The New Double-Layer Micromesh Stent (Roadsaver®): Use in Endovascular Treatment of Supraaortic and Visceral Artery Aneurysms and Pseudoaneurysms

Cardiovasc Intervent Radiol. 2017 Sep;40(9):1338-1343. doi: 10.1007/s00270-017-1656-7. Epub 2017 May 5.

Abstract

Purpose: This study was designed to present our preliminary experience with the Roadsaver® double-layer micromesh (DLM) stent in the endovascular treatment of supra-aortic and visceral aneurysms and to utilize the flow-diverting effect of this new design in the treatment of these aneurysms.

Methods: DLM stent (Roadsaver®, Terumo, Tokyo, Japan) was used in five patients (median age 61.8 years; three men) for treating arterial aneurysms (one common carotid artery, one vertebral artery V1 segment, one superior mesenteric artery, and two renal artery aneurysms).

Results: All stents were successfully deployed. Follow-up imaging with conventional catheter angiography or computed tomography showed successful treatment of all aneurysms.

Conclusions: The new DLM stent appears to be promising for the treatment of supra-aortic and visceral aneurysms.
