Ultrasound-Accelerated, Catheter-Directed Thrombolysis for Submassive Pulmonary Embolism: Single-Center Retrospective Review with Intermediate-Term Outcomes.

Purpose: To evaluate ultrasound-accelerated, catheter-directed thrombolysis (CDT) for treatment of acute submassive pulmonary embolism (PE).

Materials And Methods: This single-center, retrospective study included patients who underwent CDT for acute submassive PE (N = 113, 52% men/48% women) from 2013 to 2017. Baseline characteristics included history of deep venous thrombosis (12%), history of PE (6%), and history of cancer (18%).
