ARAÚJO, Glauce Vaz Diniz. One-dimensional analysis of the lateral ventricles and third ventricle of poodle dogs through computed tomography. 2018. 48p Dissertation (Master's Degree in Veterinary Medicine, Pathology and Clinical Sciences). Institute of Veterinary Medicine, Department of Animal and Human Anatomy, Federal Rural University of Rio de Janeiro, Seropédica, RJ, 2018.

The study of the Nervous System of domestic animals, in vivo, it’s growing in Veterinary Medicine as new diagnostic techniques such as Computed Tomography (CT) become a reality. However, despite such available technology, standardized values of the ventricular system in the different skull morphotypes and breeds of dogs are still scarce in the literature regarding tomographic evaluation. In view of these facts, the present study had as objective the quantitative and qualitative morphometric evaluation of the lateral ventricles and the third ventricle of 55 Poodle dogs, without encephalic alteration, of both genders and in several age groups. A retrospective study of tomographic images, acquired in the period from March 2012 to March 2017, was carried out at the Radio Vet diagnostic imaging center, located in the city of Rio de Janeiro. The purpose of the study was to contribute to the standardization of linear measures of height and width of the lateral ventricles and third ventricle, as well as to provide values of proportion between the ventricular system and the encephalon, as well as the correlation between the heights of the brain and skull with the height of the lateral ventricles. In the qualitative analysis, the objective was to evaluate the existence of subjective ventricular asymmetry in dogs without encephalic alteration, of the aforementioned race. As a result, it can be concluded that there was no statistical difference between the right and left antimeres when compared to the mean height and width of the lateral ventricles in all study groups. The mean right ventricular height in the M1 group was 5,18 mm ± 0,70, 6,06 mm ± 1,53 in the M2, 6,20 mm ± 1,77 in the F1, and 6,47 mm ± 1,45 in F2. The mean left ventricular height in the M1 group was 4,74 mm ± 1,29, in the M2 it was 6,05 mm ± 1,30, in the F1 it was 5,37 mm ± 1,96 and in the F2 it was 6,03 mm ± 1,77. Regarding the ventricular width, the mean for the right ventricle in the M1 group was 6,24 mm ± 1,59, in the M2 it was 7 mm ± 1,28, in the F1 it was 6,47 mm ± 1,45 and in the F2 it was 7,18 mm ± 1,33. The mean left ventricular width in the M1 group was 6,12 mm ± 1,36, in the M2 it was 7,37 mm ± 1,03, in the F1 it was 6,9 mm ± 1,15 and in the F2 it was 7,15 mm ± 1,47. The third ventricle presented as mean height in the M1 group 3,13 mm ± 0,63, in the M2 3,33 mm ± 0,91, in the F1 3,7 mm ± 0,29 and in the F2 3,56 mm ± 0,54. Regarding the mean width of the third ventricle in the M1 group was 2,4 mm ± 0,56, in the M2 was 2,94 mm ± 0,84, in the F1 was 3,01 mm ± 0,35 and in the F2 was 2,08 mm ± 0,8. Ventricular asymmetry was observed in 14.54% of the animals evaluated, and more frequently the right ventricle was larger.
