Thirteen-week cornual ectopic pregnancy.

30 Aug 2009 We present the unusual case of a 13-week cornual ectopic pregnancy with fetal movement. The patient presented with a protuberant abdomen, intoxicated with cocaine and alcohol, and in hemodynamic compromise. Bedside emergency ultrasonography led to ... Read more...

Fetal volume and crown-rump length from 7 to 10 weeks of gestational age in singletons and twins.

19 Apr 2009 OBJECTIVE(S): We intend to verify if fetal volume and crown-rump length were different between singletons and twins in pregnancies aged from 7 to 10 weeks and to evaluate if fetal volume is more accurate to determine the gestational age than ... Read more...

The assessment of the gestational sac diameter, crown-rump length, progesterone and fetal heart rate measurements at the 10th gestational week to predict the spontaneous abortion risk.

30 Mar 2009 AIM: The assessment of the first trimester ultrasonographic and progesterone measurements to predict spontaneous abortion risk. METHODS: Ninety-nine women at the 10th week of pregnancy were included in this prospective study. Their ages, ... Read more...

Technical information about 'Crown-Rump Length'

Definition: In utero measurement corresponding to the sitting height (crown to rump) of the fetus. Length is considered a more accurate criterion of the age of the fetus than is the weight. The average crown-rump length of the fetus at term is 36 cm. (From Williams Obstetrics, 18th ed, p91)
