“A stroke is a medical emergency that needs immediate medical attention because the brain does not receive enough oxygen or nutrients, causing brain cells to die. How a person is affected by their stroke depends on where the stroke occurs in the brain and how much the brain is damaged,” informed Dr Sandeep Sharma,Senior Consultant and Head, Neuro-interventional Radiology from Fortis Hospital, Mohali. Two recent stroke cases reported at the hospital were successfully treated.
“A stroke also called as a ‘brain attack’, occurs when the blood flow to an area in the brain is blocked. There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding,” informed Dr. Sharma. He further informed that in the hemorrhagic stroke, there is a brain aneurysm burst or a weakened blood vessel leak (hemorrhagic), which is one of the two types of stroke. While it is the least common of the two types of stroke; it most often results in death. Whereas, an ischemic stroke is one in which the blood vessel carrying blood to the brain is blocked by a blood clot (ischemic).
Giving details about cases, Dr Sandeep Sharma said, Mr Ram Nath, 50 years old came to the hospital with complaints of severe headache, followed by loss of consciousness. He had an earlier history of seizure. ‘’Patient had a very big brain artery balloon like swelling rupture a day before. He went from one hospital to the other but his case was complicated due to large size of aneurysm and Endovascular coiling was performed. He underwent the procedure same day and was discharged within two days”, added Dr. Sharma.
Citing another case, Dr Sharma said, “A 57 year-old patient was brought to emergency with complaints of high grade fever and vomiting. They came to the hospital after 10 hours had lapsed and Mechanical Thrombectomy was done. His totally paralyzed body was improving and he was discharged within 5 days. Now he does not have significant paralysis and is under preventive care and regular OPD care’’ explained Dr Sandeep.
The best way to prevent a stroke is through lifestyle changes, including eating a healthy diet, maintaining a healthy weight, exercising regularly, not smoking tobacco, avoiding alcohol, keeping blood pressure under control, managing diabetes and treating conditions like obstructive sleep apnea.
A recent study says, “Around 82% stroke patients reached a hospital providing tertiary care after six hours of the onset of a stroke. Around 12% patients reached the hospital between three-and-a-half and six hours, and only 5% patients reached within three-and-a-half hours.”
