The Novel use of Infrared Thermal Imaging as an Adjunct for the Management of Haemodialysis Access Induced Distal Ischaemia

Abstract

Introduction Haemodialysis access-induced distal ischaemia (HAIDI) whilst unusual may be a difficult complication to diagnose and manage particularly in patients with small vessel disease. Infrared thermal imaging (IRTI) has been used for several decades to monitor cutaneous temperature distribution and has been used in medical applications. The use of IRTI in HAIDI is attractive as it can be used as a non-invasive measure of tissue perfusion. Method and Results To assess the applicability of IRTI in HAIDI, three cases were assessed and are described. IRTI was well tolerated and provided useful clinical information in all three cases, which was confirmed with further studies. Conclusions This small case series reports on the successful use of infrared thermal imaging in the diagnosis and management of possible HAIDI and may support wider study and use.
