How does tPA cause hemorrhage?
The risk of hemorrhage is increased because tPA triggers plasmin activation, which degrades cross-linked fibrin into fibrin split products and reversal agents. Reperfusion injury and breakdown of the blood-brain barrier may also contribute to the risk of symptomatic intracranial hemorrhage.
