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.

Vascular Variations

Major sources of the vascular supply of the gastrointestinal tract are the celiac trunk (CT) and superior mesenteric artery (SMA) which are the main proximal branches of the abdominal aorta. The CT gives rise to three branches normally as follows: left gastric artery (LGA), common hepatic artery (CHA) and splenic artery (SA). The branching pattern of the CT is considered as the most literature explained anatomical pattern.1 After the CT, the abdominal aorta gives the second named branch as superior mesenteric artery. Vascular variations of the celiac trunk and superior mesenteric artery are common and had been described earlier.2 These variations are caused due to the aberrant embryological development of splanchnic arteries. The incidence of hepato-spleno-mesenteric trunk has been reported by various authors as 0.68 %,3 0.7 %,4 0.3 %,5 0.4 %,6 or 1 %.7 The importance of knowledge of these variations lies in preplanning of invasive surgical techniques, organ transplantation, diagnosis, prevention, and management of some metastatic tumours and to overcome the catastrophic consequences like bowel ischemia due to common trunk.8 Hence a better understanding of these anatomical variations is considered vital for surgeons or radiologists for appropriate planning and conduction of surgical procedures or interventions.9 Most of the anatomical variations in abdominal aorta branches are asymptomatic and incidental findings while imaging for other aetiologies. But the identification of such vascular variations is of utmost importance in clinical practice. The Hepatospleno-mesenteric trunk [HSMT] is one of those variations and was less frequently reported. The authors describe a case report of the hepato-spleno-mesenteric trunk which was incidentally detected in the multi detector computed tomography study of the abdomen of a 54-year-old male patient who had been diagnosed to have chronic liver disease and hepatic encephalopathy. The origin of the HSMT [with a diameter of 11mm] occurs from the abdominal aorta at the level of the L2 vertebral body and is divided into the hepatosplenic trunk [diameter of 7 mm] and superior mesenteric artery [diameter of 7.5 mm] after coursing for a length of 28 mm. The hepatosplenic trunk ascends superiorly for a length of 20 mm and divided into two terminal branches: common hepatic (6 mm) and splenic artery (6 mm).

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.

The rapid development of transplantation, endovascular and minimally invasive surgery necessitates a detailed study of the structural features of the vessels of the abdominal cavity. The purpose of the study is the characteristics of the morphometric parameters of the abdominal aorta and its unpaired branches in men and women at different ages and depending on the body type. The analysis of 266 computer tomograms of the abdominal part of aorta and its unpaired branches was carried out in adult men women divided into three age groups (first and second periods of mature age and elderly age), as well as into three groups according to the Pinier index (asthenic, normosthenic and hypersthenic body types). It was established that individual morphometric parameters of the abdominal part of aorta and its unpaired branches in men and women significantly change with age. It is proved that the diameter of the aorta at various levels significantly increases with age from the first mature to the elderly age by an average of 5 mm. However, in men, the length of the abdominal aorta, celiac trunk and main trunk of the superior mesenteric artery does not change with age. In women, the length of the celiac trunk increases with age at 5.9 mm, the length of the main trunk of the superior mesenteric artery - at 17 mm. The angle of discharge of the celiac trunk in men changes unevenly with age - in the second period of mature age, there is a statistically significant decrease by an average to 12.3°, then in old age an increase to 15°. Moreover, in women, the values of this indicator vary more evenly. The angles of discharge of other vessels did not show a clear age dependence, since this parameter is largely due to the constitutional features. The aorto-mesenteric distance changes with age only in women. In elderly age, it is on average 4.4 mm larger than in the first period of mature age. It was also found that there are significant differences between constitutional types identified using the Pinier index in the overwhelming majority of the morphometric parameters studied. The obtained information has a significant clinical importance, since it will allow objectifying the diagnostic criteria of various vascular syndromes and minimizing the risk of endovascular interventions.

