目的探讨法洛四联症的超声心动图诊断。方法选取临床2011年3月~2014年3月收治的法洛四联症胎儿21例超声心动图诊断资料进行分析。结果主动脉前壁与室间隔连续中断,室间隔位于主动脉前后壁间,主动脉增宽,右心室增大,右心室前壁增厚,流出道狭窄。比积均显著提高。结论超声心动图可以准确判断室间隔缺损的大小及位置、右室流出道及肺动脉狭窄程度,对于外科手术治疗尤为重要。
Objective To investigate the diagnosis of tetralogy of Fallot by echocardiography. Methods Twenty-one cases of tetralogy of -fertility diagnosed by echocardiography from March 2011 to March 2014 were analyzed. Results The aortic anterior wall and interventricular septum were interrupted continuously. The interventricular septum was located between the anterior and posterior walls of the aorta. The aorta was widened, the right ventricle was enlarged, the anterior wall of the right ventricle was thickened and the outflow tract was narrowed. Than the product were significantly improved. Conclusion Echocardiography can accurately determine the size and location of ventricular septal defect, right ventricular outflow tract and the degree of pulmonary stenosis, for surgical treatment is particularly important.
