Comparison of ultrasonographic findings in spontaneous abortions with normal and abnormal karyotypes.
To determine whether ultrasonographic findings can predict the karyotype of spontaneous abortions, 137 pregnancies (54 spontaneous, 83 assisted ovulatory cycles) that subsequently aborted and had chromosome analysis performed on the products of conception were studied ultrasonographically. Transvaginal ultrasound was performed using an Acuson 128XP/10 with 7.5 MHz probe. The numbers of empty ge...
متن کاملChromosomal Analysis of Couples with Repeated Spontaneous Abortions in Northeastern Iran
Background Cytogenetic study of reproductive wastage is an important aspect in determining the genetic background of early embryogenesis. Approximately 15 to 20% of all pregnancies in humans are terminated as recurrent spontaneous abortions (RSAs). The aim of this study was to detect chromosome abnormalities in couples with RSAs and to compare our results with those reported previously. Materia...
متن کاملBalanced Chromosomal Rearrangement in Recurrent Spontaneous Abortions: A Case Report
One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16 6) (p12 q26) and 46, X...
متن کاملP-243: Prenatal Diagnosis Using Array CGH: Case Presentation
Background: Karyotype analysis has been the standard and reliable procedure for prenatal cytogenetic diagnosis since the 1970s. However, the major limitation remains requirement for cell culture, resulting in a delay of as much as 14 days to get the test results.CGH array technology has proven to be useful in detecting causative genomic imbalances or genetic mutations in as many as 15% of child...
متن کاملHeterochromatic polymorphism in spontaneous abortions.
Since the advent of C-banding as a routine diagnostic procedure, the significance of heterochromatic polymorphism has been questioned. Some workers have considered variations in heterochromatin in chromosomes 1 and 9 to be associated with fetal wastage, recurrent abortions, and abnormal phenotypes. Over a 15-month period, this laboratory made a study of the diagnostic significance of heterochro...
