Background: The selection of the best vessels is of utmost importance in reconstruction surgeries. This will reduce operative time, decrease complication rates, and ensure a better overall result. It is observed that dynamic infrared thermography (DIRT) has been increasingly used in reconstructive microsurgery to evaluate flap viability and locate perforators. DIRT measures the rate and patterns of rewarming after cooling. The sensor detects heat irradiation and forms a thermogram where the temperature of each spot can be recognized. This article aims to conduct a systematic review of the clinical applications of DIRT imaging in plastic surgery.
Methods: The search was performed in MEDLINE, LILACS, Cochrane, and Scielo databases using the following terms: “thermography”, “thermometry”, “surgical flaps”, “reconstructive surgical procedures” and “microsurgery”. Articles published from January 2006 to October 2021 were included. The primary search provided 115 matches in MEDLINE, 0 in LILACS, 6 in Cochrane, and 0 in Scielo. After removing duplicates, 115 articles were considered.
Results: After reading the titles and abstracts and removing duplicates, a total of 38 publications were found. These were read in full and evaluated against the inclusion and exclusion criteria. After full reading and analysis, a total of 25 publications met the inclusion criteria.
Conclusion: The use of DIRT shows promise for flap monitoring in reconstructions in
Plastic Surgery.
