大脑动脉环前部破裂动脉瘤的病理研究

The pathological studies on ruptured aneurysm in anterior Willis circle

大脑动脉环后交通动脉的形态观察

Morphometric study of the posterior communicating artery in cerebral arterial circle of Willis

上述动脉的分支于垂体周围形成大脑动脉环。

The above mentioned branches contribute to the formation of cerebral artery circle .

本文应用血管色素明胶灌注法，观察了54例成年家兔的大脑动脉环。

The cerebral arterial circles of54 adult rabbits were observed by injection of colorgelatin .

大脑动脉环后交通动脉开放17例19支。

Opening of posterior communicating artery in the circle of Willis happened in 17 cases .

多数兔大脑动脉环虽不具有前交通动脉，但它仍为完整的封闭型环。

Though there was no anterior communicating artery in most of thecerebral arterial circles , they appeared as complete circles .

结果12例动脉瘤均位于大脑动脉环前部；

Results ( 1 ) The 12 cases of aneurysm all located on the anterior part of the circle of Willis .

目的建立人体脑干、三叉神经及大脑动脉环的可视化数字模型。

Objective To establish the digitized visible model of the brain stem , trigeminal nerve and cerebral arterial circle of the first Chinese visible human .

在异网的背内侧部这些吻合支又聚集形成颈内动脉颅内段和后交通动脉自海绵窦传出并互相连接形成大脑动脉环。

By union of these rete branches , the efferent vessels , the internal carotid artery intracranial segment and the caudal communicating artery arose from the carotid rete and divided to form the cerebral arterial circle .

颈内动脉颅内段、大脑中动脉、大脑动脉环、蛛网膜下腔内动脉、软膜内小动脉等各动脉外膜中有碳颗粒，周围不存在内皮。

Carbon particles were also found in the adventitia of arteries , the internal carotid artery internal cranium , the middle cerebral artery , the circle of Willis , the arteries in subarachnoid space , and the arterioles in pia mater .
