Results Thirty-one patients（77.5%）had the formation of atheromatous plaque.It mostly occurred in carotid artery crotch.Multiple blet was the major origins of cerebral infarction embolus.

结果 31例（77.5%）患者颈动脉有不同程度的粥样斑块形成，这些斑块好发于颈动脉分叉处，多发性软斑是脑梗死的主要栓子来源。

We present one case about syncope associated with neck mass. The CT scan revealed a huge central necrotic mass extending into submandibular space, oropharynx, floor of mouth and near bifurcation of carotic artery region.

本文介绍壹例与颈部肿块相关之昏厥病例，其电脑断层摄影显示一中心坏死性肿块，位於右侧舌基底部、口底、口咽区外侧及下颔下腔区，并邻近颈动脉分叉处。

IP multicast technology can use in ltol or 1 to n data transport by Internet Protocol, it force copy data on divaricating of the distributing tree is different from unicast technology that have to repeat send the same data from information source to every receivers.

它适用于多点到多点或一点到多点的数据传输业务，其基本原则是IP组播依托IP协议完成；IP组播强制网络在数据分布树的分叉处进行信息包复制，而不是由信息源节点多次重复地发送相同的数据包。

Results Masses were located at the branch of common carotid artery,so the interval between external and internal carotid arteries was enlarged.Low echoic substantial masses with clearly boundary were found.The bigger masses always grew around carotid arteries.More color flow signals were detected in the masses and most were arterial flow.

结果 颈动脉体瘤肿块位于颈总动脉分叉处，颈内及颈外动脉间距增宽，瘤体常呈实质性低回声，边界清晰，较大瘤体常围绕血管生长；彩色多普勒超声显示肿瘤内丰富彩色血流信号，以动脉血流为主，能显示瘤体与颈动脉的关系。

This study chose the Lewis, a new strain rats to have successfully established the model of regional cerebral infarction using the thread to embolize and fasten the internal carotid artery where located distantly to the bifurcation of the pterygopalatine artery and ICA, and the results had been compaired with that of SD rats.

本研究采用线栓并环扎颈内动脉与翼颚动脉分叉处远端的ICA，并在一种新品系Lewis大鼠上成功地建立了局灶脑缺血模型，并与SD大鼠进行了对比。

Methods? 67 cases of extracranial carotid artery aneurysm were treated surgically from January 1986 to June 1997.Results? There were a mortality rate of 1.5%and a hemiparalysis rate of 4.5%.Conclus ion?

？ 总结了1986年1月~1997年6月期间收治颅外颈动脉瘤67例（70个，其中颈总动脉瘤10例，颈动脉分叉处动脉瘤53例（56个），颈内动脉瘤3例，颈外动脉瘤1例。

Swirling eddies of blood form when essels branch, much like when a rier diides.

在血管分叉处会出现涡流，与河流分支非常相像。

Continuing inferiorly and anteriorly , the main trunk runs superficial to the internal carotid artery but deep to the jugular vein , external carotid artery , and styloid process to the deep surface of the stylopharyngeus muscle , which it innervates . The glossopharyngeal branch to the pharyngeal plexlus leaves the nerve trunk by the time it has crossed the stylopharyngeus muscle , and passes anteriorly and inferiorly between the internal and external carotid arteries to the main trunk to join branches of the Vagus Nerve and the cervical sympathetic nerves to form the pharyngeal plexus on the middle constrictor muscle at the level of the hyoid bone .

舌咽神经主干继续向下、向前走行于颈内动脉的表面、颈内静脉、颈外动脉及茎突的深面，横过茎突咽肌深面，绕该肌中部下缘弯向前行，并发出分支支配该肌，穿过茎突咽肌后，舌咽神经的分支一咽支脱离主干，向下向前走行于颈内动脉及颈外动脉分叉处，与迷走神经的分支及颈交感神经的分支一起组成咽丛，咽丛位于舌骨水平的咽中缩肌上。

A berry aneurysm is diagrammed at the final bifurcation of the right internal carotid artery .

图示一颅内小动脉瘤位于右颈内动脉末端分叉处。

Methods We retrospectively analyzed forty patients with cerebral infarction and the examination of carotid artery color Dopper ultrasonography.

结果 31例（77.5%）患者颈动脉有不同程度的粥样斑块形成，些斑块好发于颈动脉分叉处，发性软斑是脑梗死的主要栓子来源。
