Abstract
Objective To explore the values of transabdominal sonography (TAS) and transperineal sonography (TPS) in the diagnosis of pemicious placenta previa complicating placenta implantation.Methods 73 patients treated at our hospital from January,2015 to May,2017 were selected and were examined by TAS and TPS prenatally.The results were compared with the surgical and pathological results.The prenatal diagnostic values of TAS and TPS were evaluated.Results Among the 73 patients,postpartum surgical pathology confirmed that 60 cases (82.19％) had pernicious placenta previa complicating placenta implantation and 13 (17.81％) had only pernicious placenta previa.The prenatal diagnostic accuracy,sensitivity,and specificity by TAS were 69.86％,68.33％,and 76.92％ and those by TPS were 94.52％,96.67％,and 84.62％,respectively.The AUC value by TAS was of were no merge placenta implantation.The antenatal TAS diagnosed PPP merge placenta implantation of accuracy was 0.786 and that by TPS 0.957,with a statistical difference (Z=3.786,P=0.000).Conclusions Ultrasound in the prenatal diagnosis of pernicious placenta previa complicating placenta implantation has high value and TPS can markedly increase the diagnostuc accuracy,sensitivity,and specificity and decrease misdiagnosis and the missed diagnosis rates.关键词
