Eighty consecutive patients with an average age of 66.5 +/- 16 years were reviewed 3 and 9 months after implantation of two new percutaneous vena caval filters (Filcard, Cardial) in order to evaluate their efficacy and tolerance. The indications were: a contra-indication to anticoagulants in 19 cases, recurrent pulmonary embolism under anticoagulant therapy in 22 patients, chronic cor pulmonale in 4 patients; finally, in 35 cases, the filter was implanted prophylactically for a "floating" or extensive ilio-caval thrombosis under anticoagulant therapy or in high risk patients: severe cardio-pulmonary failure, malignant disease, massive pulmonary embolism with a contra-indication to fibrinolytic therapy. All implantations were performed by the jugular approach with no local or general complications apart from one pericaval haematoma with a favourable outcome. Cavography and opacification of the renal veins was carried out systematically during implantation. All patients underwent clinical examination, antero-posterior and lateral X rays of the filter, pulmonary scintigraphy, antero-posterior and lateral cavography, a CT scan of the filter, Doppler ultrasonography and rheoplethysmography of the legs 3 months after implantation. At 9 months, clinical examination, abdominal X rays and rheoplethysmography were repeated. There was 100% follow-up at 3 and 9 months. The complications observed at 3 and 9 months were: 5 cases of malposition (6%), 3 recurrent pulmonary emboli (4%), 9 recurrent venous thromboses (13%), 4 vena caval thromboses (5.7%), 7 thrombi caught in the filter (10%), 27 perforations of the vena cava (38%), 3 over 30 degrees tilts of the filter (4%) and 22 migrations (31%).(ABSTRACT TRUNCATED AT 250 WORDS)
