thrombusból

A thrombus is a blood clot that forms within a blood vessel, such as an artery or a vein. It originates from a disruption in the normal process of blood coagulation, which is the body's mechanism for stopping bleeding. This can occur due to factors like damage to the vessel wall, slow blood flow, or changes in the blood's composition that make it more prone to clotting.

When a thrombus forms, it can partially or completely block the flow of blood through the vessel. If the thrombus breaks away from its attachment point and travels through the bloodstream, it becomes an embolus. This traveling clot can then lodge in a smaller blood vessel, obstructing blood flow to vital organs.

The consequences of a thrombus depend on its location. A thrombus in an artery supplying the heart can lead to a heart attack (myocardial infarction), while one in an artery supplying the brain can cause a stroke. In veins, thrombi, often referred to as deep vein thrombosis (DVT), can cause pain, swelling, and redness, and if an embolus breaks off and travels to the lungs, it can result in a pulmonary embolism, a life-threatening condition. Treatment for thrombosis typically involves anticoagulant medications to prevent further clot formation and, in some cases, clot-dissolving drugs or surgical procedures to remove existing clots.
