Breech presentation: increasing maternal choice

Pregnant women with a third trimester breech presentation are almost invariably offered Caesarean section as the mode of delivery of first choice, especially when external version has failed to turn the fetus to cephalic. However, increasingly women are resorting to alternatives, to avoid either operative delivery or manipulative intervention in late pregnancy. This paper reviews some of the options for women with breech presentation, focusing especially on integrating these options into conventional maternity care.

External cephalic version: a safe procedure? A systematic review of version-related risks

BACKGROUND

The Term Breech Trial has considerably increased the number of cesareans. External cephalic version (ECV) might be an effective method of lowering the rate of cesareans; its efficacy has been well established. However, although in the absence of anesthesia the risks are thought to be low, most studies have used populations too small to allow definite conclusions on version-related risks.

METHODS

In an attempt to make an inventory of these risks, we have systematically analyzed 44 studies, covering a total of 7377 patients from 1990 to 2002. The studies used were derived from a Medline and Embase search.

RESULTS

The most frequently reported complications were transient abnormal cardiotocography (CTG) patterns (5.7%). Persisting pathological CTG readings (0.37%) and vaginal bleeding occur rarely (0.47%). The incidence of placental abruption was even lower, at 0.12%. Fetomaternal transfusion was absent in five out of seven studies, with a mean incidence of 3.7%. Emergency cesareans were performed in 0.43% of all versions. Perinatal mortality was 0.16%.

CONCLUSIONS

External cephalic version seems to be a safe procedure.
