Clinical safety and efficacy of high-intensity focused ultrasound（HIFU） in the treatment of placenta accreta

Abstract:

Objective：To evaluate the clinical safety and efficacy of high -intensity focused ultrasound（HIFU） in the treatment of pla－centa accreta． Methods：Fifteen patients with placenta accreta were treated with the HIFU. The blood-perfused area of placenta acc－reta was observed through sulphur hexafluoride microbubbles；the placenta accreta volume and the blood β-human chorionic go－nadotropin（HCG）as well as the time of return of normal menses were evaluated by color Doppler ultrasound. Results：After the treat－ment of HIFU，the blood-perfused area of fourteen cases was disappeared. One case still had blood perfusion，the effective rate of im－mediate treatment was 93.3% and the effective rate of one-week treatment was 100%. The bloodβ-HCG of fourteen cases were sig－nificantly reduced after treatment. In addition，nine cases resumed normal menstruation. Conclusion：HIFU as a new treatment method for placenta accreta is safe and effective．
