Özet
AimThe aim of this study was to document the clinical and cytogenetic results of a large series of amniocentesis (AS) cases from Turkey. Material and MethodsSecond-trimester amniocentesis cases performed in Suleymaniye Maternity Hospital for Research and Training between January 2007 and December 2011 were included. ResultsDuring this period, 6124 AS were performed. Indications were increased risk in maternal serum screening (MSS) (56%), advanced maternal age (29%) and pathologic ultrasound finding (11.5%). Most frequent MSS abnormality was abnormal triple test result (58%). Overall culture success rate was 98.8%. Chromosomal abnormality was detected in 215 (3.6%) of the 6052 cytogenetic results (74.9% numerical, 25.1% structural). Most frequent numerical chromosomal abnormality was trisomy 21 (61.9%). Clinically insignificant polymorphisms were the most frequent structural changes (n=571). Most frequent polymorphism was increase in heterochromatin region in the 1st chromosome (n=158). Advanced maternal age had a positive predictive value of 5.2%. Among the MSS tests, the combined test had the highest positive predictive value (5.2%). ConclusionsIn our study, abnormal MSS (and among these, abnormal triple test result) was the most frequent indication for amniocentesis. Our overall culture success rate was 98.8%. Frequency of major chromosomal abnormality was 3.2% and trisomy 21 was the most frequent abnormality.
