Angioplasty and elective stenting of de novo versus recurrent femoropopliteal lesions: 1-year follow-up.

Purpose:To investigate patency rates after percutaneous transluminal angioplasty (PTA) and PTA plus elective stenting in de novo versus recurrent femoropopliteal lesions.Methods:The data were collected from a prospective registry including 533 consecutive patients (284 men; median age 71 years, interquartile range [IQR] 72–78) with severe claudication (n=387) or critical limb ischemia (n = 146) who underwent femoropopliteal percutaneous interventions during a 36-month period. PTA was used to treat 357 de novo and 99 recurrent lesions; PTA plus elective stent implantation was performed in 58 de novo and 19 recurrent lesions. Patients were followed for a median 12 months (IQR 7–14) using color duplex sonography. Rates of restenosis (≥50%) were compared by multivariate analysis.Results:Overall primary technical success was achieved in 517 (97%) patients; 31 (6%) periprocedural complications were encountered. Restenosis occurred in 213 (40%) patients after a median 6 months (IQR 4–7). Twelve-month patency aft...
