健康育龄女性盆腔静脉MRI研究
MRI study of pelvic veins of healthy women in their reproductive years
目的 建立健康育龄女性左侧卵巢静脉和盆腔静脉参考值，为诊断盆腔静脉淤血综合征及相关疾病提供依据。 方法 符合纳入标准62例健康育龄女性志愿者，年龄21岁～45岁。入组对象按是否生育分为2组，经产组30例，未产组32例。均行盆腔MRI平扫和MRA检查，测量左侧卵巢静脉及盆腔静脉直径，分析经产组与未产组间有无统计学差异。 结果 62例健康育龄女性左侧卵巢静脉直径为（4.45±0.59）mm，其中经产组为（4.87±0.45）mm，未产组为(4.06±0.42)mm，二者之间统计学上有显著性差异（t=7.297, P<0.001）。盆腔静脉直径为(4.17±0.58)mm，其中经产组为(4.45±0.48)mm，未产组为(3.91± 0.54)mm，经产组和未产组之间统计学上有显著性差异（t=6.400, P<0.001）。 结论 经产育龄妇女与未产育龄妇女左侧卵巢静脉和盆腔静脉有差异，临床医师诊断盆腔静脉相关疾病时需参考不同数值。
Objective To study MRI features of pelvic veins of healthy women in their reproductive years and to familiarize radiologists with anatomy of pelvic veins. Methods 62 healthy women in their reproductive years, 21~45 years, including 30 parous women and 32 nonparous women. MRI and MRA was performed, to measure the diameter of left ovarian vein and pelvic veins, analyses statistically, and investigate MRI appearance of healthy women in their reproductive years. Results Pelvic veins in 62 healthy women were showed by MRI and MRA. The mean diameter of left ovarian vein was（4.45±0.59）mm, (4.87±0.45) mm in the parous women group, (4.06±0.42)mm in the nonparous women group, There were significant differences between two groups (t=7.297, P<0.001). The mean diameter of pelvic vein was (4.17±0.58) mm, (4.45±0.48) mm in the parous women group, (3.91±0.54) mm in the nonporous women group, There were significant differences between two groups (t=6.400, P<0.001). Conclusion Pelvic veins were showed by MRI and MRA clearly, There were significant differences between parous women and nonparous women.
