加入收藏夹向本刊在线投稿目的探讨颈动脉粥样硬化及其斑块的产生与高原高血压的关系。

BACKGROUND: Pseudoaneurysms of the petrous carotid artery may occur in the setting of trauma, dissection, invasive tumors, or as a complication of surgery.

背景∶颈动脉颞骨岩部的假动脉瘤可能由于创伤、解剖操作、浸润性肿瘤而出现，或者作为手术的并发症出现。

Among the various endovascular techniques that have been tested so far, we propose self-expandable covered stents as ideal for treating arterial aneurysms and pseudoaneurysms of the petrous and cavernous carotid segments.

迄今为止各种已经检验过的血管内操作方法中，我们建议植入自我可膨胀扩张盖，这是颈动脉颞骨岩部和壁内段动脉瘤和假动脉瘤的理想治疗方法。

Thyrocervical artery had similar caliber to vertebral artery so that end-to-end anastomosis could be carried out between them, but only 38.5% of this artery had adequate artery trunk (more than 10 mm).

甲状颈干的外径与椎动脉相似，适合端端吻合，但仅有 38.5 %具有合适的血管干(大于10mm)。

The representative characteristic of the gland is that its intima and media are not ring form like those of general blood vessels but reculodromous and they extend to ducts cavity from different places and join each other to form tortuose reticulated vessels which have different shapes and sizes in diameter.

颈动脉腺的最大特点是中膜和内膜并不像一般血管形成环圈状，而是从不同部位向管腔突出延伸、相互连接构成大小不一、形状各异、迂回曲折的网状血管。

Methods: 214 patients with AVC diagnosed by transthoracic echocardiography underwent carotid artery ultrasound at the same time.

采用高频超声方法对214例AVC患者及182例年龄、性别与之相匹配的无AVC对照者的颈动脉进行了检测。

But it is still largely considered an experimental treatment for opening the clogged neck arteries that lead to strokes.

但是人们也实验性的用它来治疗可以引起卒中的颈动脉阻塞。

This effect no longer appeared after the cervical sympathetic nerve, which innervated the carotid sinus, was sectioned.

若预先切断支配颈动脉窦区的交感神经节后纤维，上述刺激腓深神经使窦神经放电增强的效应变得不明显。

More importantly, ultrasound scan revealed the carotid artery in obese children than normal children thicker and more rigid.

更重要的是，超声扫描显示肥胖儿童的颈动脉比正常孩子更厚和更硬。

MethodsThe external carotid artery of rat was ligated to observe the effect of PAMD on cerebral blood flow、cerebral vascular resistance、blood pressure and heart rate.

方法采用结扎颈外动脉的方法，观察PAMD对大鼠脑血流量、脑血管阻力、血压、心率等的影响。结果PAMD可增加脑血流量，降低脑血管阻力，对心脏功能无明显影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
