Techniques for anatomical preparation of dried viscera and angioarchitecture of cranial mesenteric artery branching of dogs and cats / Técnicas anatômicas de preparação de vísceras secas e de angioarquitetura para visualização da ramificação da artéria mesentérica cranial em cães e gatos

ABSTRACT

Background: The study of the arterial vascularization of the abdominal cavity viscera is essential on the process of learning anatomy. For authors, various anatomical techniques can be used for the preservation of structures, allowing the exploration and visualization of the organs shape in many different ways. Among the techniques there is the angioarchitecture of viscera, with or without the utilization of formaldehyde. The aim of this paper is to describe a technique for anatomical preparation of the intestines (small and large) of dogs and cats using dried viscera and angioarchitecture, to facilitate the study and visualization of the cranial and caudal mesenteric arteries branching.Materials, Methods & Results: Twenty pieces of intestine of dogs and two of cats were used. The intestine was removed from the duodenum to the cranial portion of the rectum, the root of the mesentery was sectioned as well as the cranial and caudal mesenteric arteries. The part was washed, then the caudal and cranial mesenteric and pancreaticoduodenal arteries were ligated, latex was injected in the cranial mesenteric artery and the sample remained immersed in a 10% acetic acid aqueous solution. The cranial portion of the rectum was ligated and, through a cannula into the duodenum, air was insufflated until the viscera were distended. Following that, the part was positioned and fixed, exposed...(AU)
