Ischemic Stroke

An ischemic stroke occurs when there is sudden loss of blood flow to the brain caused by blockage of artery or a temporary loss of blood supply to one part of the brain (mini-stroke). Ischemic stroke can be caused by either thrombosis or embolism. Thrombosis is obstruction of blood flow in the blood vessel due to formation of clot. Embolism occurs when a particle which can be a broken piece of thrombus, fat, air bubble or a tumor flows in the blood and reaches brain until it gets stuck in a narrow blood vessel through which it cannot pass and restricts the blood flow. This interruption of blood flow deprives the brain of oxygen which results in irreversible brain injury and disability.
