ABSTRACT

We evaluated the concordance of the thermographic camera and Doppler ultrasound for the location of perforators in flaps. We conducted an observational, analytical, prospective, and longitudinal study, which included patients scheduled for elective surgery with perforator flaps, between January 2023 and February 2024. The detection and evaluation of perforators in the flaps, we planned, was carried out using the thermographic camera and conventional Doppler equipment, and the accuracy of both was subsequently verified, trans operatively with direct visualization. The identification of perforators with each equipment was carried out in 26 flaps. The anatomical areas most frequently operated on were: thoracic limb (10) (38.5%) and pelvic limb (10) (38.5%), followed by head and neck (4) (15.4%) and thorax (2) (7.7%). The thermographic camera detected a greater number of perforators in 57% of the cases and the rest of the time it was the same as the Doppler. Regarding the prediction of the emergence of the perforator to the cutaneous island, thermography showed a smaller margin of error in 50% of the cases and, in the rest, it was equal to the Doppler equipment. We conclude that the use of thermography for the detection of perforators is a safe, reproducible and highly reliable method. Our study proved that the thermographic camera detects a greater number of perforators in the area to be intervened, compared to the conventional Doppler equipment; this difference being statistically significant.
