Selective arterial embolization of the uterine arteries in the management of intractable post-partum hemorrhage.
BACKGROUND
To evaluate the efficacy and safety of selective arterial embolization in the management of intractable post-partum hemorrhage.


METHODS
Thirty-five consecutive women with severe post-partum hemorrhage (primary, n=25; secondary, n=10) were treated by selective embolization of the uterine arteries. The main cause of immediate post-partum hemorrhage was atonic uterus. Retained placental fragments with endometritis was the main cause of delayed hemorrhage. In all cases, hemostatic embolization was performed because of intractable hemorrhage. Hysterectomy had been performed in two cases before embolization but it had also failed to stop the bleeding.


RESULTS
Angiography revealed extravasation in ten cases, spasm of the internal iliac artery in four cases, false aneurysm in two cases and arteriovenous fistula in one case. After embolization, immediate cessation or dramatic diminution of bleeding was observed in all cases. Two patients required repeated embolization the following day. No major complication related to embolization was found. In one patient with placenta accreta, delayed hysterectomy was necessary. Normal menstruation resumed in all women but two who had hysterectomy. One woman became pregnant after embolization.


CONCLUSIONS
Selective emergency arterial embolization is an effective means of controlling severe post-partum hemorrhage. This procedure avoids high risk surgery and maintains reproductive ability.
