Percutaneous transluminal atherectomy: preliminary results.

Percutaneous transluminal atherectomy with the Simpson atherectomy catheter was performed in 10 patients with 14 severe atheromatous stenoses of the femoropopliteal arteries. Removal of plaque material with restoration of vessel patency was successful in all patients without complication. Further clinical follow-up will have to determine whether the recurrence rate of stenoses will be lower with this method than with conventional balloon angioplasty.
