Q

Allantois

A

a tubular extension of the endoderm of the yolk sac

that extends with the allantoic vessels into the connecting

stalk of theembryo. In human embryos, allantoic vessels

become the umbilical vessels and the chorionic villi.

Q

yolk sac

A

circular structure within the gestational sac seen on ultrasound between 4-10 weeks of gestational age; supplies nutrition, facilitates waste removal and is the origin of early hematopoietic stem cells in the embryo; it lies between the chorion and the amnion

25
basal plate
maternal side of the placenta
26
functions and activities of the placenta
respiration nutrition excretion protection storage hormonal production
27
Respiration
Transfer of oxygen from maternal blood across the placental membrane into fetal blood is by diffusion. The placenta acts as fetal lungs
28
Nutrition
Water, inorganic slats, carbohydrates, fats, proteins, and vitamins pass from maternal blood through the placental membrane into fetal blood
29
Excretion
Waste products cross membrane from fetal blood and enter maternal blood. Excreted by mother’s kidneys
30
Protection
Some microorganisms cross the placental border
31
Storage
carbohydrates, proteins, calcium, and iron are stored in placenta and released into fetal circulation
32
Hormonal production
produced by syncytiotrophoblast of placenta: human chorionic gondatropin, estrogens, progesterone
33
velamentous placenta
umbilical cord insertion on the surface of the placenta in the membranes
34
Battledore insertion
the insertion of the umbilical cord at the margin of the placenta within 10 mm of the edge What is a marginal or and eccentric insertion
35
What is the primary cause of placentomegaly
maternal diabetes
36
Placenta accrete
superficially to myometrium; Mild
37
Placenta increta
Deep into myometrium; Moderate
38
Placenta percreta
Through the myometrium; Severe
39
Accessory lobe of the placenta
Succenturiate Placenta this incidence occurs in 3% to 6% of pregnancies
40
Low pressure bleed of the placenta
marginal abruption result
41
Marginal previa
Most common type does not cover the CX OS but its edge come tot he margin ofthe OS
42
Partial previa
only partially covers the internal OS
43
complete/total previa
CX internal OS is completely covered 20% of patients with placental previa
44
low lying previa
placental edge is within 5cm of center of CX internal OS
45
maternal abnormalities demonstrate a small placenta
Intrauterine growth restriction, Intrauterine infection, Aneuploidy
46
What maternal abnormalities demonstrate a large placenta
Maternal diabetes, Maternal anemia, α-Thalassemia, Rh sensitivity, Fetomaternal hemorrhage, Chronic intrauterine infections, Twin-twin transfusion syndrome, Congenital neoplasms, Fetal malformations
47
Vasa previa
placenta covering the cervix, cord insertion at cervix
48
Circumvallate Placenta
condition where the chorionic plate is smaller than the basal plate, the margin is raised with a rolled edge
49
Circummarginate Placenta
the chorionic place of the placenta is smaller than the basal plate, with a flas interface between the fetal membrane and the placenta
50
Chorion frondosum
Portion of chorion that develops into fetal portion of placenta Site where water exchanged freely between fetal blood and AF across amnion
51
Highest level of Amniotic fluid
By 20 weeks’ gestation, AF volume increases by 10 ml/day Fluid produced by fetal urination slightly exceeds amount removed by fetal swallowing
52
Amount of AF regulated by
Production of fluid Removal of fluid by swallowing Fluid exchange within lungs Membranes and cord
53
Know conditions that associate with polyhydraminos
often associated with central nervous system (CNS) disorders and/or gastrointestinal (GI) problems, CNS disorders cause depressed swallowing, GI abnormalities result in ineffective swallowing that are often caused by a blockage (atresia) of the esophagus, stomach, duodenum, or small bowel.
54
conditions that associate with oligo
Congenital anomalies , IUGR, Postterm pregnancies, Rupture of membranes (ROM), Iatrogenesis, Hypertension, Preeclampsia , Chronic cardiac or renal disease, Connective tissue disorders , Patients receiving indomethacin
55
Role of Amniotic Fluid
Allows fetus to move freely within amniotic cavity Maintains intrauterine temperature Protects developing fetus from injury
56
diabetes
If a patient has persistent polyhydraminos what is the cause
57
eyeball
How do sonographers typically evaluate AF
58
What is the debris of the AF
vernix caseosa particulate matter, intra-amniotic blood, intrauterine meconium passage
59
Nitrazine test fern test
Patients suspected to have ROM present clinically with sudden gush or leaking of fluid. test used as screening test to determine presence of AF in vaginal secretions Patient is checked for cervical dilatation and for leaking of fluid with coughing or fundal pressure
60
Amniotic Band Syndrome
Is associated with abnormality in fetal membranes Is a common, non-recurrent cause of various fetal malformations involving limbs, craniofacial region, trunk
61
Amniotic Sheets, shelves or folds
identified as echogenic, nonfloating bands crossing through amniotic cavity Are thicker than bands associated with amniotic band syndrome Do not cause fetal malformations Most likely signify uterine synechiae
62
Hydrops
Disparity between amounts of serous fluid being produced and absorbed
63
Hydrops indications
Pleural effusions Ascites Cardiac effusion Skin edema Anasarca
64
Hydrops fetal findings
Enlarged umbilical cord Polyhydramnios Placental edema Enlarged liver and spleen In many cases, highly associated with mortality
65
Immune Hydrops
Is associated with alloimmune hemolytic disease (erythroblastosis fetalis) or rhesus (Rh) isoimmunization Maternal blood sampling and history of previously affected fetus extremely important for pregnancy management
66
Nonimmune Hydrops
Presence of abnormal accumulations of fluid in fetal body and/or skin Is associated with numerous conditions and causes
67
Nonimmune Hydrops causes
May be sporadic condition or associated with numerous other causes Cardiac insufficiency one of the most common causes Cardiac insufficiency can result from cardiac anomalies (tumors) or arrhythmias (tachycardia)
68
Nonimmune Hydrops anomalies
Fetal tumors (heart or liver) Cardiac anomalies Cystic adenomatoid malformation of lung Chorioangioma of placenta
69
Chorion frondosum
the non villious part of the chrion around the gestational sac
