Results All of the aneurysms developed at the takeoff point of perforating arteries, the recurrent artery of Heubner in three cases, the medial proximal lenticulostriate artery in five cases.

结果所有动脉瘤均位于A1穿动脉的起始部，起源于内侧远端纹状体动脉的3例，内侧近端纹状体动脉的5例。

The internal carotid artery upper space could use as operating space in 7 patients because of absence of the lenticulostriate arteries and the perforating artery of A1 and bifurcation of internal carotid artery.

颈内动脉上间隙均见不同程度增大。7例由于A1及分叉部穿通动脉、M1内侧豆纹动脉缺如形成自然手术间隙进行直接操作。

Conclusions Pontine infarctions, which mainly located in mid-upper paramedian pons, are usually due to vertebrobasilar artery stenosis and occlusion of pontine perforating arteries by hypertension.

结论脑桥梗死多发生在脑桥中上部的旁正中区域，主要由椎基底动脉狭窄、高血压性基底动脉穿通支闭塞所致。

11 sides' middle cerebral arteries had medial lenticulostriate artery, short course and overlapped with another perforating arteries when entering the anterior perforated substance. 4 sides medial lenticulostriate artery coincided with perforating arteries in A1.

11侧大脑中动脉存在内侧豆纹动脉，行程短，进入前穿质时与其他穿通动脉存在重叠，4侧内侧豆纹动脉与A1段穿通动脉间存在吻合现象。
