Advanced Management of Patients Undergoing Transcatheter Treatment for Pulmonary Embolism: Evidence-Based Strategies for Optimized Patient Care

Abstract

Pulmonary embolism (PE) is a life-threatening medical condition caused by the thrombotic occlusion of one or more branches of the lung vasculature, which represents the third most common cause of cardiovascular mortality after myocardial infarction and stroke. PE treatment requires a tailored approach based on accurate risk stratification and personalized treatment decision-making. Anticoagulation is the cornerstone of PE management, yet patients at higher clinical risk may require more rapid reperfusion therapies. In recent years, transcatheter treatment has emerged as a valuable option for patients with intermediate–high or high-risk PE who have contraindications to systemic thrombolysis. Recent advancements in catheter-directed therapies, such as catheterdirected thrombolysis (CDT) and catheter-directed mechanical thrombectomy (CDMT), provide minimally invasive options for swift symptom relief and hemodynamic stabilization. This review aims to provide a practical approach for optimal patient selection and management for PE percutaneous therapies, supported by a thorough evaluation of the current evidence base supporting these procedures. A focus on post-procedural management, the prevention of recurrence, and monitoring for long-term complications such as chronic pulmonary hypertension and post-PE syndrome is also specifically tackled.
