- Influência do posicionamento do retalho linfonodal vascularizado na resposta ao tratamento cirúrgico do linfedema secundário ao câncer de mama.(2019) MONTAG, Eduardo; OKADA, Alberto Yoshikazu; ARRUDA, Eduardo Gustavo Pires; FONSECA, Alexandre Siqueira; BROMLEY, Miluska; MUNHOZ, Alexandre Mendonça; BUSNARDO, Fábio Freitas; GEMPERLI, RolfABSTRACT 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.
- Influence of advanced age on postoperative outcomes and total loss following breast reconstruction: a critical assessment of 560 cases(2018) MATSUMOTO, WALTER KOITI; MUNHOZ, ALEXANDRE MENDONÇA; OKADA, ALBERTO; MONTAG, EDUARDO; ARRUDA, EDUARDO GUSTAVO; FONSECA, ALEXANDRE; FERRARI, ORLANDO; BRASIL, JOSÉ AUGUSTO; PRETTI, LIA; FILASSI, JOSÉ ROBERTO; GEMPERLI, ROLFABSTRACT Objective: to evaluate the role of age in the risk of postoperative complications in patients submitted to unilateral breast reconstruction after mastectomy, with emphasis on total reconstruction loss. Methods: we conducted a retrospective study of patients submitted to breast reconstruction, whose variables included: oncological and reconstruction data, postoperative complications, including loss of reconstruction and complications of surgical wound. We divided the patients into two groups, according to the classification of the Brazilian National Elderly Policy and the Statute of the Elderly: young (age <60 years) and elderly (60 years or more). We also grouped them according to the World Health Organization classification: young people (age <44 years), middle age (45-59 years); elderly (age 60-89 years) and extreme advanced age (90 years or older). We applied the surgical risk classification of the American Society of Anesthesiologists to investigate the role of the preoperative physical state as a possible predictor of complications. Results: of the 560 patients operated on, 94 (16.8%) were 60 years of age or older. We observed a local complication rate of 49.8%, the majority being self-limited. The incidences of necrosis, infection and dehiscence were 15.5%, 10.9% and 9.3%, respectively. Patients older than 60 years presented a chance of complication 1.606 times greater than the younger ones. Forty-five (8%) patients had loss of the reconstruction; there was no statistically significant difference in the mean age of the patients who presented this result or not (p=0.321). Conclusion: in selected patients, breast reconstruction can be considered safe; most documented complications were limited and could be treated conservatively.
