Results of endovascular treatment in cases of abnormal placentation with post-partum hemorrhage.

AIM

The purpose of this study was to evaluate the clinical success of selective arterial embolization in cases of post-partum hemorrhage due to abnormal placentation.

METHODS

Six patients with persistent hemorrhage and abnormal placental implantation underwent uterine artery embolization over a period of three years.

RESULTS

In four patients, the placenta was left in place after a gentle attempt at removal and post-partum hemorrhage was controlled during or shortly after the procedure. In all cases, embolization was possible even when there was previous arterial ligation (two cases). In one case, a hysterectomy was required at 21 d later due to uterus and bladder necrosis. Arterial embolization in cases of abnormal placental implantation remains an uncommon treatment and is less efficient in these cases than in normal placental implantation.

CONCLUSION

Our results confirmed that even in cases of moderate bleeding, conservation treatment and embolization are possible, but that complications may be more common than in normal placentation.
