All symptoms normally resolve within three weeks, and may only last days. [1] Permanent deficits are seen in a minority of patients, ranging from under 10% to 20% in various studies. [1] Less than 5% of patients experience progressive vasoconstriction, which can lead to stroke, progressive cerebral edema, or even death. [1]
Cerebroplacental ratio is a tool used in obstetric ultrasound to predict adverse pregnancy outcome. [1] It is measured by dividing the pulsatility index of the middle cerebral artery of the foetus by the pulsatility index of the umbilical artery of the foetus. A cerebroplacental ratio lower than 1-1.1 in uncomplicated pregnancies is indicative ...
American law requires that certain drugs and biological products must be labelled very specifically. Title 21, Part 201.57 (9)(i) of the Code of Federal Regulations lists specific requirements regarding the labeling of drugs with respect to their effects on pregnant populations, including a definition of a "pregnancy category".
According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.

Spalding's sign is a sign used in obstetrics. [1] It is named for Alfred Baker Spalding. [2] [3]It is an indicator of fetal death. [4] When fetal death has occurred loss of alignment and overriding of the bones of cranial vault occur due to shrinkage of cerebrum, [5] abdominal sonar examination may reveal an overriding of the fetal cranial bones.

In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

This diagnosis is generally found in routine fetal anomaly scans at 18–22 weeks gestation. It is one of the more common abnormal brain findings on prenatal ultrasound, occurring in around 1–2 per 1,000 pregnancies. [4] In many cases of mild ventriculomegaly, however, there is resolution of ventriculomegaly during the pregnancy.
