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

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.
