Temporary inferior vena cava filter combined with catheter contact thrombolysis in the treatment of acute pulmonary embolism secondary to pelvic vein thrombosis

Abstract

Objective To investigate the treatment methods and efficacy of acute pulmonary embolism. Methods The diagnosis and treatment information of 8 patients with APE secondary to pelvic vein thrombosis admitted by the Changsha First Hospital from 2020 to 2021 were recorded and analyzed. All patients treated with temporary inferior vena cava filter combined with catheter contact thrombolysis. The prognosis was analyzed after the 3-month follow-up. Results After treatment, Arterial partial pressure of oxygen increased from （52.83±4.18） mmHg to （92.34±6.12） mmHg （t=33.221, P＜0.01）, and blood oxygen saturation increased from (80.83±5.34)% to (96.12±4.11)% （t=13.853, P＜0.01）. The shock index and Miller's score significantly decreased. All patients recovered and were discharged, with an average hospital stay of 17.5 days. The recovery rate of the temporary inferior vena cava filter was 100%, with an average recovery time of 3.38 weeks. After 3 months, pulmonary artery CTA showed a 100% patency rate of the pulmonary artery tunk. Conclusion The combination of temporary inferior vena cava filter and catheter contact thrombolysis is a safe and effective treatment for acute pulmonary embolism secondary to pelvic vein thrombosis.
