Two had undergone an intervention to prevent SPB, cervical cerclage
of which one resulted in SPB.
A patient-level meta-analysis published in 2011 demonstrated that cervical cerclage
placement was associated with a significant reduction in preterm birth before 35 weeks' gestation in women with singleton gestations, previous spontaneous preterm birth, and cervical length less than 2.
The use of a cervical cerclage
and Foley's balloon tamponade in preventing haemorrhage in cervical ectopic pregnancies has been reported in three cases.
In addition to preventing recurrent uterine inversion, one potential benefit to the placement of the abdominal cervical cerclage
is possible prevention of future cervical incompetence related to the surgical division of the posterior cervical ring.
In singleton pregnancies in women with previous preterm births the rate of recurrence is reduced by about 25% either by the prophylactic administration of progesterone or by cervical cerclage
involves the placement of sutures, wires, or synthetic tape to mechanically increase the tensile strength of the cervix.
Therefore, some obstetricians/gynecologists decide to perform cervical cerclage
to prevent preterm delivery, but it was rejected due to the increasing chanc of infection that might trigger preterm delivery by itself (2).
Success rates after cervical cerclage
are high, up to 87%.
However, cervical cerclage
and induction of labor appeared to be risk factors for cervical laceration in these deliveries, wrote Dr.
It is important to realize that rupture of membranes after a cervical cerclage
may be the result of a sub-clinical infectious process, rather than the consequence of cerclage placement.
Cerclage is indicated for cervical incompetence, which is defined by the need for a cervical cerclage
," he said at a meeting on antepartum and intrapartum management sponsored by the University of California, San Francisco.
Four women were given cervical cerclage
during pregnancy said Dr.
