Management of failed inferior vena cava filter retrieval for complex cases: A case series.

The aim of this report is to describe our experience in managing cases of difficult inferior vena cava (IVC) filter retrieval with emphasis on different advanced retrieval techniques. We report three cases of difficult IVC filter retrieval at our institution. We included three patients age ranging from 42 to 72 years. Two of the cases were presenting with the lower limb deep vein thrombosis and one of the cases had pulmonary embolism and they all had Retrievable Celect Platinum IVC filter (Cook Medical, Bloomington, Ind.) inserted preoperatively. One case was managed conservatively after failing IVC filter retrieval using standard retrieval set, meaning the filter was left in place, one was successfully removed with advanced endovascular retrieval techniques, and one failing advanced endovascular retrieval and finally had it removed with open surgery. We reviewed the risk factors contributing to difficult IVC filter retrieval and discussed the different options for managing these cases including conservative management, endovascular treatment, and open surgery for retrievable type of IVC filter which can be placed permanently. Knowledge of these options will help us better understand conditions, leading to difficult IVC retrieval on insertion, hopefully to minimize the occurrence of these cases, and to better manage cases with difficult IVC filter retrieval to decide the best option for each patient after careful consideration and multidisciplinary discussion with surgeons and patients.
