Abstract
Prepectoral breast reconstruction offers esthetic and recovery advantages but may be more vulnerable to complications due to the absence of muscular coverage. This study examined the clinical course of patients with failed prepectoral implant reconstruction. All consecutive prepectoral reconstructions performed between March 2017 and July 2022 at a single tertiary center were reviewed. Of 239 reconstructions, 42 (17.5%) ultimately failed, most commonly due to infection (50%). Sixteen patients (38%) underwent definitive reconstruction with a median interval of 379 days (IQR 249) from initial surgery to final reconstruction. The most common secondary reconstruction modalities were implant-based reconstruction (31%) and free-tissue transfer (31%). On multivariate analysis, increasing age, higher body mass index (BMI), and prior radiation were independently associated with implant loss. Failure of salvage after prepectoral reconstruction remains a major challenge and often results in delayed or abandoned reconstruction, highlighting the need for careful patient selection.
