    Abstract:
    Anticoagulant and thrombolytic therapies are a mainstay in the management of acute pulmonary embolism (PE), especially when hemodynamic compromise is present. However, systemic drugs cannot achieve timely and effective treatment of acute PE in all patients. In such a setting, mechanical removal of thrombus from the pulmonary circulation holds the promise of significant clinical benefits, although it remains untested. We report early and long-term outcome of patients with massive or submassive acute PE treated with rheolytic thrombectomy by means of the 6Fr Xpeedior AngioJet device at our institution. Three main groups were defined pre hoc: subjects with severe (i.e., shock), moderate, or mild hemodynamic compromise. Technical and procedural successes, obstruction, perfusion and Miller indexes, and clinical events were appraised. In total 25 patients were treated with thrombectomy (8 in severe, 12 in moderate, and 5 in mild hemodynamic compromise). Technical and procedural successes were obtained in all patients, as confirmed by the significant improvement in obstruction, perfusion and Miller indexes overall, and in each subgroup (all p values <0.001). Improvement in obstruction, perfusion, and Miller indexes at the end of the procedure could also be confirmed in patients (n = 8) treated with local fibrinolysis and in the absence of concomitant thrombolysis (n = 17, p <0.05). Four patients died in hospital, all other patients but 1 were safely discharged after an appropriate hospital stay, and all were alive at long-term follow-up (median 61 months). In conclusion, this study supports at early and long-term follow-up the effectiveness and safety of rheolytic thrombectomy for PE.
