Abstract:
Objective To evaluate the effectiveness and safety of interventional embolectomy in the treatment of acute massive pulmonary embolism. Methods Interventional managements, including fragmentation, aspiration and dissolving of the embolus, were performed in 12 patients with CTPA-or pulmonary angiography-proved acute massive pulmonary embolism. Clinical manifestations, blood gas tension, hemodynamic changes, the recanalization of the pulmonary artery as well as the occurrence of complications were observed. Results Eleven patients survived and nine patients showed significant clinical improvement. PaO2 was increased from (54.92 ? 6.17)mmHg before the procedure to (90.91 ? 1.62)mmHg after the procedure (P = 0.001), and SaO2 was also increased from (85.17 ? 8.39)mmHg before the procedure to (95.75 ? 1.96)mmHg after the procedure (P = 0.001). Miller score (21.75 ? 4.35 vs 13.83 ? 5.69, P = 0.001) and mPAP (25.59 ? 7.68 mmHg vs 30.04 ? 7.93 mmHg, P = 0.001)decreased significantly. One patient died of pulmonary embolism and one died of intracerebral bleeding three days after the procedure. Conclusion Interventional embolectomy is an effective and safe technique for the treatment of acute massive pulmonary embolism.
