Cervical weakness is an important cause of late miscarriage and extreme preterm labour. Women have been traditionally offered a cervical cerclage procedure, though studies failed to demonstrate a therapeutic effect. None of these studies has addressed the effect of non-braided to braided suture material on cerclage outcome. Type of suture material is an important determinant of surgical outcomes. This issue is of particular relevance to cerclage because the traditionally braided suture has been associated with increased risk of infection in other surgical procedures. Indeed, infection is an important underlying cause for cerclage failure. It is for this reason that some surgeons use non-braided suture material. Therefore, we hypothesise that the unrealised benefit of cervical cerclage is at least in part due to the type of suture material used. In this article, we present the rationale behind our hypothesis and a proposed way of testing it.
