OBJECTIVE Mechanical thrombectomy is recommended for acute ischemic stroke (AIS) with large artery occlusion. Radiation during the endovascular procedure would increase the risk of skin diseases. We sought to identify radiation outcomes during mechanical thrombectomy. METHODOLOGY We prospectively collected and analyzed radiation parameters during mechanical thrombectomy in 41 patients affected with acute cerebral artery occlusion. RESULTS There were 41 cases (68.73 ± 11.05 years) in this study, with a National Institute Health Stroke Scale (NIHSS) score of 15.66 ± 5.94. The time parameters were recorded as following: 84.45 ± 31.66 min (operation duration), 129.71 ± 81.14 s (angiographic run), 16.02 ± 11.03 min (fluoroscopy) and 18.19 ± 11.14 min (angiographic exposure). The doses produced in the procedure were: 1276.43 ± 1647.56 mGy (shot dose), 607.26 ± 412.34 mGy (fluoroscopy) and 1635.52 ± 593.65 mGy (angiographic exposure). Further analysis discovered no association between NIHSS and these time and radiation parameters (P > 0.05). CONCLUSION This study provided the description of radiation details during mechanical thrombectomy for acute cerebral artery occlusion. The stroke severity would not influence the procedure parameters.

急性缺血性卒中机械血栓切除术的放射结果。

目的 机械血栓切除术推荐用于大动脉闭塞的急性缺血性卒中 (AIS)。血管内手术过程中的辐射会增加皮肤病的风险。我们试图确定机械取栓期间的放射结果。方法 我们前瞻性地收集和分析了 41 名急性脑动脉闭塞患者在机械取栓期间的辐射参数。结果本研究共41例（68.73±11.05岁），美国国立卫生研究院健康卒中量表（NIHSS）评分为15.66±5.94。时间参数记录如下：84.45 ± 31.66 min（手术持续时间）、129.71 ± 81.14 s（血管造影运行）、16.02 ± 11.03 min（透视）和 18.19 ± 11.14 min（血管造影暴露）。程序中产生的剂量为：1276.43 ± 1647.56 mGy（注射剂量），607.26 ± 412.34 mGy（透视）和 1635.52 ± 593.65 mGy（血管造影暴露）。进一步分析发现 NIHSS 与这些时间和辐射参数之间没有关联（P > 0.05）。结论 本研究提供了对急性脑动脉闭塞的机械取栓过程中辐射细节的描述。中风严重程度不会影响程序参数。
