Abstract:
Objective To explore the techniques and strategies for the retrieval of the retractable inferior vena cava filter (IVCF).Methods Celect IVCF retrieval was not removed successfully with Gtünther Celect recovery device in 9 cases and exchange-wire-loop removal of inferior vena cava filter method were applicated.Results The longest implanted time of 9 patients was 142 days,the shortest implanted time was 37 days,and the average time was (88.67±33.85)days.Eight fil ters were successfully removed and one failed due to severe bending of inferior vena cava.Filter retrieval rate was 88.89％ (8/9).The average retrieval time was (69.89± 12.12)min (57-162 min).No perforation of the wall and contrast agent were found in all patients after the inferior vena cava angiography.Conclusion For the retrieval of the hook heavily atta ched to the IVCF,the retrieval technique of using the exchange wire into the loop method can effectively improve the retrieval rate and has a certain clinical value.
