When the brain is hungry of oxygen, cell, and tissue starts to damage in a matter of minutes. However it is possible to reverse the damage of the brain to some extent or in full, by mechanical thrombectomy. Put simply, mechanical thrombectomy used to treat brain stroke by dispelling the clot that causes the clogging of the arteries carrying blood to the brain.In clinical terms, mechanical thrombectomy provided to the patients suffering from acute ischemic stroke i.e. brain stroke patients whose brain lacking blood flow. This is natural because the blood vessels to the brain narrows down over time due to fats or plaque deposits. This is the reason patients with levels of cholesterol are suggested to get their screening done on a regular basis for clogs. The build-up, also known as clot, can block the blood vessels in part or in full, decreasing normal blood flow to a vessel or blocking flow of blood entirely. CT or MRI Imaging scans can help in estimating the blockage so that a physician can suggest whether the patient is able to use mechanical thrombectomy as a recourse for treatment. Mechanical thrombectomy has to be carried out within the golden period which is 6 hours from the last known normal cases in 24 hours. This process proposes stenting or re-opening and re-establishment of normal flow of blood through the cranial arteries.
