If bleeding into the brain happens after TPA is given, it may cause your stroke symptoms to be worse and may result in death. However, the death rate is the same with or without TPA and there is still a greater chance of recovery with TPA treatment. TPA may also cause bleeding in other areas of the body.

How does plasmin break up blood clots?
Plasmin attacks the fibrin filaments, dissolving the net and breaking up the blood clot. Blood clots are broken apart by plasmin as they form. So long as there is sufficient stimulus for blood to clot, clots will form faster than plasmin can break them apart. When the stimulus vanishes, the blood clot eventually breaks apart and disappears.
What is the best medication for ischemic stroke?

When a blood clot is stopping blood flow to the brain, a powerful clot-busting medication called tPA is used to dissolve ...
What happens when a blood clot vanishes?
When the stimulus vanishes, the blood clot eventually breaks apart and disappears. The objective of thrombolytic therapy is to accelerate the removal of a blood clot by enhancing the conversion of inactive plasminogen to clot-busting plasmin.
How to treat blood clots in stroke?
The technique for treating blood clots causing stroke is called intravenous thrombolysis —in lay terms, “clot-busting.” Thrombolysis is the combination of two Greek words, “thrombus,” meaning blood clot, and “lysis,” meaning to dissolve or break apart. The body has a natural mechanism for doing this through proteins that circulate in the blood. One of these is plasminogen, an inactive protein that the body converts to plasmin, an enzyme that breaks apart and dissolves blood clots. To make this conversion, another enzyme called tissue plasminogen activator (tPA) is required.
What is the process of blood clotting?
Blood clotting is a dynamic process. Fibrin filaments act like nets to trap red blood cells and stop the bleeding. As fibrin filaments form, tPA in the serum of the trapped blood begins to adhere to the fibrin, converting plasminogen to plasmin. Plasmin attacks the fibrin filaments, dissolving the net and breaking up the blood clot.
