Features of the course and branching of the cranial mesenteric artery of a domestic cat.

Abstract

In practice, veterinarians often encounter intestinal obstruction in small pets caused by ingestion of foreign objects. As a rule, it is accompanied by infringement of the obstructing body, which leads to a violation of the trophic part of the intestine and to its subsequent necrosis. Assessment of the possible consequences of this pathological process, as well as conducting competent surgical intervention to eliminate it, is extremely difficult without clear knowledge about the blood supply to the intestine. The purpose of the study is to establish the features of the course and branching of the cranial mesenteric artery in a domestic cat. The corpses of ten cats aged eight to twelve years, excluding Maine Coon cats, served as the material for its conduct. During the study, the method of vasorentgenography was used. The injection of the vascular bed was carried out through the abdominal aorta according to the generally accepted method. The injection mass was made according to the recipe: 1 part lead meerkat, 8 parts turpentine, 2 parts glycerin. After coagulation of the injection mass by performing a fine anatomical dissection, the intestines were removed from the corpse together with the mesentery supporting it. X-ray shooting of the obtained preparations was carried out under the following technical conditions: current - 50 mA; tube voltage - 35 kV; focal length up to 50-60 cm; exposure - up to 1.5-3.0 seconds. Digital processing of the obtained images in order to determine morphometric parameters was carried out using the RadiAnt DICOM Viewer software. It has been established that the cranial mesenteric artery in a domestic cat participates in the blood supply of the pancreas and most of the intestine, excluding the initial section of the duodenum, the distal part of the colon and the rectum. Branches extending from it richly anastomose with each other, forming many ways of collateral blood flow.
