[Research progress of thrombolytic therapy for high risk and intermediate-high risk pulmonary thromboembolism]

Acute pulmonary thromboembolism (PTE) is a highly fatal disease. Fibrinolytic therapy can rapidly improve pulmonary hemodynamics and is an important life-saving treatment. How to screen patients who may benefit from thrombolytic therapy and how to reduce the complications of major bleeding are still the focus of PTE treatment. In addition, as our understanding of post-PE syndrome (PPES) has improved, much attention has been paid to whether thrombolytic therapy has any benefit in preventing PPES. This article reviewed the research progress of early risk stratification and prognosis assessment, early major bleeding risk assessment, thrombolytic drug dose reduction, interventional thrombolysis and the long-term prognosis of PTE thrombolysis in recent years.
