An analysis of free flap failure using the ACS NSQIP database. Does flap site and flap type matter?

Abstract

Risk factors for free flap failure differ based upon flap site and flap type. Prolonged operative time is an independent risk factor for the failure of free flaps used for breast reconstruction. An ASA classification ≥3 is associated with the failure of free muscle based flaps. Our findings identify actionable areas that may help to improve free flap success.
