Overview

Objective:
To evaluate accuracy of placenta accreta ultrasound prediction in own group of patiens.

Design:
Retrospective analysis.

Setting:
Departement of Obstetrics and Gynaecology, 1st Faculty of Medicine, Charles University and General Faculty Hospital, Prague.

Methods:
We retrospectively evaluated a group of 12 patients, that had undergone ultrasound examination during pregnancy at our department and afterwards had been diagnosed during caesarean section (CS) with placenta accreta (years 2010–2011).

Results:
11 out of 12 women in our group had at least one of the risk factors (placenta praevia, previous SC, history of uterine surgery). During US examination, suspicion of placenta accreta was raised at 7 out of 12 women.

In 5 cases we have performed elective CS and in 7 cases CS was done after onset of the labour (in 4 cases the reason was severe bleeding). The peripartal blood loss ranged from 500 ml to 7000 ml. Due to life threatening bleeding in 5 cases (42%), abdominal hysterectomy was performed. Placenta accreta was successfully diagnosed in cases with hysterectomy by US in 80 percent (4/5). Histological examination of the uterus confirmed in 2 cases placenta accreta, in 2 cases placenta increta and in 1 case placenta percreta.

Conclusion:
US diagnosis of placenta accreta is possible, with success rate of 58 percent (7/12). Early diagnosis helps to properly set up CS and consult the patient about the risk of unavoidable hysterectomy.

Key words:
diagnosis, placenta accreta, ultrasound.
