OCT对冠状动脉介入术后即刻支架周围组织结构改变的评价

目的通过光学相干断层成像(OCT)初步评价冠状动脉内支架术后即刻支架周围组织结构特点。方法随机入选15例冠状动脉粥样硬化性心脏病(冠心病)行支架置入术患者,在患者置入支架后用OCT成像系统评价术后即刻支架释放情况及支架贴壁情况。结果15例患者共置入36枚支架,OCT检查得到满意图像并显示有14例患者冠状动脉内支架各部分充分释放,支架与血管壁贴合良好,无斑块组织向血管腔内突入,支架连接处贴合好;有1例患者支架部分节段释放不充分,支架与血管壁贴合不良,支架连接处贴合欠佳。结论OCT检查可充分评价支架释放及血管壁贴合和支架连接处管壁贴合情况,是检查支架术后支架周围组织结构的一种重要方法。

preliminary analysis of peri-stent structure after percutaneous coronary stenting at once by optical coherence tomography

Objective Preliminary evaluate of peri-stent structure after percutaneous coronary stenting at once by optical coherence tomography（OCT）.Methods 15 patients with coronary artery disease,were implanted 36 stents.Optical coherence tomography was performed after percutaneous coronary stent implant with OCT system （Lightlab,USA） to assess the stent expansion,stent and vessel apposition,coronary plaque tissue prolapse from stent struts,stent and stent apposition.Results Qualitative OCT images were acquired after percutaneous coronary stenting in 15 patients.Complete expansion were found in 14 patients,not found coronary plaque tissue prolapse from stent struts.One segmental stent and vessel complete apposition,One segmental stent and stent complete apposition,One segmental incomplete expansion,One segmental stent and vessel incomplete apposition,One segmental stent and stent incomplete apposition.Conclusion Because of OCT is high resolution,can complete evaluate stent expansion,stent and vessel apposition,tissue prolapse from stent struts and stent and stent apposition.OCT is an effective method to detect peri-stent structure after percutaneous coronary stenting.
