Flashcards in Congenital anomalies of the cervix Deck (14):
1

Cervical development

paramesonephric (mullerian) ducts
sixth week of development

2

2 mullerian ducts give rise to

uterine corpus, cervix, and upper vagina

3

Müllerian duct anomalies result from (4 etiologies)

nondevelopment
defective lateral
defective vertical
resorption failure

4

Most common type of mullerian fusion defect

lateral fusion defect--resulting organs may be symmetrical, asymmetrical; obstructed or unobstructed.
:Uterine septum; partial or complete

5

Vertical fusion

fusion of mullerian ducts with the urogenital sinus

6

What type of failure is characterized by a double cervix

longitudinal vaginal septum--lack of fusion

7

Single hemicervix or septate cervix composed of single muscular septum that can be an extension of a lower uterine segment or vaginal septum

Resorption failure

8

20-30% of women with mullerian duct abnormalities also have

urinary tract abnormalities.--image urinary tract if gyn abnormalities found.

9

Sex characteristics of women with mullerian duct abnormalities

Normal ovaries and normal secondary sex characteristics.

10

Rare--absent uterine cervix with a normal uterine corpus and vagina
:failure of mullerian duct canalization or abnormal epithelial proliferation after canalization

Cervical agenesis

11

absence of the cervix combined with absence of the uterine corpus and upper vagina

müllerian agenesis or Mayer-Rokitansky-Kuster-Hauser syndrome
1:4000 births

12

Cervical agenesis with normal functioning uterine corpus must be differentiated from

mullerian agenesis.
cervical agenesis leads to retrograde flow--endometriosis

13

Nonsurgical and surgical treatments to lengthen or create a vagina

vaginal dilators
McIndoe technique--neovagina
Vecchietti operation--laparoscopy
Colonovaginoplasty

14

Incomplete mullerian fusion

Duplication of reproductive structures.
