Here we report the application of optical frequency domain imaging (OFDI), a new optical coherence tomography device, for intravascular visualization in the treatment of a recanalized unruptured internal carotid artery aneurysm that was treated initially by stent-assisted coil embolization.
OFDI revealed malapposition of the stent and lack of neointimal growth at the aneurysm neck, which was treated by deployment of a Pipeline Embolization Device to overlap the stent. An angiogram performed 1 year after the procedure revealed perfect healing of the aneurysm, and OFDI clearly demonstrated good stent apposition and total endothelialization over the aneurysm neck.
OFDI/OCT appears to be a useful diagnostic tool for evaluating stent-strut apposition over the vessel wall and the grade of neointimal endothelialization across the neck of the aneurysm in aneurysmal recanalization.
本研究报告了应用光学相干断层扫描（OCT）血管内可视化技术，对支架辅助弹簧圈栓塞治疗后再通的未破裂颈内动脉动脉瘤进行治疗。
OCT 显示支架贴壁不良，瘤颈处无新生内膜生长，因此采用 Pipeline 栓塞装置重叠支架以覆盖瘤颈。术后 1 年行血管造影显示动脉瘤完全愈合，OCT 清晰显示支架在瘤颈处贴壁良好，完全内皮化。
OCT 似乎是一种有用的诊断工具，可用于评估支架在血管壁上的贴壁情况，以及瘤颈处新生内膜内皮化程度。
