目的：探讨盆腔平滑肌瘤瘤体内动脉血流的内在规律和临床意义。方法：采用彩色多普勒血流显像（ＣＤＦＩ）观察８５例盆腔平滑肌瘤瘤体内动脉血流情况。结果：动脉血流阻力指数（ＲＩ）值的高低：阔、骶韧带肌瘤组＜子宫浆膜下肌瘤组＜子宫肌壁间肌瘤组和阴道壁肌瘤组（Ｐ＜０．０１）。并发现ＲＩ值与瘤体大小呈负相关关系（ｒ＝－０．８５）。阴道壁肌瘤血流速度低于其它三组。结论：盆腔平滑肌瘤瘤体内动脉血流ＲＩ值与肿瘤的部位和大小有关，其ＲＩ值随瘤体增大有降低的趋势。大的盆腔平滑肌瘤可出现丰富的低阻力型动脉血流（ＲＩ≤０．４０），应注意与恶性肿瘤相鉴别。
Objective: To investigate the inherent regularity and clinical significance of arterial blood flow in pelvic leiomyomas. Methods: Color Doppler flow imaging (CDFI) was used to observe arterial blood flow in 85 cases of pelvic leiomyoma. RESULTS: The level of arterial flow resistance index (RI) was measured in the broad and tibial ligament fibroids group and the subuterine subserosal fibroids group, the intramural intramural fibroids group and the vaginal wall fibroids group (P<0.01). . It was found that the RI value was negatively correlated with the tumor size (r=-0.85). Vaginal wall fibroids have lower blood flow velocity than the other three groups. Conclusion: The RI value of arterial blood flow in pelvic leiomyoma tumor is related to the location and size of the tumor. The RI value of the pelvic leiomyoma tumor has a decreasing trend with the increase of tumor size. Large pelvic leiomyomas may present with abundant low-resistance arterial blood flow (RI ≤ 0.40) and should be differentiated from malignant tumors.
