文题释义:
颈动脉狭窄
:由于动脉内膜粥样硬化斑等因素导致颈动脉管腔狭窄或阻塞,而导致同侧脑供血区缺血缺氧症状。如同侧视觉障碍,对侧肢体的感觉性或运动性功能障碍,若优势半球受累,则可能出现语言障碍或失语症。
Enterprise支架:是美国食品药品监督管理局FDA批准的闭环可回收自膨胀支架,由镍钛合金材料制成,采用闭合式设计。传送系统包括一条传送导丝和一个穿刺鞘。


背景:研究已证实,闭环可回收自膨胀支架Enterprise支架对颅内动脉瘤有良好的治疗效果,但其在缺血性脑卒中颅内动脉狭窄的治疗应用方面则主要集中于系列病例分析或个案病例报告方面。
目的:探讨Enterprise支架置入对动脉粥样硬化缺血性脑卒中颈内动脉狭窄治疗的有效性。
方法:研究为单中心、双盲、随机平行对照试验。试验取得患者或其监护人的书面知情同意后,将纳入研究的100例动脉粥样硬化缺血性脑卒中颈内动脉狭窄患者随机分为支架组(n=50)和药物治疗组(n=50),分别给予Enterprise支架置入+抗血小板药物治疗或单纯抗血小板药物治疗。试验共设4个访视时间点:支架置入并药物治疗或药物治疗0.5,1,2,3年。主要结局为美国国立卫生研究院脑卒中量表评估的神经功能缺损程度,次要结局为Barthel指数和颈动脉直径狭窄率。研究方案取得中国北京首都医科大学附属北京朝阳医院伦理委员会的书面批准(批准号:GJCY16012),且符合世界医学会制订的《赫尔辛基宣言》。同时已在ClinicalTrial.gov注册(NCT02802072)。
讨论:目前尚缺乏Enterprise支架置入治疗缺血性脑卒中颈动脉狭窄的远期疗效的随机对照研究。此次试验拟以此为突破口,试图证实Enterprise支架置入在缺血性脑卒中颈动脉狭窄治疗中的临床意义。

Abstract:

BACKGROUND: The Enterprise stent system is a closed-loop, recoverable self-expanding stent that is effective in the treatment of intracranial aneurysm. However, most studies on the treatment of intracranial aneurysm after ischemic stroke are case series or case reports.
OBJECTIVE: To assess the efficacy of the Enterprise stent system for the treatment of carotid artery stenosis in patients with atherosclerotic ischemic stroke.
METHODS: We will perform a single-center, double-blind, randomized parallel-controlled trial at the Department of Neurology, Beijing Chao-yang Hospital, Capital Medical University, China. A cohort of 100 patients with atherosclerotic ischemic stroke will be included after obtaining written informed consent from participants or their guardians, and then randomly allocated to undergo either Enterprise self-expanding intracranial stent implantation in combination with antiplatelet medication (stent implantation group, n= 50) or only antiplatelet medication (drug group, n= 50) for treatment of carotid artery stenosis. Four time points (0.5, 1, 2, and 3 years after stent implantation or antiplatelet medication) will be selected for outcome observation and evaluation. The primary outcome will be the National Institutes of Health Stroke Scale score, which is used to evaluate neurologic deficits. The secondary outcomes will be the Barthel index and carotid stenosis rate. The study protocol has been approved by the Ethics Committee of Beijing Chao-yang Hospital, Captical Medical University, China (approval number: GJCY16012) and will be performed in accordance with the guidelines of the Declaration of Helsinki, formulated by the World Medical Association. This trial was registered at ClinicalTrial.gov (NCT02802072).
DISCUSSION: There is a lack of randomized controlled studies addressing the long-term effects of the Enterprise self-expanding intracranial stent system for carotid artery stenosis in patients with ischemic stroke. This study will investigate and further confirm the clinical significance of the Enterprise stent system in the treatment of carotid artery stenosis in patients with ischemic stroke.
