This study examines the ability of infrared thermography (IRT) to distinguish vasculopathy patients (VP) from healthy controls (HC) during post-occlusive reactive hyperemia (PORH). Three VP and three HC participated in the study. The experimental procedure included a 3-min baseline, a 5-min occlusion at 50 mmHg above the systolic pressure, and a 3-min reperfusion. During PORH, HC had a larger temperature fluctuation of the fingertips from the baseline (1.22 ± 0.97°C) compared to VP (0.53 ± 0.57°C). Accordingly, color Doppler ultrasound assessed differences in the arterial resistivity index between the two groups. These findings, albeit preliminary, could facilitate IRT employment during POHR.

Abstract
This study examines the ability of infrared thermography (IRT) to distinguish vasculopathy patients (VP) from healthy controls (HC) during post-occlusive reactive hyperemia (PORH). Three VP and three HC participated in the study. The experimental procedure included a 3-min baseline, a 5-min occlusion at 50 mmHg above the systolic pressure, and a 3-min reperfusion. During PORH, HC had a larger temperature fluctuation of the fingertips from the baseline (1.22 ± 0.97°C) compared to VP (0.53 ± 0.57°C). Accordingly, color Doppler ultrasound assessed differences in the arterial resistivity index between the two groups. These findings, albeit preliminary, could facilitate IRT employment during POHR.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
