The study was carried out from April 2014 to December 2015, during which 70 patients with complete previa and 113 with incomplete previa between 20+0 weeks and 25+6 weeks of gestation were included. Maternal demographics and pregnancy outcomes were compared between the two groups. Comparisons between categorical variables were tested by chi-squared test and those between continuous variables by Student t test. Resolution ofprevia occurred in 87.43% of the studied women. The mean gestational age at resolution was 32.1+4.4 weeks. Incidence of maternal age ≥35 years and incidence of prior uterine operation 〉3 were high in women with complete previa (28.6% vs. 8.8%, P=0.003; 28.6% vs. 8.8%, P=0.003). Resolution ofprevia occurred less often in complete previa group (74.3% vs. 95.6%, P=0.001). Women with complete previa admitted earlier (37.3±2.0 weeks vs. 38.1±1.4 weeks, P=0.011) and delivered earlier (37.7±1.2 weeks vs. 38.3±1.4 weeks, P=0.025). Maternal age ≥35 years and prior uterine operation 〉3 increase the risk of complete previa in mid-pregnancy. Placenta previa is more likely to persist in women with complete previa than those with incomplete previa diagnosed in mid- pregnancy. What is more, women with complete previa in mid-pregnancy delivers earlier.展开更多
