Cases · Intracranial Stenosis
The narrowing, or stenosis, of a cerebral artery can cause ischemic stroke. About 8-10% of strokes are caused by stenosis due to atherosclerotic disease of cerebral arteries. Patients may present with transient ischemic attacks, small stroke, neuropsychological deficits, etc.
When an intracranial stenosis is diagnosed as the cause of the patient's symptoms, the first treatment of choice is anticoagulation, however, if the stenosis is severe or resistant to medical therapy, endovascular therapy allows a vascular prosthesis (stent) in the diseased artery to be reopened allowing the normal passage of blood to the brain. This technique is done using an artery in the leg (femoral artery) or arm (radial artery), to reach the cerebral artery stenosis and place the stent.
