After thrombolysis is complete your doctor will reassess your symptoms and may check with further imaging studies (e.g. CT scan, echocardiogram, arteriogram or venogram) whether there is residual blood clot.
Most of the time thrombolysis will reverse or alleviate the symptoms.
Depending on the underlying cause of clot formation your doctor may suggest further treatment that may include open surgery or some kind of minimally invasive intervention (e.g. balloon dilatation or stent placement at a narrow hardened (atherosclerotic) artery).
You will eventually be placed on blood thinners (anticoagulants), initially heparin and then warfarin (Coumadin).
Thrombolytic therapy is not always successful and the treatment may not dissolve the blood clot, particularly if initiation of treatment has been delayed.
Other times even if the clot has dissolved the affected tissues (heart, brain, lungs or leg) may have permanent damages because of the prolonged restriction of blood flow.
Some other patients with successful clot dissolution may redevelop the clot in the same blood vessel.
In all these cases more aggressive treatment will be needed to address the underlying causes of the blood clot and repair damaged tissues and organs.
