PURPOSE
To compare angiographic and intravascular ultrasound (IVUS) data before and after balloon angioplasty (PTA) of the femoropopliteal artery.
METHODS
Qualitative and quantitative analyses were performed on corresponding angiographic and IVUS levels obtained from 135 patients.
RESULTS
IVUS detected more lesions, calcified lesions, and vascular damage than angiography. Sensitivity of angiography was good for the presence of a lesion (84%), moderate for eccentric lesions (53%) and for vascular damage (52%), and poor for calcified lesions (30%). The increase in angiographic diameter stenosis was associated with a decrease in lumen area and increase in percentage area stenosis on IVUS.
CONCLUSIONS
Angiography is less sensitive than IVUS for detecting lesion eccentricity, calcified lesions, and vascular damage. Presence of a lesion and amount of plaque were underestimated angiographically. Only before PTA was good agreement found between angiographic diameter stenosis and lumen size on IVUS.
目的
比较股腘动脉球囊血管成形术（PTA）前后的血管造影和血管内超声（IVUS）数据。
方法
对135例患者相应的血管造影和IVUS水平进行定性和定量分析。
结果
与血管造影相比，IVUS检测到更多的病变、钙化病变和血管损伤。血管造影对病变存在的敏感性良好（84%），对偏心病变（53%）和血管损伤（52%）的敏感性中等，对钙化病变的敏感性较差（30%）。血管造影直径狭窄的增加与IVUS上管腔面积的减少和面积狭窄百分比的增加相关。
结论
血管造影在检测病变偏心性、钙化病变和血管损伤方面不如IVUS敏感。血管造影对病变的存在和斑块数量存在低估。仅在PTA前，血管造影直径狭窄与IVUS上的管腔大小之间存在良好的一致性。
