Computed tomographic pelvimetry in the evaluation of breech presentation
The purpose of this investigation was to assess computed tomographic (CT) pelvimetry in the evaluation of breech presentation for trial of labor. Thirty-two patients with singleton term breech deliveries formed the study group. Seventeen of the 32 (53.1%) patients fulfilled the criteria for attempted vaginal delivery. Fourteen of the 17 (82.4%) delivered vaginally. All infants so delivered had five-minute Apgar scores greater than or equal to 7. Three of the 17 patients required abdominal delivery: one for fetal distress and two for arrest of dilation. These results compare favorably with studies using conventional x-ray pelvimetry. The advantages of CT over conventional pelvimetry include ease of performance, ease of interpretation, and decreased radiation dose to the fetus.
