Expectant management of cesarean scar pregnancy in 13 patients

Abstract

Objective

To monitor Cesarean scar pregnancy (CSP) patients preferring to continue their pregnancy and analyze their clinical characteristics as well as maternal and fetal outcomes.

Methods

A retrospective cohort study including 13 pregnant women diagnosed with CSP (including types I, II, III) and continued their pregnancy with cautious monitoring at Peking University First Hospital between January, 2014 and December, 2018.

Results

8/13 (61.5%) of them delivered after 28 weeks and finally gave birth to healthy babies with 3 term births and 5 preterm births (one of them which suspected placenta percreta received hysterectomy for massive bleeding and hemorrhagic shock at 34 weeks). 2/13 (15.4%) of them terminated their pregnancy at second trimester by Cesarean section for ultrasonic manifestation of placenta percreta with or without threatened uterine rupture. 1/13 (7.7%) of them went through induced labor due to inevitable abortion and needed dilatation and evacuation afterwards at 20 weeks. 2/13 (15.4%) of those patients with twin pregnancy chose fetal reduction to keep the non-CSP fetus at 8 weeks and 11 weeks. No maternal or fetal death was observed.

Conclusions

During expectant management, type I CSP patients were at little risk for developing into placenta percreta and rather save for continue pregnancy to having babies. Type II and type III CSP patients usually ended up with placenta percreta and better terminated their pregnancy immediately.
