The use of infrared thermal imaging as a marker of tissue perfusion and predictor of arteriovenous fistula outcomes

[摘要] The gold standard of vascular access is the arteriovenous fistula (AVF).Unfortunately it is associated with high rates of failing to mature. Therefore the ability to predict AVF outcomes would change clinical practice. Predictive markers of AVF outcomes were assessed in chapter 2. The literature and our study showed numerous contradictions.In chapter 3 we assessed a multifactorial approach with a systematic review on predictive models of maturation. The review found few models and the disparity between each one limits the development of a unified model. Recent development in infrared thermal imaging (IRTI) technology has made it portable and easy to use. In Chapter 4, we proved that IRTI is a valid and user-friendly method of measuring skin temperature and is comparable to traditional methods of thermometry. IRTI can be used to quantity reactive hyperaemia following a vascular occlusion test (chapter 5). In Chapter 6 we showed that IRTI is an accurate tool in predicting AVF outcome. It was shown to have superiority to intra-operative thrill and other independent patient factors. In conclusion IRTI has a definite role in patients with vascular access. There is also potential for its use in patients with other conditions such as peripheral vascular disease.
