Carotid angioplasty is a minimally invasive surgical procedure that aims at restoring the flow of blood in the clogged arteries, to ensure normal blood supply to the brain. The procedure is usually performed to elevate the risks of stroke in patients who lie in the high-risk category. The carotid artery is present in a quite tricky position, on either side of the neck and serve as the primary passage for the blood flowing towards the brain. If these get clogged or obstructed, it can disrupt the supply of oxygenated blood to the brain, resulting in a stroke. Carotid Angioplasty involves the use of a catheter and a balloon to address the problem.
Indications
Carotid angioplasty is usually performed for treating stroke or alleviating the risks of same in high-risk patients. Major indications of the procedure include:
- Carotid artery blockage of 70 per cent or more.
- Restenosis post carotid endarterectomy
- Stenosis that cannot be treated with endarterectomy
Procedure
- Carotid angioplasty is a minimally invasive procedure which means that is carried out via a small surgical cut
- The procedure is performed under the influence of anaesthesia such that you do not feel any pain or discomfort
- Once you are under the influence of sedatives small incision will be made near your client to insert the catheter fitted with a balloon on one of its ends.
- The catheter is carefully guided towards the affected artery using detailed imaging guidance.
- Once the catheter is in position the balloon is inflated to force open the clogged walls of the arteries and treat the obstruction.
- A stent may be placed inside the affected artery to prevent it from narrowing back in future.
- Once the blockage has been cleared and the blood flow has been restored, the capacitor is removed along with the balloon and then the season is closed.
