title: Cervical incompetence. A review.
abstract: Cervical incompetence is one of the main contributors to repeated pregnancy loss, accounting for approximately 25% of the cases. Typically it results in progressive cervical dilatation, leading to a painless second- or early-third-trimester abortion. In most instances cervical incompetence is the result of previous obstetric or gynecologic trauma; a congenital etiology is unusual. Despite the various reported diagnostic procedures, the obstetric history and frequent visual and digital examinations during pregnancy remain the most important factors in arriving at the correct diagnosis. In spite of the fact that numerous procedures have been advocated as treatment, the McDonald purse string closure technique is by far the most simple and effective corrective surgical technique, yielding an overwhelming number of successful pregnancies.
