The 80% of MoDi pregnancies without TTTS still have high rates of birth weight discordance, fetal growth restriction, prematurity and resultant cesarean section deliveries. [1] One twin may also fail to develop a proper heart and become dependent on the pumping activity of the other twin's heart, resulting in twin reversed arterial perfusion. [2]
A low birth weight can be caused either by a preterm birth (low gestational age at birth) or the infant being small for gestational age (slow prenatal growth rate), or a combination of both. [10] Small for gestational age is defined as below the 10th percentile for gestational age and sex. [11]
Parity, or "para", indicates the number of births (including live births and stillbirths) where pregnancies reached viable gestational age. A multiple pregnancy (e.g., twins, triplets, etc.) carried to viable gestational age is still counted as 1. [3] Abortus is the number of pregnancies that were lost prior to viable gestational age for any ...
For example, if there is a gestational age based on the beginning of the last menstrual period of 9.0 weeks, and a first-trimester obstetric ultrasonography gives an estimated gestational age of 10.0 weeks (with a 2 SD variability of ±8% of the estimate, thereby giving a variability of ±0.8 weeks), the difference of 1.0 weeks between the ...
[1] [2] [3] Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute measurement, regardless of gestational age. [4] Typically the threshold for diagnosing macrosomia is a body weight between 4,000 and 4,500 grams (8 lb 13 oz and 9 lb 15 oz), or more, measured at birth, but there are difficulties reaching a ...
As of 2022, the world record for the lowest gestational age newborn to survive is held by Curtis Zy-Keith Means, who was born on 5 July 2020 in the United States, at 21 weeks and 1 day gestational age, weighing 420 grams. [5] A preterm birth, also known as premature birth, is defined as babies born alive before 37 weeks of pregnancy are ...
Identical twins Brooklyn and Bailey McKnight have had a large social media presence since they were 13 — and the 22-year-old influencers are only gaining in popularity.
Abdominal ultrasonography of monoamniotic twins at a gestational age of 15 weeks. There is no sign of any membrane between the fetuses. A coronal plane is shown of the twin at left, and a sagittal plane of parts of the upper thorax and head is shown of the twin at right.
