Сердце и сосуды: Тромбоэмболия
Normal blood clotting seals blood vessels damaged by an injury to help stop blood loss, but sometimes blood clots block blood and oxygen from flowing through a blood vessel. An embolus is a blood clot that breaks off, travels through the blood stream, gets stuck in a smaller blood vessel and blocks the blood supply. A thrombus is a blood clot that partially or completely blocks the vein or the artery. Blood clots may form more easily if your blood flows very slowly through your veins due to inactivity, heart disease or problems with your veins. Smoking and some medicines also increase your risk.
