Electron beam CT (EBCT) has been devised to improve the imaging of the heart and the great vessels. Therefore, this method is expected to facilitate the imaging workup of patients referred for cardiothoracic surgery. We set out to review the most important surgical issues that can be addressed with this method.
From June, 1997 until July, 1998, more than 300 patients were referred from cardiothoracic surgery. In a retrospective analysis, diagnostic results were reviewed and compared with surgical findings and the clinical course.
Aortocoronary bypass graft occlusions were detected with a sensitivity of 100% and a specificity of 95%. Calcifications of the aorta, pericardium and intracardiac tumors were surgically confirmed in all instances. There was a significant association of the degree of coronary artery calcification and the progression of cardiac allograft vasculopathy in 50 heart transplant recipients. In EBCT of the aorta, a high degree of diagnostic confidence was found for aortic dissection, aortic wall hematoma or aortic perforation.
We conclude that EBCT represents an important diagnostic tool both for surgical planning and postoperative surveillance in cardiothoracic surgery.
电子束CT（EBCT）已被设计用于改善心脏和大血管的成像。因此，这种方法有望促进心胸外科转诊患者的成像检查。我们着手回顾用这种方法可以解决的最重要的外科问题。
从1997年6月至1998年7月，超过300名患者由心胸外科转诊而来。在一项回顾性分析中，对诊断结果进行了审查，并与手术结果和临床病程进行了比较。
检测到主动脉冠状动脉搭桥移植闭塞的灵敏度为100%，特异性为95%。所有病例中，主动脉、心包和心内肿瘤的钙化均经手术证实。在50名心脏移植受者中，冠状动脉钙化程度与心脏移植血管病变进展之间存在显著关联。在主动脉的EBCT检查中，对主动脉夹层、主动脉壁血肿或主动脉穿孔有高度的诊断信心。
我们得出结论，EBCT是心胸外科手术规划和术后监测的重要诊断工具。
