Abstract
Introduction

During oncoplastic procedures, the vascularization and perfusion of the skin flaps is modified, thus increasing the possibility of skin necrosis.

The objective of this study is to evaluate the effectiveness of indocyanine color green angiography (ICG-A) to determine intraoperative skin necrosis after oncoplastic surgery or skin-sparing or nipple-skin sparing mastectomy (NSSM).

Patients and method

Prospective observational study to evaluate the sensitivity, specificity and positive and negative predictive values ​​of the ICG-A in women with high-risk breast cancer.

Results

98 women and 156 breasts were included in the study. A total of 20 women (20.4%) presented an image of ischemia in the ICG-A. 21 women (21.4%) presented ischemic events in the postoperative period, 71.4% of these events had been detected in the third ICG-A. Three of these patients (3.1%) presented a serious complication that required reintervention. The sensitivity and specificity of the ICG-A was 71.4% and 93.5%, respectively.

Conclusions

ICG-A has high specificity and negative predictive value for detecting areas of low perfusion. In breast units with highly complex surgery, it can be useful to plan extreme surgeries and identify skin areas of low perfusion.

Resumen
Introducción

Durante los procedimientos oncoplásticos se modifica la vascularización y perfusión de los colgajos cutáneos, incrementando así la posibilidad de necrosis cutánea.

El objetivo de este estudio es evaluar la eficacia de la angiografía con verde de indocianina (A-VIC) para determinar necrosis cutánea intraoperatoria tras una cirugía oncoplástica o una mastectomía preservadora de piel o piel-pezón (MPPP).

Pacientes y método

Estudio prospectivo observacional para evaluar la sensibilidad, especificidad y valores predictivos positivo y negativo de la A-VIC en mujeres con cáncer de mama y alto riesgo.

Resultados

Se incluyeron 98 mujeres en el estudio y 156 mamas. Un total de 20 mujeres (20,4%) presentaron imagen de isquemia en la A-VIC. 21 mujeres (21,4%) presentaron eventos isquémicos en el postoperatorio, el 71,4% de estos eventos habían sido detectados en la tercera A-VIC. Tres de estas pacientes (3,1%) presentaron una complicación grave que precisó reintervención. La sensibilidad y especificidad de la A-VIC fue de 71,4% y 93,5%, respectivamente.

Conclusiones

La A-VIC tiene una alta especificidad y valor predictivo negativo (VPN) para detectar áreas de baja perfusión. En unidades de mama con cirugía de alta complejidad puede ser útil para planificar cirugías extremas e identificar áreas cutáneas de baja perfusión.
