Neuroform支架结合弹簧圈治疗颅内宽颈动脉瘤

颅内宽颈动脉瘤是脑血管病治疗的难点。随着血管内介入治疗技术的飞速发展,血管内治疗已被视为主要治疗方法。鉴于单纯弹簧圈栓塞时弹簧圈易于突入载瘤动脉,无法致密填塞,因此如何防止弹簧圈脱出成为近十余年来国内外研究的热点。曾先后有报道应用重塑技术（Remodeling）、冠脉支架结合弹簧圈栓塞等方法,自波士顿公司（Boston Scientific／Target Therapeutics,Freemont,CA）生产出颅内专用自膨支架即Neuroform支架后,使用Neuroform支架结合弹簧圈成为介入治疗颅内宽颈动脉瘤的主要选择。

目的探讨使用Neuroform自膨式支架结合电解可脱弹簧圈栓塞治疗颅内宽颈动脉瘤的适应证、技术要点及并发症的防治。方法19例颅内宽颈动脉瘤均采用Neuroform支架结合电解可脱弹簧圈栓塞,其中16例采用先放置支架再将微导管经支架网孔放入瘤腔进行栓塞,另外3例是微导管进入瘤腔后再释放支架进行栓塞。结果11例宽颈动脉瘤完全闭塞,7例闭塞95%以上,1例闭塞95%以下,支架到位均满意,载瘤动脉保持通畅。结论Neuroform支架与弹簧圈联合使用是治疗颅内宽颈动脉瘤的微创、安全、有效的方法,但其远期疗效仍需随诊证实。     

支架结合弹簧圈栓塞颅内宽颈动脉瘤

颅内宽颈动脉瘤是目前手术夹闭和血管内治疗的共同难点。血管内支架在颅内宽颈动脉瘤的基础与临床方面的研究进展迅速，血管内支架的优点是：防止弹簧圈突入载瘤动脉；干扰瘤内血流模式；为新生内皮提供支撑。更易控制、更柔软以及微支架的进一步研制有助于提高颅内宽颈动脉瘤的治疗。     

Neuroform自膨支架结合弹簧圈栓塞颅内宽颈动脉瘤的护理

颅内动脉瘤是危害人类健康的严重疾病,窄颈动脉瘤的血管内治疗可获得满意结果,但宽颈动脉瘤单纯以弹簧圈栓塞方法疗效不佳.     

支架辅助弹簧圈栓塞术治疗颅内宽颈动脉瘤

目的总结支架辅助弹簧圈栓塞术治疗颅内宽颈动脉瘤的体会。方法回顾性分析2010-03—2012-03湖南省人民医院神经内科经支架辅助弹簧圈栓塞术治疗的颅内宽颈动脉瘤患者32例。结果 32例支架辅助弹簧圈栓塞术的动脉瘤,26例完全栓塞,6例大部分栓塞,其中2例发生大面积脑梗死,1例死亡。结论支架辅助弹簧圈栓塞术治疗颅内宽颈动脉瘤是安全、有效的临床技术,但须术前充分评估支架植入后对血流动力学的改变及对血管走形的可能影响。     

单纯使用Neuroform支架治疗颅内宽颈动脉瘤

近年来,颅内动脉瘤的血管内治疗发展迅速,具有微侵袭及并发症少等特点,是临床治疗颅内动脉瘤的重要手段。而颅内宽颈动脉瘤由于其瘤颈较宽,对其完全栓塞率低、弹簧圈解脱后易进入载瘤动脉造成脑梗死,目前仍是血管内治疗的难点之一。我们于2006年3月至2008年9月对12例颅内宽颈动脉瘤单纯采用Neuroform支架（Boston Scientific,USA）治疗,取得较好临床效果并总结如下。

Complications of Neuroform Stent in Endovascular Treatment of Intracranial Aneurysms

