Optical coherence tomography (OCT) is an imaging technique analogous to ultrasound, using light instead of sound waves. 1 It utilises interferometry to map the reflectivity of light in terms of depth to provide high-resolution, cross-sectional images of the internal tissues. 2 Upon its first realisation by Huang et al for imaging of the retina and the coronary arteries in 1991, 3 it was initially utilised in the field of ophthalmology. 4,5 Owing to its high resolution of images, it was subsequently applied in cardiology, 6 dermatology, 7 oncology, 8 dentistry, 9 as well as endoscopic visualisation of hollow organs like the gastrointestinal tract 10 and the airway. 11 Atherosclerosis is a prevalent and disabling disease with occlusion and stenosis of the systemic arteries other than cerebral and coronary circulation. 12 Despite the evolving pharmacological intervention in symptomatic control, revascularisation remains the treatment of choice in chronic lower limb occlusive disease, presenting with short distance claudication, rest pain, arterial
