【摘要】 目的:探讨超声对快速二期大动脉调转术治疗完全性大动脉转位(D—TGA)的临床应用价值。方法:总结分析2005年8月—2011年6月15例施行快速二期大动脉调转术的D—TGA患儿超声心动图表现,比较术前、术中、术后左心室的变化及手术结果,总结分析一期肺动脉环缩术后行二期手术的最佳时机。结果:15例患者一期术后,评估解剖左室,显示室间隔凸向右室面,左心室呈圆形,提示实行二期手术时机已到。二期术后一个月内死亡4例,手术成功率约73.3%。术后3个月随访,1例死于重症肺炎,其余10例主动脉、肺动脉吻合口血流通畅。结论:超声心动图对快速二期大动脉调转术治疗D—TGA的评估手术时机、术中监测以及术后随访均发挥着十分重要的作用。

Clinical Study of Echocardiography in Rapid Two—stage Arterial Switch Operation for Patients with Transposition of Great Arteries/CHU Wen.//Medical Innovation of China,2012,9(29):030—031

【Abstract】 Objective:To evaluate the value of echocardiography in rapid two—stage arterial switch operation for patients with transposition of great arteries(D—TGA).Method:15 patients of D—TGA underwent rapid two—stage arterial switch operation from August 2005 to June 2011.Trace above 15 cases during every phrases of surgery with echocardiography.Result:For 15 cases of rapid two—stage ASO,we could find a left to right bulging of the interventricular when the left ventricule had a circular shape and left ventricule diastolic dimension(LVDD) increased after pulmonary artery banding.Above reminded to two—stage AS0.4 patients died among 1 month after rapid two—stage arterial switch operation.3 months later after operation,1 patient died for lung inflammation.Conclusion:Echocardiography plays an important role in studying ASO during every phrases of surgery.

完全性大动脉转位(D—transposition of the great arteries,D—TGA)是新生儿期最易发生心力衰竭、死亡率最高的紫绀型先心病。大动脉调转术(arterial switch operation,ASO)治疗D—TGA要求患儿在出生后3周内。若患儿诊治时年龄稍大,左心室心肌退化,直接行ASO成功率较低[1],可行快速二期大动脉调转术。本研究总结分析施行快速二期大动脉调转术的患儿超声心动图表现,探讨超声对该手术的术中检测及术后疗效评估的应用价值。

1 资料与方法

1.1 一般资料 2005年8月—2011年6月在郑州大学第一附属医院和洛阳市中心医院手术的共15例D—TGA患者,男9例,女6例;年龄52 d~2岁,中位年龄0.8岁;体质量4.7~15.0 kg。15例D—TGA中10例合并房间隔缺损,8例合并动脉导管未闭,10例合并小的室间隔缺损(3~6 mm)。15例患者均未合并肺动脉狭窄。……
