variable presentation in pregnancy is

Introduction. Cephalic presentation is the most physiologic and frequent fetal presentation and is associated with the highest rate of successful vaginal delivery as well as with the lowest frequency of complications 1.Studies on the frequency of breech presentation by gestational age (GA) were published more than 20 years ago 2, 3, and it has been known that the prevalence of breech ...

Toward the end of pregnancy, the fetus moves into position for delivery. Normally, the presentation is vertex (head first), and the position is occiput anterior (facing toward the pregnant person's spine) and with the face and body angled to one side and the neck flexed. Variations in fetal presentations include face, brow, breech, and shoulder.

Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. ... Like the transverse lie, this position is more common earlier in pregnancy, and it's likely your provider will intervene if your baby is still in the oblique lie ...

breech presentation: fetal rump presenting towards the internal cervical os, this has three main types. frank breech presentation (50-70% of all breech presentation): hips flexed, knees extended (pike position) complete breech presentation (5-10%): hips flexed, knees flexed (cannonball position) footling presentation or incomplete (10-30%): one ...

Nausea and vomiting of pregnancy is also common in around 80% of pregnant patients but with variable severity and presentation [43, 44]. It can present as early as the 2 nd week and last up until the 2 nd trimester, and in some cases until 37 weeks' gestation or full term [45-47]. This is important to keep in mind as clinicians need to ...

From 22 to 36 weeks of gestation, the prevalence of cephalic presentation increased from 47% (45-50%) to 94% (91-96%), before and after which times plateaus were noted. Spontaneous change from breech to cephalic is unlikely to occur after 36 weeks of gestation.

This concept has been most fully developed for pre-eclampsia, a complex disorder with variable presentation and outcome, but the origin is to be found in early pregnancy failure of spiral artery remodeling. In normal pregnancies, at about 8-17 weeks, trophoblasts invade the arteries, replacing the smooth muscle and endothelium.

In early pregnancy fetuses have a variable lie within the uterus. As the pregnancy approaches the latter part of the third trimester, the majority of singleton pregnancies have a longitudinal lie and the fetus enters the pelvis with a cephalic presentation. Transverse lie, compound presentation, face presentation, and brow presentation together ...

The fetus undergoes a series of changes in position, attitude, and presentation during labor. This process is essential for the accomplishment of a vaginal delivery. The presence of a fetal malpresentation or an abnormality of the maternal pelvis can significantly impede the likelihood of a vaginal delivery. The contractile aspect of the uterus ...

Little is known about the transition patterns of fetal presentation during pregnancy [Citation 1, Citation 7, Citation 8]. Some reports have revealed that non-cephalic ratio is relatively high until ... Categorical variables were analyzed using the Chi-squared (if all the values were larger than 10) or Fisher's exact tests. In the analysis to ...

The relative incidence of differing fetopelvic relations varies with diagnostic and clinical approaches to care. Among longitudinal lies, about 1 in 25 fetuses are not cephalic but breech at the onset of labor. 1 Of the differing lies a fetus may assume, about 1 in 100 is transverse or oblique, also referred to as nonaxial. As pregnancy proceeds to term, most fetuses assume a longitudinal lie ...

Toward the end of pregnancy, the fetus moves into position for delivery. Normally, the presentation is vertex (head first), and the position is occiput anterior (facing toward the pregnant patient's spine) with the face and body angled to one side and the neck flexed. Abnormal presentations include face, brow, breech, and shoulder.

Abnormal Fetal Lie. If the fetal lie is abnormal, an external cephalic version (ECV) can be attempted - ideally between 36 and 38 weeks gestation. ECV is the manipulation of the fetus to a cephalic presentation through the maternal abdomen. It has an approximate success rate of 50% in primiparous women and 60% in multiparous women.

Compound presentation refers to the finding of part of a fetal extremity alongside the presenting part, usually an arm or hand alongside the fetal head. The most common associations are with prematurity and multiple pregnancy, usually the second twin that only engages in the pelvis following delivery of the first.

Adverse neonatal outcomes result from a complex interplay of intrapartum events, antepartum complications, placental function or dysfunction, and uterine perfusion.[1] Electronic fetal monitoring is widely utilized intrapartum to assess fetal status, to prevent adverse neonatal outcomes such as fetal asphyxia or cerebral palsy. Unfortunately, there is high intraobserver and interobserver ...

Summary: The fetal lie, presentation, and position was recorded serially from the 16th week of gestation until delivery in 100 pregnant women. The incidence of these characteristics varied with gestation and parity, with stabilization of fetal lie occurring at the 22nd week in nulliparous patients, and at the 30th week in parous patients; the frequency of longitudinal lie rose from 63% at 16 ...

While the concept of a viable and nonviable pregnancy is relatively easy to grasp, it is governed by strict definitions. From a clinical perspective, a viable pregnancy is one in which the baby can be born and have a reasonable chance of survival. By contrast, a nonviable pregnancy is one in which the fetus or baby has no chance of being born ...

The nature of the presentation of denial of pregnancy is variable and often depends on the underlying problems. A risk score is almost impossible to construct, meaning that it is extremely difficult to predict women who may suffer from this condition. ... Due to its variable presentation, denial of pregnancy is a difficult condition to diagnose.
