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.

Computer tomograms of the abdominal part of the aorta and its unpaired branches of adults belonging to three age groups are analyzed: the first, the second mature, and the elderly. It has been established that individual morphometric parameters of the abdominal part of the aorta and its unpaired branches in men and women significantly change with age. It is proved that the diameter of the aorta at different levels significantly increases with age from the first mature age to the elderly by an average of 5 mm. In addition, in men, the length of the abdominal aorta, celiac trunk and main trunk of the superior mesenteric artery do not change with age. In women, the length of the celiac trunk increases with age by 5,9 mm, the length of the main trunk of the superior mesenteric artery - by 17 mm. It can be assumed that this fact is due to the structural features of the connective tissue structures of the arterial wall in women, and, in particular, the elastic framework. 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 on average of 12,3°, then in old age an increase of 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 old age, it is on average 4,4 mm larger than in the first period of mature age. In general, a number of morphometric parameters of the abdominal part of the aorta and its unpaired branches significantly changes with age. The findings are important for endovascular interventions.

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.

The article studies the features of the morphometric parameters of unpaired branches of the abdominal aorta in men with different types of physique. An analysis was made of computer scans of the abdominal part of the aorta and its unpaired branches in adult men with different body types, аccording to the classification by V.N. Shevkunenko and According to Pignet index.When using the index V.N. Shevkunenko from the studied angular parameters reliably differs only the angle of discharge of the superior mesenteric artery, in groups systematized by the Pignet index, differences are observed in all angular parameters. Due to the fact that the classification by V.N. Shevkunenko reflects to a greater degree the linear parameters of the body, and the Pignet index is also voluminous (chest girth, body weight), the latter provides a greater number of differences in the compared parameters of the abdominal aorta and its unpaired branches, including those depending on the type and degree of development of the abdominal fat fiber.

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.

In the last few decades there has been a steady growth of vessels diseases, including diseases of the abdominal aorta and its unpaired branches. The aim of this study was to study the topography of the abdominal aorta and its unpaired branches in men and women belonging to different age groups. It was analyzed 266 computer tomograms of the abdominal aorta and its unpaired branches of adult men and women divided into three age groups (first and second periods of mature age and old age). It was found that for men is typical the more distal location of the studied anatomical objects relatively to the vertebral column in comparison with women. It was proved that in women of the first mature age period, as well as in men, most often the beginning of the abdominal aorta is observed at the middle of the Th12 body (35.8%), in the second period of mature age - at the middle of the Th12 body (33.3%); in the elderly - at the level of the lower edge of the body of this vertebra. The level of the aorta bifurcation in men in the first period of mature age are most often located at the level of the lower edge of the L4 body, in other age groups at mid-body L4. While in women the age-related changes of the level of the bifurcation of the aorta is not significant. It was shown that in women in all age groups the outfall of the celiac trunk is localized higher than that in men. Dynamics of age changes of the position of the outfalls of the upper and a lower mesenteric artery, in men and women varies considerably. The obtained information about sex and age characteristics of the position of the abdominal aorta and its bifurcation, the outfalls of the celiac trunk, upper and lower mesenteric arteries have not only anatomical interest but also have clinical importance in surgical interventions on the organs of gastro-splenic-pancreaticoduodenal zone.

In connection with the rapid development of endovascular surgery and the increasing number of minimally invasive surgeries there is a need for a detailed study of variants of the architectonic and topographic and anatomical characteristics of extraorganic blood vessels. The purpose of the study was to study the variant anatomy of the celiac trunk and its branches in adult men and women with different shapes of body. The analysis of 2300 computer tomograms of the abdominal aorta and its unpaired branches of adult men and women in age 25-75 years with a different body type was made. According to the value of the Pinier index, were dedicated asthenic, normosthenic and hypersthenic forms of the physique. It is established that the cases of a typical classic variant of celiac trunk trifurcation in men is observed only in 35% of cases, and in women – in 41.2%, with an atypical variant of its division was observed significantly more often (in 65 and 58,8%, respectively). It is shown that regardless of gender and the shape of the body at Pinier index in all studied groups, the incidence of typical branching of the celiac trunk varies from 32.1 to 49.4%, and the frequency of atypical variant is an average of 62.1%. Among atypical variants of division of the celiac trunk quadrifurcation occurs more often. Thus, the frequency of most of the variants of the celiac trunk showed significant differences depending on gender and body type. Knowledge of variant anatomy of the celiac trunk will be may significantly increase the quality of preoperative diagnosis in surgery on the celiac trunk and its branches, and exclude iatrogenic damage of these vessels.

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).

Abstract The transverse diameter of the abdominal aorta was measured above the origin of the celiac trunk on a number of 82 cases, in male finding a caliber range of 18 to 31.8 mm, in one case, the aorta having a diameter of 31.8 mm. In females, the aorta was between 12.4 to 23.4 mm in caliber, most commonly, in 24 cases, being present a caliber range from 14.8 to 19.7 mm. At the level of the celiac trunk, on a number of 74 cases, the aorta had a diameter of between 12.9 to 28.6 mm in females and 11.4 to 21.8 mm in males. In males, on 20 cases, the caliber was 20 to 25 mm while in females, on 42 cases, we found a caliber range from 11.4 to 21.8 mm and in 20 cases being 19.4 to 2.18 mm. At the level of the superior mesenteric artery, we studied the aortic diameter on a number of 86 cases. In males it had a diameter between 12.9 to 26.4 mm, but in one case with 12.9 mm. In 26 cases, it had a diameter of between 20.1 to 26.4 mm. In females we found a range of 12.5 to 20.4 mm, most commonly with the diameter of 18-20 mm in 19 cases. Next to the renal arteries we studied the aortic diameter on a number of 118 cases, finding abdominal aortic diameters of 10.3 to 27.4 mm. In males it ranged from 10.9 to 27.4 mm diameter while in females had a diameter between 10.3 to 20.4 mm; in one case we met a caliber of 20.4 mm. The diameter of the abdominal aorta at the level of the inferior mesenteric artery was evaluated on 80 cases; in males the diameter ranged from 13.9 to 25.9 mm and in females was 10.6 to 19.3 mm.

AbstractA plate-like structure is located posterior to the portal vein system, between the pancreatic head and roots and/or branches of two major arteries of the aorta: the celiac trunk and superior mesenteric artery. We aimed to clarify the distribution and components of this plate-like structure. Macroscopic examination of the upper abdomen and histological examination of the plate-like structure were performed on 26 cadavers. The plate-like structure is connected to major arteries (aorta, celiac trunk, superior mesenteric artery) and the pancreatic head; it contains abundant fibrous bundles comprising nerves, vessels, collagen fibers, and adipose tissue. Furthermore, it consists of three partly overlapping fibrous components: rich fibrous bundles (superior mesenteric artery plexus) fused to the uncinate process of the pancreas; fibrous bundles arising from the right celiac ganglion and celiac trunk that spread radially to the dorsal side of the pancreatic head and superior mesenteric artery plexus; and fibrous bundles, accompanied by the inferior pancreaticoduodenal artery, entering the pancreatic head. The plate-like structure is the pancreas–major arteries (aorta, celiac trunk, superior mesenteric artery) ligament (P–A ligament). The term “P–A ligament” may be clinically useful and can facilitate comprehensive understanding of the anatomy surrounding the pancreatic head and provide an anatomical basis for further pancreatic surgery studies.
