All Rights Reserved. The development of both the fetus and the placenta is seriously affected. Image 7 shows the fetus, note small omphalocele. Placenta showed high growth rate. We did not see any other fetal abnormalities except of the small omphalocele. A year-old woman is in her 20th week of gestation. Seven months later, the same woman underwent a spontaneous abortion of a week fetus in her subsequent pregnancy. Cytogenetic examination of the placenta confirmed our suspicion of the placental triploidy.

Ziadie, M.D.. Triploid placenta with normal fetal karyotype The relationship of placental pathology to an adverse pregnancy outcome has been well Images 3,4: Images show thick placenta and the fetus pressed to the corner of the uterine cavity.

Spontaneous abortion occurred within five days, at 18 weeks of gestation. The rate of the placental growth is unpredictable, but spontaneous abortion occurs usually before 20 weeks of gestation due to a fetal compression by placental tissue that fills the entire uterine cavity.
Karyotype analysis of both amniotic fluid and placental tissue of the first fetus showed a 69, XXX triploid karyotype.

ticlike picture without true sepsis. The other. Placental pathologic conditions include abnormalities of placental size, cord. the zonal architecture of the uterus on T2-weighted images, which can be. triploidy, and very rarely in placental mesenchymal dysplasia (PMD).
Four weeks prior she noted bright red vaginal bleeding and was placed on bed rest.
Placental pathology of triploidy.
Karyotype is 69 XXY, 69 XXX or 69XYY 3 possible mechanisms: Dispermia: fertilization of haploid egg by two sperms most common Diandria: fertilization of haploid egg by diploid sperm Digynia: fertilization of diploid egg by haploid sperm The extra chromosomal set can either be of a paternal dispermia, diandria or maternal digynia origin. The relationship of placental pathology to an adverse pregnancy outcome has been well recognized.
She complained of a vaginal bleeding which started around 15 weeks of gestation. Triploidy is one of the most frequent chromosomal aberrations in humans and the most frequent chromosomal abnormality in the first trimester abortions. We did not see any other fetal abnormalities except of the small omphalocele.
