Cesarean scar ectopic pregnancy
Updates to Study Attributes
A transvaginal ultrasound examination shows a retroverted uterus with the presence of a gestational sac positioned on the anterior part of the lower uterine section, corresponding to the prior caesarean scar region. The myometrial thickness measures 0.24 cm, meeting the criteria of a caesarian scar ectopic pregnancy 1.
The uterine cavity and the cervical canal were empty. The cervical canal is filled with a thin streak of fluid extending into the scar region.
