光学相干断层成像技术在脑血管造影评估中的应用

Application of optical coherence tomography in the cerebral angiography

血管内光学相干断层成像(optical coherence tomography,OCT)作为一种新兴的血管内成像技术,其临床应用价值在近10年的不断探索中得到了肯定。OCT因其具有超高的分辨率,可以清晰地显示动脉狭窄病变细微的形态特征,帮助选择治疗方案,指导支架置入,在支架置人术后评估支架一血管关系和新生内膜的覆盖情况,及时发现支架术后早、晚期并发症。近年来也有一系列研究探讨了OCT在脑血管造影及颅内外动脉支架术中的评估价值,我们就此做一综述。

As an emerging intravascular imaging technology,intravascular optical coherence tomography (OCT)has been recognized for its clinical application value in the continuous exploration of the past decade.With its high resolution,OCT can clearly display the subtle morphological features of arterial stenosis lesions,help select treatment options,guide stent placement,and evaluate stent-vessel relationship and neo-intimal coverage after stent implantation for timely detecting early and late complications after stent placement.In recent years,a series of studies have also explored the value of OCT in the evaluation of cerebral angiography and intracranial and extracranial artery stent placement.We made a review of this topic.
