Aim: To evaluate the developmental pattern of fetal hand movements and facial activity and expression during the second and third trimester of pregnancy by four-dimensional ultrasound (4D-US).
Subjects And Methods: A total of 25 fetuses in uncomplicated pregnancies were analyzed; 15 fetuses at 13 to 16 weeks and 10 fetuses at 30 to 33 weeks of gestation were studied with abdominal 4D-US. After standard assessment in two dimensional (2D) real-time B mode, a 4D mode was switched on.
Aim: To assess the accurate establishment of chorionicity, perinatal complications, and outcome of monochorionic twin pregnancies managed in a tertiary referral center in Croatia and compare the findings with data published for other countries.
Methods: The retrospective analysis included data on a total of 24 monochorionic twin pregnancies delivered at the Department between January 1998 and May 2002. The data retrieved from the maternity ward birth register included the ultrasound establishment of chorionicity, demographic data, complications of the pregnancy (presence of twin-to-twin-transfusion syndrome, intrauterine growth restriction, and threatened or actual preterm labor rate), and pregnancy outcome.
