What is it?
Thrombolysis is also known as thrombolytic therapy and is used to dissolve blood clots, improve blood flow and prevent organ and tissue damage. Medication is delivered to the blood clot through image-guided catheterization or through an intravenous line.
What is it for?
Blood flow to limbs can be blocked if a blood clot forms in artery of the arm of leg. Clots can cause severe pain or be fatal. Thrombolysis dissolves blood clots and restores blood flow.
