Endovascular Thrombectomy of a Renal Artery Chimney Stent-Graft Using the Solitaire Recanalization Device

The chimney graft technique is gaining popularity as an alternative endovascular treatment for juxtarenal aneurysms not suitable for standard or fenestrated endovascular aneurysm repair (EVAR).1–6 Despite excellent technical success,1,3–6 limited data are available regarding the long-term effectiveness of the technique, particularly in terms of chimney stent occlusion. This complication may have catastrophic consequences and represents a challenge for any endovascular approach, requiring in most the cases an open surgical bypass to restore vessel patency. Donas et al.1 used open thrombectomy to treat a renal chimney graft thrombosis. We encountered a symptomatic acute thrombosis of a renal chimney stent-graft, which we successfully treated with endovascular thrombectomy using a recanalization device that, in a recent article in the JEVT, proved useful in treating acute popliteal thrombosis.7
