“…The incidence of placental mosaicism concurs with other reports. In a recent study, mosaicism was observed in 1.1 per cent of 1000 CVS cases (Young et al, 1991). In a large U.S. multicentre study comprising a total of 11 473 cases, the incidence of placental mosaicism was 0.8 per cent (Ledbetter et al, 1992).…”

Transabdominal chorionic villus sampling and amniocentesis for prenatal diagnosis: 5 years' experience at a University Centre

et al. 1994

The fetal loss rates and fetal congenital birth defects in 821 transabdominal (TA) chorionic villus sampling (CVS) and 771 amniocentesis (AC) cases were evaluated from a 5-year period (1987-1991) at the University Central Hospital of Turku. The parents were given the option of choosing between the two sampling procedures. CVS was performed, in most cases, at 11 weeks of gestation; and AC, at 15 weeks. The rate of total post-procedure loss was 6.7 per cent in the CVS group and 4.4 per cent in the AC group (p = 0.08). The rate of spontaneous abortions was 1.9 per cent in the CVS group and 1.0 per cent in the AC group (p = 0.10). The number of birth defects was low in both study groups. No limb reduction cases were observed. Mosaicism was noted in 14 CVS cases and in five AC cases. We conclude that TA-CVS is a safe and practical alternative to AC in prenatal fetal karyotyping.

“…[6] In 1990's comparisons were made between amniocentesis and chorionic villus sampling and no significant difference could be found. [7] After study of Nicolaides et al with routine use of nuchal translucency combined with beta-hCG and PAPP-A at 11th week -13th week 6th day, chorionic villus sampling performed during this time has begun the most early prenatal invasive test. [8] Besides widespread use of prenatal invasive tests, research about diagnostic noninvasive tests has continued due to difficulties in learning invasive methods, their risks and complications.…”

Objective: Invasive prenatal tests have still been important and indispensable. We aimed to share the indications, results and complications of our amniocentesis and chorion villus sampling cases from Gaziantep Gynecology and Maternity Hospital.Methods: Data from 253 amniocentesis and 15 chorion villus sampling procedures between 2010-1011 have been analyzed retrospectively.Results: Genetic abnormality was detected in 6.8% of amniocentesis (n=17) and 26.6% of chorion villus sampling cases (n=4). 3.2% of the chromosomal abnormalities were numerical (n=8) and the most common of it was trizomy 21 (2.8%, n=7). Total fetal loss was 0.7% (n=2). Conclusion:The similarity of genetic abnormality and complication rates with the literature is encouraging for the educated and experienced staff to perform invasive procedures in the hospitals except university and education hospitals.

“…Second-trimester amniocentesis has been used for more than 30 years for prenatal diagnosis of genetic disorders 5,6 . With the introduction of ultrasound technology into clinical practice in the mid to late seventies the procedure became easier and less traumatic to the fetus and the mother, but it still has some complications, the major one being fetal loss.…”

“…With the introduction of ultrasound technology into clinical practice in the mid to late seventies the procedure became easier and less traumatic to the fetus and the mother, but it still has some complications, the major one being fetal loss. Different centers report rates varying between 0.2% and 3.7% (with a follow-up duration of 3 -4 weeks) [5][6][7][8][9][10][11][12][13] .…”
