Intracranial atherosclerosis or ICAD is the hardening of arteries which become clogged with a sticky substance called plaque. These blood vessels supply blood to brain and the blockage with plaque limits blood flow causing a heart attack. If the vessel becomes completely blocked, the insufficient blood flow to brain results into stroke.
There are no usual symptoms of this neurovascular disorder ICAD and can only be diagnosed if you had a stroke. The chances of ICAD increases with certain health conditions such as diabetes, heart disease, obesity, high blood pressure or high cholesterol or a family history of stroke.

For ICAD, the doctor may recommend medication and lifestyle changes to decrease the risk of a stroke. However, if there is significant blockage in the artery, you may need one of the following intracranial atherosclerosis treatment:
Intracranial Stent Placement and Angioplasty Intracranial stent placement is an endovascular process in which a small puncture is made in the femoral artery under local anaesthesia. The catheter is inserted in the internal carotid artery under x-ray guidance which is then negotiated by small caliber wire. The stent is then placed in the narrow area in the artery within the brain and then it is released and dilated with an angioplasty balloon.The stent remains in place and keeps the artery open and improves blood flow.It also holds the plaque and reduces the risk of plaque break off and thus reduces the chances of stroke.
