The tissue preparations of the pelvic veins obtained during laparoscopy were examined. The expression of markers of proliferation (Ki-67), apoptosis (p53), and angiogenesis (CD31, CD34), as well as estrogen and progesterone receptors in women with pelvic varicose veins was assessed by the immunohistochemical method. A decrease in the median expression of the proliferation marker (Ki-67) and estrogen and progesterone receptors and simultaneous increase in the expression of apoptosis marker (p53) and activation of angiogenesis processes (markers CD31 and CD34) were observed with increasing the severity of the disease. These data extend our understanding of the pathogenetic mechanisms of pelvic varicose veins and contribute to the development of methods of pathogenetically based targeted therapy.

Objective: The study aims to elucidate clinical and ultrasonographic characteristics of female patients diagnosed with pelvic varicose veins (PVV) and to assess potential risk factors associated with incidences of chronic pelvic pain (CPP) in this population.
Methods: Clinical and ultrasound data were retrospectively collected from female patients with PVV at Beijing Shijitan Hospital between December 2017 and October 2022. Patient cohorts were divided into two groups based on whether they had been experiencing non-periodic pelvic pain over six months, consistent with the symptoms of CPP.

However, PCS is poorly understood, underdiagnosed and undertreated, with the average time to diagnosis being reported as up to four years after initial presentation.
