The aim of this study was to retrospectively evaluate the efficacy and safety of early pull-back of a Solitaire stent as a thrombectomy device in patients with acute ischemic stroke.
The study group comprised 23 consecutive cases presenting with acute ischemic stroke who were treated with intra-arterial therapy using the Solitaire device as a first-line endovascular procedure. The stent was deployed to cover the thrombus and then left in place for 1-2 min. Immediate angiographic results are presented. Neurologic status was assessed according to the NIH Stroke Scale score (NIHSS) and the modified Rankin Scale (mRS) score.
Successful recanalization (TICI grade ≥ 2b) was achieved in 21 of the 23 (91.3 %) treated vessels, and 6 of the patients showed immediate flow restoration after the deployment of the first stent. The mean number of passes for maximal recanalization was 1.96. There were no symptomatic procedure-related complications. Of the cases, 34.8 % improved by >10 points on the NIHSS at discharge; 30.4 % of cases revealed good functional outcome (mRS score 0-2) at 90 days.
The early retrieval technique with the Solitaire stent appears to be a safe and effective method in patients with acute ischemic stroke.
本研究旨在回顾性评估急性缺血性脑卒中患者使用 Solitaire 支架作为血栓切除术装置的早期拉回技术的疗效和安全性。
研究组包括 23 例连续就诊的急性缺血性脑卒中患者，均采用 Solitaire 装置进行动脉内治疗作为一线血管内治疗方法。支架覆盖血栓，然后放置 1-2 分钟。即刻血管造影结果。根据 NIH 卒中量表评分（NIHSS）和改良 Rankin 量表（mRS）评分评估神经功能状态。
23 例治疗血管中 21 例（91.3%）成功再通（TICI 分级≥2b），6 例患者在首次支架置入后立即恢复血流。最大再通的平均通过次数为 1.96。无症状性与手术相关的并发症。出院时，34.8%的患者 NIHSS 评分改善>10 分；90 天时，30.4%的病例显示良好的功能结局（mRS 评分 0-2）。
在急性缺血性脑卒中患者中，早期使用 Solitaire 支架取回技术似乎是一种安全有效的方法。
