颈内动脉系统供应脑的前循环.颈内动脉粥样硬化、颈动脉血管炎以及颈内动脉夹层等病变均会导致血管腔狭窄、斑块破裂及继发血栓的形成,继而引起缺血性脑血管病.本文介绍颈动脉系统光学相干断层成像(optical coherence tomography, OCT)成像方法、OCT对颈动脉病变的评价方法以及在颈动脉支架置入过程中的应用,并对OCT技术在颈动脉系统中的应用优劣势和前景进行展望.%Internal carotid artery system supplies the anterior circulation of the brain. Internal carotid atherosclerosis, carotid vasculitis and carotid artery dissection and other diseases can lead to vascular stenosis, plaque rupture and secondary thrombosis formation, hence to cause ischemic cerebrovascular disease. This article describes the progress of optical coherence tomography (OCT) application in the internal carotid artery. The mechanisms of OCT, OCT technique in carotid artery, usefulness of OCT in evaluating carotid artery lesion were introduced respectively. The advantages, limitations, and possible future developments were also discussed.
