While angiography remains the standard evaluation method for the visualisation of coronary artery anatomy and morphology, the angiographic findings in patients referred for surgical treatment of coronary artery disease (CAD) often do not totally answer questions related to surgical management. We therefore explored a high-frequency ultrasonic technique that allows the surgeon to localize coronary artery lesions not demonstrated angiographically, such as the distribution of coronary artery calcification in myocardial vessels buried in fat or obscured by epicardial scarring frequently observed in patients who had previously been operated upon. Coronary arteries of 81 patients were investigated intraoperatively. Stenotic arteriosclerotic or fibrotic lesions of the arterial wall could be easily seen. This technique provides additional information to preoperative angiograms, especially in locating major coronary arteries that lie intramyocardially, or those deeply buried in fat. Intraoperative coronary artery dilatation procedures could be followed and the effects determined by measuring pre- and postoperative diameters.
虽然血管造影术仍然是可视化冠状动脉解剖结构和形态的标准评估方法，但因冠状动脉疾病（CAD）接受手术治疗的患者的血管造影结果往往不能完全回答与手术管理相关的问题。因此，我们探索了一种高频超声技术，该技术可让外科医生定位血管造影未显示的冠状动脉病变，例如在曾接受过手术的患者中经常观察到的、埋于脂肪中或被心外膜瘢痕遮挡的心肌血管中的冠状动脉钙化分布。术中对81例患者的冠状动脉进行了研究。动脉壁的狭窄性动脉硬化或纤维化病变很容易被观察到。该技术为术前血管造影提供了额外信息，特别是在定位位于心肌内或深埋于脂肪中的主要冠状动脉时。术中可以跟踪冠状动脉扩张程序，并通过测量术前和术后直径来确定效果。
