3-D ultrasound reveals effects of surgery for PCOS

Using three-dimensional color power angiography to image women before and after ovarian electrocautery for PCOS.
MedWire News: Transvaginal ultrasound can offer valuable insights into the impact of electrocauterization in women with polycystic ovary syndrome (PCOS), European investigators believe.
Their conclusion is based on a clinical study involving 10 women with PCOS scheduled to undergo laparoscopic ovarian electrocautery. The women were studied before and after surgery using transvaginal three-dimensional (3-D) ultrasound equipped with a color Doppler angiography-based, computed-aided histogram analysis.
This new imaging technique allows a detailed characterization of ovarian volume, stromal vascularity, and intraovarian blood flow, explain Miklós Vizer (University of Pécs, Hungary) and co-authors.
Ovarian electrocautery was associated with a significant decrease in ovarian volume (mean –3.272 cm3 at 1 week) and significant increases in vascularization and blood flow.
Serum and urinary hormone profiles also changed after surgery, with reductions in luteinizing hormone and testosterone levels and an increase in follicle-stimulating-hormone levels.
Significantly, the change in sonographic parameters was highly correlated with the change in hormone levels, suggesting that 3-D ultrasound might be a useful adjunct and noninvasive method for assessing women with PCOS.
“It appears that changes in ovarian volume and blood flow parameters after laparoscopic ovarian electrocauterization contribute to and partly explain hormonal alterations and the consequent clinical results,” Vizer and team remark.
