动脉狭窄

Methods On the operation process of the 15th patient suffered actual anal scar straitness deformity, We have designed an axial pattern skin flap whose axes is inferior rectum artery branches or scrotum, and the crissum wound caused by excising scar with ring coverage.

在15例真性肛门瘢痕狭窄畸形患者手术过程中，设计以直肠下动脉皮支或阴囊后动脉为轴心血管的轴型皮瓣，环形覆盖切除瘢痕后形成的肛周创面。

Results: The patients with type 2 diabetes lower limb vascular lumen of atherosclerotic plaque, stenosis or occlusion were significantly higher, and type 2 diabetes lower extremity vascular disease, to small blood vessels below the popliteal artery lesions mainly especially the dorsalis pedis artery.

结果：2型糖尿病组患者下肢血管管腔的粥样硬化斑块、狭窄、闭塞的发生率明显高于对照组，且2型糖尿病组下肢血管病变，以腘动脉以下的中小血管病变为主，尤以足背动脉为著。

Among the results of contrast medium chase DSA, 34 samples got clear images, only 2 samples of image showed movement artifacts. Different stenosis or emphraxis of below-popliteal arteries were existed in all patients, among them, 23 patients combined with severe stenosis of femoral superficial arteries.

结果：全部DSA检查均获得成功，对比剂跟踪DSA检查结果中，34例次造影图像优良，2例次采集的图像有移动性伪影；全部患肢均存在胭动脉以下血管不同程度的狭窄或闭塞，其中23例合并股浅动脉重度病变。

Result The CTA of vertebral artery can find all kinds of abnormal ,example hypogenesis stenosis,formation of atheroselerotie plaque and calcification,and press by surrounding tissue, and affect the blood stream of vertebral artery directly.

结论椎动脉CTA可以发现椎动脉的先天狭窄、管壁内粥样斑块形成及其钙化，以及受周围组织挤压，均能引起TIA。

It was suggested that structure changes such as incurvation and stenosis of the vertebral artery caused by spondylopathy were reasons of cervical vertigo.

结果表明，颈椎病所致的椎动脉弯曲、狭窄等结构改变是引起颈性眩晕的主要原因，而转颈时椎动脉的上述改变明显加重。

Atherosclerosis involved progressive luminal narrowing until the blood flow was compromised to the point that organ metabolic needs could no longer be met, producing ischemia and infarction of the subtended tissue such as the heart or the brain.

D 斑块破裂：早期，对於动脉粥样硬化症的观念涉及到动脉腔变得愈来愈狭窄，直到血流有障碍而不再能够满足器官新陈代谢的需求，而导致对向组织的局部缺血与梗塞，例如心脏或脑部。

We analyze they are concerned with arterial diameter, stegnosis degree, anatomical position among arteries, compensatory circulation, the fixing of TCD, artery variation, angiospasm and the reliability of DSA.

我们分析与动脉管腔大小、狭窄程度、动脉之间的解剖位置、侧支循环代偿、TCD定位不准、颅骨对超声波的吸收，及血管变异和吻合、血管痉挛、代偿性高流速、DSA结果的可信度等有很大关系。

Atherosclerotic/calcific aortic stenosis, on the other hand, develops at later in life and is a manifestation of diffuse atherosclerosis that commonly affects elderly individuals.

另一方面，动脉粥样硬化/钙化性主动脉瓣狭窄出现的时期更晚，表现为广泛的动脉粥样硬化，常好发于老年人。

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。

Results The clinical manifestations of TOBS comprised transient unconsciousness, vertigo, dyskinesia of eyeball, abnormality of pupils, dyskinesia of limbs, hemianopsia or cortical blindness, ataxia and memory impairment. MRI showed the local infarction in thalami, cerebellum, midbrain, pons, occipital lobe, temporal inner surface. The features of DSA were occlusion or stenosis in basilar artery and vertebral artery.

结果 TOBS的临床主要表现为一过性意识障碍、眩晕、眼球运动障碍及瞳孔的变化、肢体运动障碍、偏盲或皮质盲、共济失调及记忆功能损害；磁共振显示梗死灶在丘脑、小脑、中脑、脑桥、枕叶、颞叶内侧面；数字减影血管造影显示为基底动脉及椎动脉闭塞或狭窄。

The reasons of iron ions content overproof in grade Ⅱ desalting water system,such as variation water quality,contamination of regenerant , operation adjustment of pretreatment system and switching operation of bed were discussed.

对二级脱盐水系统中铁离子含量超标的原因，如来水水质发生波动、再生剂受到污染、预处理系统操作调整、床体运行切换等进行了论述。
