Within the field of medicine, a medical emergency that occurs when the blood flow that is responsible for irrigating the brain is stopped. In just a few minutes, brain cells begin to die. Strokes can be of two types, the most common type, cerebral ischemic attack, when a clot of blood blocking a vessel blood in the brain, on the other hand is known as hemorrhagic stroke, to which is caused by the rupture of a blood vessel that carries blood into the brain. On the other hand, the "mini-strokes" or transient ischemic attacks, occur when the blood supply to the brain is interrupted for a period ofshort time.
It is important to note that stroke is one of the leading causes of disability and death around the world. Annually, nearly 800,000 Americans are affected by strokes; and about 137,000 of them die from this cause, while the lives of the rest of those who survive change completely for the rest of their lives.
As mentioned above, strokes can be of several types, among which the following stand out:
- Ischemic strokes: these are caused by an arterial obstruction, it is the most frequent of all since approximately 85% of strokes are of this type. Despite the exhaustive analyzes carried out in each case, the causes of many spills of this type are still unknown. However, a series of preventive treatments have been created that are highly effective for all types of ischemic stroke. This type of spill at the same time is subdivided into:
- Thrombotic effusion: called that way because a blood clot is formed, which is known as a thrombus in an artery in the neck or brain, usually due to an accumulation of fat in those arteries.
- Embolic effusion: is when the obstruction occurs due to blood clots that form in other regions of the body such as the heart and travel to the brain.
