[edit] Discussion of Cervical incompetence

  • Cervical incompetence is a common cause of pregnancy failure in the second trimester
  • Manifests as painless dilatation of the cervix that leads to preterm labor.
  • Cervical incompetence may present with premature rupture of membranes, resulting in oligohydramnios.

[edit] Imaging Findings for Cervical incompetence

  • Sonographic findings include bulging of the fetal membranes into a widened internal os and shortening of the cervical canal.
  • The cervical length is obtained by measuring the endocervical canal from the internal cervical os to the external cervical os.
  • Endovaginal sonography is the more accurate method.
  • The mean cervical length is normally greater than 3 cm.
  • The sonographic determination of the residual closed length of the cervix may be used as a prognostic indicator for the risk of preterm labor progressing into preterm delivery.
