Sonographic screening for trisomy 13 at 11 to 13(+6) weeks of gestation.
OBJECTIVE The purpose of this study was to examine the sonographic features of trisomy 13 at 11 to 13(+6) weeks of gestation. STUDY DESIGN This was a retrospective study that examined the features of trisomy 13 at the ultrasound scan at 11 to 13(+6) weeks of gestation, which in our center is performed for the measurement of crown-rump length, nuchal translucency thickness, and fetal heart rat...
متن کاملDilated fourth ventricle in fetuses with trisomy 18, trisomy 13 and triploidy at 11-13 weeks' gestation.
OBJECTIVE To determine if in fetuses with aneuploidies the diameter of the fourth cerebral ventricle at 11-13 weeks' gestation is different from euploid fetuses. METHODS The fourth ventricle at 11-13 weeks' gestation was assessed in 62 cases of trisomy 21, 32 of trisomy 18, 10 of trisomy 13, and 12 of triploidy and compared to 410 normal euploid fetuses. Transvaginal sonography was carried ou...

OBJECTIVE To measure changes in the posterior fossa of first-trimester fetuses with trisomy 18, trisomy 13 and triploidy. METHODS Brain stem (BS) diameter and BS to occipital bone (BSOB) diameter were measured in images of the midsagittal view of the face at 11(+0) to 13(+6) weeks from 45 trisomy 18, 21 trisomy 13 and 15 triploid fetuses and compared with values in 162 euploid fetuses.

متن کاملMaternal thyroid function at 11-13 weeks of gestation.
OBJECTIVE To establish normal ranges of maternal serum thyroid-stimulating hormone (TSH), free thyroxine (FT4) and free triiodothyronine (FT3) at 11-13 weeks of gestation. METHODS Maternal serum concentrations of FT3, FT4, TSH, anti-thyroperoxidase (anti-TPO) and anti-thyroglobulin (anti-Tg) antibodies were measured at 11-13 weeks. Normal ranges were constructed from the data of singleton pre...
متن کاملMaternal serum placental protein 13 at 11-13 weeks of gestation in preeclampsia.
OBJECTIVE To examine the potential value of maternal serum concentration of placental protein 13 (PP13) at 11-13 weeks' gestation in screening for preeclampsia (PE). METHODS Serum PP13, PAPP-A and uterine artery pulsatility index (PI) were determined in a case-control study of 208 cases that developed PE including 48 that required delivery before 34 weeks (early-PE) and 416 unaffected control...
