What is Carotid Artery disease Treatment?
Carotid artery disease treatment is useful in restoring a clogged carotid artery. This treatment is also helpful in treating a stroke condition and works by restoring the decreased (or no) blood supply in the damaged carotid artery.
The carotid artery is one of the two arteries located on both sides of the neck. It is the main artery which supplies blood to the brain. A blockage in one of these arteries can result in a lack of sufficient blood supply to the brain which can give rise to various complications, including stroke and even death.
Carotid artery disease treatment now is performed using a minimally invasive surgical method, called carotid angioplasty. This is performed in order to enlarge the artery and help restore the blood supply to it. This surgery is mostly accompanied by an additional procedure which involves implanting a small metal stent (mesh-coil) in the affected artery to help it to retain the normal width. This helps in keeping the treated carotid artery enlarged and also helps in avoiding the chances of another blockage occurring in the artery in the future.
When is the need for Carotid Artery Disease Treatment?
A carotid angioplasty and stenting procedure is considered effective stroke treatment method as well as adequate stroke prevention technique, if:
- The carotid artery is blocked more than 70% and if the patient has had a stroke (stroke-like symptoms) and is not in a sufficiently healthy condition to undergo a surgical treatment.
- There was an earlier carotid endarterectomy surgery yet the pain is still present, mainly due to the re-stenosis (narrowing) of arteries after surgery.
- The repeated narrowing (re-stenosis) is located in a difficult-to-access location and cannot be treated by using an endarterectomy procedure.
What are the Risks Associated With Carotid Artery Disease Treatment?
As can be seen in any type of major surgery the carotid angioplasty and stenting procedure also may involve certain uncommonly seen risks, such as:
- Stroke/mini-stroke – During the procedure, any blood clots that may form on the catheters might break loose and travel to the brain through the carotid artery itself. Blood thinners are used during the procedure in order to prevent blood clots. A stroke might also occur when the plaques inside the artery get dislodged as the catheters are threaded through the arteries.
- Re-stenosis – This condition is seen when the treated artery starts getting narrowed again (re-stenosis). Stents are used in avoiding this complication.
- Blood clots – Blood clots may form within the stents after a few weeks (or even months) from an angioplasty procedure. These clots increase the risk of causing a stroke or, even, death. Blood thinners are regularly used to prevent this situation.
- Bleeding – Bleeding may be experienced at the incision site but it usually stops on its own after some time.
What is the Carotid Artery Disease Treatment procedure?
Carotid angioplasty is a minimally invasive surgical procedure which uses a system of small flexible tubes (catheters) to perform the required tasks during the surgery. The incisions needed for this surgery are very few (2-4) and very small (keyhole) in comparison to the conventional open-type of carotid artery disease treatment method.
The surgeon will generally administer local anesthesia to numb the incision area and make the required incisions on the artery, which is mostly the femoral artery in the groin region.
Next, the surgeon will require inserting a tubular sheath into the artery and holding it in place. This entry port is used to insert a catheter into the carotid artery, all the while guiding it using advanced x-ray imaging guidance technology.
A contrast substance is then injected into the affected carotid artery using the catheter. This helps in providing a clearer view of the narrowed artery and the cause of the decreasing blood supply to the brain.
The surgeon then fits an umbrella-shaped filter (embolic protection device) in the artery beyond the narrowed portion. This device is helpful in catching any type of debris that may get dislodged from the narrowed portion of the artery during the surgical procedure.
The surgeon will then use another similar catheter (this time with a deflated surgical balloon at the end) by inserting it into the artery till it reaches the narrowed point of the carotid artery. After the surgeon is satisfied that the balloon is placed as planned, he will slowly start to inflate and deflate the balloon a few times. This helps to widen the narrowed portion of the artery in a gradual way.
After the narrowed artery is significantly widened, the surgeon will fix a small metal-mesh tube called a ‘stent’ in the newly-widened portion of the artery. The expanding stent provides support as well as stabilizing the artery walls from collapsing and getting narrowed again (re-stenosis).
Once the stent is firmly fixed the surgeon will carefully remove the catheter as well as the tubular sheath from the incision in the groin region and close the incision using very fine sutures.
Carotid angioplasty with stenting has been proven as an ideal treatment method for narrowed carotid artery disease as well as preventing stroke and other stroke-related complications.
