Abstract Introduction: The Barbados Black Belly is a breed of domestic sheep in the Caribbean island of Trinidad. Anatomical studies on the cranial and caudal mesenteric arteries are necessary to know the pattern of its blood supply to gain information in benefit of experimental surgery. Materials and Methods: The thoracic part of the aorta of five sheep was injected with red latex. Careful gross dissection of the cranial and caudal mesenteric arteries was performed either after embedding in 10% formalin solution for 2-3 days. Results: The cranial mesenteric artery originated from the abdominal aorta, caudally to the celiac trunk, giving caudal duodenal artery, jejunal arteries, ileal arteries, ileocolic artery and middle colic artery. The caudal mesenteric artery arises from the aorta, cranially to the external iliac arteries, originating the left colic and cranial rectal arteries. Conclusion: cranial and caudal mesenteric arteries supplied the small and large intestine of the Barbados Black Belly sheep except caudal part of the large intestine which were supplied by the middle and caudal rectal arteries.

The aim of this study was to reveal the blood supply of the intestinal tract in male adult turkey. Five healthy birds were collected from local suppliers at Baaqoba province. All birds were euthanized and their coelomic cavity was dissected. The descending aorta was cannulated and injected with colored latex, and then the course of arteries along the intestinal tract investigated. Small intestine received the blood by celiac artery, cranial and caudal mesenteric artery. Celiac was split into two branches right and left, the right branch of celiac artery supplied the proventriculus, gizzard, duodenum, pancreas, jejunum and distal part of ileum and cecum while left branch supply the stomach. The crania mesenteric artery nourished the terminal parts of duodenum, jejunum ileum and cranial part of the two ceca, on the other hand. Caudal mesenteric artery was the third artery that supplied the intestine which was short branch originated from descending aorta and divided into two groups cranial groups supplied distal part of ileum and base of ceca while the caudal groups supplied the rectum and cloaca and anastomosed with cranial mesenteric artery. Form the above results, it was concluded that the small and large intestine are nourished by the three major arteries namely Celiac, Cranial and Caudal mesenteric arteries and its branches.

Common celiacomesenteric trunk, with the celiac and superior mesenteric arteries having a common origin from the aorta, is the least frequently reported anatomic variation of all abdominal vascular anomalies. Knowledge of variations concerning the celiac trunk and superior mesenteric artery are of great importance for both surgical approaches and angiographic examinations. Clinicians should keep in mind these variations to avoid complications.

We present the case of a 45-year-old male patient with a large aneurysm of the inferior mesenteric artery complicated by mid aortic syndrome with occlusion of the celiac trunk and superior mesenteric artery. The vascular pathology was detected by CT imaging after presentation and hospitalization with symptoms of acute cholecystitis. After resolve of the acute symptoms, the aneurysm was resected and the proximal inferior mesenteric artery interponated with a reversed saphenous vein bypass graft. Besides presenting this case we review the literature concerning the rare descriptions of inferior mesenteric artery aneurysms.

The present study was carried out on fifteen healthy adult White New Zealand rabbit (Orycotolagus cuniculus) to clarify the obscure mesenteric arteries, which and their branches which are usually involved in intestinal surgery. The mesenteric artery is a high caliber vessel, 2cm in length dependent on the abdominal aorta, right below the emergence of the vessels destined for the liver and stomach. The animals were sacrificed, injecting diazepam (30 mg/kg) in jugular vein. Cannulation of the abdominal aorta, perfusion with warmed water (40ºC) and stained latex injection (Neoprene 450, Capitol Scientific, Austin, U.S.A, Red carmine stain) were performed, followed by fixation. With formalin (10%) the dissection and photographic documents (Casio Cyber-shot, 12.1 mega pixels) made it possible to systemize the arteries and define the vascular patterns of the viscera. The results prone that the cranial mesenteric artery of the White New Zealand rabbit (Orycotolagus cuniculus) arose from the abdominal aorta, at the level of the second lumbar vertebra, entered the cranial mesentery forming its root, then proceeded caudoventrally in the mesojejunum and continued as the last cecal artery. The cranial mesenteric artery gave off: - Caudal pancreaticoduodenal artery to the right lobe of the pancreas and the descending and ascending parts of the duodenum. Middle colic artery, a small vessel (frequently two) arising from the left wall and passing to the transverse colon, Eighteen to twenty jejunal arteries, Ileocecocolic artery to the ileum, cecum, ascending colon, transverse colon and the cranial part of the descending colon. The caudal mesenteric artery arose from the abdominal aorta at the level of the caudal border of the root of the 6th lumbar transverse process, passed caudoventrally in the descending mesocolon, then divided into: left colic artery to the caudal two thirds of the descending colon, and cranial rectal artery to the cranial segment of the rectum. The obtained results were compared with their corresponding in the domestic animals, especially the domestic carnivores and laboratory animals.

