Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Acute pulmonary embolism (PE) accounts for 5-10% of in-hospital deaths. Systemic anticoagulation (AC) is the standard of care and thrombolysis is recommended for those at a higher mortality risk. Catheter-directed therapies, mainly standard infusion catheter thrombolysis (CDT) and ultrasound-accelerated thrombolysis (USAT), have been introduced as new more effective and safer treatment modalities. USAT is a modification of standard catheter lysis utilizing a system of local ultrasound to dissociate the fibrin matrix of the thrombus with simultaneous acoustic streaming of the thrombolytic agent, allowing more efficient thrombolysis. However, there is limited comparative effectiveness data against standard multi-side hole catheter infusion. More rapid clearance of pulmonary thrombus by USAT compared to standard CDT may prove to be clinically beneficial and cost effective. Alternatively, if thrombus clearance is similar, the cost of USAT may exceed the cost of CDT (equipment and disposables), without realization any advantage.
