目的探讨彩色多普勒血流显像(CDFI)在心肌梗死伴室间隔穿孔诊断中的临床应用价值。方法回顾性分析2005年1月至2009年11月中国医科大学附属第一医院收治的7例经数字减影血管造影技术(DSA)证实室间隔穿孔的患者,将造影结果与术前的CDFI检查结果进行对照分析,观查与总结CDFI的特征及表现。结果经DSA证实7例室间隔穿孔患者,穿孔部位均位于心尖部,7例患者CDFI均正确诊断,准确度为100%。结论CDFI对心肌梗死伴室间隔穿孔的诊断准确率高,可以作为早期诊断室间隔穿孔的手段。
Objective To investigate the clinical value of color Doppler flow imaging (CDFI) in the diagnosis of myocardial infarction with ventricular septal perforation. Methods A retrospective analysis was performed on seven patients with ventricular septal perforation confirmed by digital subtraction angiography (DSA) from January 2005 to November 2009 in the First Affiliated Hospital of China Medical University. The imaging results were compared with preoperative CDFI Results of the control analysis, review and summarize the characteristics and performance of CDFI. Results In DSA-confirmed 7 patients with ventricular septal perforation, the perforation sites were all located in the apical part. CDFI was correctly diagnosed in 7 patients and the accuracy was 100%. Conclusion CDFI has a high diagnostic accuracy for myocardial infarction with ventricular septal perforation, which can be used as an early diagnosis of ventricular septal perforation.
