Objective. In this study, we applied the fluorescent in situ hybridization (FISH) technique and compared the common numerical abnormalities with chromosomes 13, 16, 18, 21, X, and Y in spontaneous to artificial abortion. This would cover about 75% of the common aneuploidy in spontaneous abortion. Methods. Placentas were taken from 59 patients with a first trimester spontaneous abortion and 61 patients who underwent an elective first trimester pregnancy termination. The range of growth was from 5 to 12 gestational weeks. Placentas were processed according to direct chorionic villi preparation. Direct dual color FISH was performed according to Vysis protocol with the probes for the following chromosomes: 13, 16, 18, 21, X, and Y. Results. The aneuploidy rate in spontaneous abortion was 55.9% and in artificial abortion 8.2%. There was a significant difference between the two groups in the aneuploidy rate ( P = 6 × 10 −9 ). Conclusion. FISH is a rapid, efficient, and relatively inexpensive tool in detecting a...
