ABSTRACT
Haemorrhages during pregnancy may have a non-obstetrical origin, the pregnancy itself favoring some specific aetiologies because of pregnancy-related physiological modifications. These non-obstetrical haemorrhages are rare but are associated with a high maternal and foetal mortality. The prognosis depends on an early diagnosis and a multidisciplinary approach. We report the case of a patient who had a caesarean section for suspicion of acute foetal distress during which was found a large intraperitoneal bleeding due to rupture of an unknown splenic artery aneurysm. We discuss the principal causes of non-obstetrical intra-abdominal bleeding, including subcapsular liver haematoma, rupture of uterine vessels and rupture of splenic artery aneurysm, with a specific focus on this last aetiology.
