

    Intimo-intimal intussusceotion with intimal flap detached and wrapped in the arotic arch (arrow), the ascending aorta being the false lumen (*). Proximal flap in the aortic root (arrowhead).

     
    Area of Interest: Arteries / Aorta; Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Acute;
     
     
  • Figure 3
    CT angiography - sagittal MPR

    In addition to the invaginated flap in the aortic arch, dissection of the supraaortic branches dissection (arrow) and of the descending aorta (arrowhead) is also detected. Proximal flap in the aortic root (short arrow).

     
    Area of Interest: Arteries / Aorta; Cardiovascular system; Imaging Technique: CT-Angiography; Procedure: Computer Applications-Detection, diagnosis; Special Focus: Acute;
     
     
  • Figure 4
    CT angiography - sagittal MPR

    There is aneurysmal dilatation of the ascending aorta, invagination of the intimomedial flap in the aortic arch (arrow) and aortic dissection with two lumens in the descending aorta (arrowhead).
