摘要 目的探讨胎儿心室内强回声灶与胎儿心脏结构异常的相关性。方法对642例超声筛查发现心室内强回声灶胎儿检查结果进行分析。结果 642例心室内强回声灶胎儿其中伴发有心脏结构异常、不伴有心脏结构异常者分别占7.94%、92.06%;不伴有心脏结构异常胎儿左心室单发强回声灶、右心室单发强回声灶、左心室多发强回声灶、右心室多发强回声灶、双室强回声灶分布构成比分别为96.10%、1.52%、1.02%、0.68%、0.68%,伴有心脏结构异常胎儿以上部位强回声灶分布构成比分别为31.36%、15.69%、17.65%、17.65%、17.65%,比较差异具有统计学意义(P<0.01);伴心脏结构异常胎儿分别为室间隔缺损、单心室、单心房、左心发育不良、法洛氏四联症、右心室双出口、肺动脉瓣狭窄,所占构成比分别为15.69%、5.88%、3.92%、1.96%、43.14%、27.45%、1.96%。结论胎儿心室内强回声灶与胎儿心脏结构异常之间关系密切,存在一定相关性,强回声灶为右心室单发、左心室或右心室多发、双室强回声灶时胎儿心脏结构异常发生几率较高,在超声筛查时如存在以上部位强回声灶要进一步检查胎儿是否存在心脏结构异常。
