RÉSUMÉ

SUMMARY: The stomach receives a rich blood supply from five sets of arteries, all of which originate from the celiac trunk. During the dissection of a female cadaver that had been fixed with formalin, an atypical branching pattern was observed. An accessory left gastric artery was found to originate from the left hepatic artery and send small branches to the esophagus, cardia, and fundus of the stomach. However, there was no anastomosis between the lower accessory left gastric artery and the left gastric artery. This is a rare variant of the gastric artery that has not been previously described in detail. It is important to recognize this variation for safe and effective interventional diagnosis and treatment techniques if dealing with the liver or gastric arteries.


El estómago recibe un rico suministro de sangre de cinco conjuntos de arterias, todas las cuales se originan en el tronco celíaco. Durante la disección de un cadáver femenino que había sido fijado con formalina, se observó un patrón de ramificación atípico. Se encontró una arteria gástrica izquierda accesoria que se originaba en la arteria hepática izquierda y enviaba pequeñas ramas al esófago, el cardias y el fondo del estómago. Sin embargo, no hubo anastomosis entre la arteria gástrica izquierda accesoria inferior y la arteria gástrica izquierda. Se trata de una variante rara de la arteria gástrica que no se ha descrito previamente en detalles. Es importante reconocer esta variación para la aplicación de técnicas de diagnóstico y tratamiento intervencionistas seguras y efectivas a nivel del hígado o las arterias gástricas.

RÉSUMÉ

Resumo A síndrome de Dunbar constitui um diagnóstico de exclusão dentro dos quadros de dor abdominal. O tratamento cirúrgico consiste na dissecção completa do ligamento e do gânglio nervoso circundante. Dessa forma, o presente caso refere-se a um paciente do sexo masculino, 45 anos, previamente hígido, com queixa de dor abdominal epigástrica com irradiação para o dorso e fraqueza. Inicialmente, foi realizada tomografia computadorizada de abdome para complementação do quadro, que evidenciou arteriopatia do tronco celíaco e da artéria mesentérica em associação com estenose. Optou-se por tratamento cirúrgico devido à refratariedade da dor, mas os achados foram inespecíficos. Houve necessidade de complementação da propedêutica com angiotomografia seriada para acompanhamento do caso. Após cerca de 6 meses, notou-se espessamento do ligamento arqueado, com compressão do terço proximal do tronco celíaco e estenose de 80%. Em meio a esse cenário, o paciente foi submetido a laparoscopia para descompressão do tronco celíaco, evoluindo satisfatoriamente no pós-operatório.


Abstract Dunbar syndrome is diagnosed by excluding other possible causes of abdominal pains. Surgical treatment comprises complete dissection of the ligament and the surrounding nerve ganglion. This report describes the case of a previously healthy 45-year-old male patient who presented with epigastric abdominal pain irradiating to the back and weakness. Initially, abdominal computed tomography was ordered, showing arteriopathy of the celiac trunk and mesenteric artery with stenosis. The patient underwent surgical treatment because of the refractory pain, but findings were nonspecific. It was necessary to continue workup with serial angiotomography to follow the case. After around 6 months, thickening of the arcuate ligament was found, with compression of the proximal third of the celiac trunk and 80% stenosis. The patient therefore underwent laparoscopy to relieve celiac trunk compression, with satisfactory postoperative recovery.

RÉSUMÉ

Resumen La gastropatía isquémica es una entidad rara, cuya etiología más frecuente es la obstrucción al flujo sanguíneo secundaria a aterosclerosis. Sus manifestaciones clínicas y endoscópicas son inespe cíficas, pudiendo simular afecciones más prevalentes. La sospecha clínica en pacientes con factores de riesgo cardiovascular permite un diagnóstico precoz y tratamiento adecuado. Presentamos el caso de una paciente con gastropatía isquémica crónica que se manifestó con dolor abdominal, pérdida de peso y hallazgos endoscópicos compatibles con linitis plástica. Se arribó al diagnóstico con una biopsia endoscópica en bloque luego de haber obtenido dos biopsias previas no concluyentes.


Abstract Chronic ischemic gastropathy is a rare entity, being the atheroesclerotic vascular the most prevalent cause. Clinical and endoscopic manifestations are unspecific and may simulate more frequent pathologies. Cardio vascular risk factors allow us to diagnose and treat these patients earlier. We present the case of a patient with chronic ischemic gastropathy that manifested abdominal pain, weight loss and endoscopic findings as a simula tor of linitis plastica. The diagnosis was made with an endoscopic block biopsy after two inconclusive biopsies.

