Objective: To determine whether iliac wing angle measurements in second trimester fetuses is a useful sonographic marker for the detection of trisomy 18. Methods: During the period between September 1998 and September 2001, 406 fetal iliac angle measurements were performed in women in the second trimester of their pregnancies. Of the 406 fetuses 376 (92.61%) fetuses had adequate images of the pelvic bones for satisfactory measurements of the iliac wing angle, thirty control fetuses (7.39%), in which the measurement was unworkable, were excluded from the investigation. Of these 376 fetuses, 333 (88.56%) were healthy and 43 (11.43%) had chromosome aberrations: trisomy 21 (n=25), trisomy 18 (n=10), trisomy 13 (n=5), or other chromosomal aberrations (n=3). The iliac angle measurements in fetuses with trisomy 18 were compared with iliac angle measurement in fetuses with normal karyotypes. Results: The mean iliac wing angle in the fetuses with trisomy 18 was 79,35° (the mean iliac wing angle in the healthy fetuses was 70.09°). Conclusion: The sonographic measurement of the fetal iliac angle can not be used as a marker for trisomy 18. We have shown that fetuses with trisomy 18, on average, have iliac angles only a few degrees larger than healthy fetuses.
