MRI为基础,对起病时间不明的卒中患者进行再灌注治疗

A ProspectiveMulticenter Study

一项前瞻性的多中心研究

Background andPurpose—Unclear-onset strokes are generally excluded from time-basedthrombolytic therapy. We examined the safety and feasibility of magneticresonance imaging-based reperfusion therapy in unclear-onset stroke.

背景和目的:起病时间不明的卒中往往不能进行时间为基础的溶栓治疗。我们将检验对起病时间不明的卒中患者进行MRI为基础的再灌注治疗的安全性和可行性。

Methods—Thisprospective, multicenter, single-arm study screened consecutive unclear-onsetstroke patients within 6 hours of symptom detection. Patients withperfusion-diffusion mismatch >20% and negative or subtle fluid-attenuatedinversion recovery changes were treated with intravenous tissue plasminogenactivator, intra-arterial therapy, or a combination. The safety outcome wassymptomatic intracranial hemorrhage within 48 hours after treatment. Theprimary efficacy outcome was a 3-month modified Rankin Scale score of 0 to 2.Controls were untreated unclear-onset stroke patients prospectively captured instroke registries.

方法:这个前瞻性、多中心、单臂研究筛选连续纳入症状出现6小时以内起病时间不明的卒中患者。对于灌注-弥散不匹配大于20%FLAIR无改变或仅有少许改变的患者进行静脉内组织纤溶酶原激活物、动脉内治疗或两者合用。安全性结果是治疗后48小时症状性颅内出血。主要有效性结果是3个月修正的Rankin量表评分为0-2分。对照组是卒中注册中前瞻性选取的未治疗的起病时间不明的卒中患者。

Results—Of 430unclear-onset stroke patients, 83 (19.3%) received reperfusion therapy (meanage, 67.5 ± 10.4 years; males, 66.3%; median baseline National Institutes ofHealth Stroke Scale, 14). Symptomatic intracranial hemorrhage with anyneurological decline developed in 5 patients (6.0%). Symptomatic intracranialhemorrhage with National Institutes of Health Stroke Scale worsening ≥4 developed in 3 patients (3.6%). Thirty-seven patients (44.6%) achievedmodified Rankin Scale score of 0 to 2, and 24 (28.9%) had modified Rankin Scalescore of 0 to 1. Female,baseline National Institutes of Health Stroke Scalescore, no immediate or early recanalization, and more white blood cells wereindependent predictors of poor outcome. Compared with untreated controls, thetreated group was significantly associated with good outcomes of modifiedRankin Scale score of 0 to 2 after adjusting for age, sex, and baseline NationalInstitutes of Health Stroke Scale in logistic regression analysis (odds ratio,2.25; 95% CI, 1.14–4.49).

结果:430位起病时间不明的卒中患者,83(19.3%)接受了再灌注治疗,平均年龄67.5 ± 10.4 ; 男性,66.3%; 中位基线NIHSS(美国国立卫生院卒中量表)评分:14分。5位患者出现了症状性颅内出血(神经功能不同程度损害),占6%3位出现症状性颅内出血的患者NIHSS评分增加≥4分,占3.6%37位患者(44.6%)修正后Rankin量表评分为0-2分,24位患者(28.9%)修正后Rankin量表评分为0-1分。女性、基线NIHSS评分、没有立刻或早期再通以及白细胞增高是预后不佳的独立预测因素。根据对数分析,与未治疗对照进行对比,治疗与好的预后(修正后Rankin评分0-2分,根据年龄、性别和基线NHISS评分校正)相关。(比值比, 2.25; 95% CI, 1.14–4.49)

Conclusions—Inunclear-onset stroke patients, magnetic resonance imaging-based reperfusiontherapy was feasible and safe. Randomized controlled trials are warranted toconfirm the benefit of reperfusion therapy for unclear-onset stroke.

结论:对于起病时间不明的卒中患者,MRI为基础的再灌注治疗是可行和安全的。推荐随机对照试验证实再灌注治疗对起病时间不明卒中患者的获益。

StrokeMRI为基础的再灌注治疗具备安全性和可行性

溶栓治疗有严格的时间窗要求,起病时间不明的卒中患者往往不能进行溶栓治疗。韩国蔚山现代大学医学院峨山医疗中心的Dong-Wha Kang等人通过研究发现:MRI为基础的再灌注治疗是安全可行的。相关的论文发表在Stroke杂志20121023日在线版上。
