通过观察CTA原始图像及血管重建图,明确是否存在大血管闭塞。通常将内径在2 mm及以上的血管划分为大血管,结合血管内治疗情况以及可以通过急性血管内治疗实现血运重建的血管分段,一般认为将颅外段及颅内段在内的颈内动脉(ICA)、大脑前动脉(ACA)的A1段、MCA的M1、M2段、椎动脉(VA)的V1～V4段、基底动脉(BA)、PCA的...
A 62-year-old male presented with dysarthria, contralateral hemisensory loss, and contralateral weakness, concerning for possible MCA stroke. However, close examination revealed the hemiparesis to be ataxic in nature. Imaging revealed a left PCA P2 segment occlusion and lacunar infarction of the ...
2 结果 不同部位梗死Vm的变化 A组患侧MCA的Vm(MCAVm)明显慢于健侧及对照组 (P),B组和C组患侧MCAVm与健侧及对照组比较变化不大(P);A组患侧ACA的Vm(ACAVm)明显快于对照组 (P);B组患侧ACAVm快于对照组 (P);C组ACAVm与对照组ACAVm比较无明显变化(P),但要慢于A组(P)及B组(P);各组PCA的Vm...
(MCA),大脑前动脉(ACA),大脑后动脉(PCA)的平均血流速度(Vm)均显著提高(均P<0.05),治疗第8 周末Vm提高更加显著(均P<0.01),两组间比较,差异无统计学意义(均... 胡徽星 - 《中国针灸》 被引量: 6发表: 2014年 铁锰氧化物催化过二硫酸盐降解水中对(间)氯苯胺研究 温度等因素对降解这两种有机物的影响,...

Methods Forty-one consecutive patients who presented with occlusions of either ACA, PCA or distal MCA branches were retrospectively reviewed. A comprehensive description of the affected stroke territories, post revascularization mTICI outcomes as well as the pertinent devices are presented and discussed. ...
We collected mean flow velocity (MFV), pulsatility indices (PI), and power M-mode resistance signature (absent, high, or low) in symptomatic middle (MCA), anterior (ACA), posterior (PCA), and in affected (a), ipsilateral (i), and contralateral (c-lat) cerebral arteries. Ratios of ...

On FLAIR sequences, we identified FHVs in 4 MCA regions: frontal, temporal, parietal, and insular, as well as ACA and PCA territories. Each region was scored from 0 to 2: 0 = no FHVs; 1 = 1-2 FHVs on 1-2 slices; 2 = 3 or more vessels on 1 slice or 3 or more slices ...
