A stroke occurs when blood supply to a part of the brain is reduced or completely stopped. Ischaemic stroke is the most common type of stroke and it caused by narrowing or blockage of blood vessels by fatty deposits, blood clots or other debris.
It is a medical emergency and timely, prompt treatment can reduce brain damage and complications.
Recanalization of the occluded vessel may be performed if patient presents within the golden window period (six hours to 24 hours) to the hospital equipped with neurointerventional facility. The key is to ACT FAST. Look at F A C E, A R M S, S P E E C H & T I M E.
Broadly, the signs and symptoms include slurring of speech, paralysis or numbness in one or more limbs or face, vision problems, trouble in walking. After a physical examination by a doctor, the diagnosis of stroke is made by one of the brain imaging tests like a CT Scan/MRI.
The treatment of an ischaemic stroke includes administering an emergency intravenous medicine which tries to break up the clot which has to be given within 4.5 hours of first appearance of symptoms and in case of large vessel occlusion, Emergency endovascular thrombectomy is performed to pull out the clots from the arteries of the brain. This procedure involves taking a device called Stentrievers into the occluded artery. Once the clot is caught by the stent, the entire apparatus with the clot is removed from the body out through a small puncture in the femoral artery at the groin.
