Thrombus

Clot; Emboli; Thrombi

Thrombi and emboli can firmly attach to a blood vessel. They can partially or completely block the flow of blood in that vessel.

A blockage in the blood vessel prevents normal blood flow and oxygen from reaching the tissues in that location. This is called ischemia. If ischemia is not treated promptly, it can result in tissue damage, or death of the tissues in that area.
