急性基底动脉闭塞是卒中患者死亡率最高的疾病之一,新一代血管内机械取栓装置能降低死亡率及改善临床预后。然而急性基底动脉闭塞经血管内机械取栓治疗患者临床结局受到多种因素的影响,包括患者年龄、治疗前卒中的严重程度、发病至血管开通治疗的时间、治疗前梗死体积的大小、血栓负荷及侧支循环状态等。本文就急性基底动脉闭塞血管内再通治疗进展及临床预后的影响因素做一综述。  相似文献

【摘要】 基底动脉闭塞病情重,致死率和致残率高,静脉溶栓、动脉溶栓治疗和机械取栓治疗是目前最常见的治疗方法。与静脉溶栓相比,动脉溶栓或机械取栓治疗血管再通率较高,且时间窗较静脉溶栓治疗宽,但目前的研究并未证实动脉溶栓或机械取栓治疗优于静脉溶栓治疗。桥接治疗是结合静脉溶栓与动脉溶栓或机械取栓的具有发展前景的一种治疗新模式,但其有效性还需要进一步证实。本文将对急性基底动脉闭塞相关的治疗方法:静脉溶栓、动脉溶栓、机械取栓治疗等做一综述,以促进对急性基底动脉闭塞血管再通治疗的认识。  相似文献

Background

The diffusion-weighted imaging (DWI) brain stem score (BSS) is an easy to use and can predict the clinical outcome of acute basilar artery occlusion (BAO) who underwent endovascular thrombectomy. The purpose of the current study was to validate its performance in Chinese acute BAO patients treated with mechanical thrombectomy.

Methods

Fifty consecutive patients with acute BAO who received early magnetic resonance imaging and treated with mechanical thrombectomy in a single-center were included. Early ischemic damage on DWI was evaluated by applying BSS system. Receiver operating characteristic (ROC) curve analysis was used to evaluate the performance of the score system and multivariate logistic regression analysis was performed to identify predictor of clinical outcome.

Results

Favorable outcomes were achieved in 38% patients (19 of 50 patients). Recanalization was successful in 92% patients (46 of 50 patients). Mortality rate was 26% (n?=?13/50). In ROC curve analysis, the area under ROC curve of BSS .864 (95% confidence interval [CI], .738-.945) to predict favorable and .769 (95% CI, .628-.877) to predictor mortality. In logistic regression adjusted for age, baseline National Institute of Health Stroke Scale and time to puncture, DWI BSS ≤2 (odds ratio [OR], 12.416; 95% CI, 2.520-61.179; P?=?.002) and DWI BSS >3 (OR, 7.871; 95% CI, 1.353-45.797; P?=?.022) were the independent predictor for favorable outcome and mortality at 3 months respectively.

Conclusions

The results of this study suggest that the DWI BSS can be used to predict clinical outcome in patients with acute BAO treated with mechanical thrombectomy at 3 months.  相似文献

We recently experienced self-detachment of the Solitaire stent during mechanical thrombectomy of acute ischemic stroke. Then, we tried to remove the detached stent and to recanalize the occlusion, but failed with endovascular means. The following diffusion weighted image MRI revealed no significant increase in infarction size, therefore, we performed surgical removal of the stent to rescue the patient and to elucidate the reason why the self-detachment occurred. Based upon the operative findings, the stent grabbed the main thrombi but inadvertently detached at a severely tortuous, acutely angled, and circumferentially calcified segment of the internal carotid artery. Postoperative angiography demonstrated complete recanalization of the internal carotid artery. The patient''s neurological deficits gradually improved, and the modified Rankin scale score was 2 at three months after surgery. In the retrospective case review, bone window images of the baseline computed tomography (CT) scan corresponded to the operative findings. According to this finding, we hypothesized that bone window images of a baseline CT scan can play a role in terms of anticipating difficult stent retrieval before the procedure.  相似文献

ObjectiveThe efficacy and safety of manual aspiration thrombectomy using Penumbra in an acute occlusion of large intracranial arteries has been proven in many previous studies. Our study aimed to retrospectively assess the efficacy and safety of manual aspiration thrombectomy using Penumbra in patients with small vessel occlusions (M2 segment of the MCA).MethodsWe conducted a retrospective review of 32 patients who underwent manual aspiration thrombectomy using the Penumbra 4 MAX Reperfusion Catheter for treatment of an M2 occlusion between January 2013 and November 2014. We evaluated immediate angiographic results and clinical outcomes through review of patient electronic medical records.ResultsThere were slightly more men in this study (M : F=18 : 14) and the median age was 72.5 (age range : 41–90). The rate of successful recanalization (TICI grade ≥2b) was 84% (27/32). NIHSS at discharge and favorable clinical outcomes at 3 months were significantly improved than baseline. Median initial NIHSS score was 10 (range : 4–25) and was 4 (range : 0–14) at discharge. Favorable clinical outcomes (mRS score ≤2 at 3 months) were seen in 25 out of 32 patients (78%). There were no procedure-related symptomatic intracerebral hemorrhages. One patient expired after discharge due to a cardiac problem.ConclusionManual aspiration thrombectomy might be safe and is capable of achieving a high rate of successful recanalization and favorable clinical outcomes in patients with distal cerebral vessel occlusion (M2).  相似文献

Background

Recent trials established the efficacy of mechanical stent-retriever thrombectomy for treatment of stroke patients with large vessel occlusion (LVO) in the anterior circulation. However, stent-retriever thrombectomy may not accomplish successful recanalization in all patients. The aim of this study is to report the role of bail-out permanent stenting after failure of mechanical thrombectomy.

Methods

Among 430 patients included in a prospectively maintained database, we analysed 325 cases of anterior circulation LVO. Mechanical thrombectomy (mTICI 2b-3) was effective in 213/325 (65%) and failed in 112/325 (35%). Bail-out intracranial stenting was performed in 17/325 (5.2%) patients. In all cases a fully retrievable detachable stent was used (Solitaire AB, Medtronic).

Results

No intraprocedural technical complications occurred. Successful reperfusion (mTICI 2b/3) was achieved in 12/17 patients (70.6%). Three (17.6%) patients died: one extensive infarction in the internal carotid artery territory, one large intracerebral haemorrhage, and one massive pulmonary embolism. Haemorrhagic conversion, both symptomatic and asymptomatic, occurred in 2/17 (11.7%). Good clinical outcome (mRS 0–2) at 3-months was achieved in 41.2% of patients.

Conclusion

Bail-out intracranial stenting after unsuccessful thrombectomy is technically feasible and the associated haemorrhagic risk seems acceptable in selected patients. We suggest that bail-out intracranial stenting, is safe and effective in selected patients with LVO stroke who failed to respond to thrombectomy.  相似文献
