There is wide variation in the practice of IVC filter placement and retrievals. We conducted a retrospective study to identify the trends in placement and retrievals of IVC filters in a tertiary referral centre in India.
The data of patients obtained from our hospital records, in whom IVC filter was placed between 2010 and 2018, were analysed for demographics, indications for placement of IVC filter, underlying comorbidities, characteristics of the filters as well as the retrieval rates.
IVC filters were placed in 50 patients, and data was retrieved for 31 patients (mean - 51.24 years, 67.74% males). According to ACCP/AHA guidelines, 24 (77.42%) had an absolute indication for IVC filter. All 31 IVC filters were temporary, 23 (74.19%) of which were placed via femoral access. 29(93.55%) patients had infrarenal IVC filter placement. The average tilt at deployment was 3.71°, whereas it was 5.3° at retrieval. There were no periprocedural complications or filter migrations during placement or retrieval. Retrieval was attempted in 11 (35.48%) patients and was successful in 10. The mean indwelling time in this group was 158.55 days (range 55-366 days).
Our study reveals low IVC filter implantation rates which are predominantly for absolute rather than relative indications. Though in sync with the worldwide trend, the poor retrieval rates reflect the urgent need for better patient and physician awareness. Periodic follow up is imperative to improve the IVC filter retrieval rate and to prevent complication rates.
静脉滤器的放置和取出操作存在广泛的差异。我们进行了一项回顾性研究，以确定在印度的一家三级转诊中心静脉滤器放置和取出的趋势。
我们分析了 2010 年至 2018 年间在我院记录中放置静脉滤器的患者数据，内容包括人口统计学资料、静脉滤器放置的适应证、基础合并症、滤器特征以及取出率。
共 50 例患者放置了静脉滤器，其中 31 例（平均年龄 51.24 岁，67.74%为男性）的数据被检索到。根据 ACCP/AHA 指南，24 例（77.42%）有静脉滤器放置的绝对适应证。所有 31 例静脉滤器均为临时滤器，其中 23 例（74.19%）通过股静脉入路放置。29 例（93.55%）患者行肾下腔静脉滤器放置。植入时平均倾斜度为 3.71°，取出时为 5.3°。在放置或取出过程中无围手术期并发症或滤器移位。11 例（35.48%）患者尝试取出，10 例成功。该组的平均留置时间为 158.55 天（55-366 天）。
我们的研究显示，静脉滤器植入率较低，主要是因为绝对适应证而非相对适应证。尽管与全球趋势一致，但较差的取出率反映了迫切需要提高患者和医生的认识。定期随访对于提高静脉滤器取出率和预防并发症发生率至关重要。
