The sonographic features of chorionic bump ,such as the size and number were analyzed . Results There were 55 cases of miscarriage in 137 cases ,the rate happened in early pregnancy was 40 .1％ . The rate of miscarriage between the chorionic bump group and the control group had statistical difference( P =0 .000) . The chorionic bump group was divided into two subgroups according to the different number of chorionic bump ,single and multiple bumps , the rates of abortion were 35 .2％ and 80％ ,respectively .
