Abstract
Using a variety of molecular techniques, it has been established that loss of pregnancy occurs in one to two thirds of all fertilized embryosin the first trimester. In about 50% of the cases, chromosomal abnormalities are the cause of early spontaneous abortion. Several histological characteristicsof the placenta, such as presence of villous stromal cavitations, fetal erythro-cytes, umbilical cord, fetal tissue,etc. are suggested as predictive factors for aneuploidy.Two hundred and thirty one cases were analyzed in this prospective study, 50 cases were control artificial abortionsand 181 cases were early spontaneous abor-tionsanalyzed in the period from May 2012 to De-cember 2014. Standard histopathological analysis and molecular techniques based on polymerase chain reaction were usedto analyze the samples.Usingmolecular techniques, aneuploidy was detected in 53.1% of the samples. The most frequently detected aneuploidy was trisomy 16, followed by trisomy 22, 21, 14 and 18. The molecular analysis also enabled dis-tinctionof maternal and paternal origin of the alleles.In the histopathological sample analysis, binary logis-tic regression analysis indicated the presence of trophob-lasticproliferation (p=0.008) and the absence of fetal red bloodcells (p=0.001) as independent significant fac-tors in the prediction of aneuploidy in early sponta-neous abortion.In conclusion, our results show that clinically relevant andaccurate diagnosis of early spontaneous abortionwhich candetermine its causecan only be achieved bya controlled process of selection of the material,histo-pathological and molecular analysis, followed bya necessary correlation of these results.
