E-mail: The knowledge of anatomical variations is important for radiological and surgical procedures and has a theoretical and practical significance for experimental research and surgical practice in domestic animals. The aim of this study was to describe the main branches of lienal artery in domestic cats. The anatomical dissections were performed on 30 cadavers of adult cats, 15 male and 15 female, with a rostrum-sacral length of 47.9 cm and 46.6 cm respectively. Cats were positioned in right lateral decubit and a thoracic incision was made to remove the 6th and 7th ribs to cannulate the thoracic portion of aorta. After fixed with 10% formaldehyde solution and performing the injections with latex solution stained with pigment, the animals were dissected to identify the main branches of the lienal arteries. The average length and standard deviation of the lienal were calculated and compared in both sexes by unpaired t test. To verify if the frequency distributions observed for the 30 examined animals is in accordance with the literature, we performed the Quisquare (X2 )test, with a 5% level of significance, to test if the nullity hypothesis is true for the number of lienal artery main ramifications. The relations between the lienal artery length with rostrum-sacral length were calculated by the correlation coefficient “r” varying between -1 and +1, that is, -1 ≤ r ≤+1. The mean and standard deviation of the lienal artery was 1.28 cm ± 0.43 in females and 0.98 cm ± 0.54 in males. In all (100%) dissected cats the lienal artery, originated directly from the celiac artery as an only one artery giving different numbers of branches to the spleen, stomach greater curvature and left pancreatic lobe. No correlation was observed between the lienal arteries with the rostrum-sacral length in both sexes. The average length and number of lienal artery branches is not gender dependent.
