The purpose of cerebral revascularization is to bring more blood to areas of brain ischemia. Ischemia is a condition where the flow of oxygen-rich blood to a part of the body
is restricted. The types of revascularization are "therapeutic revascularization" for emergent cases, and "preventive revascularization" which are elective cases.
Indications for revascularization are:
Cerebral ischemia, chronic and intractable
Cerebral ischemia, progressive
Inoperable (surgical-endovascular) aneurysms
Skull base tumors
