[Treatment with percutaneous transluminal angioplasty of the popliteal and crural arteries].

Background: The role and benefit of percutaneous transluminal angioplasty (PTA) for treatment of arteriosclerotic lesions in the crural arteries has been controversial. The purpose of this study was to review our experience.

Material And Methods: 88 patients were treated with PTA for stenoses and/or occlusions of the popliteal or crural arteries.

Placement of a spring filter during interventional treatment of deep venous thrombosis to reduce the risk of pulmonary embolism.

Purpose: To assess the efficacy of the Spring filter during interventional treatment of deep venous thrombosis in vivo.

Material And Methods: A model of inferior vena cava thrombosis was used. Part I: The thrombus was treated by the pulse-spray technique (PT) (urokinase 250,000 IU; n=7) or a rotatory basket catheter, Thrombolizer (MT) (activated with compressed air at 7 atm; n=5).

In vivo evaluation of the adjustable temporary venous spring filter and the RF02 temporary filter: comparative study.

Rationale And Objectives: The authors performed this study to compare the in vivo efficacies of the temporary venous spring filter and the RF02 filter in an animal model.

Materials And Methods: Either the spring filter or the RF02 filter was placed in the inferior vena cava of 10 pigs each, and two clots (5 x 20 mm) were funneled into the filters at 1-hour intervals. The second clots were funneled without removing the first clots captured by the filters.

In vitro function of an adjustable temporary venous spring filter: comparison with the temporary RF02 filter and the permanent Greenfield vena cava filter.

Rationale And Objectives: The authors compared in vitro function of a temporary venous spring filter with that of a temporary RF02 filter and a permanent Greenfield filter.

Materials And Methods: All three types of filters were placed in thin polyethylene tubes (diameters, 10.0-18.
