Aim of this study was to identify preprocedural parameters, which may predict the application of a complex IVC filter retrieval technique and estimate the procedural outcome by applying two dedicated score systems.
In this retrospective multicenter analysis, data concerning patient, filter and procedure characteristics were retrieved from January 2018 to March 2020. Patients were evaluated according to the retrieval technique (standard vs. complex) and the procedural outcome (success vs. failure). Significant differences among these groups were evaluated, and two score systems were developed to predict the application of a complex retrieval technique and the procedural outcome.
One hundred and sixteen IVC filters were retrieved in 116 patients. In 98 subjects, the filter was retrieved with a standard procedure (Standard group, 84.5% vs. Complex group, 15.5%), while in 106 patients the procedure was successful (Success group, 91.4% vs. Failure group, 8.6%). Statistically significant differences were noted in terms of embedded filter hook, filter apex tilt, angle between filter axis and IVC, caval wall penetration, dwelling time and procedural time. Two score 0-5 points to predict the need for a complex retrieval technique and the procedural outcome were developed, with a prognostic accuracy of 88.8% and 91.4%, respectively.
Significant differences were appreciable analyzing the sample data comparing both the retrieval technique applied and the procedural outcome. Two predictive scores were developed to assess the need for applying a complex retrieval technique and to estimate the procedural outcome.
本研究旨在确定术前参数，这些参数可以预测复杂的下腔静脉滤器回收技术的应用，并通过应用两种专用评分系统来评估手术结果。
在这项回顾性多中心分析中，从 2018 年 1 月至 2020 年 3 月检索了有关患者、滤器和手术特征的数据。根据回收技术（标准与复杂）和手术结果（成功与失败）对患者进行评估。评估这些组之间的显著差异，并开发了两种评分系统来预测复杂回收技术的应用和手术结果。
在 116 名患者中回收了 116 个下腔静脉滤器。在 98 名患者中，滤器采用标准程序回收（标准组 84.5%，复杂组 15.5%），而在 106 名患者中手术成功（成功组 91.4%，失败组 8.6%）。在嵌入滤器钩、滤器尖端倾斜、滤器轴与下腔静脉之间的角度、腔静脉壁穿透、留置时间和手术时间方面，差异具有统计学意义。开发了两个 0-5 分的评分系统，以预测复杂回收技术的需求和手术结果，预测准确性分别为 88.8%和 91.4%。
比较回收技术的应用和手术结果，可以分析出样本数据的显著差异。开发了两种预测评分来评估应用复杂回收技术的需求，并估计手术结果。
