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 A-VIC 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.
