Nutrient arteries of the abducent nerve root mainly came from anterolateral pontine perforating artery, anterior inferior cerebellar artery and inferior lateral pontine artery.

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.

Results Pontine basal infarction was a common infarction in the posterior circulatory system. The pathogenic mechanisms were mainly basilar artery branch disease (BABD) and small artery disease.
