ABSTRACT
The use of retrievable inferior vena cava (IVC) filters has markedly increased in the recent years. However, the failure rate for the retrieval of the IVC filters using the endovascular method is reported to be up to 19%. Open surgical removal of the IVC filters is technically challenging and may require longitudinal cavotomy, clamping, and repair of the IVC. Here, we present a case of successful open surgical removal of the IVC filter using minimal cavotomy. This technique is an effective method after a failed endovascular removal attempt.

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.
ABSTRACT
El tromboembolismo venoso es una patología que ocurre aproximadamente en 1 de cada 1 000 personas en el mundo, de las cuales más de la mitad corresponde a casos de trombosis venosa profunda. La principal complicación aguda de la trombosis venosa profunda es el embolismo pulmonar, que resulta fatal en 20%-30% de los casos. La anticoagulación es la estrategia más eficaz para la prevención de esta complicación, sin embargo, está contraindicada en situaciones frecuentes. Los filtros de vena cava inferior constituyen una alternativa no farmacológica para la prevención del embolismo pulmonar en aquellos pacientes que presentan trombosis venosa profunda. Este artículo hace revisión de los aspectos históricos de estos dispositivos, con especial interés en los denominados filtros recuperables, en cuanto a sus indicaciones, técnica de colocación-retiro, eficacia y seguridad
Venous thromboembolism is a disease which occurs in 1 out of 1000 people around the world, accounting for about a half of cases of deep venous thrombosis. Deep venous thrombosis major complication is pulmonary embolism, fatal in 20%-30% of cases. Anticoagulation is the most effective strategy to prevent pulmonary embolism, however, this is contraindicated in frequent clinical situations. Inferior vena cava filters are a non-pharmacological alternative in these cases. This article reviews historical aspects of these devices, with particular interest in those denominated retrievable filters, describing indications, implantation-retrieval technique, efficacy and safety
