“…The trifurcated presentation was present in 4.53%. The findings are similar to those observed in a Brazilian study with 60 arteriographies, in which the bifurcated type appeared in 93.3%, and the trifurcated, in 6.7% 20 . Regarding terminal splenic ramifications, the most frequently found were those of three (34.90%) and four arteries (34.10%).…”

Objective: to determine the prevalence and describe the main morphological and metric variations of the splenic artery in terms of its origin, path and polar and terminal branches. Methods: cross-sectional study, carried out at Hospital de Clínicas between July and November 2020. Computed tomography scans were analyzed with intravenous contrast of the patients seen at the Radiology and Diagnostic Imaging Service. The findings were categorized as to origin, path and splenic ramifications. Results: 1,235 patients were evaluated. As for the origin, the splenic artery appears in the celiac trunk in 99.11% of the individuals. Of these, 5.95% have a bifurcated celiac pattern, 92.17% trifurcated and 1.88% tetrafurcated. The mean arterial diameter was 5.92mm (±1.2), the highest one being in white men. As for the path, the splenic artery was unique in the entire sample. The suprapancreatic course was found in 75.63% of the individuals, with a higher occurrence in women, 78.87% (p<0.001). The terminal splitting pattern of the splenic artery was characterized by the bifurcated type (95.47%). The terminal branches seen most frequently were those with three arteries (34.90%) and most individuals did not have polar branches. Conclusion: the splenic artery presents a highly variable pattern of origin and its average caliber is influenced by sex and color. The suprapancreatic path was the most characteristic and predominant in females. The bifurcated pattern of final division, with three terminal branches and the absence of polar arteries, occurs more frequently.

“…Achado também encontrado com pouca frequência nos estudos de Melo (2011), em cervídeos, Takci (2009), em bovinos, e Schimming e Abreu (2001), em tatus. A ramificação extraparenquimatosa com ramos colaterais, secundários ou terciários da artéria esplênica, dirigidos às extremidades do baço, recebem a denominação de artérias polares em humanos, como observado na extremidade dorsal no baço de cutias, e são relativamente importantes na orientação dos cirurgiões no momento de realizar a desvascularização de determinada área do órgão (SILVA et al, 2011).…”

A B S T R A C TThis research aimed to evaluate the topography, external morphology, the intraparenchymal branching and distribution of the linens arterial vessels of the spleen of the cutia (Dasyprocta prymnolopha). Twenty spleens were analyzed of young and adult animals, thirteen males and seven females, from the Center for the Study and Preservation of Wild Animals of the Agricultural Sciences Center of the UFPI. In sixteen spleens, the topography and the external morphology were verified "in situ" after the opening of the abdominal cavity. For the study of arterial vascularization, ten organs were used, six of them were removed from the abdominal cavity, and injected with 60% latex Neoprene through the linens artery, fixed with 10% aqueous solution of formaldehyde, and dissected. In four other spleens, the artery was filled with a solution of colored vinyl acetate, submitted to the corrosion method, using 30% sulfuric acid, obtaining the vascular molds. The spleen of the cutia with triangular shape was verified in 68.7%, and in 31.3%, rectangular. The linens artery, always with extra-parenchymal division, originates from 5 to 12 branches, predominantly 6 branches, in 40% of cases, that penetrate the parenchyma, vascularize independent territories, characterizing the arterial segments. In 20% of the spleens examined, we observed extrahilar arteries and, in only 1 case (10%) an anastomosis was seen between the segmental arterial branches. K E Y W O R D SAnatomy, Splenic artery, Wild animals R E S U M OEsta pesquisa teve por objetivo avaliar a topografia e morfologia externa, ramificação e distribuição intraparenquimal dos vasos arteriais lienais do baço de cutia (Dasyprocta prymnolopha). Foram analisados vinte baços de animais jovens e adultos, treze machos e sete fêmeas, procedentes do Núcleo de Estudos e Preservação de Animais Silvestres do Centro de Ciências Agrárias da UFPI. Em dezesseis baços, verificou-se "in situ" a topografia e a morfologia externa, após a abertura da cavidade abdominal. Para o estudo da vascularização arterial, foram utilizados dez órgãos, destes, seis foram retirados da cavidade abdominal, injetados com Neoprene látex a 60%, por meio da artéria lienal, fixados com solução aquosa de formaldeído a 10%, e dissecados. Em outros quatro baços, procederam a repleção da referida artéria, com solução de acetato de vinil corado, submetidos ao método de corrosão, utilizando-se ácido sulfúrico a 30%, obtendo-se os moldes vasculares. Verificou-se o baço da cutia com formato triangular em 68,7%, e em 31,3%, retangular. A artéria lienal, sempre com divisão extra-parenquimal origina de 5 a 12 ramos, preponderantemente, 6 ramos, em 40% dos casos, que penetram no parênquima, vascularizam territórios independentes, caracterizando os segmentos arteriais. Em 20% dos baços examinados, observou-se artérias extra-hilares e, em apenas 1 caso (10%) foi visto uma anastomose entre os ramos arteriais segmentares.

“…Furthermore, the length of a splenic polar artery in reference to the distance from its point of origin to the splenic hilum is an additional clinically relevant feature. An investigation by Silva et al examined 11 splenic polar arteries and found the average distance between the arterial point of origin and the splenic hilum was 4.85 cm [ 17 ]. This greatly contrasts with the distance of 8.0 cm described in this case presentation.…”

The splenic artery is the largest branch of the celiac trunk and frequently presents with anatomical variability. These variations relate to its origin, trajectory, location relative to the pancreas, terminal branching pattern, and the potential presence of polar arteries. Knowledge of the splenic artery's variability may inform gastrointestinal surgeons as they plan and execute surgical interventions, resulting in improved success rates while minimizing both operative complications and procedural time. The case presentation of a splenic artery dissected from an elderly male cadaver initially demonstrated normal anatomical arrangement. The artery branched off the celiac trunk of the abdominal aorta and followed a tortuous suprapancreatic route to split into two lobar arteries terminating in the spleen. However, upon closer inspection, a superior polar splenic artery was uncovered with two unique characteristics. Firstly, the presented polar artery lacked branching gastric arteries, a rare variation with a prevalence of only 3.27%. Secondly, the distance between the origin of the superior polar splenic artery and the splenic hilum was greater than what is often reported in clinical literature. While similar previous case reports have observed arterial origins of greater distance, these have often been accompanied by a compensatory arterial length. Interestingly, the case presented in this report contained a superior polar splenic artery with an arterial length shorter than its distance to the splenic hilum, resulting in an atypically taut vessel. This bears clinical importance, as this arterial presentation may be susceptible to a surgical rupture if neglected. By including this anatomical variation in the expanding library of splenic artery variations, surgeons and their collaborative healthcare teams may broaden their understanding of splenic artery anatomy as they conceptualize new techniques for pancreatomy and splenectomy procedures that consider arterial variations while minimizing surgical complications, operative time, and patient blood loss.
