a Selective angiography of the left renal artery anterior division confirming the presence of a 2 cm wide-necked saccular aneurysm (arrow). The parent renal artery demonstrates a beaded appearance suggestive of fibromuscular dysplasia (arrow head). b Re-modelling of the wide-necked TRAA using the Scepter C balloon (arrow) which is inflated across the aneurysm neck. The coiling microcatheter tip has been positioned within the aneurysm sac. Angiography through the guide sheath shows occlusion of flow within the aneurysm sac and distal anterior division branch. c Fluoroscopic image demonstrating the inflated Scepter C balloon (arrow) with delivery of the initial detachable coil within aneurysm sac (arrow head). d Final completion angiography demonstrating complete obliteration of the aneurysm sac by a dense coil ball (arrow) with preservation of flow into the distal anterior division branch and renal parenchyma. e Follow-up CT angiogram at 3 months demonstrating persistent occlusion of the TRAA sac with normal solitary kidney parenchymal enhancement
