Acute ischemic stroke can be defined as loss of function in certain parts of brain due to lack or disturbance in the blood supply to the brain. This is usually caused by atherosclerosis plaques blocking blood vessels, narrowing of blood vessels, or blood clots closing off blood supply to or from arteries feeding the brain. Technological advancements in surgical devices coupled with rising prevalence of acute ischemia stroke cases collectively accentuates the global demand of surgical procedures in acute stroke treatment. Similarly, aging population, increased demand for minimally invasive procedures and rise in healthcare spending has triggered the growth of this segment market.
