大脑中动脉(middle cerebral artery, MCA)是颅内血管狭窄最易累及的部位。对于内科治疗效果不佳的MCA狭窄患者进行血管内成形术越来越受到关注。MCA M1段血管成形的首要问题是球囊或支架到位。对于颈内动脉虹吸段过度迂曲的患者,术中应谨慎操作。另外,微导丝的正确使用也是球囊或支架到位的关键因素。在球囊扩张和释放过程...
STRATIS登记研究:大脑中动脉M2机械取栓术 Middle Cerebral Artery M2 Thrombectomy in the STRATIS Registry 在STRATIS登记研究中,尽管与M1闭塞相比,sICH的发生率有所增加,但M2闭塞取得了相似的再灌注成功率、良好的功能预后和死亡率。 基于深度学习的脑梗死自动溶栓评分:及时的原理验证研究 Deep Learning–Based Automated...
Occlusion of the middle cerebral artery (MCA) leads to a reduction of cerebral blood flow in both the striatum and the cortex, but the degree largely depends on the duration and site of the occlusion. The most common durations of transient MCAO using a suture a...
Which vascular territory is involved? Anterior cerebral artery (ACA) Middle cerebral artery (MCA) Posterior cerebral artery (PCA) All of the above What is the most likely diagnosis? Multiple infarcts in the setting of hypercoagulability Mitochondrial encephalopathy with lactic acidosis and stroke-like...

Eligible individuals suffered a first-time, unilateral, ischemic stroke in the middle cerebral artery territory that spared the diencephalon and basal ganglia 12–36 months before surgery. Individuals with persistent moderate-to-severe upper-extremity hemiparesis as defined by an FM-UE score of ≤42 ...

Traumatic brain injury (TBI) is the leading cause of disability and death, and the social burden of mortality and morbidity caused by TBI is significant. Under the influence of comprehensive factors, such as social environment, lifestyle, and employment
(intra-arterial) to the cerebral endothelium of ipsilateral hemisphere in a middle cerebral artery occlusion (MCAO) rat model of stroke. The number of docked GRPs with high VLA-4þ expression was three-fold higher compared to naive GRPs with unmodified VLA-4þ expression. Moreover, the ...
After evaluating neurological function according to the previously reported criteria84, brains were harvested to measure cerebral infarct volume using triphenyltetrazolium chloride (TTC) staining at 24 h after onset of MCAO. Transient middle cerebral artery occlusion (tMCAO) WT CD-1 mice (male, 8...
