Sonographic association of polycystic ovaries with intraovarian arterial pulsatility and resistive index

Abstract

The aim of the research is to know the sonographic association of polycystic ovaries with intraovarian arterial pulsatility index (PI) and resistive index (RI).We observed the PI and resistive index (RI) of 50 polycystic ovarian syndrome (PCOS) and 50 normal individuals. Polycystic ovary was seen with gray scale transabdominal and endo-vaginal sonography and labeled according to the developed sonographic criteria. The results were correlated and cross tabulated with independent sample t-test to determine the existing relationship among them. According to the results, PI and RI of the intraovarian artery were seen to decreases during PCOS as compared with the PI and RI of normal group women at the follicular phase. In case of polycystic ovary, the stroma undergoes hyperstimulation as a result of vascular remodeling and hypervascularity. It is concluded that Doppler analysis is very helpful in the diagnosis of PCOS and to give detailed information about the pathophysiology of the hemodynamics of diseased ovary.

摘要：

本文章的目的是了解多囊卵综合征患者的卵巢内动脉搏动指数(PI)和阻力指数(RI)情况。我们观察了50例多囊卵巢综合征(PCOS)患者和50例正常人的PI和RI。多囊卵巢综合征患者用经腹部和经阴道内灰阶超声检查, 并根据制定的超声标准进行标记。将研究结果进行相关性分析, 用独立样本t检验进行相关和交叉制表, 以确定它们之间存在的关系。结果显示, 卵巢内动脉的PI和RI在卵泡期时PCOS患者较正常组女性降低。多囊卵巢患者由于血管重塑和血管增生, 间质受到过度刺激。结论：多普勒分析对PCOS的诊断非常有帮助, 并能提供有关病变卵巢血流动力学的病理生理学的详细信息。