RÉSUMÉ

RESUMEN: El tronco celíaco (TC) es la rama de la arteria aorta abdominal (AA) que aporta la irrigación a la porción distal del esófago, parte media del duodeno, al estómago, páncreas, bazo y suple adicionalmente al hígado; sus diferentes expresiones anatómicas son reportadas en los diferentes grupos poblacionales con incidencia variable. Se evaluó las características morfológicas del TC y sus ramas en 26 bloques del piso supramesocólico de cadáveres masculinos adultos no reclamados, del grupo poblacional mestizo, a quienes se les practico autopsia en el Instituto de Medicina Legal de Bucaramanga - Colombia. Se observo el tipo I del TC en 23 especímenes (88,4 %), del cual correspondió 16 muestras (61,5 %). Al subtipo Ia con bifurcación y formación de tronco hepatoesplénico. Hubo un caso (3,8 %) en donde las ramas del T se originaron de manera independiente de la AA. El TC presentó una longitud promedio de 18,6 DE 7,53 mm y un diámetro externo de 7 DE 1,24 mm. De las ramas del TC, la AE presentó un diámetro promedio de 5,89 DE 1,04 mm sin diferencias estadísticamente significativa con relación al diámetro de la AHC, pero si con relación al diámetro de la AGI (P= 0,70; p<0,001 respectivamente). La gran mayoría de la muestra avaluada muestra la presencia de tronco hepatoesplénico seguido de la trifurcación en una verdadera configuración de trípode. El conocimiento de los patrones de ramificación del TC debe ser tomado en cuenta por cirujanos gastroenterólogos, radiólogos intervencionistas y oncólogos para evitar complicaciones durante los procedimientos quirúrgicos abdominales.


SUMMARY: The celiac trunk (CT) is the branch of the abdominal aorta artery (AA) that provides irrigation to the distal portion of the esophagus, the middle part of the duodenum, the stomach, pancreas, spleen and additionally supplies the liver; its different anatomical expressions are reported in the different population groups with variable incidence. The morphological characteristics of the CT and its branches were evaluated in 26 blocks of the supramesocolic floor of unclaimed adult male corpses, of the mestizo population group, who were autopsied at the Institute of Legal Medicine of Bucaramanga - Colombia. Type I CT was observed in 23 specimens (88.4 %), of which 16 samples (61.5 %) corresponded. to subtype Ia with bifurcation and formation of the hepatosplenic trunk. There was one case (3.8 %) in which the branches of the CT originated independently of the AA. The CT had an average length of 18.6 SD 7.53 mm and an external diameter of 7 SD 1.24 mm. Of the CT branches, the splenic artery presented an average diameter of 5.89 SD 1.04 mm without statistically significant differences in relation to the diameter of the AHC, but if in relation to the diameter of the IGA (P = 0.70; p <0.001 respectively). The vast majority of the sample evaluated shows the presence of a hepatosplenic trunk followed by trifurcation in a true tripod configuration. Knowledge of CT branching patterns should be taken into account by gastroenterological surgeons, interventional radiologists, and oncologists to avoid complications during abdominal surgical procedures.

RÉSUMÉ

Abstract We describe a case of unusual development of the celiac trunk observed in the cadaver of 1-year old male child. The celiac trunk branched into five vessels: the splenic, common hepatic and left gastric arteries, the left inferior diaphragmatic artery, and a short trunk that branched into the right inferior diaphragmatic artery and right accessory hepatic artery. Additionally, the manner of branching of the vessel was unusual: it was possible to distinguish two branching points that corresponded to its s-shaped trajectory. There were also other variations of vascular supply, such as the presence of a left accessory hepatic artery, an additional superior pancreatoduodenal artery, and others. It should be noted that multiple developmental variations can be common in clinical practice and clinicians should be aware of them during diagnostic and interventional procedures.


