Use of PEAK PlasmaBlade in implant-based breast reconstruction and radiotherapy: new strategy to reduce complications.

BACKGROUND

Implant-based breast reconstruction in the setting of radiotherapy often leads to higher complications rates (mainly capsular contracture and wound dehiscence) and poor cosmetic outcomes. We hypothesized that the combination of pulsed-electron avalanche knife (PEAK) PlasmaBlade (a pulsed radiofrequency electrosurgery) and acellular dermal matrix Veritas® in postmastectomy radiotherapy implant-based breast reconstruction could result in lower complications rate, better reconstructive results, and patient satisfaction.

METHODS

A prospective observational study focused on the use of PEAK PlasmaBlade in implant-based breast reconstruction and radiotherapy was carried out in the Plastic Reconstructive Surgery Unit at Fondazione IRCCS Istituto Nazionale Tumori Milano between December 2017 and 2019 (2017-2018: enrollment; 2018-2019: follow-up). Patient demographics were queried and complication rates and patient and surgeon satisfaction were assessed.

RESULTS

A total of 88 patients were enrolled; 2 patients received bilateral reconstruction, leading to a total of 90 procedures. Sixty-two women received contralateral symmetrization. Seroma was the most frequent minor complication (8.8%); implant exposure was the most recorded among major complications (5.5%). Preoperative lipofilling was the most substantial protective factor for preventing complications (p < 0.001). A significant association between capsular thermal damage thickness and the type of electrosurgery used (traditional electrosurgery vs PEAK PlasmaBlade) was observed, with lower values with PEAK PlasmaBlade (p < 0.0001).

CONCLUSIONS

Our protocol results in low rates of surgical complications and a high level of patient and surgeon satisfaction although longer follow-up is needed.
