[Uterine artery false aneurysm after caesarean delivery: an uncommon cause of post-partum haemorrhage].

We describe a case of late post-partum haemorrhage from uterine artery pseudo-aneurysm secondary to the vascular trauma induced by a previous caesarean section. This rare aetiology should be known by anaesthesiologists since treatment by arterial embolization is safe and effective whereas curettage usually recommended for primary post-partum haemorrhage can aggravate the bleeding. This diagnosis should be considered in front of late genital bleeding without obvious cause and lead to perform a sonographic examination with Doppler-scan before diagnostic and therapeutic arteriography, eventually preceded by diagnostic MRI. 2010 Elsevier Masson SAS.
