Beard等(1984)经子宫盆腔静脉造影寻找血管异常时发现,45例经腹腔镜找不到盆腔疼痛原因的妇女中38例有中至重度充血,而没有盆腔疼痛或有盆腔疾患的妇女仅有轻度充血。这一组有慢性盆腔疼痛史而腹腔镜未找到原因,静脉造影有充血的妇女即称为盆腔疼痛综合征(PPS)。按其评分系统,5分或以上时诊断PPS有91％的敏感性及89％ Beard et al. (1984) looking for vascular abnormalities by uterine pelvic venography found that 45 of 45 women who did not have pelvic pain due to laparoscopy had moderate to severe congestion, whereas women without pelvic pain or pelvic disease had only Mild congestion. This group has a history of chronic pelvic pain and laparoscopy did not find the reason, the venous angiography is called pelvic pain syndrome (PPS). According to their scoring system, 5% or more diagnoses PPS with 91% sensitivity and 89%
