A 26-year-old woman, gravida 3, para 0, at 18 weeks' gestation comes to the emergency department because of a large amount of vaginal discharge 30 minutes ago. She was sitting on her couch when the clear fluid began to rush out of her vagina. It did not have an odor. She reports feeling well lately, has had no sick contacts, and has not been sexually active. Her medical history includes two previous miscarriages in the second trimester. Her temperature is 37.0°C (98.6°F), pulse is 84/min, respirations are 16/min, and blood pressure is 132/84 mm Hg. She is not experiencing any pain. Pelvic examination shows a 3cm cervical dilation with 50% effacement. She goes into labor and delivers the previable infant within 2 hours. Three months later, a transvaginal ultrasound shows a short cervical length. Which of the following is the most likely diagnosis?

Memory Anchors and Partner Content
Cervical insufficiency (previously known as cervical incompetence) is a medical condition in which a pregnant woman's cervix begins to dilate (widen) and efface (thin) before her pregnancy has reached term. Definitions of cervical incompetence vary, but one that is frequently used is the inability of the uterine cervix to retain a pregnancy in the absence of the signs and symptoms of clinical contractions, or labor, or both in the second trimester. Cervical incompetence may cause miscarriage or preterm birth during the second and third trimesters. Another sign of cervical incompetence is funneling at the internal orifice of the uterus, which is a dilation of the cervical canal at this location.
