Diagnosis of Cervical Insufficiency
Transvaginal ultrasonography at ≥ 15 to 16 weeks for women with symptoms or risk factors Usually, cervical insufficiency is not identified until after the patient has had at least one delivery after 15 weeks ( Diagnosis reference ). The diagnosis of cervical insufficiency is suspected in patients with risk factors or characteristic symptoms or signs. If there is uncertainty about the clinical suspicion of cervical insufficiency, patients may be monitored starting at 15 to 16 weeks through 23 to 24 weeks with serial transvaginal ultrasonography to measure cervical length.
