Combined CASPER stenting and Onyx embolisation. a A large right renal artery aneurysm (white arrows) was accessed with a guidesheath (thick black arrow) and inner diagnostic catheter (thin black arrow). b With the guidecatheter retracted proximally) a 7 × 25 mm CASPER stent (black arrow) was subsequently deployed over the aneurysm neck with a Rebar-14 microcatheter (white arrow) jailed within the aneurysm. Note mild contrast stasis. c A significant inflow jet was observed and as such a small volume of Onyx HD 500 (black arrow) was slowly injected to promote thrombosis. c and d Note all the segmental renal artery branches remained patent with near complete stasis and occlusion observed at the conclusion of the procedure
