Association of menstrual blood volume and reproductive outcomes in patients with caesarean scar pregnancy managed using uterine artery embolization and curettage

Abstract

This study aimed to assess the association of menstrual blood volumes (MBV) and reproductive outcomes in patients after uterine artery embolization (UAE) combined with curettage for caesarean scar pregnancy (CSP). This retrospective observational study enrolled women who underwent UAE plus curettage for CSP at the Interventional Department of Henan Provincial People’s Hospital between December 2012 and December 2017. The primary outcome was pregnancy rate and the secondary outcomes were live birth rate (LBR) and interpregnancy interval. This study finally included 37 women (16 women with normal MBV and 21 women with decreased MBV) with pregnancy intention after UAE plus curettage for CSP. The pregnancy rate in women with normal MBV was higher than those with decreased MBV (81.3% vs. 47.6%; P = 0.048). There were no differences between the two groups regarding the interpregnancy interval (18.4 ± 8.7 vs. 22.2 ± 10.0 months, P = 0.233), and LBR (63% vs. 38%, P = 0.191). In conclusion, Women with normal MBV after UAE combined with curettage for CSP management might have a higher pregnancy rate compared with patients with decreased MBV, but there were no differences in LBR between the two groups.
