Close to 1.2 million people in India suffer from stroke. Dr Bheem Sangars, a Vascular Surgeon at Global Hospitals speaks about the surgery to reduce the risk to stroke
 
 
1. What causes stroke?
 
Out of the various causes, narrowing of Carotid artery is one of the main and treatable causes.Carotid arteries are the main blood supply to the brain.
 
 
2. What are the symptoms of stroke?
 
Sudden loss of sensation and/or function in one of the limbs, sudden loss of speech or sudden loss of vision in one eye with typical description of curtain coming in front of the eye.
 
 
3. What should one do when one observes such symptoms?
 
If these symptoms are noticed, one should quickly consult a specialist and should have a scan to see how much their Carotid arteries are narrowed along with investigations for other causes of the problem. The scans will clarify what is the status of their Carotid arteries, the degree of narrowing and any irregularity in lining and fresh blood clots sitting in that area – all the above findings are very important to know as the situation needs urgent further investigations and management. When the carotid artery is narrowed more than 50 to 70% and the inside lining is very irregular with fresh blood clots, sometimes clearly seen on various modalities of investigations, there is a very high chance that they will have another serious episode of stroke which can be prevented.
 
 
4. What is the treatment?
 
Carotid Endarterectomy. It is removing the damaged lining inside the carotid artery and repairing it. It is a well-established treatment. These operations are done by highly specialized vascular surgeons and need a detailed discussion of the need of the procedure, possible outcomes and risks and benefits. There are no well established, equally effective and durable alternatives when the Carotid arteries are severely narrowed. Some specialist proposes inserting a Stent (a metal spring) inside the artery and widening it.
Carotid surgery generally takes approximately three hours and sometimes can be done with local anesthetic medicine while the patient is awake. Generally, the patients can be discharged in two days.
