摘要
目的 :应用血管内超声研究目标病变钙化情况。方法 :113例患者接受冠状动脉造影及血管内超声检查。血管内超声检查及测量 :强回声伴声影判断为钙化灶 ,若目标病变 2处以上钙化 ,钙化弧相加。根据钙化在血管内超声图像上血管壁内分布的位置可将钙化部位分成下列几类 :①浅表性钙化。②深层钙化。③混合性钙化 ,冠状动脉造影 :依据荧光透视下钙化的特征性表现发现目标病变钙化。结果 :血管内超声发现 6 5例(5 7.5 % )目标病变钙化 ,平均钙化弧为 (112± 10 6 )°。其中浅表性钙化 35例 (5 3.8% ) ,深层钙化 11例 (16 .9% ) ,混合性钙化 19例 (2 9.2 % )。并发现 5 9例 (2 9% )参考血管病变钙化 ,平均钙化弧为 (6 8± 6 5 )°(与目标病变相比P <0 .0 1) ,其中浅表性钙化 4 1例 (6 9.5 % ) ,深层钙化 6例 (10 .2 % ) ,混合性钙化 12例 (2 0 .3% )。而荧光透视仅发现 2 0例 (18% )目标病变钙化 (与血管内超声相比P <0 .0 1)。结论 :血管内超声可以准确地识别冠状动脉内斑块钙化程度、分布 ,并据此选择合适的治疗手段。
Objective:Using intravascular ultrasound (IVUS), we aimed to study the plaque composition and their effects on interventional treatment.Method: One hundred and thirteen patients underwent coronary artery angiography (CAG) and IVUS examinations. The target lesion location from angiography was left anterior descending artery (LAD) in 68 patients, left circumflex artery in 13 and right coronary artery in 32. Result: IVUS detected 65 ( 57.5 %) target lesions calcification, which was only superficial in 35 ( 53.8 %), only deep in 11( 16.9 %), and mixed in 19 ( 29.2 %). The mean calcium are of target lesions was ( 112±106)°. Compared with target lesions, 59 (29%) reference lesions had calcification which showed only superficial in 41 ( 69.5 %), only deep in 6 ( 10.2 %), and mixed in 12 ( 20.3 %). The mean calcium arc of reference lesions measured (68±65)°(P< 0.01 ). However, fluoroscopy only found 20 (18%) target lesions calcification (P< 0.01 versus IVUS).Conclusion: The IVUS can accurately identify the existance and the degree of calcification and help to choose appropriate treatment.