(1) Background. The vertebral level of origin (VLO) of the celiac trunk (CT) and superior mesenteric artery (SMA) has been scarcely investigated. (2) Method. This study used 107 computed tomography angiograms and an eleven type grading system to classify the VLO of the CT and SMA. Each of the T12–L2 vertebra were divided in three horizontal levels. The intervertebral discs were considered distinct levels. (3) Results. The VLO of the CT ranged from the upper third of the T12 vertebra to the lower third of the L1 vertebra. The VLO of the SMA ranged from the lower third of the T12 vertebra to the upper third of the L2 vertebra. There was a highly significant association between the VLO of the CT and SMA (Chi2 = 201, p < 0.001), usually respecting a “plus two” rule. The mean CT–SMA distance was 1.82 +/− 0.66 cm in males and 1.55 +/− 0.411 cm in females, the difference being statistically significant. The mean CT–SMA distance tended to decrease with increasing CT–SMA types, the differences being statistically significant. (4) Conclusions. These characteristics of CT and SMA origins and their relations should be known by surgeons, as they could impact operative management and should be evaluated on a case-by-case basis.

The aim of this study was to detect and describe the existence and incidence of anatomical variations of the celiac trunk and superior mesenteric artery. The study was conducted on 150 persons, who underwent abdominal Multi- Detector Computer Tomography (MDCT) angiography, from April 2010 until November 2012. CT images were obtained with a 64-row MDCT scanner in order to analyze the vascular anatomy and anatomical variations of the celiac trunk and superior mesenteric artery. In our study, we found that 78% of patients have a classic anatomy of the celiac trunk and superior mesenteric artery. The most frequent variation was the origin of the common hepatic artery from the superior mesenteric artery (10%). The next variation, according to frequency, was the origin of the left gastric artery direct from the abdominal aorta (4%). The arc of Buhler as an anastomosis between the celiac trunk and superior mesenteric artery, was detected in 3% of cases, as was the presence of a common trunk of the celiac trunk and superior mesenteric artery (in 3% of cases). Separate origin of the splenic artery and the common hepatic artery was present in 2% of patients. The MDCT scanner gives us an insight into normal anatomy and variations of the abdominal blood vessels, which is very important in the planning of surgical interventions, especially transplantation, as well as in the prevention of complications due to ischemia.

Abstract Background Abdominal circulation plays the important physiological role for structure and function of the digestive system, maintenance of nutrient homeostasis. Purpose To study the features of abdominal hemodynamics in patients with visceroptosis. Methods We studied 69 patients (mean age 22.28±3.7 years) with splanchnoptosis (visceroptosis) and 52 age- and sex- matched patients without splanchnoptosis (controls). Exclusion criteria: a history of digestive system surgery of taking blood circulation activating drugs. Doppler ultrasonography of the common hepatic artery, splenic artery, superior mesenteric artery, portal vein was performed on an empty stomach and 30 minutes after a food sample (standardized for proteins (14 g), fats (10 g) and carbohydrates (45 g)) using the Sonoace-8000 ultrasound scanner (Medison, South Korea). The data were analyzed using the Statistica-6 packages. Results There were no differences in hemodynamic parameters of fasting abdominal blood flow (ABF). After a food testing, in the postprandial period the ABF in all vessels in patients with splanchnoptosis was lower than in controls: the portal vein blood flow (BF) 1124,0 [1030,0–1419,0] ml/min vs 1373,0 [1136,0–1567,5] ml/min respectively (U=433,5; Z=−2,1; p=0,0342); the common hepatic artery BF 341,0 [295,0–394,0] ml/min vs 412,0 [331,0–521,0] ml/min respectively (U=335,0; Z=−2,3; p=0,0218); the splenic artery BF 396,0 [292,0–538,0] ml/min vs 502,0 [394,0–594,0] ml/min respectively (U=328,0; Z=−2,1; p=0,0399); the superior mesenteric artery BF 988,0 [837,0–1272,0] ml/min vs 1136,5 [992,0–1465,0] ml/min respectively (U=1625,5; Z=−2,2; p=0,0314). Changes in ABF were correlated with splanchnoptosis: the portal vein BF with any ptosis (rs=−0,21; p&lt;0.05), the common hepatic artery BF with gastroptosis (rs=−0,38; p&lt;0.05), the superior mesenteric artery BF with colonoptosis (rs=−0,86; p&lt;0.05). The peripheral vascular resistance was correlated with the common hepatic artery BF (rs=−0,46; p&lt;0.05), with the splenic artery BF (rs=−0,33; p&lt;0.05) and with the superior mesenteric artery BF (rs=−0.79; p&lt;0.05). Conclusions Patients with splanchnoptosis in the postprandial period have low volumetric BF in abdominal aorta vessels. This can be associated with the length of the mesenteric vessels, which undergoes the greatest changes in splanchnoptosis. Food testing reveals latent BF deficit in patients with splanchnoptosis.
