Post-partum hemorrhage is the leading cause of maternal mortality, ranging from 18 to 50% of deaths worldwide. The puerperal hematoma is an unusual cause (also called peri-genital thrombi) with a frequency of 1/1000. They are formed in a paravaginal, paracervical or parametrial connective detachment, after vascular lesions. There are many favorable factors: primiparity, instrumental extraction, macrosomia, multiple pregnancies, vulvovaginalvarices, difficult hemostasis, coagulation anomalies, and prolonged dilation. The “active” treatment of puerperal hematoma is based on surgery and/or arterial embolization.
