A systematic study was performed in 31 pig spleens to provide an analysis of the splenic arterial segmentation and an analysis of the proportional area of each segment. There were two independent arterial segments in all cases, a dorsal and a ventral. The dorsal segment was smaller than the ventral segment, presenting 16.81 and 83.19% as the median percentage of the total area of the spleen, respectively. In conclusion, the pig arterial segments are quite similar to those of dog, buffalo, goat, and sheep, where there is a small dorsal segment and a large ventral segment, and somewhat similar to the human spleen, where there are two segments as well, though with a similar area.
