Feasibility study on ultrasound-guided vena cava filter implantation and its clinical application

ObjectiveTo explore the feasibility, safety and clinical value of vena cava filter (VCF) implantation under the guidance of color ultrasound.

MethodsThe data of 203 patients undergoing vena cava filter (VCF) implantation were collected.Among them, twenty-one patients were placed VCF under the guidance of color ultrasound (ultrasound-guided group), and 182 patients were placed VCF under the guidance of DSA (DSA-guided group).The hospitalization time, hospitalization cost, operation time, filter tilt rate, operation success rate, and VCF-related complications during follow-up were compared between the two groups.

ResultsThere was no significant difference in the success rate and filter tilt rate between the two groups (P>0.05).The hospitalization time, hospitalization cost and operation time in ultrasound-guided group were lower than those in DSA-guided group (P < 0.05 to P < 0.01).There was no VCF-related complications during the follow-up of 3 to 6 months.

ConclusionsBoth ultrasound-guided and DSA-guided VCF implantation have good safety and feasibility.Color Doppler ultrasound guidance is more suitable for patients with contrast medium allergy, renal insufficiency and difficulty in moving, which is worthy of clinical promotion.
