De novo superficial femoropopliteal artery lesions: peripheral cutting balloon angioplasty and restenosis rates--randomized controlled trial.

Purpose: To prospectively determine, in a randomized controlled trial, whether cutting balloon angioplasty (CBA) yields superior morphologic and clinical outcomes at 6 months compared with the 6-month outcomes after conventional percutaneous transluminal angioplasty (PTA) in patients with short de novo superficial femoropopliteal artery (SFA) lesions.

Materials And Methods: This study was approved by the ethics committees of the two participating centers, and informed consent was obtained from all patients. The authors randomly assigned 43 patients (26 men, 17 women; median age, 69 years) who had 5 cm or shorter de novo SFA lesions in association with intermittent claudication or chronic limb ischemia to undergo CBA or PTA.
