Pulsed colour-Doppler imaging in the latest development in transvaginal sonography. Our objective is to study the uterine and ovarian perfusion during the menstrual cycle in normal fertile conditions. We studied 11 healthy volunteer women free of hormonal treatment. All studies were performed by the same operator, with the same sonograph. Measurements are made in the uterine arteries and their branches (arcuate, radial, spiral arteries) and in the ovarian vessels. The resistance index of Pourcelot (RI = [sequence: see text]) is used as reference. The statistic test is the non-parametric test of Kruskall-Wallis. The uterine and ovarian vascularization varied greatly during the menstrual cycle. Blood flow increased significantly in the luteal phase in the uterine arteries and their branches even in the active ovarian arteries. So, in the uterine artery, the RI was 0.43 in the follicular phase, 0.50 during the ovulatory peak, and 0.41 in the luteal phase. These variations were significant (p = 0.04). These results were the same all along the uterine artery. In the acurate arteries, the RI was respectively 0.75, 0.93, 0.72 at the same time of the menstrual cycle (p = 0.04). In an anovulatory cycle, blood flow remained unchanged and the arterial compliance remained stable. Quick and reproductible blood flow measurements are possible with transvaginal colour-Doppler. Millimetric vessels such as arcuate, radial and spiral arteries can be studied. This non-invasive technology can be used as a part of routine work in the management of infertility.
脉冲彩色多普勒成像技术是经阴道超声检查的最新发展成果。我们的目的是研究正常生育条件下月经周期中子宫和卵巢的血流灌注情况。我们对11名未接受激素治疗的健康志愿者女性进行了研究。所有检查均由同一名操作人员使用同一台超声仪进行。测量在子宫动脉及其分支（弓形动脉、放射状动脉、螺旋动脉）以及卵巢血管中进行。以普尔塞洛阻力指数（RI = [序列：见文本]）作为参考。统计检验采用克鲁斯卡尔 - 沃利斯非参数检验。在月经周期中，子宫和卵巢的血管化变化很大。即使在活跃的卵巢动脉中，子宫动脉及其分支在黄体期的血流量也显著增加。因此，在子宫动脉中，卵泡期的RI为0.43，排卵高峰期为0.50，黄体期为0.41。这些变化具有显著性（p = 0.04）。在整个子宫动脉中，这些结果都是一致的。在弓形动脉中，月经周期相同时间的RI分别为0.75、0.93、0.72（p = 0.04）。在无排卵周期中，血流量保持不变，动脉顺应性保持稳定。经阴道彩色多普勒能够快速且可重复地测量血流量。诸如弓形动脉、放射状动脉和螺旋动脉等毫米级血管都可以进行研究。这项非侵入性技术可作为不孕症治疗常规工作的一部分。
