Massive pulmonary embolism (PE) is a life-threatening condition. This study analyzes endovascular treatments, including ultrasound-accelerated thrombolysis, for acute PE, offering insights into catheter-based interventions.
Area of Science:
- Cardiology
- Interventional Radiology
- Pulmonary Medicine
Background:
- Massive pulmonary embolism (PE) presents with hemodynamic instability and acute right ventricular (RV) failure, posing a high mortality risk.
- Submassive PE, characterized by RV failure or troponin elevation, can lead to severe outcomes without prompt intervention.
- Current management emphasizes rapid risk stratification and aggressive treatment for massive PE.
Purpose of the Study:
- To analyze various endovascular treatment strategies for massive and submassive pulmonary embolism (PE).
- To discuss institutional experience with ultrasound-accelerated and catheter-directed thrombolytic therapy for acute massive PE over a decade.
- To review clinical evidence supporting catheter-based interventions in PE management.
Main Methods:
- Analysis of diverse endovascular treatment strategies for PE.
- Review of a 10-year institutional experience with ultrasound-accelerated thrombolytic therapy (UATT) and catheter-directed thrombolysis (CDT) in acute massive PE.
- Examination of clinical evidence for catheter-based interventions in massive and submassive PE.
Main Results:
- Endovascular technologies offer various catheter-based thrombectomy and thrombolytic devices for PE treatment.
- Institutional data on UATT and CDT for acute massive PE over a 10-year period are presented.
- Clinical evidence regarding the efficacy of catheter-based interventions in massive and submassive PE is analyzed.
Conclusions:
- Endovascular therapies are increasingly utilized for managing massive and submassive PE.
- Catheter-based interventions, including UATT and CDT, represent viable therapeutic options for acute PE.
- Further analysis of clinical evidence supports the role of endovascular approaches in PE treatment paradigms.

These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
