Conclusion vascular compression of abducens nerve root in cisternal segment might cause abducens nerve paralysis .
结论脑池段展神经受血管压迫可导致展神经麻痹。
There is no value in fixing location of diagnosis of abducens nerve paralysis .
单纯的外展神经麻痹并无定位诊断价值。
The inferior cavernous sinus artery is an important landmark to seek for the abducens nerve and sympathetic nerve .
海绵窦下动脉是寻找海绵窦段展神经与交感神经的一个重要标志。
Conclusion : many multiplicity and complicated causes can lead to abducens nerve paralysis .
结论：外展神经麻痹病因多样且复杂。
In cisternal segment , the ventral surface of the abducens nerve root was crossed by the anterior inferior cerebellar artery ( aica ) , posterior inferior cerebellar artery , inferolateral pontine artery ( ilpa ) , while the dorsal surface of the abducens nerve root was crossed by the aica and ilpa .
