Posterior uterine wall rupture during labour

Area of Science:

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

Background:

• Vaginal birth after Cesarean (VBAC) is a common and accepted delivery method for women without contraindications.
• Uterine rupture is a known risk during VBAC, typically associated with previous scar tissue.
• Rupture in non-scarred uterine tissue during VBAC is exceptionally rare but carries severe consequences.

Purpose of the Study:

• To report an extremely rare case of posterior uterine rupture during VBAC in a presumably normal uterine wall.
• To highlight the importance of vigilant monitoring and prompt intervention during VBAC, even in the absence of premonitory signs.
• To emphasize that isolated cases do not negate the overall safety and benefits of VBAC.

Main Methods:

• Case report of a 31-year-old woman undergoing VBAC at 38 weeks gestation.
• Detailed clinical observation of labor course and maternal response.
• Review of the literature concerning uterine rupture during VBAC.

Main Results:

• The patient experienced a posterior uterine rupture without any preceding warning signs during an uncomplicated VBAC labor.
• The rupture resulted in maternal shock and the subsequent death of the newborn seven days postpartum.
• This event occurred in a non-scarred area of the uterus, distinguishing it from typical VBAC-related ruptures.

Conclusions:

• Uterine rupture can occur during VBAC without apparent risk factors or warning signals.
• Vigilant and immediate medical response during labor is critical to mitigate the dangers of uterine rupture.
• This extremely rare case does not diminish the established safety and benefits of VBAC for appropriately selected women.
