Abstract
Background: Although thrombolysis is a standard therapy in cases of pulmonary embolism (PE), fatal outcome is often observed. We designed and investigated the efficacy of a novel percutaneous catheter therapy, rotational bidirectional thrombectomy (ROBOT), for PE. Methods and Results: Eighteen patients with acute massive PE (Miller score > 20) were included in this study. We separated them into two groups [group A (n = 10), thrombolysis; group B (n = 8): thrombolysis and ROBOT or ROBOT alone]. There was no difference in the hemodynamic indices between the groups at diagnosis. ROBOT was designed to fragment emboli by rotating a regular pigtail catheter. Three deaths occurred in group A because of hemodynamic impairment, but there was no death in group B. One day after treatment, systolic pulmonary artery pressure had decreased from 53 ± 8 to 30 ± 8 mm Hg (P <0.05) in group B and from 54 ± 5 to 42 ± 19 mm Hg (NS) in group A. The hospitalization period in group B was shorter than that in group A (17 ± 6 vs. 27 ± 10 days, P <0.05). Conclusion: ROBOT therapy results in a significant, rapid improvement in the hemodynamic situation and in a better outcome than conventional therapy in patients with acute massive pulmonary embolism.
