Sudden onset of occlusion of brain vessel known as stroke.
Occur in 3 % of ischemic strokes in patients below 40 age. 10 in 1 lakh population between 35 to 44 years of age.
Over 10 % of ischemic strokes occur in patients below 55 age. 73 in 1 lakh population below 55 age. When the brain doesn’t get blood supply, the brain tissue will die which is known as ischemia of brain parenchyma. When a large ischemic event takes place, it’s known as an infarct.
When a patient has an infarct of part of the brain, that part of the brain stops its function. Patients who reach the hospital in time ( within 4 hours ) will have an Angiography of the brain, and they may be advised for thrombolysis or mechanical thrombectomy according to the patient’s angiographic findings. The majority of the patients who reach in time will recover very well due to fast intervention. Some of the patients who come lately may have haemorrhagic transformation ( bleeding ) at the impact area and they may require surgical removal of brain haemorrhage by endoscope or craniotomy. Some of the patients may develop malignant infarct and may require decompressive craniectomy to relieve brain pressure.
