超声引导下腔静脉滤器置入及临床应用的可行性研究

目的探讨彩色超声引导下行下腔静脉滤器（VCF）置入术的可行性、安全性和临床实用价值。方法收集行VCF置入术的203例病人资料，其中21例在彩色超声引导下放置VCF（超声引导组），182例在DSA下放置VCF（DSA引导组），比较2组住院时间、住院费用、手术时间、滤器倾斜率、手术成功率及随访期间VCF相关并发症。结果2组手术成功率、滤器倾斜率差异均无统计学意义（P>0.05）。超声引导组住院时间、住院费用、手术时间均低于DSA引导组（P < 0.05~P < 0.01）。术后随访3~6个月均未出现VCF相关并发症。结论超声引导和DSA引导VCF置入均有很好的安全性及可行性，彩色多普勒超声引导对于造影剂过敏、肾功能不全及搬动困难者更适宜，值得临床推广。

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.
