Микроциркуляция глазного дна после реваскуляризации внутренней сонной артерии в раннем послеоперационном периоде

Abstract

Purpose. To study the effect of ICA revascularization on the parameters of the fundus microvasculature in patients with clinically significant ICA stenosis in the early postoperative period. Material and methods. Thirty-two patients with hemodynamically significant stenosis (≥ 75 %) of the right or left internal carotid artery (ICA) were studied using OCT angiography. Results. According to the results of OCT angiography before the revascularization procedure, there were no significant differences in hemodynamic parameters in the eyes on the side of the stenotic and non-stenotic ICA. In the early postoperative period (3–7 days), an increase in blood flow density and vascular density at the level of the superficial and deep plexuses in the macular region was observed in the ipsilateral eyes (p ≤ 0.05). In the contralateral eyes, after ICA revascularization, there was a partial improvement in microcirculation parameters according to OCT angiography (p ≤ 0.05). Peripapillary blood flow density and vascular density did not change significantly in both eyes. Conclusion. In patients with clinically significant ICA stenosis, ICA revascularization by stenting or CAEA contributed to an effective improvement of retinal microcirculation in both eyes. Keywords: optical coherence tomography-angiography, stenting of the internal carotid artery, revascularization, eye microcirculation.
