Menstrual, fertility and psychological impacts after uterine compression sutures for postpartum hemorrhage: a prospective cohort study

Abstract

Abstract Background Uterine compression suture is an important conservative surgical technique in managing atonic postpartum hemorrhage. In this study, we aim to evaluate the subsequent menstrual, fertility and psychological outcomes after uterine compression sutures. Methods This was a prospective cohort study between 2009 and 2022 conducted in a tertiary obstetric unit (6000 deliveries per year) in Hong Kong SAR. Women with primary postpartum hemorrhage successfully treated with uterine compression sutures were followed-up in postnatal clinic for two years after delivery. Data on menstrual pattern were collected during each visit. Psychological impact after uterine compression suture was assessed using a standardized questionnaire. Subsequent pregnancies were identified by territory-wide computer registry and telephone interviews. Women with postpartum hemorrhage treated with uterotonic agents only were chosen as controls. Results In our cohort (n = 80), 87.9% of women had return of menses within six months after delivery. Regular monthly cycle was observed in 95.6% of women. Majority of women reported similar menstrual flow (75%), menstrual days (85.3%) and no change in dysmenorrhea status (88.2%) as compared before. Among eight (11.8%) women who reported hypomenorrhea after uterine compression sutures, two cases of Asherman’s syndrome were diagnosed. Among 23 subsequent pregnancies (16 livebirths), no significant differences in outcome were observed except more omental or bowel adhesions (37.5% vs 8.8%, p = 0.007), recurrence of hemorrhage (68.8% vs 7.5%, p < 0.001) and repeated compression sutures (12.5% vs 0%, p = 0.024) were seen in women with previous compression sutures. Over half of the couple declined future fertility after uterine compression sutures with 38.2% of women recalled unpleasant memories and 22.1% reported life-long adverse impact especially tokophobia. Conclusion Majority of women with history of uterine compression sutures had similar menstruation and pregnancy outcomes as compared to those who did not have sutures. However, they had higher intrapartum risk of visceral adhesions, recurrence of hemorrhage and repeated compression sutures next pregnancy. Furthermore, couple could be more susceptible to negative emotional impact.
