查询词典 occlusions

The presence of ALN in 16% of patients with branch occlusions appeared to result from variation in the lenticulostriate arteries, which arise from the middle cerebral artery branch in around 20% of cases.

本研究中，有16%的大脑中动脉分支闭塞的患者也出现了豆状核低信号征；我们认为，这可能与豆纹动脉的解剖变异有关，因为有20%的人群地豆纹动脉并非由大脑中动脉M1段发出，而是由大脑中动脉分支所发出的。

On the other hand, because the insular region is mainly supplied by the M2 segments, only loss of the insular ribbon without obscuration of the lentiform nucleus may be usually seen in type 3 or type 4 occlusions. Although there are few exceptions of type 1 occlusion manifesting a grade I CT sign in the very early period of ischemia, grade I CT signs are usually considered as supporting evidence of absent lenticulostriate artery involvement.

尽管在缺血性卒中发病后的超早期，1型大脑中动脉闭塞（大脑中动脉主干起始段闭塞）患者的深部大脑中动脉分布区可能偶尔也会出现I级早期CT征象（细微低密度区局限于岛叶，基底节区正常）；但深部大脑中动脉分布区I级早期CT征象（细微低密度区局限于岛叶，基底节区正常）的出现，通常提示豆纹动脉未受累。

In addition, the loss of the gray-white differentiation in the cortical ribbon (particularly at the lateral margins of the insula) or the lentiform nucleus and sulcal effacement can often be detected within 6 hours in up to 82% of patients with large-vessel anterior circulation occlusions.

另外，82％的前循环大动脉闭塞的患者，于发病6小时内，CT即可发现岛带征（岛叶外侧缘皮层灰白质分界消失）、豆状核低信号征、半球脑沟消失征；这些早期CT征象的出现往往提示预后不良。

Methods The high blood sugar animal model was induced by intraperitoneal injecting streptozotocin; the MACO model was made by the thread occlusions.

采用链脲佐菌素腹腔注射复制高血糖模型；线栓法制作大脑中动脉栓塞模型；应用免疫组化技术观察MMP-9蛋白表达，并测血脑屏障的通透性。

ACS patients were divided into MS group(n=51) and non-MS group (n=22) and the incidence of the multi-artery lesions 、 serious coronary stenosis , chronic total occlusions, long coronary lesions, ostial stenosis and bifurcation lesions were compared.

将73例ACS患者分成MS组51例和非MS组22例，比较两组的冠状动脉病变支数、部位、狭窄程度、病变范围和复杂病变的发生情况。

Causes of critical reduction of blood flow to the bowel range from occlusions of mesenteric arteries or veins to complicated bowel obstruction and overdistention.

肠管血流量急剧减少的原因可以从肠系膜动静脉的闭塞到复杂的肠梗阻以及过度扩张。

All parenchymatous signs and their combinations were useful for predicting internal carotid artery, M1, or branch occlusions.

所有单独或合并出现的脑实质早期CT征象都对预测颈内动脉、大脑中动脉M1段、大脑中动脉分支的闭塞有提示价值。

Neuroimaging tests might improve selection of patients who could be treated with reperfusion therapies by identifying those with regions of salvageable brain tissue, a low risk for hemorrhagic transformation, or occlusions of large arteries that might or might not be amenable to therapy.

神经影像学检查可以识别可挽救的脑组织、出血转化风险较低的区域、可治疗或不可治疗的大动脉闭塞，藉此指导我们选择合适的患者进行再灌注治疗。

He also comments on the fact that more than 60% of the time, drug-eluting stents are used in patients with "complex conditions (such as multivessel disease or acute MI) or with complex lesions (for example, saphenous-vein bypass grafts, bifurcating lesions, and chronic total occlusions)."

他也指出这样一个事实：一定期限性的药物洗脱支架多达60%用于复杂的情况（如多支血管病变疾病或者急性心肌梗死）或者复杂的损伤（如隐静脉旁路移植、分叉损伤或者长期的完全闭塞）。

Forty-two bypass graft occlusions and three significant stenoses were detected by CT and confirmed by ICA.

有42个移植旁路阻塞和3个明显的狭窄被CT检出来，并已被 ICA证实。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
