Thrombosis secondary to the inferior vena cava filtration / 中国微创外科杂志

ABSTRACT

Objective To study the causes, prevention and treatment of secondary thrombosis after vena cava filter placement. Methods We summarized the clinical experience regarding 7 cases of secondary thrombosis of the inferior vena cava from December 2001 to June 2004 in this hospital. Results Two patients underwent thrombectomy, 1 patient received interventional thrombolytic therapy, and the rest of 4 patients received conservative treatment. All the treatment had obtained good results. No pulmonary embolism took place in the study. Conclusions Thrombosis secondary to filtration can be completely prevented by adhering strictly to the indications of filter placement and conducting supplementary anticoagulation therapy. Interventional therapy is the first choice for the treatment of secondary thrombosis after filter placement.
