Objectives. To make a comparative assessment of the effectiveness and safety of the use for the correction of cervical insufficiency (CI) during pregnancy of the vaginal cerclage with polyester tape and suture material from 2 nylon threads.
Material and methods. This study included 28 pregnant women with CI who had undergone vaginal cerclage: in the 1st main group (12 patients) polyester tape was used, in the 2nd control group (16 patients) – suture material from 2 nylon threads. Pregnancy and childbirth outcomes were evaluated on the basis of clinical, laboratory, instrumental and statistical methods.
Results. Patients of groups I and II were comparable in age and parity. Preventive, planned and urgent vaginal cerclage was performed. Intraoperative bleeding and suture cutting were observed only in the control group: in 1 (7.1%) and 2 (14.3%) pregnant women; the frequency of abortion after cerclage in groups I and II was 2 (16.7%) and 3 (21.9%) (p=0.848) cases, respectively. The termination of pregnancy at 28-33 weeks of gestation occurred in 1 (8.3%) patient from group I and 3 (21.9%) from group II (p=0.706); at 34-36 weeks of gestation in 5 (41.7%) and 6 (42.9%) (p=0.737); at 37 and more weeks of gestation in 6 (50.0%) and 5 (35.7%) (p=0.737) patients, respectively. 7 (58.9%) children from group I and 7 (50.0%) from group II (p=0.976) were discharged from the maternity home.
Conclusions. The vaginal cerclage allows to prolong pregnancy up to a period of 34 weeks of gestation and more in 78.6% of cases, up to 37 weeks and more in 39.3% of cases; the use of polyester tape for the correction of CI showed comparable efficiency with that of nylon; the safety of the polyester tape use has been confirmed by the absence of cases of intraoperative bleeding, suture cutting, simplicity and convenience of cerclage applying.
Key words: cervical insufficiency, cerclage, polyester tape.
