A Stroke occurs when blood vessels in the brain get rupture and bleed or when there is a blockage in the blood supply to the brain due to plaque. Ischemic stroke occurs when there is restricted blood flow to the brain due to vascular stenosis or insufficient oxygen supply. Hemorrhagic stroke occurs when there is a rupture of a blood vessel which leads to accumulation of blood in the brain. Ischemic stroke ranges from mild (Transient ischemic stroke) to severe (severe ischemic stroke). Ischemic stroke is diagnosed by physical examination, various blood tests, Computed tomography scan, Magnetic resonance imaging scan, Carotid Ultrasound, Cerebral angiogram, Echocardiogram and can also be done by using new techniques such as cone beam imaging, cerebrotech stroke detecting visor. The first step for treating the ischemic stroke is an emergency response which can be done by tissue plasminogen activator and mechanical thrombectomy. Secondary treatment includes Carotid artery stenosis, Carotid endarterectomy, Carotid artery stenting and it can also be treated by some new techniques such as vivistim nerve stimulation treatment and cerenovus aneurysm device. Relevant treatment of ischemic stroke is essential in the reduction of mortality and morbidity. |
