动脉狭窄

RESULTS: Of the 74 patients, 23 (31%) had ocular manifestations accompanied by other symptoms, including 3 (4.1%) with ocular syndrome accompanied with headache as the first symptoms of Moyamoya disease. Digital subtract angiography examination revealed 24 patients (32.4%) had unilateral or double stenosis of internal carotid artery, among which 3 patients had ocular syndrome. All positive eye findings included amaurosis fugax (13%), hemianopia (17%), decline or loss of the visual ability and lesions of visual fields (44%), papillary size dysfunction (13%), pupil direct/indirect light reflex (13%), ptosis (9%), nystagmus (4%), ocular dyscinesia (13%), and fossa orbitalis tenderness (9%).

结果：74例Moyamoya病患者中眼部症状与其它症状同时发生者23例（31%），其中仅以眼部症状伴头痛表现为首发症状就诊者3例（4%）；DSA检查显示单侧或双侧颈内动脉狭窄者24例（32%），其中3例患者双侧颈内动脉完全闭塞，而无任何眼部症状；23例患者所伴眼症表现主要为一过性黑朦13%，偏盲17%，视力下降甚至丧失44%，瞳孔大小异常13%，瞳孔直接/间接对光反射消失13%，上睑下垂9%，眼球震颤4%，眼球运动障碍13%，眼眶压痛9%。

PTRA was completed in 22 cases with renovascular hypertension (9 arteritis, 7 fibromuscular dysplasia and 6 atherosclerosis). The success rate was studied with angiography.

22例不同病因(大动脉炎9例，纤维肌发育不良7例，动脉粥样硬化6例)的肾动脉狭窄患者接受了PTRA术。

The study, published in the January 2005 issue of the American Journal of Roentgenology, assessed 31 patients who had greater than 60% carotid artery stenosis--18 had symptoms of carotid artery disease, including transient or permanent episodes of neurologic dysfunction, whereas 13 had no history of stroke-related symptoms.

这项研究结果发表在2005年1月《美国X线学期刊》，研究了31例颈动脉狭窄超过60％的患者：18例有颈动脉疾病的症状，包括暂时性或者永久性神经功能障碍；13例没有脑卒中相关症状的疾病史。

In patients with a seere carotid stenosis or oclusion,compensatory increases in contralateral blood flow may result in spuriously high elocities in the contralateral ICA.

严重的颈动脉狭窄或闭塞的患者，对侧颈动脉血流量的代偿性增加可能导致对侧颈内动脉的血流速度增快。

With the system, in vivo experiments were performed and the result proved the validity and feasibility of this approach. The result can be presented like this: the mean WSR value of common carotid artery from healthy adults is between 150~350s-1, and the max WSR value is between 450~750s-1; with comparing the WSR value from a male who is suffering from the internal carotid artery straitness with the natural range of WSR, a phenomenon was found that his max and mean WSR value are both smaller than the natural value evidently.

并且利用该系统进行了大量的在体实验研究，得到了相应的结果并验证了该方法的有效性及可行性，该结果显示：健康成年人的颈总动脉的血管壁剪切率平均值范围为150~350s-1，最大值范围为450~750 s-1；将患有颈内动脉狭窄的患者的血管壁剪切率与正常范围比较发现，其血管壁剪切率的最大值及平均值均显著小于正常范围。
