What is vascular stenosis?
Vascular stenosis is a term used to describe the narrowing of the blood vessels. Most often the narrowing of the blood vessels occurs due to atherosclerosis inside the arteries, blood vessels that carry blood from the heart to supply the body. Atherosclerosis or hardening of the arteries is a process in which fat, cells and other substances create an artery inside the walls that form what is called plaques. These atheromatous plaques increase the walls of arteries heavier and stronger, so the blood vessel becomes narrower and less flexible, making blood flowing more difficult. Vascular stenosis usually affects arteries in the brain, heart and legs, and if it is difficult, it causes tissue death, resulting in conditions such as moves and heart attacks. This can lead to a state known as interrupted Claudication, where in the early stages of tensioning a walk at a certain distance, ping pain is felt in calves. The pain disappears after a few minutes of rest. If the disease progresses, the pain occurs even at the rest and ulcers of the legs or even gangrene of the fingers and feet.
Vascular arterial stenosis in the heart can lead to a condition called angina, where chest pain is experienced during exercise. Again, rest usually causes pain to disappear in a short time, even if there is potential to completely block the artery. In this case, the pain becomes severe and persistent, perhaps spreading into the arm or neck and a heart attack in which the heart muscle area dies.
When the arteries in the brain are affected by vascular stenosis, it can turn off the blood supply to a part of the brain tissue or lead to a small blood vessel, while bleeding to B into bdéštěště. Any of these events results in a stroke where the area of brain tissue dies, causing a number of possible symptoms, including paralysis, insensitivity and speech problems, vision, movement and balance. The carotid artery stenosis, which narrows large arteries in the throat, can also reduce the blood supply and lead to a stroke.
If vascular stenosis withTANA is sufficiently serious to cause a stroke or heart attack, emergency treatment in the hospital. Prevention is important and stenosis progression can be stopped and the outlook has improved by stopping smoking, weight loss, healthier food and more exercise. Medicines are available for treating conditions such as angina and intermittent claudication, and surgery is sometimes used to circumvent or expand blocked arteries. It is also beneficial to treat any other conditions that tend to worsen vascular stenosis such as high blood pressure and diabetes.
