Catheter-directed, ultrasound-assisted thrombolysis is a safe and effective treatment for pulmonary embolism, even in high-risk patients

CDUA thrombolysis for acute PE effectively reduced mean PAPs. Given the low incidence of major bleeding complications, even in those deemed to be clinically at high risk for bleeding, we additionally conclude that this procedure can be performed safely. Although larger studies with longer follow-up are necessary, CDUA pulmonary thrombolysis for the management of acute submassive PE appears to be effective in decreasing right-sided heart strain and can be performed with an acceptable risk profile.
