Different retrieval kits for ultra-long time window OptEase inferior vena cava filter / 中国介入影像与治疗学

ABSTRACT

Objective: To observe the effect of Cook retrieval group set to retrieve super long time window OptEase inferior vena cava (IVC) filter. Methods: Clinical data of 289 patients who underwent retrieval OptEase recoverable IVC filter were retrospectively analyzed. IVC filters were retrieved in normal time window (the time of filter placement ≤14 days) in 242 cases, including 127 using OptEase retrieval sets (group A) and 115 using Cook retrieval sets (group B).Meanwhile, IVC filters of 47 cases were retrieved in the ultra-long time window (the time of filter placement >28 days), including 22 using OptEase retrieval sets (group C) and 25 using Cook retrieval sets (group D). The filter retrieval success rates, retrieval time and complication rates were compared between group A and B, group C and D. Results: IVC filters were successfully retrieved in group A and B. There was no significant difference of retrieval time nor complication rate between group A and B (both P>0.05). The success rate of filter retrieval in group D was higher than that in group C (P<0.05), while the retrieval time and complication rate of group D were both lower than those in group C (both P<0.05).No serious complication occurred. Conclusion: The retrieval effect of Cook filter retrieval set is good for ultra long-term time window OptEase venous filter.
