Placenta Previa Complete Centralis Clinical Trial
Official title:
Lower Uterine Compression Sutures for the Treatment of Postpartum Hemorrhage Due to Placenta Previa Complete Centralis; Prospective Study
Objective: To assess the efficacy of lower uterine compression sutures (involved bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch) as a conservative treatment for the treatment of postpartum hemorrhage in women with placenta previa complete centralis. Method: This prospective study of 50 women with postpartum hemorrhage following removal of placenta previa complete centralis during elective cesarean section. All 50 patients will have lower uterine compression sutures (involving bilateral uterine artery ligation and compression of the lower uterine segment at the same time with one circular stitch). All patients will be followed postpartum for evaluation of uterine cavity and menstrual cycles
The investigators conduct a prospective study at Department of Obstetrics and Gynecology,
Benha University Hospital, since June 2012 till July 2014, after approval of the study
protocol by the Local Ethical Committee.
All patients provide written informed consent to undergo any procedure necessary, including
lower uterine compression suturing procedure, as an attempt to avoid hysterectomy. They also
provide written informed consent to undergo hysterectomy if all measures attempted to
preserve the uterus fail.
All patients have placenta previa (50). The inclusion criteria are a gestation age of ≥ 28
weeks and antepartum hemorrhage; intraoperative postpartum hemorrhage and discovery of a
placenta accreta; and an adherent placental part after piecemeal removal of the placenta,
with bleeding from the placental site, posterior placenta previa and/or successful piecemeal
removal of the placenta.
The first author performed all cesarean deliveries and assisted by the second author. We
open the parietal peritoneum by sharp dissection and blunt expansion, high above the
bladder, a bladder flap is made and the bladder is retracted. A small median transverse
hysterotomy incision is done in the lower uterine segment. It is expanded on both sides
using scissors, stopping shortly before the uterine arteries. Active delivery of the
placenta is attempted by searching manually for a plane of cleavage between the placenta and
the uterus after delivery of the fetus. The study technique comprise lower uterine
compression sutures (involved bilateral uterine artery ligation and compression of the lower
uterine segment at the same time with one circular stitch).
