Ultrasound diagnosis of uterine myomas and complications in pregnancy

Objective: To evaluate myomas for ultrasound-documented size, location, position, and relation to the placenta, and to relate these findings to complications during pregnancy, at delivery, and in the puerperium. Methods: Among 12,708 pregnant patients who had ultrasound scans, 492 had uterine myomas. Single myomas were found in 88% of cases and multiple myomas in 12%. The myomas were evaluated for size, number, position, location, relationship to the placenta, and echogenic structure, and the outcome of pregnancy was compared to that of patients in the control group. Results: A statistically significant increased incidence of threatened abortion, threatened preterm delivery, abruptio placentae, and pelvic pain was observed in patients with uterine myomas (P<.001)
