cervical incompetence
Inability of the cervix to remain closed during pregnancy, leading to premature cervical dilation.
Full Definition
Cervical incompetence, also known as cervical insufficiency, refers to the structural weakness of the cervix that results in painless cervical dilation and effacement during the second trimester of pregnancy. This condition can lead to pregnancy loss or preterm delivery if left untreated. Diagnosis is often made based on history of previous second-trimester losses and ultrasound findings of cervical shortening. Treatment typically involves cervical cerclage placement.
Usage
Usage note: Cervical insufficiency is the preferred modern terminology; avoid using incompetence in patient-facing materials.
