Cordocentesis in the diagnosis of intrauterine starvation
American Journal of Obstetrics and Gynecology, 1989Glycine and valine were measured in umbilical venous blood obtained by cordocentesis from 28 small-for-gestational-age fetuses. The values were compared with those from 62 appropriate-for-gestational-age fetuses. The ratio of glycine to valine was higher in the small-for-gestational-age fetuses and correlated significantly with the degree of fetal ...

Cordocentesis for rapid karyotyping
American Journal of Obstetrics and Gynecology, 1990Pure fetal blood was obtained by cordocentesis in 101 fetuses of 96 patients at 15 to 38 weeks' gestation. Rapid karyotype was obtained within 2 to 4 days by fetal lymphocyte culture. Chromosomal abnormality was detected in 12 (11.9%) fetuses.

The development of cordocentesis has permitted for the first time safe and direct evaluation of our second patient. The information garnered from the specimens obtained by cordocentesis will lay the groundwork for the development of primary-care fetal medicine--fetology.

Fetal bradycardia following cordocentesis
Prenatal Diagnosis, 1997Several clinical investigations on the course and outcome of pregnancies following cordocentesis have mentioned the occurrence of fetal bradycardia at the time of umbilical cord puncture. The prognostic impact of this common complication has remained controversial.

Cordocentesis in the investigation of fetal erythropoiesis
American Journal of Obstetrics and Gynecology, 1989Fetal blood hemoglobin concentration and erythrocyte, reticulocyte, and erythroblast counts were determined in umbilical cord samples obtained from 194 pregnancies at 17 to 40 weeks' gestation. The fetuses sampled were undergoing prenatal diagnosis and were subsequently found not to be affected by the condition investigated.

Efficacy and safety of cordocentesis for prenatal diagnosis
International Journal of Gynecology and Obstetrics, 2006To assess the efficacy and safety of diagnostic cordocentesis.Between January 1991 and May 2004, 2,010 cordocentesis were performed in the outpatient setting in 2,010 women with singleton pregnancies. A fixed needle guide and a 22-gauge percutaneous needle were used and no more than 2 attempts were allowed at 1 visit.

Diagnostic Use of Cordocentesis in Twin Pregnancy
Fetal Diagnosis and Therapy, 2009We performed percutaneous umbilical blood sampling, under ultrasound guidance, in both twins of 11 twin pregnancies in whom twin-to-twin transfusion syndrome was suspected. Chorionicity and the presence of placental vascular anastomoses were assessed postnatally.

Current Opinion in Obstetrics and Gynecology, 1994
Cordocentesis has pioneered perinatal medicine in the last 10 years with the ability to obtain genetic information, to diagnose and to treat erythrocyte and platelet alloimmunization, to discover the presence of perinatal infections, and to determine the acid-base status of the fetus.

What Can Be Learned From Cordocentesis?
Clinics in Laboratory Medicine, 1992Cordocentesis is a well-accepted procedure that is widely practiced by experienced perinatologists. Its facile and safe access to the fetal circulation has broadened the spectrum of congenital disorders diagnosed prenatally. Some fetal disease states can now be identified and treated earlier, directly, more quickly, and more effectively than before ...
