Clinical characteristics, treatment indications and treatment algorithm for post-partum hematomas

Area of Science:

• Obstetrics and Gynecology
• Interventional Radiology
• Surgical Management

Background:

• Postpartum hematomas are severe obstetric complications with challenging treatment decisions.
• The role of transcatheter arterial embolization (TAE) in managing postpartum hematomas requires clarification.

Purpose of the Study:

• To elucidate clinical characteristics of postpartum hematomas.
• To define treatment indications for postpartum hematomas.
• To develop a treatment algorithm for postpartum hematomas based on location.

Main Methods:

• Retrospective analysis of 54 patients with postpartum hematomas.
• Hematoma classification by location: upper vaginal, lower vaginal, and vulvar.
• Collection and analysis of clinical data, including blood loss and treatment methods.

Main Results:

• Upper vaginal wall hematomas (n=5) consistently required TAE, with average blood loss of 2473 mL.
• Lower vaginal wall hematomas (n=19) were primarily treated surgically, though TAE was used in severe cases (2010 mL blood loss).
• Vulvar hematomas (n=30) did not undergo TAE; observation or surgery were employed. Observation was also an option for some lower vaginal wall hematomas.

Conclusions:

• A treatment algorithm for postpartum hematomas is proposed, emphasizing location-specific management.
• Transcatheter arterial embolization is the recommended treatment for upper vaginal wall hematomas.
• Surgery is suitable for most lower vaginal wall hematomas, with TAE considered for refractory bleeding; observation is viable for select vulvar and lower vaginal cases.
