Postpartum ultrasound: postpartum assessment using ultrasonography.

Postpartum haemorrhage (PPH) is a potential cause of maternal mortality, and obstetricians must be prepared to rapidly diagnose and treat this condition. Optimal treatment is dependent upon the underlying cause of haemorrhage. Ultrasonography is the most helpful tool for prompt diagnosis of PPH aetiology and obstetricians must have a strong understanding of postpartum ultrasonography. In our previous report, we demonstrated the utility of ultrasonography using the focused assessment with sonography for obstetrics (FASO) technique (a modified version of FAST) as the primary postpartum obstetric survey. In the present article, we review the ultrasonographic findings of PPH, differentiated by the underlying cause of haemorrhage, including retained placenta, morbidly adherent placenta, uterine rupture, uterine inversion and uterine artery abnormalities.
