摘要
目的:探讨胎儿动脉导管狭窄及早闭的超声心动图诊断价值及预后。方法:观察并总结1例胎儿动脉导管早闭及6例胎儿动脉导管狭窄的超声心动图表现及预后。结果:胎儿动脉导管狭窄及早闭主要表现为动脉导管变细或截断、动脉导管收缩期及舒张期血流增快、三尖瓣反流、右心扩大、主肺动脉内径增宽、肺动脉压力增高等。胎儿动脉导管狭窄或早闭若能得到有效处理,一般预后良好。结论:胎儿超声心动图在胎儿动脉导管狭窄及早闭的诊断中有重要作用。
Objective： To discuss the value of echocardiography in diagnosis of premature closure and constriction of fetal ductus arteriosus, and to observe the prognosis. Methods： Analyzing the echocardiography features in 1 case of premature closure of fetal ductus arteriosus and 6 cases of constriction of fetal ductus arteriosus, observing the prognosis of all 7 cases. Results： The main echocardiography features of premature closure and constriction of fetal ductus arteriosus were truncation or narrowing of the lumen, accelerated systolic and diastolic blood flow in ductus arteriosus, tricuspid regurgitation, dilation of right heart, broadening of main pulmonary artery and increased pulmonary artery pressure. The prognosis was favorable if the treatment was appropriate. Conclusion： Echocardiography plays an important role in diagnosis of premature closure and constriction of fetal ductus arteriosus.
