闭塞

The joint of intervetion treatment and retroperitoneal laparoscopy and autogenetic stem cell transplantation were successful for the thromboangiitis obliterans in both initial technical and clinical aspects, which is an safe and effective treatment.

对于血栓闭塞性脉管炎患者，联合介入、腹腔镜下腰交感干切除及自体外周造血干细胞移植治疗，技术和临床成功率较高，是安全、近期疗效好的治疗血栓闭塞性脉管炎的方法，但远期疗效有待更多病例及时间上的观察。

Stenosis of internal caroid antery was found in 32 of 48 branches in 24 case. 5 branches were occlusive and 11 branches were normal. 22 cases with large or moderate cerebral infarction volume （＞5 cm3） confirmed by CT and MRI were smaller than those on MSCTPI as having abnormal perfusion lesions,which were moderate and obvious stenosis and occlusion on MSCTA. In 2 cases with small cerebral infarction volume（＜5 cm3）, MSCTPI and MSCTA revealed normal.

其中32支颈内动脉呈不同程度的狭窄，5支颈内动脉闭塞，11支血管无狭窄。22例在常规CT及MRI图像上为中及大体积梗死（＞5 cm3）的患者，MSCTPI发现与梗死灶相对应的异常灌注区，且均比常规CT及MRI图像上病灶体积大， MSCTA显示颈内动脉呈中重度狭窄或闭塞。2例未发现明显灌注异常的患者，为小体积梗死灶（＜5 cm3），MSCTA显示颈内动脉正常。

The last two types were mainly distributed at the inferior segment of popliteal artery, the superior segment of anterior and posterior tibial arteries, forming vascular anastomosing network in the whole cnemis muscle group.

晚期的下肢ASO，腘动脉、胫前动脉及胫后动脉虽闭塞，但在某些固定部位仍存在未闭塞的多个侧支，一旦此段主干动脉行内膜剥脱后即可构建远端&侧支流出道&。

Methods: We analyzed clinical characteristics of 3 patients with VOD induced by Gynura Rhizome and summarized diagnosis and therapy of VOD.

分析我院收治的3例土三七致肝小静脉闭塞病患者临床特点，对肝小静脉闭塞病诊断治疗进行总结。

Objective: To investigate clinical characteristics of adult veno-occlusive disease induced by Gynura Rhizome and to provid evidence for early diagnosis and therapy of VOD.

目的：探讨土三七致成人肝小静脉闭塞病临床特点，为肝小静脉闭塞病早期诊断治疗提供依据。

When the MCA trunk is occluded at its origin, and all of the lenticulostriate arteries are involved in ischemia (type 1 occlusion), hypodensity usually extends to the entire lentiform nucleus.

当大脑中动脉主干的起始段发生闭塞、造成所有豆纹动脉均受累缺血（1型大脑中动脉闭塞）时，通常整个豆状核区都会出现低密度

In the original studies,[4,5] all the acute stroke patients with angiographically proven internal carotid artery or M1 occlusion had ALN, presumably because the lentiform nucleus is fed by lenticulostriate arteries from M1 without collateral flow from cortical anastomoses.

先前的研究报道：所有经脑血管造影证实存在颈内动脉闭塞或大脑中动脉M1段闭塞的急性卒中患者，都会出现豆状核低信号征；可能系豆状核是由大脑中动脉M1段发出的豆纹动脉供血，缺乏来源于皮层吻合支的侧枝循环供血所致。

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。

The opening of leptomeningeal anastomoses vessel is the important way of collateral circulation in cases of serious stenosis or occlusion of MCA,the collateral flow between MCA and ACA is dominant. The RVACA/RVPCA can reflect the hemodynamic changes、the state of leptomeningeal anastomoses vessel when the MCA was serious stenosis or occlusion; There was a inverse correlation negative correlation between the RVACA/RVPCA and the NIHSS.

⑴在MCA中度以上狭窄或闭塞的情况下，皮质软脑膜吻合血管开放成为侧支循环的主要途径，以MCA-ACA之间的代偿为主；⑵RVACA和RVPCA在一定程度上可以反映MCA狭窄或闭塞时颅内血流动力学的改变、软脑膜侧支吻合的功能状况及有效程度；⑶RVACA和RVPCA与患者的NIHSS评分呈负相关，RVACA和RVPCA值越高的患者，其神经功能缺损程度越轻。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