Resumo Apresentamos um relato de caso de desenvolvimento incomum do tronco celíaco em um cadáver do sexo masculino de 1 ano de idade. O tronco celíaco ramificou-se para cinco vasos: as artérias esplênica, hepática comum e gástrica esquerda, a artéria diafragmática inferior esquerda e um tronco pequeno que se ramificou para a artéria diafragmática inferior direita e para a artéria hepática direita acessória. Além disso, a forma como o vaso se ramificou foi incomum: é possível distinguir dois pontos de ramificação que correspondem à trajetória em formato de S. Também houve outras variações do suprimento vascular, como a presença da artéria hepática esquerda acessória, da artéria pancreaticoduodenal superior acessória e outras. Cabe observar que a variação de desenvolvimento múltipla pode ser comum na prática clínica, e os médicos devem estar cientes dela durante os procedimentos de diagnóstico e intervenção.

RÉSUMÉ

SUMMARY: The celiac trunk is the first major unpaired branch of the abdominal aorta found at the twelfth vertebral level (T12). It gives off branches supplying the spleen, liver and the stomach. However, the branching patterns of the celiac trunk tend to vary by population throughout the world. We sought to investigate the branching patterns of the celiac trunk in a South African Caucasian sample. The celiac trunk was assessed by visual observation in 66 dissected bodies comprised of both males (n= 30) and females (n=36). These samples were obtained at the School of Anatomical Sciences, University of the Witwatersrand, Johannesburg. The celiac trunk arose directly from the abdominal aorta in all cases, with none connected to the superior mesenteric artery. We observed celiac trunk trifurcation in 84.84 % of the sample, although a celiac trunk with four branches was observed in 10.61 %. Bifurcation into the common hepatic and splenic arteries forming a hepatosplenic trunk (2 females) or into the left gastric artery and splenic artery forming a splenogastric trunk (1 male) was also observed. The results are largely comparable with other studies in Caucasians, showing a high rate of celiac trunk trifurcation (above 75 %). Our sample exhibited fewer variations than reported in previous studies worldwide. Therefore, a larger study with more samples may be required in the future to ascertain all the existing celiac trunk branching patterns in the South African Caucasian population.


RESUMEN: El tronco celíaco es la primera rama principal de la parte abdominal de la aorta en el nivel de la duodécima vértebra torácica (T12), con ramas que irrigan el bazo, el hígado y el estómago. Sin embargo a nivel mundial, las ramificaciones del tronco celíaco tienden a variar según la población. En este estudio se investigaron los patrones de ramificación del tronco celíaco en una muestra caucásica sudafricana. El tronco celíaco se analizó mediante observación visual en 66 cuerpos disecados compuestos por hombres (n = 30) y mujeres (n = 36). Estas muestras se obtuvieron en la Facultad de Ciencias Anatómicas de la Universidad de Witwatersrand, Johannesburgo. El tronco celíaco surgió directamente de la parte abdominal de la aorta en todos los casos, sin que ninguno estuviera unido a la arteria mesentérica superior. Se observó trifurcación del tronco celíaco en el 84,84 % de la muestra, aunque en el 10,61 % se observó un tronco celíaco con cuatro ramas. También se observó bifurcación en las arterias hepática y esplénica común formando un tronco hepatoesplénico (2 mujeres) o en la arteria gástrica izquierda y la arteria esplénica formando un tronco esplenogástrico (1 hombre). Los resultados son comparables con otros estudios en caucásicos que muestran una alta tasa de trifurcación del tronco celíaco (mayor al 75%). Nuestra muestra presentó menos variaciones que las reportadas en estudios previos. Por lo tanto, es posible que se requieran estudios más amplios con más muestras en el futuro, para determinar todos los patrones de ramificación del tronco celíaco en la población caucásica sudafricana.

RÉSUMÉ

ABSTRACT Background: Median arcuate ligament syndrome(MALS) is a rare condition thatmay cause significant clinical manifestations, including abdominal pain and weight loss. Its diagnosis may be difficult and very often delayed. The laparoscopic approach became the standard treatment of MALS. Aim: To assess the outcome of laparoscopic treatment in patients with MALS. Method: The data of sixpatients with MALS who were subjected to laparoscopic sectioning of the median arcuate ligament were retrospectively reviewed.The following data were evaluated: age, gender, clinical and diagnostic tests findings, ASA score, operative findings and complications, postoperative complications and mortality, hospital stay duration, and hospital readmission.The diagnosis of MALS was established by CT angiography and/or MR angiography. Results: There were four (66.7%) women and two (33.3%) men aged from 32 to 60 years. The main symptoms were epigastric pain (100%) and weight loss (66.7%). The findings of high-grade stenosis of the proximal celiac axis and poststenotic dilation confirmed on angiography confirmed the diagnosis in all patients. Surgical procedure was uneventful in all patients. The only postoperative complication was urinary retention that occurred in a male. At three-month follow-up, all patients were asymptomatic. Conclusion: Laparoscopic treatment of MALS is safe and effective in relieving the clinical manifestations of patients.


