Carotid angioplasty/ stenting

Carotid angioplasty/ stenting

A disease that affects the blood vessels leading to the head and brain is called a Carotid artery disease. Just the same way as heart, the brain’s cells are in a need of constant supply of oxygen-rich blood, which is also known as Oxygenated blood. Two large carotid arteries in the front of your neck and by 2 smaller vertebral arteries at the back of your neck help to meet this blood supply to the brain. At the base of the brain to form what is called the basilar artery the right and left vertebral arteries come together. When the carotid arteries become blocked and the brain does not get enough oxygen a stroke most often occurs.

The risk of stroke is increased because Carotid artery disease in 3 ways:

What is carotid artery angioplasty?

Carotid artery angioplasty is done either by Interventional neurosurgeon or endovascular surgeons in order to open the clogged arteries in the patient’s neck to prevent or to treat a stroke. A long, thin tube called a catheter that has a small balloon on its tip is used. The balloon is inflated at the blockage site in the carotid artery so that the plaque can be flattened or compressed against the artery wall.

With the placement of a small, metal, mesh-like device called a stent carotid angioplasty is often combined. When placed inside of a carotid artery, a stent acts as a support. So that the artery remains the artery opened. Therefore the stent helps to improve blood flow to the brain by keeping the carotid artery open. Vascular stenting are minimally invasive procedures performed to improve blood flow in the body’s arteries.

How is Carotid Angioplasty Performed?

To perform an angioplasty, an interventional neurosurgeon makes a small nick in the skin and inserts a balloon-tipped catheter, a thin, plastic tube. The catheter is threaded through the artery until it reaches the site of the blockage, where the balloon is inflated, then deflated and removed. Expanding the balloon helps to restore blood flow by stretching the arterial wall, which increases the inner diameter of the artery.

Many angioplasty procedures also include the placement of a stent, a small, flexible tube made of metal to support the damaged artery walls. Stents are typically placed over a balloon-tipped catheter, which is expanded, pushing the stent in place against the artery wall. When the balloon is deflated and removed, the stent remains permanently in place, acting like a scaffold for the artery.

What are Some Common Uses of the Carotid Angioplasty?

Angioplasty is used to treat when arteries all over the body have narrowed or blocked, including:
