Recovery of uterine and ovarian function in patients with complete placenta previa after caesarean delivery A retrospective study

This retrospective study was designed to explore the recovery of uterine and ovarian function in patients with complete placenta previa (PP) after caesarean delivery (CD). 136 complete placenta previa patients (group completed placenta previa) and 140 patients without complete PP (group non-PP, control group) were included in this study from Jan 2016 to Dec 2018. Subgroup analysis of patients with complete PP was made to determine the impact of different hemostatic methods used during CD on the recovery of uterine function. There were no statistically significant differences between the 2 groups in postpartum menstrual cycle changes, ovarian hormone, and uterine vascular supply as measured by pulsatility index and systolic/diastolic ratio (P > .05). However, the group with complete PP had a reduced endometrial thickness (0.47 +/- 0.11 vs 0.50 +/- 0.12, P < .001), a lower uterine resistance index at 42nd days (0.84 +/- 0.03 vs 0.90 +/- 0.03, P < .001), and a delayed resumption menstruation (7.07 +/- 2.61 vs 5.31 +/- 2.16, P < .001) when compared with control group. Subgroup analysis showed that RI index of all subgroups in completed PP group was lower, endometrial thickness was thinner and the time to menstrual recovery was longer than that of non-PP group. In conclusion, the endometrial thickness and blood supply at 42nd days, not ovarian function, maybe affected after CD in patients with complete PP.

Automated summary

This retrospective study investigated the recovery of uterine and ovarian function in patients with complete placenta previa after caesarean delivery. The endometrial thickness and blood supply at 42nd days were found to be affected, while ovarian function remained unaffected after delivery. Patients with complete PP showed thinner endometrial thickness, lower uterine resistance index, and delayed resumption of menstruation compared to those without complete PP.
