Postpartum haemorrhage, the second cause of maternal mortality in France, is an obstetric and anaesthetic emergency. Yet, it often seems avoidable as most patients at risk can be identified before or during labour. In this respect, obstetrical conduct regarding delivery is essential; it makes it possible to foresee the necessary preventive and curative measures. Once haemorrhage has begun, any delay or hesitation in assuming multidisciplinary responsibility is potentially detrimental as it may lead to coagulopathy complications. Whenever possible, arterial embolisation presents an enormous progress in noninvasive conservative treatment, especially after vaginal delivery. Stepwise uterine devascularisation seems to be a promising surgical option as it can be used under all conditions, preserves maternal fertility, and is clearly effective.
