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

Abstract

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

Rescue of renal function after endovascular revascularization of acute aorto-renal bypass occlusion in a patient with solitary kidney: a case report

“…Medical therapy reduces the risk of progressive ischemic nephropathy and includes antihypertensive drugs, statins, and platelet inhibition [9] . Surgical treatments include laparotomic access and thrombectomy or open surgery employing hepatic-splenorenal bypass placement [10] . Endovascular therapy consists of intra-arterial thrombolysis and mechanical thrombectomy.…”

Endovascular Renal Artery Stent Retriever Embolectomy in a Young Patient With Cardiac Myxoma: Case Report and Review of the Literature

“…The Solitaire stent retriever has been previously used for a thrombectomy of an aortic chimney stent. 19 It has also been used for coronary artery reperfusion, but never for visceral thromboemboli. 20 Visceral thromboemboli can be managed with other endovascular techniques, including thrombolysis, aspiration thrombectomy, and mechanical thrombectomy.…”
