  • Comment by the editor:  Trachelorrhaphy after failed cerclage
    Cervical insufficiency has a high risk of recurrence and is traditionally treated with transvaginal cervical cerclage.  If this fails, one option is abdominal cervical cerclage, but another, less widely used, option is transvaginal trachelorrhaphy – reconstruction of the internal cervical os.   In this series of 16 patients treated by trachelorrhaphy (and first-trimester cerclage) there were 9 term deliveries, 7 preterm deliveries and an 84% fetal survival rate. The authors recommend trachelorrhaphy as safe, reproducible and easy to learn.

  • Comment by the editor:  Renal transplantation and other risk factors
    Most pregnancies in renal transplant recipients are successful but there is a high risk of complications like pre-eclampsia, low birth weight and premature birth.  The reasons for this extend beyond the transplant itself.  This report from a tertiary centre found that 77% of patients pregnant after renal transplantation had a broad range of additional risk factors, ranging from urinary leakage to previous heart transplantation.  Even so, multidisciplinary care can still achieve successful outcomes in these ultra-high-risk pregnancies.

  • Comment by the editor:  LLETZ and preterm delivery
    Removal of cervical tissue increases the risk of preterm birth, but studies differ on whether the risk varies with the depth of tissue removed at large loop excision of the transformation zone (LLETZ).   In this study, women who had undergone LLETZ were matched with controls who had had cervical punch biopsies.  The LLETZ group had a threefold higher risk of preterm birth but the risk was not related to the volume of tissue removed.  This will reassure clinicians that LLETZ should still be performed with adequate tissue margins.
