经食管实时三维超声技术在人工二尖瓣瓣周漏诊断及治疗中的应用价值

Applications of real-time three-dimensional transesophageal ultrasound technology in the diagnosis and treatment of artificial mitral paravalvular leak

目的:研究经食管实时三维超声(RT3D-TEE)在人工二尖瓣瓣周漏(PVL)的诊断及应用价值。方法:选择我院2011年5月至2013年5月收治人工二尖瓣PVL病患51例,在其内、外科术前、后,均给予经食管二维超声(2D-TEE)及RT3D-TEE检查,分析两种检查结果准确度。结果:应用RT3D-TEE技术检查病患PVL漏口位置诊断结果准确性显著高于应用2D-TEE技术,测得PVL漏口大小数据显著大于应用2D-TEE技术所测(均P<0.05)。结论:RT3D-TEE对病患PVL漏口位置诊断更加准确、可靠,可辅助医生术前诊断,并为术中监护提供实时超声信息,监测病患术后疗效情况。

Objective To assess the application values of real-time three-dimensional transesophageal ultrasound （RT3D-TEE） technology in the diagnosis and treatment of artificial mitral paravalvular leak （PVL）. Methods Fifty-one cases of artificial mitral PVL patients were received two-dimensional transesophageal ultrasound （2D-TEE） and RT3D-TEE examination before and after surgery. Accuracy analysis was performed between the two kinds of test. Results The diagnostic accuracy of RT3D-TEE technique in patients with PVL drain port positionwas significantly higher than that of 2D-TEE technology, and the data of PVL drain port size by RT3D- TEE technique is significantly larger than that of 2D-TEE technique （P 〈 0.05, respectively）. Conclusion The PVL laboratory diagnosis based on RT3D-TEE is accurate and reliable, and RT3D-TEE can assist doctom to diagnose before operation, and can provide real-time ultrasound information from intraoperative monitoring, and monitor the postoperative efficacy of patients.
