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.

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.

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.

Background and Aims: There is a demand for a better understanding of the vascular structures around the right colonic area. Although right hemicolectomy with the recent concept of meticulous lymph node dissection is a standardized procedure for malignant diseases among most surgeons, variations in the actual anatomical vascular are not well understood. The aim of the present review was to present a detailed overview of the vascular variation pertinent to the surgery for right colon cancer. Materials and Methods: Medical literature was searched for the articles highlighting the vascular variation relevant to the right colon cancer surgery. Results: Recently, there have been many detailed studies on applied surgical vascular anatomy based on cadaveric dissections, as well as radiological and intraoperative examinations to overcome misconceptions concerning the arterial supply and venous drainage to the right colon. Ileocolic artery and middle colic artery are consistently present in all patients arising from the superior mesenteric artery. Even though the ileocolic artery passes posterior to the superior mesenteric vein in most of the cases, in some cases courses anterior to the superior mesenteric artery. The right colic artery is inconsistently present ranging from 63% to 10% across different studies. Ileocolic vein and middle colic vein is always present, while the right colic vein is absent in 50% of patients. The gastrocolic trunk of Henle is present in 46%–100% patients across many studies with variation in the tributaries ranging from bipodal to tetrapodal. Commonly, it is found that the right colonic veins, including the right colic vein, middle colic vein, and superior right colic vein, share the confluence forming the gastrocolic trunk of Henle in a highly variable frequency and different forms. Conclusion: Understanding the incidence and variations of the vascular anatomy of right side colon is of crucial importance. Failure to recognize the variation during surgery can result in troublesome bleeding especially during minimal invasive surgery.
