Thrombosis occurs when blood clots (gel-like clumps of blood) block your blood vessels. Normally, blood clots help plug an injured blood vessel. When blood vessels are plugged unnecessarily by a blood clot, it’s considered thrombosis.
There are two types of thrombosis. Venous thrombosis is when the blood clot blocks a vein (blood vessels that carry blood to the heart). Arterial thrombosis is when the blood clot blocks an artery (blood vessels that carry blood away from the heart).
While arterial thrombosis can be life threatening, most patients quickly recover from an episode of venous thrombosis and learn how to manage the risk of future reoccurrence.
Deep vein thrombosis (DVT) can also be life threatening. Once stabilized, the long-term goal is to manage the risk of recurrence.
