    ABSTRACT Introduction: Placement of breast implants is the most commonly used form of breast reconstruction. Despite its advantages, infection of the implant, either in the tissue expander or mammary prosthesis, can be a significant problem, including the need to remove it. The objective of this work is to evaluate the infection rate of breast implants used for breast reconstruction in patients submitted to surgery at the Cancer Institute of the State of São Paulo (ICESP), as well as its correlation with clinical, oncological, and surgical factors. Patients and methods: This is a retrospective study on 120 patients submitted to breast reconstruction with breast implants at the ICESP from February 2009 to March 2010. Results: The infection rate (24.3%) was statistically related to immediate reconstruction (88.9%), diabetes mellitus (25%), body mass index >30 (52.8%), systemic arterial hypertension (52.8%), and skin injury due to mastectomy (27.8%). Of the infected implants, 44% were removed, most of which were expanders placed during immediate reconstruction. Conclusions: Breast reconstruction with implants is the safest and most effective form of treatment. However, consideration should be given to patients who are prone to the development of infection, in order to optimize its prevention and attempt to perform its treatment at an early stage.

    Serratus anterior muscle flap as a salvage procedure in exposed implant-based breast reconstruction
    (2019) MONTAG, Eduardo; OKADA, Alberto; ARRUDA, Eduardo G. P.; MUNHOZ, Alexandre M.; BUSNARDO, Fabio F.; GEMPERLI, Rolf
    BACKGROUND: Implant-based breast reconstruction (IBR) is the most common approach to reconstruct mastectomy deffects. Infection following breast reconstruction can be devastating and lead to loss of the reconstruction due to the need of implant removal. The serratus anterior muscle flap is widely used during breast reconstruction to provide coverage of the implant/expander. METHODS: We present the application of the serratus anterior muscle flap to treat implant exposure after breast reconstruction. CASES PRESENTATION: Two patients who experienced implant exposure after breast reconstruction were successfully treated with partial capsulectomy, pocket irrigation and implant coverage with a serratus anterior muscle flap. RESULTS: No post operative complications have been observed while implant retention was achieved in both cases. CONCLUSIONS: The serratus anterior muscle flap is an option to treat implant exposure following breast reconstruction in selected cases. This flap could be used to prevent implant exposure in critical cases. (C) 2019 Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.

    Influência do posicionamento do retalho linfonodal vascularizado na resposta ao tratamento cirúrgico do linfedema secundário ao câncer de mama.

    ABSTRACT Objective: to evaluate the initial therapeutic experience of transplantation of vascularized lymph nodes in patients with lymphedema of the upper limbs secondary to the treatment of breast cancer, and to verify if the positioning of the transplant influences the surgical result. Methods: we conducted a prospective, comparative test of two therapeutic modalities, with 24 patients with lymphedema of the upper limb after breast cancer treatment, classified as grades 2 and 3, according to the International Lymphedema Society. The two types of procedures performed were: 1) total breast reconstruction with - deep inferior epigastric perforator (DIEP) flap associated with lymph node flap, in patients with no previous breast reconstruction or loss of previous reconstruction (axillary positioning); 2) isolated inguinal lymph node flap performed in patients with completed breast reconstruction or without the desire to perform the breast reconstruction (wrist positioning). Results: the reduction percentage of the affected limb volume was 20.1% (p=0.0370). The number of infectious episodes (cellulites) also decreased significantly, from 41% in the preoperative period to 12.5% in the postoperative one (p=0.004). There were no differences between the proximal and distal groups. Conclusion: the transplantation of lymph nodes positively affected the postoperative evolution of patients with lymphedema secondary to breast cancer. We observed no differences in relation to flap positioning.
