A circumvallate placenta can only be demonstrated during what
portion of pregnancy? - ANSWER-Mid second trimester
Early in pregnancy, the entire surface of the gestational sack is
covered with the ViLLI, as the pregnancy progresses, the VEILLi
usually regress over most of the surface of the sac, and that
remains becomes the placenta. If this regression does not occur,
the placenta may cover the entire surface of the sack, if it is
patchy, there may be two or more separate areas of placenta
formation. And either case, this is called what? - ANSWER-
Placenta membranacea
Placenta membranacea - ANSWER-Fetal membranes covered by
chorionic villi due to failure of chorion differentiation into the
chorion laeve and chorion frondosum

Succenturiate lobe - ANSWER-Accessory lobe of placenta
located away from the main placenta body. It is connected to the
main placenta via large blood vessels That course through the
membranes that accompany it
Bipartite lobe - ANSWER-Is one that is divided into two
approximately equal size lives in is sometimes called but I bilobed
placenta
Annular placenta - ANSWER-A ring shaped placenta that attaches
circumferentially to the myometrium.
Between succentruriateblobes, bipartite placenta, and annular
placenta which types of placentas are seen on ultrasound and
which are not? - ANSWER-Succenturiateblobes and bipartite
placentas are seen on ultrasound. And annular placenta is not
seen on ultrasound.
Sonographic findings of succenturiateblobes and bipartite
placentas - ANSWER--two masses of placenta tissue that appear
unconnected. -Color Doppler imaging will show robust flow in the

blood vessels that vascularize the accessory lobe. - when the
lines are of equal size, the primary lobe can be identified by the
presence of the umbilical cord insertion on its chorionic surface.
After 33 weeks, more that 50% of placentas contain some degree
of calcification. - ANSWER-Calicifation is a normal part of
placental aging ( fact card)
Where are calcifications usually found on the placenta? -
ANSWER-At the base of the placenta, in the septa, and in the
subchorionic and perivillous spaces.
Calcification of the placenta is more common in women with
what? - ANSWER--low parity-smoke cigarettes-mothers who have
thrombotic disorders and are on anticoagulants such as heparin
or aspirin therapy. Coumadin crosses placenta discontinued first
trimester due to fetal abnormalities correlation
Subchorionic hematoma - ANSWER-bleeding btw the
endometrium and the gestational sac.

- Pts are managed expectantly until symptoms resolve or
additional findings develop
Subchorionic lesions and cystic or hypoechoic areas immediately
under the chorionic membrane adjacent to the fetal surface of the
placenta are typically acute or chronic areas of - ANSWER-
Thrombus
Are subchorionic lesions and cyst a significant finding in terms of
the placenta? - ANSWER-No they are insignificant.
Sonographic findings of subchorionic thrombotic lesions -
ANSWER-Echogenic focus beneath the chorionic plate
Sonographic findings of subchorionic cystic lesions - ANSWER-
Well circumscribed, anechoic areas beneath the chorionic plate
Most hypoechoic or cystic areas in the mid placenta are due to -
ANSWER-Intervillous thrombus in the space between the fetal
and the maternal sides of the placenta.
