| 摘 要： | 目的:探讨血管内超声测量法与目测法两种方法在判定冠状动脉狭窄时的应用,以确定目测法在支架置入术前存在低估现象,而在术后对残余狭窄评判存在低估现象。方法:对拟行冠脉内支架的34位冠心病患者的46处病变,在经皮冠状动脉球囊成形术前和支架置入后即刻进行血管内超声图像采集,同时记录目测冠脉造影结果,加以对比分析。结果:血管内超声测量与目测法在冠脉内支架置入前后的直径狭窄率测量方面存在统计学差异。结论:目测法存在术前高估狭窄和术后低估残余狭窄的现象,血管内超声可以使冠脉支架置入术得到优化。

| Abstract: | Objective:To evaluate the effect of stent implanation by intravascular ultrasound(IVUS) and visualization,and determine whether the visualization underestimated before operation or underestimated residual stenosis after operation.Methods:The 46 coronary stents of 34 patients were studied.IVUS were used before percutaneous transluminal coronary angioplasty(PTCA) and after intracoronary stenting,and the visualized results were recorded and compared.Results:IVUS and visualization methods showed statistically differences in measuring the rate of coronary stenosis before and after intracoronary stent implantation.Conclusion: The visualized method present overestimating stenosis before operation and underestimating stenosis after operation.IVUS can assess the intracoronary stent implantation accurately. |
