The low-profile Neuroform Atlas stent in the treatment of wide-necked intracranial aneurysms – immediate and midterm results: An Italian multicenter registry

Background and purposeWide-necked brain aneurysms therapy remains a challenge for neurointerventionalists, mainly for the high recurrence rate. Low-profile stents make feasible the treatment of these aneurysms. In our multicenter series we analyzed clinical and angiographic results of Neuroform Atlas stent-assisted coiling.Materials and methodsFrom January 2016 to March 2017, 113 wide-necked aneurysms were discovered with CTA, MRA and DSA. The Atlas stent-assisted coiling procedures were performed under general anesthesia with sequential or jailing techniques. Six months follow-up DSA was performed to assess the recurrence rate through the modified Raymond-Roy occlusion scale (RROC). Moreover, patients were evaluated clinically to analyse the degree of disability according to the mRS. MRI was performed at 12 months evaluating both the cerebral tissue and the vessels.ResultsIn all the procedures it was feasible to navigate the Neuroform Atlas to the goal vessel and deploy the stent across the aneurysmal neck. Intra-procedural complications account for the 6.2% (7/113). The immediate occlusion rate was RROC 1 in 88%, 2 in 9% and 3 in 3% of cases. The 6 months clinical data showed mRS Score 0–1 in 96.5% of patients; 3 patients died of complications related to SAH. The 12 months follow-up showed RROC of 1 in 82%, 2 in 13% and 3 in 5% of cases. No aneurysm has been retreated.ConclusionsIn our multicenter experience the Neuroform Atlas stent assisted-coiling has shown to be a safe and effective technique for the treatment of wide-necked intracranial aneurysms with encouraging clinical and angiographic results.     

Neuroform支架结合弹簧圈治疗颅内宽颈动脉瘤（附105例报告）

目的总结应用Neuroform支架结合弹簧圈治疗颅内宽颈动脉瘤的经验。方法回顾性分析采用Neuroform自膨式支架结合弹簧圈技术治疗的105例颅内宽颈动脉瘤患者的临床资料。结果105例患者中。影像学上完全栓塞98例，占933％；大部分栓塞7例，占6．7％。治愈92例，占87．6％；中重残10例，占9．5％；死亡3例，占2．9％。3-6个月随访观察未见动脉瘤复发病例。结论栓塞宽颈颅内动脉瘤时应用Neuroform支架结合弹簧圈技术，不仅可较好栓塞动脉瘤，且可防止弹簧圈突入载瘤动脉，使载瘤动脉术后通畅，从而提高了宽颈颅内动脉瘤的疗效。

Experiences of Neuroform Stent Applications for Ruptured Anterior Communicating Artery Aneurysms with Small Parent Vessel

Objective

The purpose of this study was to review the safety and durability of aneurysms treated with stent-assisted coiling of ruptured anterior communicating artery aneurysms with small parent vessels (< 2.0 mm).

Methods

Retrospective review of all ruptured aneurysm treated with stent assisted endovascular coiling between March 2005 and March 2009 at our institution was conducted. We report 11 cases of the Neuroform stent placement into cerebral vessels measuring less than 2.0 mm in diameter (range, 1.3-1.9 mm) in anterior cerebral artery. Clinical follow-up ranged from 3 to 12 months and imaging follow-up was performed with cerebral angiography at 6 months and 12 months after discharge.

Results

Complete occlusion was achieved in 10 patients, and a remnant neck was evident in one. No stent displacement or no dislodgement occurred during stent placement. There was no evidence of thromboembolic complication, arterial dissection and spasm during procedure. We performed follow-up angiography in all patients at 6 months and/or 12 months from the first procedure. The follow-up angiographic data showed successfully results except one in-stent stenosis case. All patients improved clinical performances except one patient with severe vasospasm who showed poor clinical condition initially.

Conclusion

We have safely and successfully treated 11 vessels smaller than 2.0 mm in diameter with self-expanding stents with good short and intermediate term results. More clinical data with longer follow-ups are needed to establish the role of stent-assisted coiling in ruptured aneurysms with small parent vessels.     

Neuroform支架在颅内动脉瘤栓塞治疗中的应用

目的介绍Neuroforn支架治疗颅内宽颈及梭形动脉瘤的初步应用.方法8例患者(9个动脉瘤),男性3例,女性5例;年龄41～74岁.3例为颈内动脉宽颈动脉瘤,3例(4个)为椎动脉动脉瘤,2例为基底动脉顶端动脉瘤.股动脉穿刺后常规肝素化.3 m长的Transcend 0.014交换导丝在微导管的保护下送到载瘤动脉后,通过该导丝释放支架,或直接将预装好的支架系统在205 cm长的Transcend 0.014导丝导引下送到理想的位置后释放支架,在支架释放完毕后,根据具体情况做是否进一步用电解弹簧圈(GDC)填塞.术后维持肝素化24 h.对已经用弹簧圈填塞动脉瘤的病例口服6周阿司匹林,300 mg/d,抵克立得250 mg/d.之后阿司匹林300 mg/d,维持6个月.单纯支架置入病例肝素化后仅口服阿司匹林1个月,300mg/d.结果3例(2例颈内动脉及1例椎动脉动脉瘤)放置支架后用弹簧圈完全闭塞动脉瘤.2例(3个)椎动脉动脉瘤仅放置支架,其中1例椎动脉夹层动脉瘤在3个月后复查时用GDC完全栓塞动脉瘤腔.1例基底动脉顶端动脉瘤放置支架后动脉痉挛,患者无症状,4个月后复查动脉瘤腔明显减小,GDC完全填塞动脉瘤腔.另1例基底动脉顶端动脉瘤放置支架后用GDC部分填塞动脉瘤.1例后交通动脉瘤,在弹簧圈推出过程中支架移位,颈内动脉痉挛.术后常规抗凝,20 h后动脉瘤再次出血,患者因急性脑疝死亡.结论Neuroform因其质地柔软,很容易通过弯曲的颅内血管并释放,结合GDC的填塞,可使颅内宽颈动脉瘤得到治疗,同时支架本身也能使动脉瘤形态及血流动力发生变化.但由于过分柔软,其稳定性及支撑力较差.

Endovascular Treatment of Blood Blister-Like Aneurysms Using Multiple Self-Expanding Stents

The surgical as well as endovascular treatment of blood-blister-like aneursysms (BBAs) is extremely difficult because of these pathological natures, such as small and the fragile necks. The optimal treatment of BBAs has remained uncertain. Stents are known to divert blood flow and induce thrombosis of intracranial aneurysms. We report 3 cases of successful obliteration of BBAs after multiple stents placement.
