Abstract

Objective: To evaluate the effectiveness of Dynamic Infrared Thermography (DIRT) in identifying arterial branches supplying the nipple-areola complex (NAC) prior to reduction mammoplasty, and to investigate its role in assessing NAC perfusion intraoperatively and postoperatively.
Methods: A prospective cross-sectional descriptive study was conducted on 20 female patients with severe or gigantomastia undergoing breast reduction surgery. Preoperative assessments included DIRT, color Doppler ultrasound, and contrast-enhanced computed tomography (CT) angiography. DIRT was also performed intraoperatively and postoperatively.
Results: An average of 2.25 arterial branches per breast were identified using DIRT, consistent with Doppler and higher than CT angiography (1.80). The highest anatomical concordance between DIRT and Doppler reached 78.26%. The detected arterial branches had diameters ≥ 0.8 mm and depths ≤ 64.40 mm. Simple linear regression analysis of Level 1 concordant branches between DIRT and Doppler demonstrated a statistically significant positive correlation between blood flow velocity and thermal recovery rate. One case of partial NAC hypoperfusion was recorded; no complete NAC necrosis was observed.
Conclusion: DIRT is a safe, non-invasive technique with promising potential for evaluating NAC perfusion before, during, and after reduction mammoplasty. Further studies with larger sample sizes are needed to determine its clinical accuracy and detection thresholds.
