Prevention of Stroke
Stroke, also called as ‘Brain Attack’, occurs due to loss of blood flow to the brain. When the loss of blood supply is for a prolonged period, it can lead to permanent neurological damage or death. Many a time, fatty substancesline the inner wall of the blood vessels forming a plaque, thus narrowing the artery and reducing flow of blood to the brain. This is called the Carotid Artery disease, and is one of the primary causes for Stroke.
Some patients can have no symptoms related to narrowing of the carotid artery, while others can have symptoms like:
- Temporary weakness, numbness, tingling of an arm, leg or face on one side of the body
- Sudden blurring or loss of vision in one eye
- Slurring of speech
- Confusion, fainting, or temporary loss of consciousness
These symptoms may last for just a few minutes, or some hours; but should never be ignored.
Patients over the age of 50 years, are diabetic and smokers need to be screened for narrowing of the carotid artery. This can be done by ultrasound – colourdoppler. Early diagnosis can help in modifying risk factors and starting treatment.
Carotid Artery Angioplasty Treatment
Prevention of stroke takes high precedence as it can cause irreversible neurological damage. This is possible by medical intervention as well as lifestyle changes to keep fit and reduce cholesterol. Medical intervention in prevention of stroke is decided after conducting multiple tests,by way of vascular surgery or carotid angioplasty. Carotid angioplasty, also called as Carotid stenting is a non-surgical and minimally invasive procedure.
Carotid Artery Stenting
Carotid stenting is a contemporary treatment method. This minimally invasive procedure is performed in a catheterization laboratory by an Interventional Radiologist (IR). In the carotid stenting procedure, a stent (a small mesh tube) is introduced in thediseased/narrowed portion of the artery under local anaesthesia, and gently expanded to open up the blood vessel. A Filter device is placed distally to capture dislodged plaque fragments.Dr. Saurabh Joshi, the chief Interventional Radiologist of the Vein Center,is experienced in carotid angioplastyprocedures inMumbai.
Carotid Endarterectomyis thevascular surgeryperformed to treat patients with carotid atherosclerosis or mild strokes. An incision is made in the neck at the carotid artery. The plaque and diseased portions are surgically removed; then re-sewn back together to allow improved blood flow to the brain. This method of treatment is a full-fledged surgical procedure and requires hospitalization.
⇒Most of the patients can go home the day after thecarotid stenting/angioplasty procedure, as it is not a vascular surgery.
⇒Apart from these, other vascular treatments are also conducted as day care procedures at the Vein Center, the super specialty clinic for carotid stenting/angioplasty in Mumbai.
