超声检查肺门部大血管横切面预测胎儿心脏锥干系统疾病的价值

Value of hilar great arteries transverse view in prenatal diagnosis of conotruncal defects

目的探讨超声检查肺门部大血管横切面在预测胎儿心脏锥干系统疾病中的价值。方法 28例经我院产前超声心动图诊断为锥干系统疾病的胎儿,分析其肺门部大血管横切面的超声表现。结果 28例锥干系统疾病胎儿(完全型大动脉转位5例,矫正型大动脉转位2例,法洛氏四联症7例,法洛氏四联症合并肺动脉瓣缺如1例,永存动脉干5例,右室双出口8例),肺门部大血管横切面声像图表现异常24例,包括血管数目、血管排列、位置关系及血管内径异常。结论肺门部大血管横切面的应用对于胎儿锥干系统疾病的产前诊断和预后评估有重要意义。

Objective To evaluate the value of hilar great arteries transverse view in diagnosing fetal conotruncal defects. Methods Sonagrams of hilar great arteries transverse view in 28 fetuses with conotruncal defects were analyzed.Results Among 28 fetuses with conotruncal defects including 5 cases of complete transposition of great arteries, 2 cases of corrected transposition of great arteries, 7 cases of tetralogy of Fallot, 1 case of tetralogy of Fallot combing with absent pulmonary valve, 5 cases of persistent truncus arteriosus and 8 cases of double-outlet right ventricle, 24 of them showed an abnormal hilar great arteries transverse view that included abnormal vessel number,abnormal arrangement and abnormal vessel size.Conclution Hilar great arteries transverse view plays an important role in the prenatal diagnosis and prognostic evaluation of fetal conotruncal defects.
