Bentall术后冠状动脉吻合口漏并假性动脉瘤形成的超声诊断价值

目的 探讨二维及彩色多普勒超声在Bentall术后冠状动脉吻合口漏并假性动脉瘤形成诊断中的应用价值。方法 对本院16例Bentall术后临床诊断为冠脉动脉吻合口漏并假性动脉瘤形成患者的二维超声及彩色多普勒超声征像进行总结，并与主动脉造影结果进行对比分析。结果 16例患者人工血管周围二维超声均可探及搏动性无回声区，冠状动脉吻合口处彩色多普勒可显示异常血流信号，其中左侧9例，右侧7例。所有超声结果均与主动脉造影结果一致。结论 超声心动图可以及时、准确、无创诊断Bentall术后冠脉吻合口漏及并发的假性动脉瘤，可作为临床随访检查的首选方法。

Diagnostic value of echocardiography in coronary anastomotic leakage and pseudoaneurysm formation after Bentall operation

Objective: Analysis of two-dimensional and color Doppler echocardiography of coronary anastomotic leakage and pseudoaneurysm after Bentall''s operation, and to evaluate the diagnostic value of echocardiography. Methods Sixteen patients were diagnosed with coronary anastomotic leakage and pseudoaneurysm after Bentall surgery in our hospital were enrolled, and their two-dimensional and color Doppler echocardiography findings were analyzed and summarized. The results of echocardiographic diagnosis and aortic angiography were compared. Results Two-dimensional echocardiography can detect the pulsating anechoic zone around the artificial blood vessels of 16 patients, and color Doppler can show abnormal blood flow signals at the anastomotic stoma of the coronary artery. There were 9 patients occurred in the left anastomosis and 7 patients occurred in the right side among them. All the ultrasound results were coincident with aortic angiography results. Conclusion Echocardiography can detect Bentall ''s postoperative coronary anastomotic leakage and concurrent pseudoaneurysm in a timely, accurate and non-invasive manner, which can be used as the first choice for clinical follow-up examination.
