Three-dimensional computed tomographic examination of pelvic cavity in Van Cats and its morphometric investigation

This study was carried out to determine the morphometric values of the pelvic cavity, the cranial and caudal pelvic aperture by three-dimensional (3D) reconstruction of the images obtained by computed tomography in adult Van Cats and to show the differences between these indicators in both genders. A total of 16 adult Van Cats, eight male and eight female, were used in the study. Animals were anesthetized with ketamine–xylazine combination and were scanned by computerized tomography. Images of the pelvic cavity were obtained. Three-dimensional reconstruction of the pelvis was performed with three-dimensional modelling program. Measurements of the diameters of the pelvic cavity, the cranial and caudal pelvic aperture were calculated from these images, and statistical analyzes were performed. Three-dimensional modelling of the pelvic cavity of Van Cats were examined between males and females. The results showed that there were significant (p < .05) differences between measurement of the pelvic inclination, the medial transverse diameter, the caudal transverse diameter and the angle between ischiatic arch. In addition, the correlations between age and weight were found statistically significant (p < .05) with the dorsal transverse diameter, the intermediate transverse diameter and the caudal transverse diameter in males. On the other hand, the correlations of age were statistically significant (p < .01) with the cranial pelvic aperture and the caudal pelvic aperture in females. In conclusion, some biometric values of pelvic cavity were observed to be statistically different in Van Cats.
