ABSTRACT
Because the diagnosis of ruptured splenic artery aneurysm in pregnancy is seldom made before operation, maternal and fetal mortality continues to be high. The authors describe the case of a 22-year-old woman who had a ruptured splenic artery aneurysm at 32 weeks' gestation. The attending obstetrician considered this condition in the differential diagnosis and it was confirmed by ultrasonography, leading to a successful outcome.

Although post-term pregnancy is associated with an increased incidence of fetal distress, oligohydramnios, fetal macrosomia, fetal dysmaturity, and perinatal mortality, as many as 80% of post-term fetuses appear completely normal. The authors of this article discuss the three sub-groups of post-term pregnancies, and deal with the diagnosis and antepartum and intrapartum management of the condition. Recommendations and a protocol for management are provided.
ABSTRACT
The management of premature rupture of the amniotic membranes before 37 weeks gestation remains controversial. The authors of this article outline the risks involved for the fetus, define the various terms related, and discuss the antepartum and intrapartum management of such an event and offer a protocol that they have developed.
ABSTRACT
Nonimmune hydrops was induced in six fetal lambs at 120 days' gestation by right atrial pacing at 300 beats/min. Biochemical, hemodynamic, and Doppler parameters were observed and monitored by real-time ultrasound during the creation (18 to 42 hours) and resolution of hydrops. The significant changes seen were hypoproteinemia (34.3 to 29.0 mg/100 ml), venous hypertension (24.6 to 31.3 mm Hg), decreases in thoracic aorta flow, and decreases in systolic/diastolic ratios in the aorta and umbilical artery. These changes were reversed with the discontinuation of pacing and the resolution of fetal hydrops.

Normograms for ultrasound-measured fetal chest and heart circumferences were constructed from 83 normal pregnancies of 24 to 39 weeks' duration. Of six cases at risk for pulmonary hypoplasia, all of whom ultimately proved to have the condition, four fell below the fifth percentile for chest circumferences. Both cases in which the chest circumference was within the normal range had pleural effusions.
