There are multiple changes that occur in
0:03
the uterus and adnexa during pregnancy.
0:06
The first and most obvious is that the
0:08
uterus is going to increase in size, and this
0:11
happens in a pattern of predictable growth.
0:14
When patients come into the clinic,
0:15
we can measure their fundal height,
0:17
and we can estimate their gestational
0:19
age based on the size of the uterus.
0:22
Remember that hormonal support of the
0:25
pregnancy is ovarian, and up until about
0:28
10 to 12 weeks of pregnancy, progesterone
0:31
that's secreted by the corpus luteum is
0:33
going to maintain the pregnancy until the
0:36
point at which the placenta takes over.
0:39
As the uterus increases in size and
0:42
ascends into the abdomen, the abdominal
0:45
viscera, the bowel, the ovaries, are
0:48
all displaced laterally and superiorly.
0:51
We can see for this patient, who has a
0:55
third trimester pregnancy, that the uterus
0:58
has significantly increased in size
1:01
from what we saw in the cases that we
1:03
just reviewed for non-pregnant patients.
1:06
We see the fetus, which is
1:07
in cephalic presentation.
1:09
This is T2 bright amniotic fluid.
1:13
And again, we see the T2 heterogeneous
1:16
ovaries with T2 bright follicles.
1:18
So this is the right ovary
1:20
and this is the left ovary.
1:21
So we see that the ovaries have
1:22
been displaced superiorly and
1:24
laterally in the context of pregnancy.
1:27
Another change that occurs is the overall blood
1:30
volume within the maternal body increases, and
1:33
the vasculature in the pelvis proliferates
1:36
significantly to accommodate nutrient
1:39
supply and oxygen exchange with the fetus.
