Endovascular Occlusion of a Renal Arteriovenous Fistula with Renal Vein Aneurysm Formation for Rupture Prevention

Figure 3

Representative images of an angiography during surgery and a CT scan one-month post-surgery. (a) Angiography before and after Amplatzer Vascular Plug (AVP) II Device placement. No perfusion of the left renal artery (LRA) after AVP II placement. Red arrow (dashed and dotted) = RVA; Green arrow (dotted) = correct positioned central and displaced peripheral AVP II. (b) : arterial phase images. 1: no perfusion of the LRA distal of the central AVP II. 2: minimal residual cortical perfusion over a side-branch originating from the LRA proximal of the central AVP II. : venous phase image: no contrast in the left vs. right kidney indicating subtotal infarction, despite insignificant residual cortical perfusion. No residual perfusion of the RVA (red arrows, dashed, and dotted) and marked reduction of the IVC diameter (blue arrow, dashed).
