Use of temporary vena cava filters after catheter-directed fragmentation and thrombolysis in patients with acute pulmonary thromboembolism.

Acute pulmonary thromboembolism is a life-threatening disease and in almost all cases originates from deep venous thrombosis in the proximal deep venous system of the legs. In order to prevent further episodes of thromboembolism in 2 patients with acute pulmonary thromboembolism, we inserted an Antheor temporary vena cava filter after catheter-directed fragmentation and thrombolysis. No complications occurred during the insertion of the filters and our results suggest that this filter device may be clinically safe and effective for temporary protection against pulmonary thromboembolism.
