Posterior communicating artery. In human anatomy, the left and right posterior communicating arteries are arteries at the base of the brain that form part of the circle of Willis.

A cerebral infarction is a type of ischemic stroke resulting from a blockage in the blood vessels supplying blood to the brain. It can be atherothrombotic or embolic.Stroke caused by cerebral infarction should be distinguished from two other kinds of stroke: cerebral hemorrhage and subarachnoid hemorrhage.A cerebral infarction occurs when a blood vessel that supplies a part of the brain becomes blocked or leakage occurs outside the vessel walls.This loss of blood supply results in the death of that area of tissue. Cerebral infarctions vary in their severity with one third of the cases resulting in death. cerebral infarction occurs when a blood vessel that supplies a part of the brain becomes blocked or leakage occurs outside the vessel walls.
