If It’s not so severe, then it can be treated only with ANTI-COAGULANT i.e. blood thinner to prevent it from getting bigger of clot or new clot formation. It doesn’t lyse the clot.
These comes in injectable and tablet forms. Your doctor would guide what is best for you.
Some patient cannot take medicine due to side effects or other reason, then an "inferior vena cava filter" (also called an IVC filter) is advised.
If you have very large clot, it will cause blood pressure to fall and body goes in ‘shock’ due to lack of blood supply. In such case doctors can give medicine to dissolve the clot. This “clot-busting" medicine - THROMBOLYSIS, and is given through a catheter (a small tube inserted into the vein). In some cases, doctors will do surgery to remove the clot.
