When a stubborn blood clot forms, thrombolysis offers a direct, non-surgical way to dissolve it. Instead of a major operation, doctors deliver clot-busting medication straight into the blocked vessel.
Common Indications for Thrombolysis
Your doctor may request this procedure if you have:
- A severe deep vein thrombosis (DVT) in your leg or arm.
- A blockage in an artery cutting off blood supply to a limb.
- A clotted dialysis fistula or graft.
What exactly does it do?
It melts away the blockage to restore healthy blood flow, helping to prevent permanent tissue damage and severe swelling.
What happens during the procedure?
The doctor numbs your skin and uses ultrasound or X-rays to guide a thin tube (catheter) into the affected blood vessel. The tube then drips medicine right into the clot. Sometimes, the tube stays in place for a day or two while the medicine slowly does its work. During this time, you will stay in the hospital for careful monitoring.
Do I need to prepare?
Yes, you will likely need to fast before the procedure. You may be asked to avoid solid food from midnight, though clear liquids are usually allowed until a few hours before.
How long does it take?
The initial placement takes about an hour. However, the medicine may run for several hours or up to 2 to 3 days to fully dissolve the clot.
Will it be painful?
The procedure itself is quite comfortable. You will feel a small pinch for the numbing medicine, and you will receive relaxing medication through an IV. If the clot was causing severe pain, you will likely feel significant relief as it clears.
Conclusion
Thrombolysis is an excellent method for restoring circulation without surgical cuts, preserving your veins and arteries from lasting damage.
