Thirty-nine patients with severe carotid lesion contralateral to CO were studied before (1 day) and after CEA (at 7 days, 1, 3 and 6 months, and then yearly thereafter). Collateral flow and cerebral vasomotor reactivity were assessed by transcranial Doppler sonography.

对39例颈动脉严重狭窄并对侧闭塞的患者于CEA前(1天)和CEA后(7天，1，3，和6个月，以后每年)分别进行研究，应用TCD来评价侧枝血流和脑血管舒缩的反应性。

Results When the interval between the end of the injection and commencement of the irradiation was 10 s,and 5, 10 and 15 minutes, the rate of choriocapillaris occlusion was 100%,100%,0%,0%; 100%,100%,20%,0%; and 100%,100%,40%,0% with 16, 30 and 40 J/cm^2, respectively.

结果注射光敏剂距照光时间10s、5、10和15min，能量密度16、30和40J／cm^2的情况下，脉络膜毛细血管出现选择性闭塞的发生率分别为100％（10／10），100％（10／10），0％（0／10），0％（0／10）；100％（10／10），100％（10／10），20％（2／10），0％（0／10）；100％（10／10），100％（10／10），40％（4／10），0％（0／10）。

Methods Color Doppler flow imaging was used to examine the patients with unilateral severe stenosis or obstructive extracranial internal carotid artery.

方法采用彩色多普勒血流成像筛选单侧颈内动脉严重狭窄或闭塞的患者，用TCCS检测颅内主要动脉的血流动力学变化。

It is known that cardiovascular risk factors, smoking, fibromuscular dysplasia, or moyamoya disease are frequently found as an aetiological factor in patients with bilateral ICA occlusion, whereas essential thrombocytaemia, giant cell arteritis, and BD are among the very rare causes.

众所周知，双侧颈内动脉闭塞的常见病因为心血管危险因素、吸烟、纤维肌性发育不良、Moyamoya病/烟雾病/脑底异常血管网病等，而特发性血小板增多症（essential thrombocytaemia， essential thrombocythemia， ET）、巨细胞性动脉炎、白塞病则为非常罕见的原因。

The number of occluded mid-thoracic interlaminar spaces and the existence of mid-thoracic supraspinous and interspinous ligament ossification on the 3DCT images were also evaluated.

在三维立体 CT 上胸段椎板间空间闭塞的例数以及胸段棘上韧带和棘间韧带骨化的例数同样被评估。

A combination of early parenchymatous CT signs is important in predicting the arterial occlusion site in the acute stage of ischaemic stroke.

在缺血性卒中的急性期，早期CT征象对判断动脉闭塞的位置非常重要。

ABSTRACT Direct intrahepatic portacaval shunt is created between the retrohepatic IVC and portal vein intrahepatically, with partial portal flow shunted directly to the IVC. DIPS can eliminate the defect that the outflow vein—hepatic vein is vulnerable to stenosis or occlusion after TIPS.

直接性门腔分流是在肝后段下腔静脉与门脉之间建立肝内分流，将部分门脉血液直接分流入粗大的下腔静脉，解决了TIPS术后分流道引流静脉——肝静脉易狭窄或闭塞的缺陷。

There are still a lot of patients who need opening of an occluded artery and who will benefit.

仍然有很多的患者需要开通闭塞的动脉血管，并且可因此获益。

Methods Four patients with occluded dialysis fistula were taken in this study.

The foundation of thrombolytic therapy is reperfusion of the occluded artery.

使闭塞的脑血管再通是溶栓治疗的基础。
