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.
目的
本研究旨在介绍我们使用Roadsaver双层微网（DLM）支架进行主动脉弓上和内脏动脉瘤血管内治疗的初步经验，并利用这种新设计的血流导向作用来治疗这些动脉瘤。
方法
5例患者（中位年龄61.8岁；3例男性）使用DLM支架（Roadsaver，日本东京泰尔茂公司）治疗动脉动脉瘤（1例颈总动脉、1例椎动脉V1段、1例肠系膜上动脉和2例肾动脉动脉瘤）。
结果
所有支架均成功植入。采用传统导管血管造影或计算机断层扫描进行的随访成像显示所有动脉瘤均得到成功治疗。
结论
新型DLM支架在主动脉弓上和内脏动脉瘤的治疗中似乎很有前景。
