Indocyanine green angiography guidance for vascular preservation in skin and nipple sparing mastectomy.

PURPOSE: The skin and/or nipple-sparing approach has become an oncologically sound and desirable choice for women choosing mastectomy. Indocyanine green (ICG) perfusion imaging has been shown to reduce ischemic complications in mastectomy skin flaps. Immediate reconstruction requires a well-vascularized skin flap capable of tolerating full expansion. Identification of the perforating subcutaneous vessels to the skin envelope may allow for better and more consistent blood vessel preservation and flap perfusion. METHODS: The authors conducted an institutional review board-approved prospective study with 41 patients to assess the feasibility of using ICG perfusion imaging to visualize, cutaneously map, and preserve the vessels that supply the skin flap and nipple-areolar complex. For each patient, the number of vessels initially mapped, the number of vessels preserved, the extent to which each vessel was preserved, and the proportion of the flap with adequate perfusion (as defined by the SPY-Q > 20% threshold) was recorded and analyzed. RESULTS: Vessels were able to be identified and marked in a high majority of patients (90%). There was a moderate linear relationship between the number of vessels marked and the number preserved. Successful mapping of vessels was associated with lower rates of wound breakdown (p = 0.036). Mapping and preserving at least one vessel led to excellent flap perfusion (> 90%). No increase in complications was observed from utilizing ICG angiography preoperatively. CONCLUSION: This prospective study using preoperative ICG perfusion mapping demonstrated safety, feasibility, and good prognostic outcomes. LEVEL OF EVIDENCE: III.

Pedicle Selection and Design in Reduction Mammaplasty: The Role of Preoperative Fluorescence Imaging.

BACKGROUND: Breast reduction has a wide selection of pedicles but often relies on the surgeon's preference and experience. Necrosis of the nipple-areola complex (NAC) is a catastrophic complication of breast reduction surgery. OBJECTIVES: To solve the above problem objectively, we applied fluorescence imaging technology to the pedicle selection and design of breast reduction surgery for the first time, so that the dominant vessels of the NAC were included in the designed pedicle. METHODS: We retrospectively enrolled 120 patients with breast reduction (a total of 239 breasts). We compared 60 patients who underwent breast reduction without fluorescence imaging for pedicle selection (Group A) with 60 patients who underwent pedicle selection with fluorescence imaging (Group B). The NAC blood supply was monitored after the operation. RESULTS: In this study, 60 Group A cases (119 breasts) and 60 Group B cases (120 breasts) were analyzed. There were no statistically significant differences in patient demographic data or intraoperative resection weights. There were 7 cases of NAC necrosis in Group A (1 case of complete necrosis and 6 cases of partial necrosis), while no NAC necrosis occurred in Group B. There was a significant difference in the rate of NAC necrosis between the 2 groups. CONCLUSIONS: Preoperative fluorescence imaging can guide the selection and design of breast reduction, significantly reducing postoperative NAC blood supply obstacles and necrosis.

Raynaud's phenomenon of the nipple during breastfeeding: A case series. / Fenómeno de Raynaud en el pezón durante la lactancia: serie de casos.

Raynaud's phenomenon consists of excessive contraction of the blood vessels in response to various stimuli; although it usually affects the extremities, other locations are less frequently involved. This study focused on describing the characteristics of a series of women with Raynaud's phenomenon of the nipple. Through medical record review and direct communication with patients, data from 12 women diagnosed with Raynaud's phenomenon of the nipple between 2016 and 2023 were collected and analyzed. The following variables were assessed: age, symptoms, triggering factors, treatment, and duration of symptoms. In this case series, Raynaud's phenomenon of the nipple in breastfeeding women was more common among primiparous women around 10 days after delivery; pain was severe and, in most cases, improved with local and/or drug treatment, and did not limit the duration of breastfeeding.

El fenómeno de Raynaud consiste en la contracción excesiva de los vasos sanguíneos en respuesta a diversos estímulos y, si bien suele comprometer las extremidades, existen otras localizaciones menos frecuentemente afectadas. Este trabajo se enfoca en describir las características de una serie de mujeres con fenómeno de Raynaud en el pezón. Mediante revisión de historias clínicas y comunicación directa con las pacientes, se recopilaron y analizaron los datos de 12 mujeres con Raynaud del pezón entre 2016 y 2023. Se evaluaron variables como edad, síntomas, desencadenantes, tratamientos y duración de los síntomas. En esta serie de casos, el fenómeno de Raynaud del pezón en mujeres lactantes se manifestó con mayor frecuencia en primigestas alrededor del décimo día posparto; el dolor fue intenso, en la mayoría mejoró con tratamientos locales y/o farmacológicos, y no limitó la duración de la lactancia materna.

Mastoplastia redutora: manobra tática de Silveira Neto mofidicada para ascençäo do complexo aréolo-mamilar / Reduced mastoplasty: modified Silveira Neto's tactical maneuver for ascension of the nipple-areola complex

Fazendo uma revisäo sobre técnicas de transposiçäo de mamilo e aréola, selecionams a técnica de Sileira Neto, porque permite maior suprimento sangüíneo, maior segurança e facilidade de manipulaçäo. Este método apresenta o melhor resultado em relaçäo ao contorno natural do corpo
