Fertility
Distortion of the intrauterine cavity can result in reproductive difficulties.
Fibroids and pregnancy
Incidence of Fibroids during Pregnancy
Effect of Pregnancy on Fibroids
Fibroid Degeneration during Pregnancy
- More likely to degenerate during pregnancy b/c myometrial blood flow shifts toward the developing fetus and placenta.
- Red degeneration
- ?? ?? hemorrhagic infarction
- Severe pain, tenderness, fever
- Ultrasound
- Conservatively managed with acute pain control
- eg, indomethacin for patients <32 weeks gestation
- codein ???? ??.
