Comparative Analysis of the Effect of Acostream Catheter for Pulmonary Artery Thrombus Aspiration and Pulmonary Artery Catheterization and Thrombolysis in Patients with Pulmonary Embolism
Objective:To compare and analyze the application effects of Acostream catheter-directed pulmonary artery thrombus aspiration(ACTA)and pulmonary artery catheter thrombolysis(PACT)in patients with pulmonary embolism(PE).Methods:90 interme-diate and high-risk PE patients admitted to 2022.1-2024.3 were selected and divided into the ACTA group and the PACT group,with 45 patients each.The PACT group was given urokinase pulmonary artery catheterization for thrombolysis,and the ACTA group was given a Acostream catheter for pulmonary artery thrombus aspiration.Compare the two groups of relevant indicators.Results:(1)The total re-sponse rate was higher in the ACTA group than in the PACT group(P=0.025).(2)After treatment,the RV size,TR,PASP,and PADP all decreased in the ACTA group compared with the PACT group(P＜0.05).(3)After treatment,PaO2 increased in the ACTA and PACT groups compared with PaCO2 decreased before treatment,and the improvement in the ACTA group was greater than that in the PACT group(P＜0.05).Plasma BNP and cTnⅠ and D-dimer levels were lower after both treatment than before treatment,and the decrease was more pronounced in the ACTA group(P＜0.05).(4)The complication rate was lower in the ACTA group than that in the PACT group(P＜0.05).Conclusion:ACTA in patients with acute PE can quickly remove embolic vascular thrombosis,restore pulmonary artery blood flow,improve blood gas status,with excellent efficacy,low risk of complications and high safety.
