PURPOSE: To evaluate of the medium-term integrity, efficacy, and complication rate associated with the Gunther Tulip vena cava filter.
METHODS: A retrospective study was performed of 369 consecutive patients who had infrarenal Gunther Tulip inferior vena cava filters placed over a 5-year period. The mean patient age was 61.8 years, and 59% were men. Venous thromboembolic disease and a contraindication to or complication of anticoagulation were the indications for filter placement in 86% of patients; 14% were placed for prophylaxis in patients with a mean of 2.3 risk factors. Follow-up was obtained by review of medical and radiologic records.
RESULTS: Mean clinical follow-up was 780 days. New or recurrent pulmonary embolus occurred in 12 patients (3.3%). New or recurrent deep-vein thrombosis occurred in 53 patients (14.4%). There were no symptomatic fractures, migrations, or caval perforations. Imaging follow-up in 287 patients (77.8%) at a mean of 731 days revealed a single (0.3%) asymptomatic fracture, migration greater than 2 cm in 36 patients (12.5%), and no case of embolization. Of 122 patients with CT scans, asymptomatic perforations were identified in 53 patients (43.4%) at a mean 757 days.
CONCLUSION: The Gunther Tulip filter was safe and effective at 2-year follow-up. Complication rates were similar to those reported for permanent inferior vena cava filters.
