Abstract:
Objective:To investigate the safety and efficacy of AngioJet rheolytic thrombectomy (ART) treatment in patients with acute pulmonary embolism (APE).Methods:The clinical data of 21 consecutive APE patients with failed fibrinolytic therapy or fibrinolytic therapy contraindications were reviewed retrospectively, from January 2017 to October 2018 in Henan Provincial people's Hospital. Patients were classified into massive pulmonary embolism (MPE, 10 cases) and sub-massive pulmonary embolism (sMPE, 11 cases) according to the clinical presentation and CT angiography (CTA) results. All the patients were treated with emergency ART. The technical success rate and procedural success rate were calculated based on the angiography results and the occurrence of serious adverse events. The pre- and postoperative parameters including shock index (SI), Miller index (MI), mean pulmonary artery pressure (MPAP) and partial pressure of arterial oxygen (PaO 2) were compared using independent sample t test or Wilcoxon signed ranks test. Results:The technical success rate was 100% (21/21), and the procedural success rate was 71.4%(15/21) with 4 patients presenting severe arrhythmia, 1 patient with intraoperative severe dyspnea and 1 patient with intracranial hemorrhage. Both MPE and sMPE patients showed improvement of clinical symptoms after operation. It showed that the postoperative SI, MI and MPAP values decreased and PaO 2 increased compared with the preoperative values, with significant differences found (all P<0.05). All patients were discharged from hospital, except 1 patients left hospital due to serious illness. The mean follow-up period was (5.3±1.2) months, and 2 MPE patients expired due to cancer and acute myocardial infarction. All survivors didn't show recurrent APE symptoms and follow-up CTA showed no signs of embolism in pulmonary artery. Conclusion:ART can be used safely and effectively in APE patients, and can be prosposed as a new strategy in treatment of APE.
