Placenta percreta and uterine rupture at 16 weeks

Area of Science:

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

Background:

• Placenta percreta is a severe obstetric complication associated with high rates of maternal morbidity and mortality.
• Spontaneous uterine rupture in the first trimester due to placenta percreta is an exceptionally rare event.

Observation:

• A viable pregnancy at 16 weeks gestation presented with shock, acute abdomen, and hemoperitoneum.
• Initial ultrasound findings were misleadingly normal, complicating the diagnosis.
• The patient had a history of cesarean section and dilatation and curettage, known risk factors for placenta percreta.

Findings:

• The patient experienced a spontaneous fundal uterine rupture.
• Exploratory laparotomy revealed the uterine rupture, which was successfully managed with uterine repair.
• Diagnosis was challenging due to the rarity of the condition and confusing clinical presentation.

Implications:

• This case highlights the critical importance of rapid clinical suspicion and immediate surgical intervention in suspected uterine rupture.
• Early diagnosis and management are vital for improving maternal outcomes in rare but life-threatening obstetric complications like placenta percreta.
• Risk factors such as prior uterine surgeries necessitate heightened awareness for placenta percreta in subsequent pregnancies.
