Uterine artery pseudoaneurysm (UAP) is a rare cause of secondary postpartum haemorrhage.
UAP usually presents as delayed (secondary) postpartum haemorrhage, that is per vaginal bleeding which occurs more than 24 hours and up to 6 weeks postpartum. However, some reported cases have been shown to present more than 6 weeks after delivery.
Pseudoaneurysms are a blood-filled cavity communicating with the lumen of the parent artery due to deficiency of one or more layers of an arterial wall (i.e. it does not have all the three arterial wall layers). In contrast, true aneurysms contain all the three layers of the arterial wall.
Treatment and prognosis
Most of the cases in the English literature have been successfully treated with uterine artery embolisation (UAE). Without early recognition and treatment, UAP can be extremely deleterious.
