Uterine artery pseudoaneurysm haemorrhage requiring semi-urgent caesarean section: a multidisciplinary approach

A uterine artery pseudoaneurysm is a rare cause of blood loss during pregnancy. Pseudoaneurysms typically occur after damage to the arterial wall resulting in a contained haemorrhage that can potentially lead to an uncontrolled haemorrhage. The condition can be life-threatening for both the mother and the foetus. A medical intervention such as the thrombin injection has been described in the post-partum setting, though it remains controversial (Parker et al. 2017). There are a few case reports describing uterine artery malformations in the pregnant patient (Kim et al. 2014). There are even fewer case reports describing a temporary balloon occlusion for an emergent caesarean section followed by a uterine artery embolisation. In this case report, a temporary balloon occlusion provided adequate haemorrhagic control in the acute setting when a semi-urgent caesarean section was required. The patient was opposed to the idea of hysterectomy as she wished to preserve her future fertility. Therefore, a selective embolisation was completed after a successful delivery (Vilos et al. 2009; Zhang et al. 2015).
