Effectiveness of infrared thermography in the diagnosis of deep vein thrombosis: an evidence-based review

Venous thromboembolism is a serious medical, social, and economic problem. A number of treatment options exist to decrease mortality and morbidity in patients with deep vein thrombosis (DVT). An accurate and timely diagnosis of this condition is important to improve immediate and long-term prognosis. The standard diagnostic algorithm implying assessment of the clinical probability of the disease, d-dimer test, and venous duplex ultrasound is not optimal. Infrared thermography is a relatively new diagnostic modality under clinical investigation for various medical conditions. This study aims to review the published evidence on infrared thermography as a possible alternative tool in DVT diagnosis. The authors conclude that infrared thermography is still an experimental diagnostic tool for patients with DVT, and requires more clinical research evidence to support theoretical advantages and suggest a possible clinical application.
