Stent grafts and coil embolization have revolutionised endovascular therapy of visceral aneurysms with very high clinical and angiographic success rates. Stent-assisted coil embolization is a combination of these techniques and a promising addition to the repertoire of treatment options for patients with wide-necked renal artery aneurysms. However, this technique is still in its infancy and more data needs to be collected as the long-term results remain unclear.

Stent-assisted coil embolization of a wide-necked renal artery aneurysm

Abstract
We present a case of stent-assisted coil embolization of a wide-necked renal artery aneurysm performed at our institution. The technique involved a stent being delivered over the neck of the aneurysm. Subsequently a catheter was placed into the aneurysm through the stent mesh and the aneurysm was then filled with detachable coils. Complete aneurysm occlusion was obtained and there was no evidence to suggest renal infarction on a follow-up contrast CT scan 6 months later. Our preliminary experience suggests that stent-assisted coil embolization of wide-necked renal artery aneurysms is a technically challenging but potentially effective renal-sparing endovascular approach.
