Maternal and Fetal Outcomes after Multiple Cesarean Deliveries

Area of Science:

• Obstetrics and Gynecology
• Maternal-Fetal Medicine
• Surgical Outcomes

Background:

• Cesarean delivery (CD) is common, but risks escalate with each subsequent procedure.
• Multiple CDs (≥4) are infrequent but pose unique challenges.
• Understanding risks associated with multiple CDs is crucial for patient counseling and management.

Purpose of the Study:

• To compare obstetric hemorrhage and other maternal/neonatal complications between women undergoing a fourth or more Cesarean delivery (CD) versus a third CD.
• To assess specific surgical risks associated with multiple Cesarean deliveries.

Main Methods:

• Retrospective cohort study of 161 pregnant women with ≥2 prior CDs.
• Comparison of outcomes between a group undergoing ≥4 CDs and a group undergoing a third CD.
• Analysis of primary endpoint: obstetric hemorrhage rate; secondary endpoints: dehiscence, hysterectomy, surgical difficulties, adhesions, maternal-neonatal complications.

Main Results:

• Hemorrhage and transfusion rates were similar between groups (7% vs 10% and 3% vs 8%, respectively).
• Higher risks observed in the multiple CD group (≥4) included uterine segment dehiscence (24% vs 6%), hysterectomy (6.6% vs 0%), difficult abdominal opening (82% vs 49%), peritoneal adhesions (22% vs 3%), and difficult bladder separation (73% vs 36%).
• No cases of uterine rupture or maternal-neonatal mortality were reported in either group.

Conclusions:

• While multiple Cesarean deliveries (≥4) are associated with increased surgical complications like dehiscence and adhesions, they do not elevate hemorrhage or transfusion rates compared to a third CD.
• Despite potential surgical challenges, maternal and neonatal outcomes following multiple Cesarean deliveries are generally favorable.
• This study provides valuable data on the safety of multiple Cesarean deliveries in a specific clinical setting.
