A Report of Four Cases of Caesarean Scar Pregnancy in a Period of 24 Months

Case 1: A 35 -year-old woman, G3P2, presented in early pregnancy with light vaginal bleeding that had begun earlier in the day. Her obstetrics history revealed 2 lower transverse caesarean sections performed 3 and 4 years previously. Her last menstrual period placed her gestational age at 9 weeks, and she had not yet begun prenatal care. The first transvaginal sonographic evaluation revealed a gestational sac with two viable embryos low in the uterine cavity. The crown-rump lengths were 14, 14.5 mm corresponding to a gestational age of 7 weeks and 6 days. A repeat transvaginal ultrasound scan (by an experienced sonographer) 15 days after the initial examination revealed twin pregnancy of 10 weeks with cardiac activity low in the uterine cavity.
