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 ...
(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,...

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 ...
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 ...
MRA done during his first stroke showed left MCA long segment luminal narrowing. DSA done during initial stroke showed complete occlusion of superior division of left MCA with collateral flow from left anterior ...
