Objective To discuss and evaluate the value of insertion of inferior vena cava filter in treating lower extremity deep venous thrombosis (DVT). Methods Inferior vena cava filters were placed in 46 patients with lower extremity DVT prior treatment, 20 in which were treated by therapy with anticoagulation and thrombolysis, and therapy with pressure gradient, and the other 26 patients by operation and thrombolysis therapy, and therapy with pressure gradient. Whether patients occurred pulmonary embolism was observed and the form and site of filters were monitored by periodic fluoroscopy. Results Inferior vena cava filters were placed successfully in all patients, 38 cases were implanted permanence inferior vena cava filter, 8 cases were implanted temporary inferior vena cava filter. Symptoms and signs of DVT disappeared or remitted in 44/46 patients after treatment. None of pulmonary embolism was occurred. Follow up 2-24 months (average 13 months) for 36 cases with permanence inferior vena cava filter, there was no complication of the filter and pulmonary embolism occurred. Conclusions The method of inserting inferior vena cava filter is simple and safe, which can prevent pulmonary embolism effectually to offer sufficient safeguard for the treatment of DVT.
