Abstract: Objective To explore the technique and clinical application of Fustar combined with disposable biopsy forceps in the recovery of inferior vena cava filter. Methods A retrospective analysis of 117 cases of the inferior vena cava filter recovered from December 2017 to December 2020 in Wangjing Hospital of the Chinese Academy of Chinese Medical Sciences.The Fustar combined with disposable biopsy forceps were used during the operation.The filter was successfully recovered and performed after the operation.Follow-up observation. Results In this study,117 cases of vena cava filters,including 103 cases of Aegisy filter,9 cases of Optease filter,and 5 cases of Günther Tulip filter,were successfully recovered using the Fustar combined with disposable biopsy forceps,and the recovery success rate was 100%.The operation time of grasping the filter under fluoroscopy It was 45 seconds to 12 minutes and 57 seconds,with an average of 2 minutes and 38 seconds.The angiography showed that the inferior vena cava blood flowed smoothly,and there was no extravasation of contrast agent.Observation and removal of the filter was normal,without deformation or damage.The patients were followed up for 1 to 36 months,with an average of 6 months,and there were no complications such as inferior vena cava stenosis or secondary thrombosis. Conclusion The Fustar combined with disposable biopsy forceps in the recovery of the inferior vena cava filter has the characteristics of simple operation,small trauma,accurate positioning,high recovery rate,and short operation time.It can be promoted as the preferred solution for recovery of vena cava filter.
