  • Figure 1
    Preprocedure computed tomography evaluation

    Coronal reconstructed CE-CT images of the abdomen demonstrate a hypodense fluid collection (diamond) with a hyperdense focus of contrast (star) along the interpolar region of the left kidney, representing the...

     
    Area of Interest: Kidney; Imaging Technique: CT-Angiography; Procedure: Embolisation; Special Focus: Trauma;
     
     
  • Figure 2
    DSA-Angiography prior to embolisation

    Selective DSA-angiogram of the left renal artery demonstrates extravasation (star), fed from a subbranch of a posterior segmental artery (arrow).

     
    Area of Interest: Kidney; Imaging Technique: Catheter arteriography; Procedure: Embolisation; Special Focus: Trauma;
     
     
  • Figure 3
    DSA-Angiography post embolisation

    Selective DSA-angiogram of the left renal artery post glue embolisation (circle) shows cessation of contrast filling into the pseudoaneurysm.

  • Figure 4
    Follow-up computed tomography post embolisation

    Post treatment coronal CE-CT images of the kidneys show lack of contrast filling of the pseudoaneurysm with decreasing haematoma (diamond). Noticeable is the dense appearance of the NBCA embolus in the segmental...

Coronal reconstructed CE-CT images of the abdomen demonstrate a hypodense fluid collection (diamond) with a hyperdense focus of contrast (star) along the interpolar region of the left kidney, representing the pseudoaneurysm within a surrounding haematoma.
 
Selective DSA-angiogram of the left renal artery demonstrates extravasation (star), fed from a subbranch of a posterior segmental artery (arrow).
 
Selective DSA-angiogram of the left renal artery post glue embolisation (circle) shows cessation of contrast filling into the pseudoaneurysm.
 
Post treatment coronal CE-CT images of the kidneys show lack of contrast filling of the pseudoaneurysm with decreasing haematoma (diamond). Noticeable is the dense appearance of the NBCA embolus in the segmental subbranches (circle).
