What is Incompetent placenta?

Incompetent placenta, often referred to as cervical incompetence or cervical insufficiency, is a condition where the cervix begins to dilate and open prematurely during pregnancy, typically without significant uterine contractions. This can lead to preterm birth or miscarriage, particularly in the second trimester. The condition may be caused by various factors, including structural abnormalities of the cervix or previous cervical surgeries. Management often involves monitoring and potential interventions such as cervical cerclage to help support the pregnancy.
