IVUS measurements include external elastic membrane area(EEMA), minimal lumen area(MLA), and area stenosis(AS), style of endomembrane tear and dissection.
以IVUS分析外弹力膜内横截面积（EEMA）、最小管腔横截面积（MLA）、管腔面积狭窄率（AS）以及内膜撕裂类型和夹层形成。
Conclusion IVUS is the effective ways to access the ISR, the larger plaque area, neointimal area but smaller minimal lumen area were seen in patients with ISR.
结论 血管内超声是评价支架内再狭窄的有效的手段， 支架内再狭窄患者有更大的斑块面积和内膜增生面积，而最小管腔面积变小。
