Optical coherence tomography in peripheral arterial disease: A systematic review

Abstract

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

Superior mesenteric artery terminal branch stent failure studied by optical coherence tomography

“…Optical coherence tomography (OCT) represents a valuable imaging modality in the percutaneous intervention of the coronary arteries, guiding stent implantation and studying mechanisms of stent failure 1 . Prior studies suggested the feasibility of OCT in peripheral artery disease, 2 although its usefulness in the percutaneous intervention of the splanchnic arteries has not been well defined. Hereby, we present a case of stent failure of the terminal branch of the superior mesenteric artery (SMA) studied by OCT imaging.…”
