Protocol Adaptation of Optical Coherence Tomography in Lower Limb Arteries Revascularization.

In lower limb arteries, assessment of stent apposition and/or the single opening of the diseased artery remains poor since this relies on 2-dimensional angiogram. Extrapolating experience gained with coronary arteries, optical coherence tomography (OCT) could provide 3-dimensional reconstructions of the arterial wall and the stent implanted. A modified protocol of OCT acquisition, which usually includes large amount of iodine contrast flush, is presented here in 3 patients with long and complex occlusion of the superficial femoral artery. Its potential benefits and wider application to improve patient outcomes are discussed.
