Abstract

Abstract: The application value of transabdominal ultrasound (TAUS) combined with human chorionic gonadotropin (HCG) and alpha fetoprotein (AFP) in the diagnosis of pernicious placenta previa (PPP) with placenta accreta (PA) is analyzed in this study. 73 patients with PPP were divided into placental implantation group (31 cases) and non placental implantation group (42 cases), while 35 cases healthy pregnant women as control group. The levels of HCG and AFP and TAUS were examined before delivery. The results showed that the levels of HCG and AFP in placental implantation group were higher than those of non placental implantation group and control group (P<0.05). The AUC, sensitivity and specificity of TAUS combined with HCG and AFP in the diagnosis of PPP with PA were 0.912, 96.8% and 85.7%, respectively, which were higher than those of single test (P<0.05). Therefore, it has a certain value of HCG and AFP in the diagnosis of PPP with PA, and combination with TAUS can improve the diagnosis efficiency.

Key words: pernicious placenta previa, placenta accreta, transabdominal ultrasound, human chorionic gonadotropin, alpha fetoprotein
