The safety and effectiveness of ultrasound-guided instrumental removal of retained placenta after failed removal immediately after delivery.

OBJECTIVES

To evaluate the safety and effectiveness of ultrasound-guided instrumental removal of retained placenta.

CASE PRESENTATION: We presented a retrospective single-center cohort study include 54 patients diagnosed with retained placenta after delivery. The characteristics of the patients with retained placenta, who received ultrasound-guided instrumental removal, were evaluated. We also compared the characteristics between the patients with retained placenta with and without suspected placenta accrete.

CONCLUSION

Curettage should be performed in retained placenta without suspected placenta accrete. In retained placenta with suspected placenta accrete, we could also perform ultrasound-guided instrumental removal therapy if the retained placenta was not in the lower uterine segment or in previous scars.
