Abstract
PurposeTo evaluate the feasibility and efficacy of embolization of the round ligament arteries in the management of postpartum hemorrhage. Materials and MethodsEleven women (mean age, 31 y) underwent round ligament artery because of persistent or recurrent hemorrhage after initial uterine or internal iliac artery embolization. ResultsA total of 16 round ligament arteries were embolized. The round ligament artery arose from the inferior epigastric artery in 11 cases (69%) and directly from the external iliac artery in 5 (31%). Embolization was performed with calibrated microspheres in 7 women (63%) and gelatin sponge pledgets in 4 (37%). Coils were used in addition to gelatin sponge pledgets in 3 patients. Hemostasis was achieved in 10 patients (91%), and 1 required additional conservative surgery. The mean hemoglobin level before embolization was 7.2 g/dL ± 1 and increased significantly on day 1 after embolization (10.3 g/dL ± 1.0; P < .05). No procedure-related complication was reported. The mean hospital stay was 5.6 days ± 2. Two patients had further pregnancies 13 and 14 months after embolization. ConclusionsSelective embolization of the round ligament artery is a safe and effective treatment for obstetric hemorrhage. It should be considered in cases of persistent or recurrent bleeding after initial uterine or internal iliac artery embolization.
