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。

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 .

脑池段展神经根腹面有小脑前下动脉、小脑后下动脉、脑桥下外侧动脉跨过，展神经根背面有小脑前下动脉、脑桥下外侧动脉跨过。
