Lesson 4 (Part 1) Flashcards
What are 3 congenital anomalies of the uterus?
- Arrested development
- Failure of fusion
- Failure of resorption
What are 2 examples of arrested development?
- Bilateral
- rare, uterus fails to develop or hypoplastic - Unicornuate unicollis
- Small uterus, one horn and one cervix
What are the 4 different types of unicornuate uterus?
- One tube
- One tube with just the main canal
- Has a connecting endometrium but in the wrong location
- No communicative
What fails to fuse in the congenital uterine anomaly?
The mullarian ducts
What is a result of the mullarian ducts failing to fuse? (3)
- Bicornuate unicollis
- Bicornuate bicollis
- Didelphsys
Bicornuate unicollis
Is a division of the uterus above the os
- still one uterus
Bicornuate bicollis
Is a division of the uterines os
- still one uterus
Didelphsys
Two separate uterus and cervix
- sometimes results in two separate vagina’s
What uterine anomaly is more common than didelphys?
Bicornuate
What shape is the bicornuate uterus?
Heart shaped
Can you still get pregnant with a bicornuate anomaly?
Yes
What happens if you become pregnant with a bicornuate uterus? (2)
- Growth restrictions result in preterm delivery
- Caesarean section
- C section
What can happen with diselphys in terms of pregnancy? (2)
- Can become pregnant
- rare - Can have fertility issues
What fails to get resorbed in the congenital uterine anomaly?
The median septum
Arcuate
Slight dip
What is failure to reabsorb anomaly assocaited with? (2)
- Spontaneous abortions
2. Fertility issues
What is the most common mullerian duct anomaly?
Septate uterus
How do we tell if there is an anomaly with 2D U/S?
We should see the endometrium dividing when scanning transversely through the uterus
- how far apart are the endometriums
- any irregular contours of the uterus
What is a reason for a miscarriage?
Failure of resorption
What is the treatment for the failure of resorption?
Hysteroscope laser of the septum
- non invasive procedure
What do you plan for when you have a failure of fusion?
An early pregnancy
How do you fix failure of fusion?
More invasive corrective surgery
- abdominal surgery
When would be the optimum time in a women’s menstrual cycle to scan a for a suspected uterine congenital anomaly?
Secretory because its at the biggest stage so we can see the most
Collis
Cervix
Cornuate
Cornea
What is a medium septum suppose to do?
Absorb and go away
DES
Diethylstilbestrol
What is not considered a congenital cause?
Diethylstilbestrol
What is diethylstilbestrol associated with?
Uterine anomalies
What does DES show on US? (2)
- Diffuse decrease in uterine size
2. Irregular T-shaped uterine cavity
