“…This is not consistent with previous studies, in which pelvimetry was found to be useful only in the case of breech presentation [27,28,29]. Pelvic scanning should be limited to breech presentations, because it increases the likelihood of caesarean section in cephalic presentations [5].…”

Objective: To assess the variables useful to predict caesarean delivery (CD) and instrumental assistance, through the analysis of a large number of foetal-pelvic variables, using discriminant analysis. Materials and Methods: One hundred and fourteen pregnant women were included in this single-centre prospective study. For each mother-foetus pair, 43 pelvic and 18 foetal variables were measured. Partial least squares-discriminant analysis was performed to identify foetal-pelvic variables that could statistically separate the 3 delivery modality groups: spontaneous vaginal delivery (SVD), CD, and instrument-assisted delivery (IAD). Results: For the SVD versus CD model, voluminous foetuses and women with a narrow pelvic inlet had a greater risk for requiring CD. The most efficient variables for discrimination were the transverse diameter and foetal weight. The antero-posterior inlet and obstetric conjugate were considered in this model, with the former being a useful variable but not the latter. For the SVD versus IAD model, the most important variables were the foetal variables, particularly the bi-parietal diameter. Women with a reduced antero-posterior outlet diameter and a narrow pubic arch were more at risk of requiring an IAD. Conclusion: The antero-posterior inlet was an efficient variable unlike the obstetric conjugate. The obstetric conjugate diameter should no longer be considered a useful variable in estimating the arrest of labour. Antero-posterior inlet diameter was a sagittal variable that should be taken into account. The comparison of sub-pubic angle and bi-parietal and antero-posterior outlet diameters was useful in identifying a risk of requiring instrumental assistance.

“…In our study, the Magnin index was less than 21 in 28.89%, between 21 and 23 in 26.67% and greater than 23 in 44.44% whereas a French study found 55.5% of unfavorable prognosis according to the Magnin index (<23 cm) [ 11 ]. However, our result is close to that of Christian et al, who found 33.33% of narrowed pelvis [ 12 ] but widely different than that obtained by Adjenou et al.…”

“…Among the caesarized patients, 54.17% had a Magnin index of less than 21 and 37.5% had between 21 and 23. No patient gives birth by vaginal delivery with a Magnin index below 21, as in the study of Frémondière and Fournie [ 11 ], which would authenticate the importance of this index in the prognosis of childbirth.…”

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.

“…In a previous study, the reliability of the fetal-pelvic index was confirmed as having high sensitivity and specificity ratios for determining the mode of delivery [ 23 ]. In some hospitals, CPD can be conflated with dystocia related to uterine activity, thus complicating the determination of the prevalence of true CPD [ 24 ].…”

Objectives: To determine the incidence of gynecoid pelvis by using classical criteria and measured parameters obtained from three-dimensional computed tomography (3D CT) pelvimetry in nonpregnant multiparous women who delivered vaginally. Subjects and Methods: Our hospital's picture archiving and communication system was reviewed retrospectively. All adult women who had undergone CT examination with routine abdominal protocols were identified. In the pelvic inlet, midpelvis, and pelvic outlet, classical criteria and measured parameters, both alone and in combination, were used to determine the presence of gynecoid pelvis. Results: 3D CT pelvimetry was performed on 226 women aged 23-65 years without any history of cephalopelvic disproportion and who had at least one delivery of an average fetal size (>2,500 g). The median parity was 4, and the mean (±SD) birth weight was 3,700 ± 498 g. Compared to the classical criteria, measured parameters and their combined use with the classical criteria significantly reduced the frequency of gynecoid pelvis (51.3 and 47.8%, respectively, vs. 71.6%; p = 0.001); however, there was no significant difference between the measured parameters and their combined use with classical criteria with regard to the frequencies of gynecoid pelvis (p > 0.05). Conclusions: With the use of measured parameters of 3D CT pelvimetry, the incidence of gynecoid pelvis reduces to a more acceptable level (51.3%) in accordance with obstetric knowledge. Since there is no considerable decrease with the addition of classical criteria, 3D CT pelvimetry alone has merit for determining a woman's pelvic capacity for obstetric needs after the improvement and standardization of measured parameters.
