This study was conducted to examine the correlation between uterine
vascularity and natural history of uterine leiomyoma. Seventy women with
leiomyoma participated in this study. Measurements of uterine and leiomyoma
volume, as well as blood flow characteristics of the main uterine artery
and leiomyoma arteries, were made every 3 months for 1 year. Leiomyoma
arteries could be detected in 52 (51.5%) of 101 leiomyomas. Leiomyoma
volume increased in 24 (46.2%) of 52 leiomyomas with leiomyoma artery.
However, the leiomyoma volume increased in only three (6.1%) of 49
leiomyomas without leiomyoma artery. No difference was found between the
pulsatility index of the leiomyoma artery in the group with increased size
and in the group with stable size. This study shows the vascularity of
leiomyoma to be useful as a predictor of leiomyoma growth.
