  • Title: [Temporary cava filter: effective prophylaxis of pulmonary embolism in venous thrombosis in the region of the pelvic vascular system and the inferior vena cava?].
    Author: Kunisch M, Rauber K, Bachmann G, Rau WS.
    Journal: Rofo; 1995 Dec; 163(6):523-6. PubMed ID: 8547623.
    Abstract:
    PURPOSE: To assess the temporary Günther filter system concerning handling, complication rate and efficacy in respect to prophylaxis of pulmonary embolism. PATIENTS AND METHODS: 45 temporary Günther filters were placed in 44 patients (mean age 46 years) with deep venous thrombosis of the iliac and/or inferior vena cava. RESULTS: The mean time until filter retrieval was 6.1 +/- 4.1 days (maximum 14 days) dependent on the success of either thrombolytic therapy or thrombus consolidation. 27 patients underwent systemic thrombolytic therapy (61%), three patients (7%) received local thrombolysis. 14 patients (32%) were treated with heparin in a therapeutic dosage (PTT > 60 sec). We observed four complications (8.8%): one accidental arterial puncture (carotid artery on attempting an internal jugular vein approach), one infection located at the puncture site and one caval vein thrombosis in a patient with known heparin-associated thrombocytopenia. One patient died of pulmonary embolism despite correct filter positioning. CONCLUSION: Percutaneous placement of inferior vena cava filters is therefore an easy, safe and effective prophylaxis in respect of pulmonary embolism if combined with thrombolytic therapy or therapeutic heparinisation.
