PURPOSE: To evaluate the deliverability and protection capabilities of an @entity887 protection filter in angioplasty of peripheral arteries. METHODS: The Angioguard emboli capture guidewire system was applied in 11 @entity1 with femoropopliteal lesions (6 stenoses, 3 occlusions, 2 controls). Data on lesion crossing, flow deceleration and macroembolization were recorded. Filter membranes were evaluated with @entity4653 ( @entity4653 ). RESULTS: System delivery was successful in all @entity1 . @entity75 crossing was feasible in four of six stenoses; predilatation was required in two of six. Marked flow deceleration was recorded in six @entity1 . Emboli next to the filter were detected in each @entity1 with concentric plaques, but could not reliably be removed with the filter. Downstream macroembolization was also present in all @entity1 with concentric stenoses, but in none with chronic occlusion. None of the @entity1 had clinical signs of @entity63 . @entity4653 analysis demonstrated only small particles on control group filters and non-obliterating fibrinous conglomerates on filters used in chronic occlusion. Substantial obliteration was seen on several filters used in stenotic lesions. CONCLUSION: Microembolization of fibrin aggregates is a common incident in balloon angioplasty of femoropopliteal stenoses. Macroembolization occurred more frequently than previously reported. The use of @entity887 protection filters aided in the detection but not in the @entity999 .
