血管狭窄

We report a case with stenosis of the main stem of the left bronchus and an emphysematous change of the left lung which shifted the heart to the right side and compressed the right lung.

我们报导了一个病例，由於左侧主支气管狭窄造成左肺气肿而使心脏右移并压迫右侧肺，同时在右侧低肺野可见一疑似垂直走向的血管阴影。

Objective To compare the efficacy of the stent-assisted angioplasty with medical conservative treatment for extracranial internal carotid artery stenosis.

Objective To summarize the short-term result and safety of treating symptomatic supra-arch extracranial artery stenosis with angioplasty and stenting.

目的 总结血管内支架成形术治疗症状性弓上颅外动脉狭窄的短期疗效和安全性。

The purpose of this study was to investigate the extracranial carotid stenosis in Chinese patients with ischemic stroke by means of computerized tomographic angiography and ultrasonography .

目的颈动脉粥样硬化是脑梗死的主要发病原因之一，本文比较CT血管造影和颈动脉超声技术检测缺血性脑梗死患者颅外颈动脉狭窄的情况。

The prevention and treatment of Hemal Heji on arterial restenosis are safe and effective.

结论和脉合剂通过抑制血管壁细胞增殖和促进凋亡，安全、有效地防治动脉再狭窄。

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 potential of angiography to evaluate the hemodynamic severity of a stenosis is limited.

血管造影对潜在的血流动力学狭窄程度的评价是有限的。

However, tracheal stent implantation is different from esophageal stent implantation. As patients with airway obstruction are always complicated by dyspnea and hypoxemia, even respiratory failure, which increases risk and difficulty of stent implantation. During tracheal stent implantation, the bronchofibroscope or stent entering the stenosis site may lead to complete tracheal obstruction-induced asphyxia. Corrosion of metal wire of stent to airway mucosa and vessels may result in hemorrhea, leading to postoperative hemoptysis. Stent dislocation is mainly caused by inappropriate selection of stent, inappropriate implantation position or severe cough. Carcinoma tissue growing along stent lumens can induce re-obstruction in stent, resulting in atelectasis relapse.

气管及食管支架置入均属有创性治疗，但气管支架置入不同于食管支架置入，气管阻塞患者均有不同程度的呼吸困难和低氧血症，甚至发生呼吸衰竭，加大了支架置入的风险和难度；气管支架置入者，当纤支镜或支架进入狭窄部位时可造成气管的完全阻塞引起窒息；支架金属丝对气管黏膜血管的侵蚀可引起大出血，导致术后咯血；支架移位主要由支架选择不当、置入不到位或剧烈咳嗽引起；癌组织沿支架网眼长入造成支架内再阻塞可引起肺不张复发。

Intimal hyperplasia resulted from local vascular inflammation is one of the main causes in RS after PTCA.

PTCA术后再狭窄的主要原因之一是血管损伤局部的炎症反应引发内膜过度增殖。

MSCTA showed stenosis and obstruction of internal carotid artery, anterior cerebral artery and middle cerebral artery, including thirteen cases with bilateral and 6 cases with single lateral. There appeared abnormal vessels looked like smog on cerebral bottom. More than one branches of collateral artery could be seen in most of them. Sacculated aneurysm of lenticulostriate artery was shown in one patient. Five patients who were performed both MSCTA and DSA displayed similar above-mentioned vascular lesions.

MSCTA均清晰显示不同程度颈内动脉虹吸段、大脑前动脉及大脑中动脉起始段狭窄、闭塞，双侧病变者13例（68.4%），单侧病变者6例（31.6%）；脑底部见纤细迂曲的&烟雾&状异常血管网；大多可显示1支以上侧支动脉；1例显示右侧豆纹动脉囊状动脉瘤。5例同时行MSCTA与DSA者，均很好显示了上述血管病变。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
