Transabdominal Cerclage.

The transabdominal cerclage procedure was first introduced 50 years ago as an approach in those patients who had failed transvaginal cerclage. We review the history, indications, surgical technique, complications, and reported outcomes of the procedure. The procedure has evolved over time in its application and risks appear to be less than previously perceived. Physicians have found additional patient situations in which the procedure may be beneficial outside the indications defined 50 years ago. This is a valuable surgical technique which is likely underused.
