What causes restricted blood flow to the brain?
Restrictions in blood flow may occur from vessel narrowing (stenosis), clot formation (thrombosis), blockage (embolism) or blood vessel rupture (hemorrhage). Lack of sufficient blood flow (ischemia) affects brain tissue and may cause a stroke.
What can cause blockages in the brain?
The narrowing is caused by a buildup and hardening of fatty deposits called plaque. This process is known as atherosclerosis. A stroke occurs when plaque causes the artery to become blocked and that area of the brain is deprived of blood, which damages and kills nerves in the brain.

What is the surgical method for thrombus removal?
In the event that drug therapy and physiotherapy are ineffective, a surgical method is used. It is aimed at the mechanical elimination of thrombus and the limitation of the affected area from the total blood flow (endarterectomy). Also, the surgical method can be aimed at improving blood flow. A common type of surgical intervention is angioplasty, during which a special stent is inserted into the basilar artery, preventing the narrowing of the arteries lumen. This helps normalize blood circulation.

What is the basilar artery?
The basilar artery is a vital vessel contributing to the posterior cerebral circulation. It is formed at the junction of the pons and medulla by the convergence of the dual vertebral arteries. The vertebral arteries join the basilar artery to form the vertebrobasilar system, which supplies blood to the posterior portion of the circle of Willis.

What causes a vascular dissection in the basilar artery?
The cause can occur from thromboembolism , atherosclerotic disease , or vascular dissection. The mechanism differs depending on the affected segment. The atherosclerotic disease more commonly affects the mid-portion of the basilar artery, followed by the vertebrobasilar junction. Lodging of an embolic source is much more frequent in the distal third of the basilar artery especially at the top of the basilar artery and the vertebrobasilar junction. Arterial dissection is more common in the extracranial vertebral artery and has been associated with neck injuries and cervical chiropractic adjustments. Intracranial dissections are exceedingly rare. [1]
