[Limits to arterial embolization treatment of severe postpartum hemorrhage].

OBJECTIVE
To assess the limits of arterial embolization in the management of serious postpartum haemorrhage (PPH).


STUDY DESIGN
Retrospective study.


PATIENTS AND METHODS
We examined the cases of 29 patients admitted to intensive care units of Rouen University Hospital for PPH between January 1994 and August 1999. Demographic, obstetrical and biological data, the required treatment and eventual side effects were collected and analysed using the appropriate parametric and non parametric tests.


RESULTS
Arterial embolization was carried out on 15 patients (52%) with a success rate of 73%. Of the 14 other patients, 11 underwent conservative or radical surgery without further complications, three received medical treatment. No maternal death occurred; however, one patient transferred from a local hospital and already presenting haemodynamic instability suffered cardiac arrest before embolization. Arterial embolization was unsuccessful in four cases, two of which were cases of placenta accreta. These patients were older (p < 0.05) and all had a past history of curettage and/or caesarean section for preceding deliveries (p < 0.01).


CONCLUSIONS
Emergency arterial embolization is a valuable therapy in case of PPH but can only be carried out in specialised units. Obstetrical antecedents would appear to constitute a major risk factor and transfer increases the morbidity rate.
