The purpose of this study was with a simple clinical setting to compare skin temperature changes in the feet before and after revascularization and to identify possible correlation between ankle brachial index (ABI) and toe pressure (TP) values and foot skin temperature patient with and without diabetes.
Forty outpatient clinic patients were measured ABI, TP, and the skin temperature using infrared thermography (IRT) at the foot before and after revascularization. Patients in the revascularization group were divided into subgroups depending on whether they had diabetes or not and a wound or not.
There were clear correlation between increase of ABI and TP and increase of the mean skin temperature on the feet after revascularization. The temperature was higher and the temperature change was greater among patients with diabetes. Side-to-side temperature difference between the revascularized feet and contralateral feet decreased after treatment. The mean temperature was higher in the feet with wound whether patient had diabetes mellitus or not.
The simple, prompt, and noninvasive IRT procedure showed its potential as a follow-up tool among patients with diabetes or peripheral arterial disease and previous lower limb revascularization.
本研究旨在通过简单的临床环境，比较血管重建前后足部皮肤温度的变化，并确定有或无糖尿病的患者的踝肱指数（ABI）和趾压（TP）值与足部皮肤温度之间的可能相关性。
40 名门诊患者在血管重建前后使用红外热像仪（IRT）测量足部的 ABI、TP 和皮肤温度。将血管重建组的患者根据是否患有糖尿病、是否有伤口进行分组。
血管重建后，ABI 和 TP 的升高与足部平均皮肤温度的升高有明显相关性。糖尿病患者的温度更高，温度变化更大。治疗后，患侧与对侧足部的温差减小。无论患者是否患有糖尿病，有伤口的足部温度均较高。
简单、迅速、无创的 IRT 程序显示了其作为糖尿病或外周动脉疾病和下肢先前血管重建患者随访工具的潜力。
