Rupture of pseudoaneurysm after vaginal delivery successfully treated by selective arterial embolization.

BACKGROUND

Rupture of a pseudoaneurysm after vaginal delivery is a rare cause of postpartum hemorrhage.

CASE: A 29-year-old primigravida delivered a healthy boy by vacuum extraction at 38 weeks of gestation. The patient underwent repair of a right mediolateral episiotomy and left vaginal wall laceration. On the third postpartum day she experienced massive vaginal bleeding with vaginal wall laceration, and the vaginal bleeding progressively increased. A selective angiogram of the left internal iliac artery showed a pseudoaneurysm with extravasation originating from the left internal pudendal artery. Complete occlusion of the pseudoaneurysm was achieved by embolization of the left internal pudendal artery. The postprocedural course was uneventful.

CONCLUSION

A pseudoaneurysm should be considered in unclear cases of postpartum hemorrhage.
