Some causes of cerebral edema are an large ischemic strokes and meningitis.

脑水肿可能的原因还包括严重脑梗死、脑膜炎。

An ischemic stroke can happen when something blocks one of the blood tubes leading to the brain.

通往大脑的血管被堵住就会引起缺血性中风。

The displaced part of the brain can compress the anterior cerebral artery, and that can cause an ischemic stroke.

大脑移位的部分会压迫大脑前动脉，可导致缺血性脑梗死。

But the more common type is the ischemic stroke, when a clot blocks a vessel and brings blood flow to a halt.

但更常见的类型是缺血性中风，当凝块阻塞血管并导致血流停止时。

The posterior cerebral artery can also be compressed, which results in ischemic stroke of the occipital part of the brain, which is responsible for processing of visual information.

另外，大脑后动脉也会受到压迫，导致大脑枕部缺血性脑梗死；大脑枕部区域本来负责视觉信息的处理。
