The primary purpose of this study is to compare the Celect and Denali filters in terms of complicated filter retrieval and indwelling complications after a 2-month indwelling time.
With anticoagulation being the standard treatment for deep venous thrombosis and pulmonary embolism, inferior vena cava filter placement plays an important role in patients who are amenable to anticoagulant therapy. Currently, many different types of retrievable filters are being used in clinical practice and the choice of the filters depends on operators' preference and institutional availability. Each filter has different designs to maximize retrievability and minimize indwelling complications. Up until now, the prior studies on the filter retrievability and indwelling complications have been retrospective in nature and had relatively long dwell times. Comparative data regarding the retrievability of the inferior vena cava filters may help to choose filter selection. Therefore, the aim of this trial is to compare two commonly used inferior vena cava filters (Denali and Celet filters)

RECRUITINGIncidence of complicated filter retrieval
Incidence of retrieval cases that require the use of standard retrieval kit (sheath and snare)
Time frame: 2 months after filter placement
Incidence of penetration
