What is a vertex presentation?

In vertex presentations the head of the fetus most commonly faces to the right and slightly to the rear. This position is said to be the most usual one because the fetus is thus best accommodated to the shape of the uterus. In breech presentation the buttocks or the legs are the first to pass through the pelvis.

Is normal delivery possible in vertex presentation?

Is vertex presentation normal? Yes, the vertex position of the baby is the most appropriate and favourable position to achieve normal delivery. “About 95% of babies are in vertex presentation (head down) at 36 weeks, while 3-4% may lie in a ‘breech position,” says Dr. Anita.

What does vertex mean on ultrasound?

Which presentation is best for normal delivery?

Ideally for labor, the baby is positioned head-down, facing your back, with the chin tucked to its chest and the back of the head ready to enter the pelvis. This is called cephalic presentation. Most babies settle into this position with the 32nd and 36th week of pregnancy.

Can baby turn back to breech at 38 weeks?

It is fairly common for a baby to be in a breech position before 35 to 36 weeks gestation, but most gradually turn to the head-down position before the last month.

What is the difference between cephalic and vertex presentation?

Most babies move into the head down position by the third trimester. Cephalic presentation is further broken down by the position of the head; in the vast majority of cephalic deliveries, the crown or top of the head (called the vertex), enters the birth canal first and is the first part of the baby to be delivered.

Can a baby go from vertex to breech?

All cases of change from vertex- into breech presentation were seen until the 35th week of pregnancy, not later, whereby the cases of change from breech- into vertex presentation happend until the 36th week of pregnancy (except one “late” change in the 39th week in a multipara), in the primiparae until the 36th week.

Is vertex the same as cephalic?

Cephalic presentation is further broken down by the position of the head; in the vast majority of cephalic deliveries, the crown or top of the head (called the vertex), enters the birth canal first and is the first part of the baby to be delivered.

In a compound presentation, however, there are multiple presenting parts. Most commonly, this means that the baby’s head and an arm come out first at the same time.

Which representation does not Favour vaginal delivery?
