目的探讨产前超声诊断胎儿动脉导管狭窄及缺如的价值及意义。方法利用超声诊断仪对3例动脉导管狭窄及4例动脉导管缺如进行回顾性分析。结果 3例动脉导管狭窄病例,1例右室压达88 mm Hg,选择剖腹产。另外2例右室压<60 mm Hg,随访至出生。4例动脉导管缺如胎儿合并严重先天性心脏病,均选择引产,尸检结果与超声诊断基本相符。结论产前超声对于诊断胎儿动脉导管狭窄及缺如有重要临床价值。
Objective To investigate the value and significance of prenatal ultrasound in diagnosis of stenosis and absence of fetal arterial catheter. Methods Three cases of patent ductus arteriosus stenosis and four cases of patent ductus arteriosus were retrospectively analyzed by ultrasonic diagnostic apparatus. Results 3 cases of patent ductus arteriosus and 1 case of right ventricular pressure of 88 mm Hg, choose caesarean section. The other 2 patients had right ventricular pressure <60 mm Hg and were followed up until they were born. In 4 cases with patent ductus arteriosus and fetus with severe congenital heart disease, all induced abortion was selected. The autopsy results were basically consistent with those of ultrasound diagnosis. Conclusion Prenatal ultrasound has important clinical value in diagnosis of stenosis and absence of fetal arterial catheter.
