Intrapulmonary rotational power-driven thrombectomy therapy for acute massive pulmonary thromboembolism / 中国综合临床

ABSTRACT

Objective To investigate the effect and safety of rotational power-driven thrombectomy therapy through intrapulmonary for acute massive pulmonary thromboembolism.Methods Sixteen patients of acute massive pulmonary thromboembolism diagnosed by CT and pulmonary angiography were treated with Straub Rotarex system.The successful rate,release of clinical manifestations and the blood hemodynamic changes were observed and analyzed.Results The clinical manifestations were improved remarkably in all the 16 patients,arterial partial pressure of oxygen,saturation of arterial blood oxygen,shock index,Miller score and mPAP were (56.7± 13.4) mm Hg,84.1 ± 10.4)％,(1.27 ±-0.39),(22.7±11.4) and (36.3 ±9.4) mm Hg respectively before treatment,and (92.2 ± 8.6) mm Hg,(96.6 ± 12.7) ％,(0.57 ± 0.42),(12.1 ± 7.8)points and (21.9 ± 7.3) mm Hg respectively after treatment,which were all improved significantly (t =-2.794,2.601,-2.592,-2.638,-2.617,P ＜ 0.01).Conclusion Rotational power-driven thrombectomy therapy through intrapulmonary is an effective and safe technique for the treatment of acute massive pulmonary embolism.
