25 de ene. de 2017 · Triploidy is a rare lethal numeric chromosomal aberation caused by the presence of an extra haploid chromosome set. It occurs in about 17% of all spontaneous abortion during first trimester and occurring in up to 3% of recognized human conceptuses.

23 de feb. de 2023 · Spontaneous RSA abortions caused by fetal triploidy accounted for about 8% of miscarriages, second only to RSA caused by aneuploidy [12,13]. Until now, there has been no rapid and accurate technique to detect triploidy in clinical practice; however, our new method will solve this problem perfectly.

5 de mar. de 2024 · A triploidy pregnancy results in spontaneous abortion, or severe birth defects and growth restriction that are incompatible with life. Diagnosis is confirmed with either chorionic villus sampling or amniocentesis. Treatment is aimed at palliative care for the newborn and extensive counseling and support for the family members.
1 de ene. de 2018 · It is the third most common cytogenetic abnormality identified at spontaneous abortion, preceded by monosomy and trisomy. Most triploidies abort spontaneously during the first trimester. If the pregnancy does not abort, the fetus and/or placenta are usually structurally abnormal. Syndactyly and ventriculomegaly are common malformations.
24 de sept. de 2003 · Triploidy is the most frequent chromosome aberration in first trimester spontaneous abortions. In contrast to aneuploidies due to nondisjunction, increased maternal age is not a risk...

11 de feb. de 2020 · A triploid conceptus contains three copies of each chromosome resulting in a total of 69 chromosomes. Triploidy is a common chromosomal anomaly associated with 8%‐10% of spontaneous abortions. 1 In triploid pregnancies, the extra haploid set of chromosomes can be either maternally or paternally derived.
We present important clinical aspects of triploid pregnancies and indicate unresolved issues demanding further studies. Keywords: diandric triploidy; digynic triploidy; gestational trophoblastic neoplasia; maternal triploidy; partial hydatidiform mole; paternal triploidy.
