| 摘 要： | 目的 通过血管内超声显像(IVUS)研究,了解冠状动脉造影(CAG),提示冠状动脉中度狭窄病变的性质及狭窄程度,为临床治疗方案的选择提供决策依据.方法 对经CAG发现冠状动脉存在中度狭窄的36例患者47处病变进行IVUS检查,观察病变斑块性质、特征和血管最大狭窄程度,并对CAG和IVUS两种检查结果 进行比较.结果 CAG不能显示管腔形态及斑块特点,CAG发现偏心性狭窄13处,向心性狭窄34处,病变最窄处血管直径狭窄率为(45.24±12.1)%;IVUS检测发现偏心性斑块38处,向心性斑块9处,不稳定斑块29处.IVUS所测病变最窄处直径狭窄率为(56.37±11.2)%(CAG,P<0.05),血管面积狭窄率为(79.51±15.5)%,行冠脉内支架植入31处.结论 中度狭窄病变多为不稳定易损斑块,IVUS可准确地判定冠状动脉的病变性质和狭窄程度,更好地指导临床确定治疗策略.

| Abstract: | Objective To investigate the characteristics and lesion of angiographic intermediate coronary stenosis using intravascular ultrasound(IVUS).Methods Forty-seven coronary artery segments with intermediate stenosis found by coronary artery angiography(CAG) in 36 patients were measured by IVUS.We analyzed the characteristics of the plaques by IVUS.The stenostic morphology and the severity of intermediate stenoses in two techniques were compared.Results The lumen morphology and plaque characteristics could not b... |
