  • Figure 1
    Triphasic CT after renal biopsy

    Axial cut of triphasic CT of the abdomen after renal biopsy showing enhancement of the renal vein during the arterial phase indicating the presence of an arteriovenous fistula

     
    Area of Interest: Kidney; Imaging Technique: CT; Procedure: Biopsy; Special Focus: Fistula;
     
     
  • Figure 2
    Angiography of the renal arteries

    Selective angiography of the left renal artery showing a vascular blush seen in the lower/middle zone with appearance of the renal vein during the arterial phase, confirming the presence of an arteriovenous fistula.

     
    Area of Interest: Kidney; Imaging Technique: Catheter arteriography; Procedure: Embolisation; Special Focus: Fistula;

    Triphasic CT after embolization of Arteriovenous fistula

    Axial cut of triphasic CT of the abdomen after embolization of the left renal arteriovenous fistula showing no enhancement of the renal vein during arterial phase, indicating closure of the arteriovenous fistula.
