Abstract

FOZ FILHO, Roberto P.P.; MARTIN, Benedito W. de; LIMA, Ana Rita de  and  MIGLINO, Maria Angélica. Horse spleen segmentation technique as large animal model of preclinical trials. An. Acad. Bras. Ciênc. [online]. 2013, vol.85, n.4, pp.1411-1417.  Epub Oct 22, 2013. ISSN 0001-3765.  http://dx.doi.org/10.1590/0001-37652013110812.

The parenchymal distribution of the splenic artery was studied in order to obtain anatomical basis for partial splenectomy. Thirty two spleens were studied, 26 spleens of healthy horses weighing 320 to 450kg, aged 3 to 12 years and 6 spleens of fetus removed from slaughterhouse. The spleens were submitted to arteriography and scintigraphy in order to have their vascular pattern examined and compared to the external aspect of the organ aiming establish anatomo-surgical segments. All radiographs were photographed with a digital camera and the digital images were submitted to a measuring system for comparative analysis of areas of dorsal and ventral anatomo-surgical segments. Anatomical investigations into the angioarchitecture of the equine spleen showed a paucivascular area, which coincides with a thinner external area, allowing the organ to be divided in two anatomo-surgical segments of approximately 50% of the organ each.

Keywords : arteriography; equine; scintigraphy; spleen; splenic artery.
