In order to stabilise her haemodynamic state bilateral 10m x 4cm angioplasty balloons (Cordis) were inflated across the origins of the internal iliac arteries in the maternity unit theatre using mobile fluoroscopy (Image A). The patient was then transferred within the hour to another hospital for selective embolization. The right iliac balloon was deflated first and a selective right internal iliac arteriogram was performed using a 5 F Sos Omni catheter (Angiodynamics). Active extravasation was demonstrated from a medial branch of the right obturator artery (Image B).
