title: Computed tomographic pelvimetry in the evaluation of breech presentation.
abstract: 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.