Clinical Criteria

Aim.To evaluate the sensitivity and specificity of the clinical criteria for the diagnosis of chronic mesenteric ischemia in elderly and senile patients with mesenteric atherosclerosis. Materials and methods.The study included 142 patients (82 men and 60 women). The median age of patients is 66.0 [62.0; 72.0] years. Results.According to MDCT atherosclerotic lesions of the abdominal aorta and its unpaired visceral branches were diagnosed in 105 (73.9%) patients. A combination of atherosclerosis of the celiac trunk and the superior mesenteric artery with the presence of hemodynamically insignificant stenosis was revealed. Hemodynamically significant atherosclerotic narrowing of at least one mesenteric artery was present in 15% of cases. Among them, a single vascular lesion was found in 6 patients (4.2%), a combination of hemodynamically significant lesions of two arteries in 15 (11%) patients. Depending on the clinical manifestations, all patients are divided into two groups: the first group 30 (21.1%) patients with the presence of symptoms characteristic of chronic mesenteric ischemia (CMI). The second group consisted of 112 (78.8%) patients without a characteristic triad of symptoms. The clinical symptom complex of СMI, including postprandial abdominal pain, intestinal dysfunction and progressive weight loss, as a diagnostic criterion showed low sensitivity 13.3% and specificity 77.9%. At the same time, the sensitivity of such a clinical combination as a combination of atherosclerosis of the arteries of the lower extremities, weight loss and abdominal pain syndrome with a severity of more than 5.5 points, with respect to the detection of hemodynamically significant stenoses of two or more mesenteric arteries was sensitivity 86.7%, specificity 74.0%.

Objective: to study the features of the topography of the unpaired visceral branches of the abdominal aorta in men and women at different periods of adulthood.Material and methods. We analyzed 190 (93 male and 97 female) computer scans of the abdominal aorta with no cases of vascular and other pathology detected in the patients.Results. It has been found that the topographic parameters of the unpaired visceral branches of the abdominal aorta change with age in both the men and women. In the women in all age groups, the orifice of the celiac trunk is located higher than in the men. In 31.3 % of the women, the origin of the celiac trunk corresponds to the Th12–L1 level of the intervertebral disc, and in 37.0 % of the men — to the intervertebral disc L1–L2. The orifice of the superior mesenteric artery is skeletotopically located at the level of the middle of the body L1 in 25.9 % of the men and in 25.2 % of the women. The orifice of the inferior mesenteric artery in 40.4 % of the men corresponds to the lower edge of the body L3, and in 36.4 % of the women — to the level of the middle edge of the body L3.Conclusion. The obtained data on the sex and age characteristics of the position of the orifice of the celiac trunk, superior and inferior mesenteric arteries are not only of anatomical interest, but also of clinical significance in angiography, abdominal surgical interventions and in X-ray endovascular surgery.

