Purpose: To evaluate prospectively the Pullback Atherectomy Catheter (PAC) in terms of its technical success and 1-year patency in the treatment of lower limb vascular disease. Methods: Thirty-nine PAC procedures were performed in 34 patients to treat atherosclerotic disease (occlusive in 51%) of the femoropopliteal arteries, including four cases of graft neointimal hyperplasia and three dissection flaps. Follow-up was by ankle<+>-<+>brachial indices at 24 hr and 1 month, and arteriography at 6 and 12 months. Results: Technical success was achieved in 38 of 39 procedures (97.4%). There was a reduction in mean stenosis from 89.4% to 12.1%, but 69.2% of procedures required additional balloon dilatation to achieve an adequate arterial lumen. Complications followed 15.4% of procedures, a third of which required surgery. Conclusion: The PAC is an easy and relatively safe catheter to use, but does not provide a satisfactory arterial lumen without additional percutaneous transluminal angioplasty (PTA). It proved to be effective, however, in the treatment of graft neointimal hyperplasia and in the resection of obstructive intimal flaps following PTA.
