Is cerebral infarction posterior circulation ischemia?

Cerebral infarction is a kind of ischemic cerebrovascular disease, but not entirely due to the cause of posterior circulation ischemia, because in different parts of the brain, there may be cerebral vascular blockage, so there will be ischemic damage to brain tissue, all called cerebral infarction. There are cerebral thrombosis and cerebral embolism, but the causes of vascular blockage are different. In the early stage, thrombolytic and anticoagulant drugs are needed to treat and dredge the blood vessels in the brain as soon as possible. In the later stage, after the disease stabilizes, if dysfunction occurs due to brain tissue damage, systematic rehabilitation treatment is needed as soon as possible.
