BACKGROUND Superior Mesenteric Artery (SMA) is one of the anterior branches of the abdominal aorta. It originates from abdominal aorta at the level of lower border of first lumbar vertebra, one centimeter below the coeliac trunk. It gives the first branch inferior pancreaticoduodenal artery (IPDA), The colic branches arise from concave right side of the superior mesenteric artery, these are middle colic artery (MCA), right colic artery (RCA), ileo colic artery (ICA). Jejunal and ileal branches arise from left side of the SMA. Superior mesenteric artery supplies derivatives of midgut. Knowledge of branching pattern of the SMA is clinically important to gastroenterologists operating on gut and neighboring structures like pancreas, duodenum, and liver. We wanted to study the variations in the branches of superior mesenteric artery. METHODS This is a descriptive study conducted on 50 adult embalmed human cadavers by conventional dissection method, the findings were noted and tabulated. RESULTS Present study shows that inferior pancreatic duodenal artery orginated from SMA in 47 (94 %) specimens. IPDA was absent in 3 (6 %) specimens. Middle colic artery was found to arise from SMA in 48 (94 %) and MCA was absent in 2 (4 %) specimens. Right colic artery was found to arise from SMA in 47 (94 %) specimens and it was absent in 3 (6 %) specimens. Ileo-colic artery was found to arise from SMA in all 50 (100 %) specimens. CONCLUSIONS Awareness of these complex variations may prevent devastating complications during colonic surgeries. Variations in the branching pattern of superior mesenteric artery is essential for surgeons operating on derivatives of midgut, liver, pancreas.

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.

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.

Background: Splenic artery is the largest branch of the celiac trunk in adults and is the second-largest next to the common hepatic artery in fetal life. The present study was conducted to assess variation in the branching pattern of the splenic artery. Subjects and Methods: The present cadaveric study was conducted on 54 cadavers embalmed with 10% formalin. The peritoneal cavity was opened and explored. The celiac trunk, splenic artery and its branches were noted and photographed. Results: out of 54 cadavers, 26 were males and 28 were males. The origin of the splenic artery was from the celiac trunk in 47, a superior mesenteric artery in 4 and abdominal aorta in 3 cases. The difference was significant (P< 0.05). Conclusion: Authors found that surgeons should have a thorough knowledge regarding the branching pattern of the splenic artery. There was variation in the origin of the splenic artery such as from celiac trunk, superior mesenteric artery and abdominal aorta.

Endovascular Stent Placement

Endovascular stent placement (ESP) for patient with spontaneous isolated dissection of the superior mesenteric artery (SIDSMA) is a widely accepted treatment option. However, failed percutaneous ESP is not uncommon and is one of the leading causes for laparotomy. We report a case of 63-year-old man with SIDSMA encountered failed antegrade recanalization via conventional transfemoral approach. We achieved recanalization in a retrograde fashion through middle colic artery using rendezvous technique and successfully placed self-expandable stents inside the dissected superior mesenteric artery. The patient recovered well after percutaneous ESP. We herein describe the transcollateral retrograde approach of percutaneous ESP for SIDSMA as an alternative option when conventional antegrade recanalization fails.
