Catheter-interventional Treatment of Pulmonary Embolism

Recent evidence supports the use of catheter-interventional techniques for the treatment of intermediate-high-risk pulmonary embolism. While there is evidence supporting the use of catheter-thrombectomy and alternatively local fibrinolysis, less is known on the combination of both approaches. The investigators aim to assess the effects of a combined interventional local fibrinolysis and catheter-thrombectomy and to compare them with conventional treatment in a cohort of patients with intermediate-high-risk pulmonary embolism.
