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。

IVUS measurements include external elastic membrane area(EEMA), minimal lumen area(MLA), and area stenosis(AS), style of endomembrane tear and dissection.

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。

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.
