Abstract

Objectives: The purpose of this study was to review the indications of transabdominal cervicoisthmic cerclage and clinical outcome to determine whether it is a valid alternative to transvaginal cerclage.
Method: A retrospective review was carried out of transabdominal cerclage patients at our hospital from Jan. 1999 to Dec. 2004. Analysis of the indications for the transabdominal rather than the vaginal approach and evaluation of fetal outcomes was performed.
Results: 48 patients underwent transabdominal cerclage. The primary indication for transabdominal cervicoisthmic cerclage was failed transvaginal cerclage in 23 patients, the secondary indication was short cervix for transvaginal cerclage in 19 patients and cervical laceration in 6 patients. In 48 pregnancies, 8 twins were included. Therefore, total number of fetus was 56. One fetus of twin died in uterus at 27 weeks of gestation with unknown cause. 48 patients successfully delivered 55 live babies by Cesarean section. However, three babies died due to Tetralogy of Fallot, gastroschisis and preterm delivery. Complication including blood loss requiring transfusion did not occur. All patients had histories compatible with incompetent cervix requiring cerclage, and none were suitable candidates for vaginal cerclage. Live birth rate was 92% (52/56), compared with 28% salvage of pregnancies beyond the first trimester before the transabdominal cervicoisthmic cerclage procedure.
Conclusion: Our results and review of literature confirm that with strict indications transabdominal cervicoisthmic cerclage offers a high rate of fetal salvage with minimum of complications in patients with extremely poor obstetric histories because of cervical incompetence.
