Abstract:
Background and Aims:The Octoparms filter is a newly introduced domestically manufactured umbrella-shaped retrievable inferior vena cava (IVC) filter. A multicenter,parallel-controlled trial demonstrated its non-inferiority to the Celect filter. This study was performed to compare the clinical outcomes of the placement and retrieval of the Octoparms filter with those of the Denali filter to assess its safety and efficacy further.Methods:From May 2021 to May 2024,289 Denali filters (Denali group) and 78 Octoparms filters (Octoparms group) were placed and attempted to be retrieved at Beijing Shijitan Hospital,affiliated with Capital Medical University. After propensity score matching (PSM) of baseline characteristics,the incidence of filter tilt,wall apposition,vein wall penetration,retrieval success rates,and other relevant variables were compared between the two groups.Results:After PSM,77 patients were included in each group. Following matching,except for the significantly lower placement cost in the Octoparms group (P<0.05),all baseline characteristics (e.g.,gender,age,surgical indications,filter insertion route,IVC diameter,and angle) showed no statistically significant differences between the two groups (all P>0.05). The average indwelling time of the filter was longer in the Denali group compared to the Octoparms group (58 d vs. 47 d,P=0.004). There was no significant difference in the average filter tilt angle between the two groups (4.4° vs. 4.8°,P=0.71). While wall apposition or significant tilt was more frequent in the Octoparms group,the difference was not statistically significant (P>0.05). Both groups achieved a 100.0％ technical success rate for filter retrieval,with no complications such as filter fracture or vascular rupture during retrieval. Other retrieval-related variables (surgical approach,retrieval duration,retrieval techniques,and costs) also showed no significant differences between the two groups (all P>0.05).Conclusion:As a newly launched domestic filter,the Octoparms filter demonstrates comparable stability and retrieval rate to the Denali filter,and it is a safe and reliable choice.
