What percentage of arteries that are opened by thrombolytic therapy will later close again?

When considering the effectiveness of thrombolytic therapy, it is important to recognize that while this treatment can successfully open occluded arteries, there is still a significant chance of reocclusion. Evidence from clinical studies indicates that approximately 15% of the arteries that are reopened following thrombolytic therapy may ultimately close again. This percentage reflects factors such as the underlying condition of the arteries, the presence of advanced atherosclerosis, and the timing of intervention.

Understanding this rate of reocclusion is critical for managing patient care post-thrombolytic therapy, as it informs the decision-making process regarding subsequent treatments, preventative strategies, and the monitoring of patients. Strategies such as the use of antiplatelet agents may be considered to help maintain arterial patency after thrombolytic therapy.
