Placenta abruptio

Cesarean section

1. The uterus is exposed through the abdominal wall, and an incision is made in the uterine covering. 2. The muscles of the uterus are separated, producing a hole for the delivery of the infant. 3. The infant is delivered through the opening in the uterine wall, after which, the uterus is stitched closed.

Ultrasound in pregnancy

The ultrasound has become a standard procedure used during pregnancy. It can demonstrate fetal growth and can detect increasing numbers of conditions including meningomyelocele, congenital heart disease, kidney abnormalities, hydrocephalus, anencephaly, club feet, and other deformities. Ultrasound does not produce ionizing radiation and is considered a very safe procedure for both the mother and the fetus.

Anatomy of a normal placenta

The placenta provides the fetus with oxygen and nutrients and takes away waste such as carbon dioxide via the umbilical cord.

Placenta

In the placenta, nutrients, wastes, and gases are exchanged between the mothers blood and the babys blood.

Placenta

The placenta grows during pregnancy and stays connected to the wall of the uterus where it provides the fetus with nourishment. The placenta also secretes hormones that help regulate and maintain the pregnancy.

Ultrasound, normal placenta - Braxton Hicks

This is a normal ultrasound performed at 17 weeks gestation. It shows the placenta during a normal (Braxton Hicks) contraction. Throughout the pregnancy, the uterus periodically contracts to facilitate better blood flow through the placenta and the fetus. In this ultrasound, the placenta can be seen as the mound-shaped object in the middle of the screen. At the bottom of the image, the mother's vertebra can be seen as a round object. When the uterus is not contracting, the placenta would appear much flatter.

Ultrasound, normal fetus - arms and legs

This is a normal fetal ultrasound performed at 19 weeks gestation. This is the type of spilt-screen display you might see during an ultrasound, or if the technician prints a copy of the ultrasound for you. This ultrasound shows both the left arm (seen in the left side of the display), and the lower extremities (seen in the right side of the display). The white areas of the arm or legs is developing bone.

Ultrasound, normal relaxed placenta

This is a normal fetal ultrasound performed at 19 weeks gestation. This ultrasound shows two interesting features. In the foreground, to the left and middle of the screen, you can see the placenta, following the curve of the uterus. In the background on the right, where the cross hair is pointing, you can see the face with all the facial features visible.

Ultrasound, color - normal umbilical cord

This is a normal color Doppler ultrasound of the umbilical cord performed at 30 weeks gestation. The cord is the colored area in the middle of the screen, with the different blood vessels represented by different colors. There are normally three vessels in the cord, two arteries and one vein. The umbilical cord is connected to the placenta, located in the middle left of the image.

Placenta

The placenta supplies the fetus with the blood supply and nutrients necessary for survival.
