Ultrasound and the postpartum uterus

Five case reports illustrate the spectrum of ultrasound findings in the postpartum period. When examining patients with symptoms of secondary haemorrhage, the ultrasonographer may find: (i) an empty uterus (no retained tissues): (ii) blood clots which will pass spontaneously; or (iii) retained tissues, which are an indication for evacuation of the uterus. The importance of grey-scale assessment of symptomatic patients is stressed.
