Abstract

The size of an animal's pelvis can have a substantial impact on the ease or difficulty of giving birth, which can vary depending on the breed. Radiography is a medical imaging technique that is commonly utilized in clinical cases to assess pelvic dimensions. The present retrospective, observational study was designed to evaluate pelvimetric differences in radiographic images of British Shorthair (BS) cats with dystocia and eutocia. Pelvimetric values (linear distance, angle, area, height/width) for ventrodorsal and laterolateral radiographic images were recorded in 15 BS cats with dystocia and 15 BS cats with eutocia. Statistical analysis of the obtained measurement values was performed. When the pelvimetric data were examined overall, it was seen that mean values, except the PL (pelvis length) measurement, were higher in cats with eutocia than in cats with dystocia. Vertical diameter, conjugate vera, coxal tuberosities, transversal diameter, acetabula, pelvic inclination, ischiatic arch, pelvis inlet area (PIA), and pelvic outlet area (POA) values were significantly higher in cats with eutocia than in cats with dystocia (P < 0.05). Mean PIA and POA measurement values in cats with dystocia were 22.89 ± 2.38 cm2 and 19.59 ± 1.90 cm2, respectively; in cats with eutocia, the mean was calculated as 27.16 ± 2.76 cm2 and 23.18 ± 1.88 cm2, respectively. In conclusion, the present study revealed that pelvimetric values, except the PL measurement, were higher in cats with eutocia than in cats with dystocia. Findings can be used to assist veterinarians in future clinical decision-making for pregnant BS cats.
