    CT angiograhy: MPR image shows the short stenosis at the ostium of IMA

     
    Area of Interest: Vascular; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Obstruction / Occlusion;

    VR image confirms the stenosis of the ostium of IMA and the hypertrophy of Riolano's arch with rehabitation of SMA and coeliac trunk.

     
    Area of Interest: Vascular; Imaging Technique: CT-Angiography; Procedure: Diagnostic procedure; Special Focus: Obstruction / Occlusion;

    CT angiograhy: MIP image shows the occlusion of CTr

    Angiography
     

    Preliminar angiography confirms the stenosis of IMA

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Diagnostic procedure; Special Focus: Obstruction / Occlusion;

    Hypertrophic aspect of "Riolano's arch".

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Diagnostic procedure; Special Focus: Obstruction / Occlusion;

    Delayed opacification of SMA.

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Diagnostic procedure; Special Focus: Obstruction / Occlusion;
     
     
  • Figure 3
    Angiography

    Under fluoroscopy the stenosis was negotiated with angiographic microguidewire (Thruway-Boston)

     
    Area of Interest: Vascular; Imaging Technique: Fluoroscopy; Procedure: Catheters; Special Focus: Obstruction / Occlusion;
     
     
  • Figure 4
    Angiography
     

    Fluoroscopy shows positioning of balloon-expandable stent at the ostium of IMA (Dynamic-Renal Biotronik).

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Ablation procedures; Special Focus: Abscess;

    Balloon inflation of the stent.

     
    Area of Interest: Vascular; Imaging Technique: Catheter arteriography; Procedure: Angioplasty; Special Focus: Obstruction / Occlusion;
