“…The splenic artery (SA) is described as the first branch of CT (2.5%) 7 , but these morphological features were not observed in our study. The length of the SA was 92.5 mm, while in other studies the range fluctuates from 76.5 to 94.1mm 1,27 . Concerning the tortuosity of the SA, the results from Fataftah et al 2020 27 report 94.1mm for the straight SA, and 155 mm for the tortuous SA, with a tortuosity index (TI) of 1.63, higher than our TI of 1.25.…”

Silvester et al 19 found, in cadavers and using angiography imaging, a TI range for cadavers of 1.01-3.58, and higher in the imaging analysis (5.25 TI), with no correlation between the TI of the SA and female gender, body mass index, abdominal cavity diameter, nor age.…”

Objective: to evaluate the morphology of the branches of celiac trunk (CT), left gastric (LGA), common hepatic (CHA), and splenic (SA) arteries in cadaveric specimens from a sample of a Colombian population. Methods: descriptive cross-sectional study of 26 blocks from the abdominal upper segment of human cadavers who underwent forensic autopsies at the Instituto de Medicina Legal at Bucaramanga, Colombia. The vascular beds of the celiac trunk were, subsequently, perfused with a semi-synthetic resin. Results: the diameters of LGA, CHA, and SA were 3.6±0.8mm, 5,2±1.2mm, and 5.9±1.0mm, respectively. Statistically, LGA and SA were different (p=<0.001). SA followed a linear trajectory in 8 (31%) samples, slightly tortuous in 4 (15%), and tortuous in 14 (54%). The tortuosity index was 1.25±0.18. Of the branches of CHA, the proper hepatic artery (PHA) had 4.8±1.2mm in diameter and 18.8±9.1mm in length, whereas the gastroduodenal artery (GDdA) had 4.1±0.8mm. In 2 cases (7.7%), an accessory hepatic artery from the LGA was found to supply perfusion to the left hepatic lobe. Finally, in 2 cases (7.7%) the SA came independently from the abdominal aorta. Conclusion: the observed emergence incidence of the CT branches from the same level as reported in the literature is lower. The characterization, along with their variants, of LGA, CHA, and SA must be considered in surgical procedures in the upper abdominal segment, to avoid iatrogenic complications.

“…However, one of the studies of the tortuosity of the splenic artery did not reveal a relationship with age or body weight, but instead indicated a relationship between the female sex and a high degree of tortuosity. The authors suggested that this is due to the peculiarity of the influence of female sex hormones on the walls of blood vessels [ 15 ]. However, Brinkman and coworkers did not find any relationship between splenic artery loops and age or sex but determined that the length of the artery in contact with the pancreas decreased with age [ 12 ].…”

Background: Precise knowledge of the topographic features of the splenic artery and its branches in the hilum region is of practical interest due to the various interventions on the vessels of the spleen. Materials and methods: The anatomy of the spleen was studied by means of macroscopic dissection on 330 organ complexes, which were carefully documented and analyzed statistically. Results: The analysis of the splenic artery trajectory led to identification of four types: straight (43.03%), sinusoidal (27.58%), serpentine (20.91%) and alternating (8.48%). To assess the relation between the trajectory of the splenic artery and its branches we performed a chi square test. Sinuous or serpentine trajectory was associated with the presence of long splenic artery branches (dorsal pancreatic artery or the great pancreatic artery), X2 (2, N = 330) = 12.85, p = 0.001. The artery was located suprapancreatic in 70.30% of cases, anteropancreatic in 4.55%, the vessel had an intrapancreatic course in 14.85% and in 10.00% of cases the artery was located retropancreatic. The presence of inferior polar arteries was associated with a longer pancreas (Spearman’s correlation; r = 0.37; p = 0.037). In a multiple regression analysis, inferior polar arteries predicted the length of the pancreas although only a small number of cases could be explained by this model (R2 = 0.127, Adjusted R2 = 0.098; Betta = 0.357; t(330) = 2.091; p = 0.045). There were 30 (9.09%) cases of accessory spleens. Conclusions: The arterial supply of the spleen is highly variable in its trajectory, terminal branches, and relation to other organs. The splenic artery tends to be sinuous or serpentine in zones when a large artery branches off (e.g., the dorsal pancreatic or greater pancreatic artery). Multiple short branches tend to stabilize the trajectory of the splenic artery. Inferior polar arteries and accessory spleens contribute to the length of the pancreas, most likely due to increased vascular supply to the tail of the gland.

RESUMO Objetivo: avaliar a morfologia dos ramos das artérias do tronco celíaco (CT), gástrica esquerda (LGA), hepática comum (HC) e esplênica (SA) em espécimes cadavéricos de uma amostra de uma população colombiana. Métodos: estudo transversal descritivo de 26 blocos do segmento superior abdominal de cadáveres humanos submetidos a necropsias forenses no Instituto de Medicina Legal de Bucaramanga, Colômbia. Os leitos vasculares do tronco celíaco foram, posteriormente, perfundidos com resina semissintética. Resultados: os diâmetros de LGA, CHA e SA foram 3,6±0,8mm, 5,2±1,2mm e 5,9±1,0mm, respectivamente. Estatisticamente, LGA e SA foram diferentes (p=<0,001). A SA seguiu uma trajetória linear em 8 (31%) amostras, levemente tortuosa em 4 (15%) e tortuosa em 14 (54%). O índice de tortuosidade foi de 1,25±0,18. Dos ramos do ACS, a artéria hepática própria (APH) tinha 4,8±1,2mm de diâmetro e 18,8±9,1mm de comprimento, enquanto a artéria gastroduodenal (GDdA) tinha 4,1±0,8mm. Em 2 casos (7,7%), uma artéria hepática acessória do GIG foi encontrada para fornecer perfusão ao lobo hepático esquerdo. Finalmente, em 2 casos (7,7%) a SA veio independentemente da aorta abdominal. Conclusão: a incidência observada de emergência dos ramos de TC do mesmo nível relatado na literatura é menor. A caracterização, juntamente com suas variantes, de LGA, CHA e SA deve ser considerada em procedimentos cirúrgicos no segmento abdominal superior, para evitar complicações iatrogênicas.
