Amnioreduction in patients with bulging prolapsed membranes out of the cervix and vaginal orifice in cervical cerclage
Objective: To determine whether an amnioreduction via
bulging membranes (AVBM) and cerclage could be useful
in 17 women with singleton gestations demonstrating
hourglass membranes bulging out of the cervix or vaginal
orifice.
Methods: We used the following selection criteria for
AVBM under ultrasonographic guidance using a peit needle
because of undetectable cervical edges: (type 1) the
bag of membranes protruded beyond the inlet of the
vagina; (type 2) the bag of huge membranes completely
occupied the vagina.
Results: Eight patients (three cases of type 1 and five of
type 2) were successful in AVBM and cerclage at
22.1±2.2 weeks gestation (range 19–24 weeks), and
mean birth weight was 1,048.1±801.6 g (range 302–
2,688 g). Although the diameter of the forewater by
transabdominal ultrasonography (cm) was higher than
in the nine patients without AVBM (6.7±1.1 versus
4.1±0.7 cm, p=0.002), the prolongation of pregnancy
(32.9±46.2 days; range 2–133 days) was the same as in
patients without AVBM (36.9±39.3 day, p=1.000).
Conclusion: It is important that every effort should be
made to perform cervical cerclage at or before 26 weeks
of gestation, even in women with type 1 or 2.
