摘　　要：目的评价光学相干断层成像(OCT)技术在不稳定性心绞痛患者长病变经皮冠状动脉介入治疗(PCI)中的应用效果。方法选择22例不稳定性心绞痛患者,其中男性12例,女性10例,在OCT指导下对存在弥漫性长病变的罪犯血管行PCI术。结果 22例患者,共22处弥漫性长病变,平均长度(45±3)mm,共植入支架47枚,支架植入后冠状动脉造影显示支架均完全覆盖病变、膨胀完全、贴壁良好,未发现残余狭窄、边缘夹层及支架内血栓。OCT检查发现14例患者支架植入术后存在贴壁不良和(或)膨胀不全,10例患者使用1次非顺应性球囊扩张后明显改善,4例患者使用2次非顺应性球囊扩张后明显改善。结论 OCT检查安全、可靠,重复性好,能够优化PCI策略及手术过程。Objective To evaluate the application effect of optical coherence tomography （OCT） in percultaneous coronary intervention （PCI） of unstable angina with length lesions. Methods Twenty-two patients with unstable angina were selected, including 12 males and 10 females. Patients who had diffuse long lesion of culprit vessels were examined with OCT and then underwent PCI. Results Twenty-two patients had diffuse long lesions with an average length of （45_＋3） mm; and 47 stents were implanted. Coronary angiography showed that the stents covered the lesions completely, swelled completely and adhered well. No residual stenosis, edge dissection and stent thrombosis were found. OCT revealed stent malappositon and （or） underexpansion in 14 patients after stent implantation, 10 patients improved after noncompliance balloon dilatation once, and 4 patients improved after noncompliance balloon dilatation twice. Conclusion OCT is a safe, reliable and reproducible method, and it can optimize PCI strategy and operations.
