Study of a Novel Thrombectomy Device to Treat Acute Iliofemoral Deep Venous Thrombosis

15. januar 2017 opdateret af: Qianxin Huang, Xuzhou Medical University

Study on the Application of a Novel Aspiration Thrombectomy Device Combined With Catheter-directed Thrombolysis for the Treatment of Acute Iliofemoral Deep Venous Thrombosis

The purpose of this study is to determine whether the novel aspiration thrombectomy device combined with catheter-directed thrombolysis is effective in the treatment of acute iliofemoral deep venous thrombosis (IF-DVT).

Studieoversigt

Detaljeret beskrivelse

Catheter-directed thrombolysis will be performed in eligible patients with acute IF-DVT. A combined mechanical thrombectomy will be used to clear the iliac thrombi in experimental group. The immediate, mid- and long-term outcomes will be recorded. Quantitative data wiil be expressed as mean ± SD, and will be compared with independent-sample t-test or paired-sample t-test. Count data will be expressed as a ratio (or percentage), and the chi-square test or the fisher's exact test will be used for comparisons. A difference with P < 0.05 will be considered statistically significant. All statistical analyses will be performed using IBM SPSS, version 22.0 (SPSS Inc., Chicago, IL, USA).

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Combined thrombectomy device
A manual spiral thrombus broken suction device will be used for thrombectomy before catheter-directed thrombolysis. Ten million U of urokinase once every 4-6 hours will be used during catheter-directed thrombolysis therapy. Anticoagulation therapy will be administered via subcutaneous injection of low-molecular-weight heparin calcium (LMWH-Ca 5,000 U/12 h) at discharge

catheter-directed thrombolysis will be used in both arms
anticoagulation therapy will be administered via subcutaneous injection of low-molecular-weight heparin calcium (LMWH-Ca 5,000 U/12 h) in both arms at discharge
Andre navne:
  • Low-Molecular-Weight Heparin Calcium for Injection
A total of 100,000 units urokinase once every 4-6 hours will be used during catheter-directed thrombolysis therapy
Andre navne:
  • Urokinase for Injection
Andet: Catheter-directed thrombolysis
Participants will undergo catheter-directed thrombolysis alone. A total of 100,000 units urokinase will be pulse-spray injected through the catheter once every 4-6 h.
