One month later same woman was admitted again to the Clinic due to bleeding and ultrasound finding suspicious to residual trophoblastic tissue. Beta human chorionic gonadotropin serum concentration at the day of admittance was 8,419 IU/ml. Ultrasound finding showed inhomogeneous supracervical formation with dimension 2,73x1,89 cm with increased vascularity and resistant index 0.36 and suspicious placenta increta. We made decision to surgery, and performed hysterectomy in view of heavy intraoperative haemorrhage. Woman was discharged at fifth day after surgery in good condition.
