[Clinical application of abdominal cordocentesis under ultrasound guidance].

OBJECTIVE

To evaluate the safety and success rate of abdominal cordocentesis using a PTC needle under ultrasound guidance.

METHODS

Cordocentesis was performed under ultrasound guidance in 103 pregnant women with indications of prenatal diagnosis.

RESULTS

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.

CONCLUSION

Abdominal cordocentesis under ultrasound guidance is a safe and reliable approach for prenatal diagnosis.
