摘要
目的:评价血管内超声(IVUS)对小血管病变介入治疗的临床意义。方法回顾性分析2010年10月~2013年2月于我院接受介入治疗的单支小血管(≤2.5mm)病变患者共237例,其中,IVUS指导下介入治疗的患者105例(Ⅰ组),冠状动脉造影(CAG)指导下介入治疗的患者132例(Ⅱ组)。分析2组患者基线资料、病变特点、介入治疗及随访期间心脏不良事件和再狭窄情况。结果2组患者介入治疗均成功,Ⅰ组和Ⅱ组置入支架直径[(2.50±0.40)mmvs(2.34±0.37)mm]、支架长度[(28.75±7.77)mmvs(35.78±10.45)mm]、支架高压后扩张(91.4%vs55.3%)和支架内再狭窄(1.9%vs7.6%)比较,差异有统计学意义(P=0.002,P=0.000,P=0.000,P=0.042);2组串联支架、CAG随访比较差异无统计学意义(P>0.05)。2组患者住院及随访1、3和6个月期间,均无主要不良心脏事件发生。结论对于小血管病变的介入治疗,IVUS具有较好的指导作用。
Objective To assess the clinical significance of intravascular ultrasonography (IVUS)-guided intervention therapy for small vessel lesions .Methords Two hundred and thirty-seven patients who underwent intervention therapy for single vessel (≤2 .5 mm) lesions in our hospital from October 2010 to February 2013 were divided into IVUS-guided intervention therapy group (n=105)and coronary ateriography-guided group (n=132) .Their baseline parameters ,lesion features ,main adverse cardiac events (MACE) and restenosis during follow-up were analyzed . Results Intervention therapy for the two groups was successful .The diameter ,length ,dilation and restenosis of stents were significantly different between the two groups ( P= 0 .002 ,P=0.000 ,P= 0.000 ,P= 0 .042) .However ,no significant difference was found in the incidence of series stent and MACE during follow-up (P〉0 .05) .Conclusion IVUS plays an important role in intervention therapy for small vessel lesions .
