What is annular placenta?

What is annular placenta?

Annular placenta is a placenta in the form of a band encircling the interior of the uterus. It is very rare but commonly related to placental vessel abnormalities, frequently causing antenatal and postnatal hemorrhage and operative delivery (2).

How is BPD determined on ultrasound?

BPD (biparietal diameter), the diameter of your baby’s head. HC (head circumference), the length going around your baby’s head. CRL (crown-rump length), the length from the top of the head to your baby’s bottom, measurement taken in the first trimester.

What are the three types of abnormal Placentation?

Abnormal Placentation: Placenta Previa, Vasa Previa, and Placenta Accreta.

How do you read a Level 2 ultrasound report?

During a level 2 ultrasound, baby will be measured from crown to rump, around the middle, around the head — and that’s just for starters. The four chambers of the heart will be viewed, as well as the kidneys, bladder, stomach, brain, spine and genitalia.

What is a discoid placenta?

discoid placenta. A placenta in which part of the chorion remains smooth, while the other part interacts with the endometrium to form the placenta. The maternal blood cells are in direct contact with the fetal chorion.

What is normal bpd in ultrasound?

Your doctor is looking for the BPD measurement, as well as the other measurements, to be within what is considered normal range. The biparietal diameter measurement increases from roughly 2.4 centimeters at 13 weeks to approximately 9.5 centimeters when a fetus is at term.

What is Vasa Previa?

Vasa previa occurs when unprotected fetal blood vessels run through the amniotic membranes and traverse the cervix. Complications include fetal hemorrhage, exsanguination, or death. Diagnosis by ultrasound.

What is a Level 3 ultrasound?

Level III Obstetric Ultrasound (advanced anatomical detail): In this ultrasound the existence of all fetal organs is checked, and abnormalities in the anatomic structure is dismissed. Besides, amniotic fluid, placenta, and uterus are evaluated.

What are the diagnostic tests for hydatidiform mole?

A pregnancy test is done. If women have a hydatidiform mole, results are positive, but no fetal movement and no fetal heartbeat are detected. Blood tests to measure the level of human chorionic gonadotropin (hCG-a hormone normally produced early in pregnancy) are done.

What does hydatidiform mole mean?

A hydatidiform mole is growth of an abnormal fertilized egg or an overgrowth of tissue from the placenta. Women appear to be pregnant, but the uterus enlarges much more rapidly than in a normal pregnancy. Most women have severe nausea and vomiting, vaginal bleeding, and very high blood pressure.

Does hydatidiform mole result from genetic abnormalities?

A complete molar pregnancy is caused when the egg has no genetic information, and is fertilized by one or two sperms. Due to the lack of genetic information from the mother’s side, the fertilized egg develops a placenta that looks like a cluster of grapes without an accompanying fetus.

What is nonhydatidiform mole?

Hydatidiform mole. Molar pregnancy is an abnormal form of pregnancy in which a non-viable fertilized egg implants in the uterus and converts a normal pregnancy into an abnormal one. A molar pregnancy is a gestational trophoblastic disease that grows into a mass in the uterus that has swollen chorionic villi.
