Contribution of Scanopelvimetry in the Prognosis of Childbirth

Abstract

ObjectivesTo determine the frequency of the demand of radiopelvimetry in pregnant women and to assess the obstetrical prognosis.MethodsRetrospective study about 19 months, including a total of 45 pregnant women who underwent scanopelvimetry to evaluate the biometry of the pelvis. Scanopelvimetry was performed from 36th week of pregnancy.ResultsThe average age of the patients was 26.9 years. The frequency of the demand of scanopelvimetry was 0.97%. The height of the patients was greater than 150 cm in 84.44%. The indications of radiopelvimetry were dominated by the clinical suspicion of pelvic narrowing (57.78%), followed by the cephalopelvic confrontation (33.33%) and the cicatricial uterus (8.89%). Narrowed pelvis was observed in 28.89% of cases (13/45), with a Magnin index of less than 21. A caesarean section during labor was performed in 24.44% of the cases. No death of newborn was reported.ConclusionThe frequency of the demand of scanopelvimetry is low but the rate of surgical pelvis is high among suspect cases.
