Chapter 4 — Postmenopausal Sonography Flashcards
These gradually become unresponsive to the gonadotropins as a women ages and stops producing progesterone estradiol and significant levels of estrogen. These also atrophy and decrease in size with disappearance of follicles over subsequent few years
Ovaries
Menses become irregular and generally ceases between what year of age
45-55 years of age
Postmenopausal bleeding may be due to what
Atrophic endometrium
Normal anatomy sono findings
- uterine and cervical contours and proportions are maintained
- myometrium may have calcified arcuate arteries
- small amount of fluid in the endometrium cavity (hydrometric is considered normal in an asymptomatic patient this is often caused by cervical stenosis
A normal endometrial stripe is less than _____ in asymptomatic patient
8mm
Asymptomatic = no vaginal bleeding
Decreased estrogen levels = thinner or thicker endometrial stripe?
Thinner
_____ mm is considered upper limits of normal, if there is a history of bleeding
4-5mm
In patients receiving sequential estrogen/progesterone replacement, the endometrium resembles ____________ cyclic endometrium and measuring up to _____ mm
Pre-menopausal
8mm
Administration of estrogen and progesterone may help alleviate some of the symptoms associated with menopause and can help prevent severe osteoporosis
Unopposed estrogen is associated with increased risk of hyperplasia and endometrial carcinoma and typically not used without progesterone/progestins
Women may take cycling (___________) doses of estrogen and progesterone which will cause the endometrium to ______ during the estrogen phase and ______ during the progesterone phase
Sequential
Thicken
Thin
Some women are given continuous combination dowse of estrogen and progesterone; in those women the endometrium doesn’t cycle between thicker and thinner phases
Sono findings with hormone replacement
- endo stripe up to 8mm of unopposed estrogen only
- endo stripe up to 10-12mm in estrogen phase decreases during progesterone phase ( us after progesterone withdrawal - after bleeding)
- cyclic hormones = menstrual type endo
- continuous combined hormones <8mm
Bleeding from genitalia tract of an older women that occurs more than 12 months after LMP is considered
Postmenopausal bleeding
Most common cause of postmenopausal bleeding is
Exogenous estrogen administration
