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.
本研究旨在探讨子宫血管状况与子宫肌瘤自然病程之间的相关性。70例子宫肌瘤患者参与了本研究。在1年的时间里，每3个月对子宫和肌瘤体积以及子宫主要动脉和肌瘤动脉的血流特征进行测量。在101个肌瘤中，有52个（51.5%）可检测到肌瘤动脉。在52个有肌瘤动脉的肌瘤中，24个（46.2%）肌瘤体积增大。然而，在49个没有肌瘤动脉的肌瘤中，只有3个（6.1%）肌瘤体积增大。肌瘤体积增大组与稳定组的肌瘤动脉搏动指数之间没有差异。本研究表明，肌瘤的血管状况可作为肌瘤生长的预测指标。
