There are different techniques for performing the cerclage. The two most common are the McDonald and Shirodkar.
The McDonald procedure is done with a 5 mm band of permanent suture is placed high on the cervix. This is indicated when there is significant effacement of the lower portion of the cervix. It is generally removed at 37 weeks, unless there is a reason to remove it earlier, like infection, preterm labor, premature rupture of the membranes, etc. It is also shown that this has very little impact of the chance for vaginal delivery. The Shirodkar is also used a frequently used technique. However, this was previously a permanent purse string suture that would remain intact for life. When this type of cerclage is done, a cesarean section will always be performed. There are physicians performing modified techniques, where the delivery does not necessarily have to be by cesarean, nor the suture left intact. Ask your practitioner which procedure they perform.