Study Results

Background : The mesenteric blood supply is a combination of rich collateral networks. There are frequent anatomical variants encountered and these variations are sometimes involved in pathologies. Treatment of which requires a better understanding of the variations in the normal anatomy of the inferior mesenteric artery. Methods : The present study was carried out in the Department of Anatomy, Prathima Institute of Medical Sciences, Karimnagar. A total of n=50 specimens, with n=17 adult males and n=2 adult female cadavers and fetuses of which n=26 were term and n=2, was preterm. Female fetuses n=2 of term and n=1 preterm were included in the study. Results : The following variations were observed in the present study of course and variations in the branches of the inferior mesenteric artery and are grouped into three types. Type I: In this type middle colic artery is arising from the inferior mesenteric artery instead of the superior mesenteric artery. It is a rare-variations and observed in a female fetus. Type-II: Four Sigmoidal arteries are arising from an inferior mesenteric artery, after the origin of the left colic artery. This type is observed in a male fetus. Type-III: Three Sigmoidal arteries are originated from the inferior mesenteric artery. This type was observed in a male adult and a male fetus. Conclusion: Out of the 50 cases included in the study we found type 1 variation of IMA in 2% of cases, type 2 variation was found in 2% samples, and type 3 variation was found in 4% of samples. Based on the variations radiologists and Surgeons should be aware of possible consequences when doing colectomy, right hemicolectomy, left hemicolectomy, sigmoidectomy, en-bloc resection of the head of the pancreas, aneurysm, and chronic bowel ischemia. The present study is also useful for reconstructive surgeries in inferior mesenteric arteries in the case of ischemia.

Abstract Our study was conducted on a total of 46 CT angiographies, performed on a GE LightSpeed VCT 64-slice CT installation. Benchmarks were followed in relation to the gender of the person examined. The origin of the superior mesenteric artery relative to the spine we found it in a range between T12 vertebra and L1-L2 intervertebral disc. The T12 vertebra origin was localized in 2 cases (4.35% of cases), both in women. Superior mesenteric artery originated at the level of L1 in 78.26% (90.91% of male cases and in 66.67% of women cases). In 8 cases (17.39% of cases) the origin of the superior mesenteric artery was located at the L1-L2 intervertebral disc. Endolumenal vertical diameter of the superior mesenteric artery orifice we found it in the range of 5.6 to 10.9 mm (6.9 to 10.9 mm in men, and 5.6 to 8.6 mm in women). Horizontal diameter sizes ranged from 4.9 to 9.7 mm, having 6.4 to 9.7 mm in men and 4.9 to 8.3 mm in women. Vertical diameter in males was higher in 59.09% of cases, with differences between 0.1 to 2.4 mm, and in 40.91% of cases the horizontal diameter was larger with differences between 0,1-2.1 mm. Vertical diameter in women was higher in 50% of cases, with differences of 0.1-2.0 mm and the other 50% the horizontal diameter was larger, with differences ranging from 0.1 to 2.2 mm. The angle that the superior mesenteric artery makes it with the aortic wall we found between 16,60-120,8o, males having values between 24,8-120,8o, and in women 16,7-120,8o. The distance between the origin of the superior mesenteric artery and celiac trunk we found it between 5.0 and 16.5 mm, males having 5.0 to 12.1 mm and women 6.9 -16.5 mm. The distance between the origin of the superior mesenteric artery and right renal artery was ranging between 6.2 to 23.5 mm, in males being 6.5 to 19.1 mm and in women from 6.2 to 23 5 mm. The distance between the origin of the superior mesenteric artery and left renal artery we found between 5.7 to 23.5 mm, in males being 5.7 to 21.2 mm, and in women from 6.2 to 23 5 mm. The distance between the aortic origin of the superior and inferior mesenteric arteries was ranging between 50.6 to 91.2 mm, in males being 50.6 to 91.2 mm and in women from 58.2 to 88.4 mm.

Colic Artery

Superior mesenteric artery, the second ventral branch of the abdominal aorta, supplies the distal duodenum, the small intestine, and the large intestine to the mid transverse colon. Superior mesenteric artery branches include the inferior anterior and inferior posterior pancreaticoduodenal arteries, middle colic artery, right colic artery, ileocolic artery, jejunal and ileal branches. The vascular anatomy of superior mesenteric branches is frequently variant. The explanation of variant vascular anatomy of branches and pathological consequences of diseases which impact the mesenteric vasculature might be due to the changes that appear in the development of ventral splanchnic arteries and their blood supply. Knowledge of mesenterical variations is valuable to radiologists and surgeons.
