摘要 目的 探讨光学相干断层成像(OCT)与血管内超声(IVUS)在经皮冠状动脉介入(PCI)术中的应用效果。方法 102例不稳定型心绞痛患者拟行PCI,于PCI术前、术中及术后依次行IVUS和OCT检测,获取两组图像并比较两种方法检测冠状动脉斑块成分特征、病变管径相关参数及并发症。结果 术前OCT脂质斑块、纤维斑块的检出率均明显低于IVUS,混合斑块、斑块侵蚀及斑块破裂的检出率均显著高于IVUS(均P<0.05);支架植入后,OCT支架贴壁不良、支架边缘夹层、支架内残余血栓及支架内斑块脱垂检出率均明显高于IVUS(均P<0.05);术后12个月,OCT晚期支架贴壁不良、支架边缘夹层及支架内斑块/血栓脱垂检出率均明显高于IVUS(均P<0.05)。结论 OCT和IVUS均可用于指导PCI术,OCT对术前斑块性质(斑块侵蚀、斑块破裂、红、白血栓)及术后并发症(支架贴壁不良、支架内残余血栓、支架边缘夹层及支架内组织脱垂)的识别优于IVUS,OCT能准确测量内衬纤维帽厚度,识别出薄帽纤维粥样斑块(TCFA),而IVUS能检测斑块负荷及血管重构指数。二者联用可取长补短,为未来的发展趋势。
