Treatment of complex superficial femoral artery lesions with PolarCath cryoplasty.

Use of cryoplasty in patients with severely symptomatic (Rutherford category > or =3) superficial femoral artery (SFA) disease has not been systematically evaluated. From August 2006 to October 2007, 27 consecutive, severely symptomatic patients with 39 lesions in 36 limbs underwent SFA cryoplasty using the PolarCath at 2 centers. Mean age was 74 +/- 12 years and 48% were men; 41% had diabetes, 59% had coronary artery disease, and 61% had complex lesions (ostial, calcified, chronic total occlusion, in-stent restenosis, or length > or =150 mm).
