Intraoperative ultrasound imaging was employed for qualitative and quantitative studies during cardiovascular operations in 36 patients. A 7.5M Hz high frequency ultrasound scanner was used to image. The ultrasound probe was sterilized by gas and placed directly on the heart by the hand of surgeon. On the clinical application, 10 cases of patients with coronary artery disease were scanned. Left main trunk and proximal portion of other three branches were visualized and pathological lesions were demonstrated clearly. Four cases of myocardial bridging were observed. Intramyocardial coronary arteries were easily detected and supraarterial myotomy was performed safely. Four cases of valvular disease were examined. We could evaluate valvular anatomy and physiologic aspects of valvular disease and 15 cases of aortic root disease were examined intraoperatively. In aortic root dissection, the size and site of the true and false lumens were clearly demonstrated in all patients. In conclusion intraoperative ultra-sound imaging is a versatile technique with quantitative and qualitative studies of cardiovascular surgery during operation and the perioperative period.
对36例患者在心血管手术期间采用术中超声成像进行定性和定量研究。使用一台7.5兆赫的高频超声扫描仪进行成像。超声探头经气体消毒后由外科医生亲手直接置于心脏上。在临床应用中，对10例冠心病患者进行了扫描。左主干及其他三个分支的近端得以显影，病理病变清晰可见。观察到4例心肌桥。心肌内冠状动脉易于检测，并且安全地进行了动脉上肌切开术。对4例瓣膜病患者进行了检查。我们能够评估瓣膜解剖结构以及瓣膜病的生理方面情况，术中还对15例主动脉根部疾病患者进行了检查。在主动脉根部夹层中，所有患者的真腔和假腔的大小及位置均清晰显示。总之，术中超声成像是一种多功能技术，可在手术及围手术期对心血管手术进行定性和定量研究。
