Femoropopliteal Balloon Angioplasty vs. Bypass Surgery for CLI: A Propensity Score Analysis

Abstract Objectives To compare the outcomes of femoropopliteal percutaneous transluminal angioplasty (PTA) and bypass surgery for critical limb ischaemia (CLI). Design The study is retrospective in nature. Materials and methods This study included 858 consecutive patients, who underwent femoropoplit...

Zusammenfassung:	Abstract Objectives To compare the outcomes of femoropopliteal percutaneous transluminal angioplasty (PTA) and bypass surgery for critical limb ischaemia (CLI). Design The study is retrospective in nature. Materials and methods This study included 858 consecutive patients, who underwent femoropopliteal revascularisation for CLI at Helsinki University Central Hospital during 2000–2007. As many as 517 patients (60%) underwent PTA and 341 (40%) bypass surgery. Propensity score analysis was used for risk adjustment in multivariable analysis and for one-to-one matching. Results In the overall series, PTA had poorer long-term results than bypass (5-year leg salvage, 78.2% vs. 91.8%, p
