The Shirodkar operation: a reappraisal.
Sixty-six cerclages were performed by one surgeon in 46 patients with documented cervical incompetence. The mean operative blood loss was 25 ml, and the mean operating time was 18 minutes with no postoperative morbidity. Fifty-five of the pregnancies were carried for at least 37 weeks, eight were delivered before 37 weeks, and three are continuing. Six of the eight preterm deliveries were a result of factors unrelated to cervical incompetence. The two remaining preterm births were probably also unrelated because one occurred 8 days after emergent cerclage placement and the other occurred 12 weeks after the procedure, both as a result of premature rupture of membranes. There were no cesarean deliveries related to the Shirodkar suture. The efficacy of the procedure was demonstrated by a corrected perinatal survival rate of 100% and term delivery of 88%. (Since this article was written all three of the undelivered patients were delivered of infants after 37 weeks' gestation for a term delivery rate of 88% with 100% neonatal survival.
