To evaluate the safety and success rate of abdominal cordocentesis using a PTC needle under ultrasound guidance.
Cordocentesis was performed under ultrasound guidance in 103 pregnant women with indications of prenatal diagnosis.
The success rate of cordocentesis was 98.1% (101/103). Abnormal chromosome karyotype was detected in 5, intrauterine cytomegalovirus infection in 2 and alpha-thalassemia major (Hb Barts disease) in 3 cases. Severe complications such as miscarriage, fetal death, placental abruption or intrauterine infection were not found after the operation.
Abdominal cordocentesis under ultrasound guidance is a safe and reliable approach for prenatal diagnosis.

对103例有产前诊断指征的孕妇在超声引导下进行脐静脉穿刺术。
脐静脉穿刺术的成功率为98.1%（101/103）。检测出5例染色体核型异常，2例宫内巨细胞病毒感染，3例重型α地中海贫血（血红蛋白巴特氏病）。术后未发现流产、胎儿死亡、胎盘早剥或宫内感染等严重并发症。
超声引导下经腹脐静脉穿刺术是一种安全可靠的产前诊断方法。
