Intractable Postpartum Hemorrhage Resulting from Uterine Artery Pseudoaneurysm: Superselective Arteriographic Embolization via the Collateral Route

We present a patient with intractable postpartum hemorrhage resulting from uterine artery pseudoaneurysm despite bilateral hypogastric artery ligation who was successfully treated by an endovascular approach via the collateral route. Although there is a good argument for postponing surgery until transcatheter embolization has been attempted, this case shows that embolization can still be successful even if the iliac vessels have been ligated.
