Pelvimetry is a diagnostic procedure that involves measuring the dimensions of the pelvis, with or without the localization of the placenta. This assessment is particularly relevant in the context of pregnancy, as it helps to evaluate the potential for a successful vaginal delivery. The primary concern addressed by pelvimetry is cephalopelvic disproportion (CPD), a condition where the size of the fetal head is too large in relation to the dimensions of the mother's pelvis, potentially complicating the delivery process. Historically, pelvimetry was a routine procedure performed on pregnant women to assess their ability to deliver, especially in cases where the fetus is in a breech position. However, its use has diminished in contemporary practice. During the procedure, the patient is typically positioned standing, allowing for a lateral view of the pelvis and the pregnant uterus to be captured. Additional sagittal views may also be obtained to provide further insight. The physician conducts precise measurements of the pelvic inlet and outlet, which are then compared to the measurements of the fetal head. In instances where the fetus is in a breech position, the physician specifically evaluates the pelvic dimensions to ascertain whether a safe attempt at a breech delivery is feasible. Furthermore, the procedure may also involve determining the location of the placenta, which can be critical for planning the delivery approach.
