Abstract

Purpose: To compare the tilt of the classical ALN® inferior vena cava filter (IVCF) with that of the new Optional Anti-Tilting Filter (OATF) in a single-center retrospective study.

Materials and methods: This retrospective study analyzed fluoroscopic images from 539 patients who received an IVCF between April 2012 and March 2023. The primary outcome was the frontal view tilt angle of the IVCF within the IVC at insertion between the ALN classical filter (ACF) and the new OATF. Secondary outcomes included a comparison of tilt between these two filters at retrieval, as well as a correlation between tilt and fluoroscopy time. Imaging and clinical data were collected from hospital databases, and statistical analysis was conducted using regression models.

Results: At placement, in the frontal plane, median tilt was significantly lower in the OATF group (5° [2°-10°]) than in the ACF group (10° [6°-15°]) (p<0.01). At retrieval, median frontal plane tilt was significantly lower in the OATF group (3.5° [1°-10°]) than in the ACF group (11° [5°-16.5°]) (p<0.01). Median lateral plane tilt at retrieval was also significantly lower in the OATF group (3° [1°-6.5°]) than in the ACF group (8° [4°-13°]) (p < 0.001). At retrieval, front plane tilt was correlated with fluoroscopy time (Spearman correlation coefficient: 0.165; n=184) (p=0.033).

Discussion: These findings indicate that the OATF is associated with reduced tilt compared to the classical model.

评估下腔静脉过滤器的倾斜和检索挑战：ALN过滤器原始模型和反倾斜模型的比较。

目的：在一项单中心回顾性研究中，比较经典ALN®下腔静脉滤过器（IVCF）与新型可选抗倾斜滤过器（OATF）的倾斜度。材料和方法：本回顾性研究分析了2012年4月至2023年3月期间接受IVCF的539例患者的透视图像。主要结果是在ALN经典滤波器（ACF）和新OATF之间插入时IVCF在IVC内的正面视图倾斜角。次要结果包括两种滤镜在检索时的倾斜度比较，以及倾斜度与透视时间的相关性。从医院数据库中收集影像学和临床资料，采用回归模型进行统计分析。结果：在放置时，在额平面上，OATF组的中位倾斜度（5°[2°-10°]）显著低于ACF组（10°[6°-15°]）。
