About this trial
International guidelines recommend immediate reperfusion with systemic thrombolysis (ST) as first-line treatment in high-risk pulmonary embolism (PE). The therapy improves hemodynamics and overall survival but is also associated with a significant risk of severe bleeding. Catheter-directed intervention (CDI) is recommended as an alternative reperfusion therapy in high-risk PE when ST is contraindicated or has failed, as well as in patients who deteriorate or fail to improve during anticoagulation (AC) treatment. Despite lack of high-quality evidence and randomized studies between CDI and standard care, the use of CDI is spreading rapidly in high-risk PE and in less severe PE not fulfilling current treatment criteria.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
All adult patients (≥18 years), including pregnant women, with verified (CTPA, angiography or scintigraphy) acute pulmonary embolism who are planned for, or have received, treatment with catheter directed intervention or systemic thrombolysis
Informed consent (for patients who do not survive before informed consent can be obtained, a waiver of consent applies)
Disqualifiers
Ongoing enrolment in interventional catheter directed intervention trial
Surgical embolectomy as primary reperfusion treatment
Trial population
Pulmonary embolism patients treated with catheter directed intervention or systemtic thrombolysis in hospitals in Sweden and Denmark where the former treatment modality is established.
