冠心病慢性完全闭塞是冠心病中最为严重的病变类型,在介入治疗中开通难度大,术后并发症多。光学相干断层成像技术具有分辨率高,组织相关性良好等特点。在临床应用中,应用光学相干断层成像技术能够在介入治疗前对慢性完全闭塞血管进行评估,术中指导导丝通过病变,术后评估边缘夹层、支架贴壁不良等并发症,为支架植入提供更多的临床信息。现就光学相关断层成像在冠心病慢性完全闭塞病变中的应用进展进行简要介绍。
Chronic total occlusion is the most severe type of coronary heart disease,featuring many difficulties in performing interventional techniques and postoperative complications.Optical coherence tomography is characterized by high resolution ratio and good correlation.The application of optical coherence tomography in clinical settings can evaluate chronic total occlusion of blood vessels before interventional therapy,guide guidewires getting through lesions during operation,and evaluate complications such as bad limbic dissection and incomplete stent apposition after operation,providing more clinical information for stent apposition.Now a brief introduction was presented on the application of optical coherence tomography to interventional treatment of chronic total occlusion of coronary heart disease (CHD).
