2018年9月5日 · LVO was defined as occlusion of the internal carotid artery and of proximal segments (M1, M2) of the middle cerebral artery. All patients with suspicion of cerebral stroke admitted to our emergency department (seen primarily by a neurologist, present 24/7) in 2015 and arriving within the time frame of 4.5 hours were included (group A).

2025年3月2日 · Large vessel occlusion (LVO), also termed proximal large vessel occlusion (PLVO), describes occlusion of a proximal and large-sized intracranial artery resulting in impending acute ischemic stroke. The definition of large vessel occlusion varies significantly among clinical trials of endovascular clot retrieval 1,2 .

LVO was defined as the presence of a contrast filling defect in any of the following segments of the proximal anterior circulation: the distal intracranial carotid artery, M1 and M2 segments of the middle cerebral artery, and A1 and A2 segments of the anterior cerebral artery.

2020年4月16日 · In this study, LVO was defined as internal carotid artery (ICA) occlusion, middle cerebral artery (MCA; M1, M2, or M3 segment) occlusion, anterior cerebral artery (A1 or A2 segment) occlusion, basilar artery occlusion, vertebral artery occlusion, and posterior cerebral artery (P1 or P2 segment) occlusion revealed by either initial magnetic ...

2021年10月16日 · 颅内大动脉闭塞 （Large artery occlusion,LAO） ，也有人称作颅内大血管闭塞 （Large vessel occlusion,LVO） ，因此下文中这两个名词都将出现。 这一原因导致脑梗死在临床上较为常见，可占各类缺血性卒中的40%以上， 其中约80%发生在前循环。

2025年2月15日 · 临床上 cta 是评估 lvo 相关缺血性卒中的常规方法，因其具有高效性且禁忌证较少，成为国内外 lvo 相关缺 血性卒中患者的首选影像学评估手段。 MRI 检查亦存在其 相关的应用限制，且需要患者高度配合，要求医院 MRI 设备24 h 开机。

2024年12月15日 · 颅内大血管闭塞（Large vessel occlusion，LVO）导致脑梗死在临床上较为常见，可占各类缺血性卒中的40%以上，其中约80%发生在前循环。根据2.0 mm阈值上限，颅内颈内动脉（ICA；典型直径3.8 mm）、MCA的M1段(2.7 mm)、基底动脉(3.2 mm)和椎动脉(2.8 mm) 归 …

虽然静脉溶栓(intravenous thrombolysis，IVT)是治疗AIS的有效方法，然而对于急性大血管闭塞性缺血性卒中(AIS with large vessel occlusion，AIS-LVO)，IVT的血管再通率较低，疗效欠佳 。因此，自20世纪80年代起就有学者开始探索经动脉内采用药物溶栓、机械碎栓、支架置入和 ...

2020年2月1日 · In this study we aimed to apply a uniform method to estimate LVO among consecutive confirmed and suspected AIS patients at 2 large-volume comprehensive stroke centers in the US using a broad definition for occlusion site that included ACA, PCA, and VA occlusions in addition to ICA, M1, M2, and BA occlusions.

We sought to estimate LVO prevalence among confirmed and suspected AIS patients at 2 comprehensive US stroke centers using a broad occlusion site definition: internal carotid artery (ICA), first and second segments of the middle cerebral artery (MCA M1,M2), the anterior cerebral artery, vertebral artery, basilar artery, or the proximal ...
