70% and 80%
Are COC or progestin only use associated with increasing or decreasing fibroid size?
Studies are mixed. Recommend monitoring size during therapy
What are pros and cons for Mirena type IUDs for treating AUB-L?
Decrease HMB
Higher rate of expulsion and vaginal spotting
How does GnRH agonist affect fibroid size?
Decreases 35-65% in 3 months
For what indication is the FDA approval for Lupron in regards to fibroids?
Pre op shrinkage of fibroids in patients with anemia. In conjunction with iron supplementation
Will fibroids grow back to original size after cessation of gnrh therapy?
Yes, within several months
After how many months of lupron treatment does add back therapy need to be added? Why?
6 months. Minimize continued bone loss and vasomotor symptoms
Role of aromatase inhibitors for fibroids?
Overall little data, some case studies say decrease size and symptoms. No FDA approval for this indication
What are potential side effects of mifepristone?
Endometrial hyperplasia without atypia (14 to 28 percent) and elevated transaminases (4%)
What are type zero type one and type two leiomyomas?
Type zero is completely in the cavity
Type of one is less than 50% intramural
Type two is more than 50% intramural
What is the success rate of removing fibroids at the initial hysteroscopy?
85 to 95%
What are the potential complications of a hysteroscopic myomectomy?

Major = events were potentially life-threatening, could lead to permanent sequelae, or required surgical intervention
What is the general complication rate for hysterectomy?

How does focused ultrasound therapy work for fibroids?
High intensity waves are directed at a specific region. Is produces focal areas of protein denaturization, irreversible cell damage, and tissue necrosis
What are potential side effects from focused ultrasound treatment for fibroids?
Heavy menstrual bleeding requiring transfusion, persistent pain and bleeding, nausea requiring hospitalization, sciatic nerve pain
What benefits are associated with preoperative GnRH agonist therapy for fibroid surgery?
When given 2-3 months pre op: improved hematologic parameters, shorter hospital stay, decrease blood loss, decrease operating time, decrease post op pain.
Does pre op GnRH agonist decrease the risk of blood transfusion for fibroid surgeries?
No
What is a disadvantage to pre op GnRH agonist (2-3 months) for fibroid surgery?
May make the leiomyomas softer and the surgical planes less distinct
What are the effects of GnRH antagonists on leiomyoma volume?
Transient reduction in leiomyoma volume by 25-40% in 19 days (more rapid effect that agonist without initial steroidal flare.
What are intraoperative measures that can be taken during myomectomy to decrease blood loss?
Infiltration of vasopression into my myometrium. Tourniquet around the lower uterine segment. For hysteroscopic myomectomy can inject vasopressin in cervix (decrease blood loss, fluid intravasation and operative time).
What percentage of women with infertility have leiomyomas?
5-10%
