APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -A stroke, sometimes called a brain attack, occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts. In either case, parts of the brain become damaged or die. A stroke can cause lasting brain damage, long-term disability, or even death.

Detailed explanation-2: -An ischemic stroke occurs when a blood vessel that supplies the brain becomes blocked or “clogged” and impairs blood flow to part of the brain. The brain cells and tissues begin to die within minutes from lack of oxygen and nutrients. Ischemic strokes are further divided into 2 groups: Thrombotic strokes.

Detailed explanation-3: -Arterial thrombosis can cause a stroke if a blood clot is blocking an artery that supplies blood to your brain. The symptoms of a stroke can come on suddenly and may include: numbness or weakness down one side, ranging in severity from weakness in your hand to complete paralysis of the whole side of your body.
