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.

BACKGROUND: Variations in the branching pattern of the axillary artery are a rule rather than an exception. The knowledge of these variations is of anatomical, radiological, and surgical interest to explain unexpected clinical signs and symptoms. OBJECTIVE: The large percentage of variations in branching pattern of axillary artery is making it worthwhile to take any anomaly into consideration. The type and frequency of these vascular variations should be well understood and documented, as increasing performance of coronary artery bypass surgery and other cardiovascular surgical procedures. The objective of this study is to observe variations in axillary artery branches in human cadavers. METHODS: We dissected 80 limbs of 40 human adult embalmed cadavers of Asian origin and we have studied the branching patterns of the axillary artery. RESULTS: We found variations in branching pattern of axillary artery in 62.5% of the limbs. Anatomical variations included: origin of lateral thoracic artery from the subscapular artery; absent thoracoacromial trunk and all its branches arose directly from the second part of the axillary artery; division of thoracoacromial trunk into deltoacromial and clavipectoral trunks, which were divided into all branches of thoracoacromial trunk; origin of subscapular, anterior circumflex humeral, posterior circumflex humeral and profunda brachii arteries from a common trunk from the third part of the axillary artery; and origin of posterior circumflex humeral artery from brachial artery in addition to third part of the axillary artery. CONCLUSIONS: The study was carried out to show important variations in the branching pattern of axillary artery, in order to orient the surgeons performing angiography, coronary bypass, and flaps in reconstructive surgeries.

Abstract Background: An intimate knowledge and awareness of branching patterns of main portal vein is necessary before hepatic surgeries. The presence of portal vein variants increases the risk of bile duct hilar anatomical variations also. This information may be of help for accurate radiological interpretation, to prevent complications like hemorrhage, difficult anastomosis in the recipient, ischemia in the graft and allograft failure at the time of liver transplantation. Hence the present study was conducted with the objective of observing the branching pattern of the main portal vein, to measure length of right portal vein and angle between right and left portal vein. Material and Methods: The present study was conducted on 84 liver specimens of human cadavers fixed with 5% formalin, collected from the Department of Anatomy and Forensic Medicine, MMC&RI, Mysore. The parameters were measured using image J software. Results: Bifurcation of main portal vein was seen in 75 liver specimens [89.3%]. Trifurcation of main portal vein was seen in 9 specimens [ 10.7%]. Mean angle between Right and left portal vein was 146.7°. Mean length of right portal vein was 2.27 cm. Conclusion: Knowledge of portal vein variations is critically significant in surgical resection and transplantation procedures. Resection of any portion of liver should be well planned and clear identification of sub segments of liver is necessary before surgery. Surgeons and radiologists must have a thorough understanding of variants in portal vein anatomy in order to prevent injury to portal vein and for successful radiological interventions.

BACKGROUND: Many anatomical variations have been associated with the Celiac Trunk, of which most are classified as being asymptomatic. CASE PRESENTATION: In this article, we describe yet another anatomical variation involving the Celiac Trunk, Superior Mesenteric artery and the Inferior Pancreaticoduodenal Artery during routine cadaveric dissection. We identified a fourth branch of the Celiac trunk (quadrification) that communicated with the Superior Mesenteric artery at the point of origin of the Inferior Pancreaticoduodenal artery which we concluded to be the Anterior Inferior Pancreaticoduodenal artery. CONCLUSION: This anastomosis could be essential in the case of occlusion between the Celiac Trunk and the Superior Mesenteric artery.

Knowledge of anatomical variations of the limb’s main arteries is significant for the clinicians. Thus, this study is aimed at examining the branching pattern and anatomical variations of the axillary artery. We conducted research on 59 upper limbs of adult human donated cadavers. All axillary artery branches’ origins were assessed, and the correlations between points of origins and variations of specific branches were evaluated. The average length of the axillary artery was found to be 11.22 cm, and this length was defined as reference line. Based on this reference line, the first, second, and third parts were 37.56%, 39%, and 30.05%, respectively. The STA was originated from 25.11%. The TAA and LTA were 42.67% and 54.82%, respectively. The SSA, ACHA, and PCHA were 64.72%, 83.89%, and 84.53%, respectively. The origin of LTA was correlated with that of SSA ( R = 0.473 , P < 0.05 ) and AHCA ( R = 0.307 , P < 0.05 ), respectively. And there was a positive correlation between AHCA and PHCA ( R = 0.705 , P < 0.05 ). The number of branches ranged from 3~6, and 9 types were shown. The most frequent branching pattern was common origin of the LTA and SSA (22/59). And AHCA and PHCA were originated together in 19 cases, and both patterns were combined in 12 cases. TTA and LTA branched together in 9 cases, and common trunk for the SSA, PHCA, and AHCA was found in 2 cases. According to this pattern, the origin of LTA and PCHA was significantly different. This information is particularly useful for surgeons and clinicians.

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.

Abstract Introduction Delineation of variant anatomy in celiac trunk and superior mesenteric artery including its origin and branching pattern and variations in branching pattern of hepatic artery in patients of hepatopancreaticobiliary malignancy with the use of mutidetector CT (computed tomography) angiograpgy was performed. Materials and Methods All CT examinations were performed on a 64-multidetector computed tomography (MDCT) scanner. Technical features of multislice computed tomography (MSCT) are as follows: 64 mm × 1 mm collimation, minimum slice thickness of 0.625, gantry rotation time of 320 ms, 120 kV, and 320 mAs. CT angiography was performed with intravenous (IV) administration of nonionic contrast material, that is, iodixanol (Visipaque). The contrast medium and saline solution were injected with a Medrad power injector at 3 mL/sec through an 18-gauge plastic intravenous catheter placed in an antecubital vein in most of the cases. Contrast medium volumes varied between 100 and 150 mL at 1.5 mL/kg. Images were obtained in triphasic pattern at arterial (20–30 seconds), portal (60–70 seconds), and equilibrium (at 3 minutes) phases. Results Five types of celiac axis anatomic variations and nine type of variants in celiac axis branching was found in the study sample of 124 patients. Classical celiac axis anatomy was seen in 92.7% of the cases, while the five types of variation in branching were found in nine patients. Majority of cases showed pattern I (59.6%) followed by patterns V (12.1%), II (9.7%), and III (8.9%). There were three (2.4%) cases each showing pattern VIII and AA, and two (1.6%) cases each showing patterns IV and VI, respectively. There was one (0.8%) case each showing pattern VII and IX. A total of three (2.4%) cases showed right hepatic artery arising from celiac axis. Conclusion We conclude that most common pattern of celiac axis and superior mesenteric artery (SMA) branching is classical pattern (92.7%) which is in concordance with literature. Type-I pattern of hepatic artery branching was most common (59.6%), similar to that documented in literature. Although the most common variation in our study is type V (12.1%), followed by types II (9.7%) and III (8.9%), the most common variation in most of the literature was found to be type III. CT angiography hence is an excellent diagnostic modality for depiction of arterial anatomic variations and provides a roadmap for surgical treatment.
