APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -A stroke, sometimes call a brain attack, happens in one of two ways: A blocked artery or a ruptured artery. 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.

Detailed explanation-2: -Do blood clots play a role in these conditions? Blood clots are the root of both aneurysms and embolisms in some form. An aneurysm can be caused by a plaque, or thrombus, that forms in a blood vessel, weakening the vessel wall and leading to rupture.

Detailed explanation-3: -An aneurysm can cause an ischemic stroke, because the blood coming out of the burst blood vessel can irritate the arteries, causing them to spasm.

Detailed explanation-4: -Ischaemic strokes are the most common type of stroke. They happen when a blood clot blocks the flow of blood and oxygen to the brain. These blood clots typically form in areas where the arteries have been narrowed or blocked over time by fatty deposits (plaques).
