Detection of Dialysis Access Induced Limb Ischemia by Infrared Thermography in Children

摘要: High arteriovenous fistula (AV fistula) blood flow may impair distal limb perfusion and cause irreversible ischemic damage. Since tissue temperature reflects perfusion, we tried to assess using an infrared camera. We examined all 12 patients with AV in our dialysis unit. Seven were pediatric aged 11.0–18.9 years (mean 14.9 years) five adults 26.9–62.1 years 38.6 years). Infrared thermal imaging (thermography) of their hands was performed after the completion regular sessions. In each patient, spot fingertip on both assessed separately, three measurements being for measuring point. The mean fingertips calculated hand results compared. A statistically significant difference (P < 0.05) indicated insufficiency. Perfusion also by inspecting visualized distribution image. Finally, compared clinical findings relevant patients. 8/12 (66.7%), significantly lower side (P < 0.05). Only 4/12 (33.3%) had symptoms, detected thermography. Abnormal more frequent elderly Although realize that diagnosis steal syndrome is primarily clinical, thermography might be a safe, noninvasive, cheap tool timely detection children at risk developing symptoms ischemia.
