摘要
目的:探讨血管内超声(IVU S)对不稳定心绞痛(UA)患者介入治疗的价值。方法:UA患者20例,其中男12例,女8例,平均年龄(57.8±3.2)岁,冠状动脉造影(CAG)未见明显狭窄,通过IVU S检查,对斑块的性质、形态、部位、血管的狭窄程度、血管重构情况进行分析,再选择介入治疗与否。结果:IVU S检查共发现位于前降支(LAD)回旋支(LCX)及右冠状动脉(RCA)的斑块22处,其中纤维斑块6例,软斑块12例,4例钙化斑块。8例施行了支架植入的患者的临床症状明显好转。结论:CAG未见明显狭窄的UA患者有必要进行IVU S检查,因可明确冠状动脉斑块性质,为是否需要介入治疗提供重要依据。
Objective：To approach the application of intravascular unltrasound on interventional therapy in patients with unstable angina pectoris. Methods：There were 20 patients with UA which included 12 males and 8 females, the average age of them was 57.8± 3.2. All of them with no significant coronary artery stenosis. Through IVUS exami nation,to analysis the nature,shape,location of the plaque ,the degree of vascular stenosis and the situation of vascular remodeling,then decide whether or not to choose interventional treatment. Results：IVUS examination was found 22 plaque at anterior descending artery （LAD） ,left circumflex coronary artery （LCX） and right coronary artery （RCA） ,in which 6 cases were fibrous plaque, 12 were soft plaque,4 were calcified plaque. The clinical symptoms of the eight cases of patients with stent implantation were marked improved. Conclusions ：It is very essential for patients with UA with no significant stenosis in CAG to take the IVUS examination. Because it can identify the nature of coronary artery plaque ,to provide an important basis for interventional therapy.