Background  The Neuroform stent can help in the treatment of difficult, wide-necked intracranial aneurysms. The objective of our study is to report some of the challenges associated with the Neuroform stent in the treatment of intracranial aneurysms. Methods  From January 2003 to August 2006, consecutive patients treated with Neuroform stent for intracranial aneurysms were prospectively enrolled. Information on patient demographics, cerebrovascular risk factors, aneurysm size and location were collected. Technical and clinical complications as well as clinical outcomes were measured. Data were analyzed retrospectively using SPSS software version 11.5. Results  Successful deployment of the stent, in the target artery, was achieved in 65/67 (97%) patients. Stent deployment failed in two cases and the migration of stent developed in one during coiling. Postoperative thromboembolic events developed in three patients. These three patients possessed hyperactive platelets, and were treated with intravenous eptifibatide. Intraoperative rupture of aneurysm developed in one patient, which was secured by subsequent coiling. Majority of the patients had good outcomes GOS (Glasgow Outcome Score) 1 or NIHSS (National Institute of Health Stroke Scale) 0 in 63/67 (94%), GOS 2 or NIHSS 2 in one patient and GOS 3 or NIHSS 4 was observed in three cases. Conclusion  Despite a low rate of intraoperative complications, post-procedural thromboembolic events were common in Neuroform stent-treated patients, which might be associated with hyperactive platelets. Further studies are warranted to identify any potential relationship between post-stent hyperactive platelets and thromboembolism.     

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.     

血管内支架治疗颅内复杂性动脉瘤的实验与临床研究

颅内动脉瘤是神经外科的常见疾病,对于复杂性(宽颈、梭形、夹层等)动脉瘤,开颅手术治疗及以往血管内介入治疗的效果均不佳。血管内支架的出现使这一现状得以改观,为颅内复杂性动脉瘤的治疗开辟了一条新的途径,但其安全性、有效性尚需进一步随访和检验。     

Matrix弹簧圈栓塞治疗颅内破裂动脉瘤的并发症

目的评价Matrix弹簧圈栓塞颅内破裂动脉瘤的安全性。方法回顾性分析应用Matrix弹簧圈栓塞的102枚颅内破裂动脉瘤的临床表现、影像学资料、治疗过程、并发症和临床结果,分析与治疗相关并发症的发生、类型、频率、相关因素和后果。结果发生并发症的有16例,其中术中动脉瘤破裂9例,血栓形成3例,弹簧圈脱出1例,载瘤动脉闭塞3例,并发症发生率为15.69%。6例患者无神经功能异常,3例患者具有暂时性神经功能异常,6例患者具有持久性神经功能障碍,1例患者死亡。与治疗相关性持久性神经功能障碍发生率和死亡率分别为5.88%和0.98%。结论应用Matrix弹簧圈栓塞颅内破裂动脉瘤和应用裸金属圈栓塞一样安全,生物活性物质不增加血栓形成的风险,但应用Matix弹簧圈栓塞远段、较小动脉瘤应慎重。

目的初步探讨Neuroform Atlas支架辅助弹簧圈治疗颅内宽颈动脉瘤的疗效及安全性。方法回顾性分析2020年8—12月郑州大学人民医院神经外科应用Neuroform Atlas支架辅助弹簧圈栓塞治疗的64例颅内宽颈动脉瘤患者(67个动脉瘤)的临床资料。其中10例患者(12个动脉瘤)同时采用尾端套叠式"Y"型支架技术治疗。术后3个月进行临床随访,采用改良Rankin量表评分(mRS)评估患者的临床预后。术后5~6个月复查数字减影血管造影(DSA),采用Raymond分级评估动脉瘤的闭塞情况。结果67个动脉瘤置入的74枚Neuroform Atlas支架均成功释放,术中发生操作相关并发症1例。67个动脉瘤的术后即刻DSA显示,56个(83.6%)动脉瘤完全闭塞(RaymondⅠ级),4个(6.0%)动脉瘤瘤颈残留(RaymondⅡ级),7个(10.4%)动脉瘤瘤体残留(RaymondⅢ级)。术后1例患者因脑疝死亡,2例发生脑梗死。术后失访3例,60例患者完成3个月随访,其中mRS 0分53例,1分4例,2分2例,3分1例。术后5~6个月,53例患者(55个动脉瘤)完成影像学随访,其中动脉瘤闭塞达RaymondⅠ级50个(90.9%),Ⅱ级2个(3.6%),Ⅲ级3个(5.5%),且均未发现支架内狭窄或迟发性血栓事件。结论初步发现,Neuroform Atlas支架辅助弹簧圈治疗颅内宽颈动脉瘤具有较高的闭塞率和较低的并发症发生率,有效性及安全性均较好。
