Uterine Artery Embolization for Primary Postpartum Hemorrhage

Area of Science:

• Obstetrics and Gynecology
• Interventional Radiology
• Maternal Health

Background:

• Postpartum hemorrhage (PPH) is a significant cause of maternal morbidity and mortality worldwide.
• Defined as >500mL blood loss (vaginal) or >1000mL (C-section), PPH affects up to 10% of deliveries.
• Primary PPH occurs within 24 hours of birth and can lead to shock, DIC, and death.

Purpose of the Study:

• To review the management of primary postpartum hemorrhage.
• To highlight the role of angiography and trans-catheter embolization in controlling PPH.
• To evaluate embolization as an alternative to hysterectomy.

Main Methods:

• Review of literature on primary postpartum hemorrhage management.
• Focus on interventional radiology techniques, specifically angiography and embolization.
• Comparison of embolization outcomes with traditional obstetric maneuvers and hysterectomy.

Main Results:

• Uterine atony, lacerations, and arterial injuries are common causes of PPH.
• Standard management includes uterotonics, massage, and balloon tamponade.
• Angiography and embolization are effective in controlling PPH from various etiologies.
• Embolization demonstrates high clinical success rates and preserves future fertility.

Conclusions:

• Primary postpartum hemorrhage requires prompt and effective management.
• Trans-catheter embolization is a valuable, fertility-sparing alternative to hysterectomy for refractory PPH.
• Embolization offers high success rates and supports future reproductive potential.
