Abstract

Abstract: The value of transabdominal combined transvaginal color Doppler ultrasonography in evaluating the pernicious placenta previa (PPP) complicated placenta implantation was analyzed in this study. 172 patients with PPP from June 2017 to June 2019 were selected as the subjects of this study, all patients were examined by transabdominal and transvaginal color Doppler ultrasonography. The evaluation value of transabdominal and transvaginal color Doppler ultrasonography and their combination to PPP complicated placenta implantation was analyzed. The postpartum pathological results showed that among 172 patients with PPP, 120 patients (69.77%) were complicated placenta implantation, and 52 patients (30.23%) were not omplicated placenta implantation. In the sensitivity, specificity and accuracy of evaluating the PPP complicated placenta implantation, the transabdominal color Doppler ultrasonography were 76.67%, 73.08% and 75.58%, the transvaginal color Doppler ultrasonography were 83.33%, 80.77% and 82.56%, the transabdominal combined transvaginal color Doppler ultrasonography were 96.67%, 96.15% and 96.51%, the transabdominal combined transvaginal color Doppler ultrasonography were significantly higher than the transabdominal and transvaginal color Doppler ultrasonography, the difference was statistically significant (P<0.05). This study confirms that, Transabdominal and transvaginal color Doppler ultrasonography are the effective methods for evaluating the PPP complicated placenta implantation, and their combined evaluation value is higher, it's worth for further clinical promotion.

Key words: transabdominal, transvaginal, color Doppler ultrasonography, evaluate, pernicious placenta previa(PPP), placenta implantation