RESUMO Racional: A síndrome do ligamento arqueado mediano (SLAM) é condição rara que pode causar manifestações clínicas significativas, incluindo dor abdominal e perda de peso. Seu diagnóstico pode ser difícil e muitas vezes estabelecido tardiamente. A abordagem laparoscópica tornou-se o tratamento padrão para ela. Objetivo: Avaliar o resultado do tratamento laparoscópico em pacientes com SLAM. Método: Os dados de seis pacientes com SLAM submetidos a ressecção laparoscópica do ligamento arqueado mediano foram revisados ​​retrospectivamente. Os seguintes dados avaliados foram: idade, gênero, resultados dosexames clínicos e complementares, escore ASA, achados e complicações operatórias, complicações e mortalidade pós-operatórias, tempo de internação e readmissão hospitalar. O diagnóstico de SLAM foi estabelecido por angiotomografia e/ou angiorressonância. Resultados: Havia quatro (66,7%) mulheres e dois (33,3%) homens com idades entre 32 e 60 anos. Os principais sintomas foram dor epigástrica (100%) e perda de peso (66,7%). Os achados de estenose de alto grau do tronco celíaco proximal e dilatação pós-estenótica observados na angiografia confirmaram o diagnóstico em todos os pacientes. O procedimento cirúrgico transcorreu sem intercorrências em todos os pacientes. A única complicação pós-operatória foi retenção urinária, que ocorreu em um homem. No seguimento de três meses, todos os pacientes estavam assintomáticos. Conclusão: O tratamento laparoscópico da SLAM é seguro e eficaz no alívio das manifestações clínicas dos pacientes.

RÉSUMÉ

INTRODUCCIÓN: El adenocarcinoma de cuerpo y cola de páncreas corresponde a cerca de un tercio del total de cánceres pancreáticos. Evoluciona en forma silenciosa hasta alcanzar estadios avanzados, llegando a comprometer muchas veces grandes vasos como tronco celíaco y sus ramas, y la arteria mesentérica superior. La resolución quirúrgica parece ser la única alternativa en estos casos. OBJETIVO: Presentar dos casos de adenocarcinoma de cuerpo y cola de páncreas tratados en nuestro hospital con pancreatectomía corpo-caudal y resección en bloque de tronco celíaco (procedimiento de Appleby modificado). DISCUSIÓN: Este procedimiento ha demostrado aumentar la sobrevida de estos pacientes, además de generar un alivio inmediato y duradero del dolor. Sin embargo, corresponde a una intervención con una alta morbilidad, siendo la fístula pancreática y la gastropatía isquémica las complicaciones más frecuentes. La evaluación del flujo de los vasos colaterales es un paso crítico para evitar las complicaciones isquémicas. CONCLUSIONES: La pancreatectomía corpo-caudal con resección en bloque de tronco celíaco, es una alternativa factible en adenocarcinoma de cuerpo y cola de páncreas localmente avanzado. Su indicación debe ser cuidadosa debido a que corresponde a un procedimiento con alta morbilidad.


INTRODUCTION: Adenocarcinoma of the body and tail of the pancreas corresponds to about one third of all pancreatic cancers. It evolves silently to reach advanced stages, often involving large vessels such as the celiac trunk and its branches, and the superior mesenteric artery. Surgical resolution seems to be the only alternative in these cases. AIM: To present two cases of adenocarcinoma of the body and tail of the pancreas treated in our hospital with distal pancreatectomy and celiac trunk en block resection (modified Appleby procedure). DISCUSSION: This procedure has been shown to increase the survival of these patients, in addition to generating immediate and lasting pain relief. However, it corresponds to an intervention with a high morbidity, being the pancreatic fistula and the ischemic gastropathy the most frequent complications. The evaluation of the flow of the collateral vessels is a critical step to avoid ischemic complications. CONCLUSIONS: Distal pancreatectomy with en bloc resection of the celiac trunk is a feasible alternative in locally advanced adenocarcinoma of the body and tail of the pancreas. Its indication must be careful since is a procedure with high morbidity.

RÉSUMÉ

RESUMEN: Las variantes anatómicas del tronco celíaco (TC) son relevantes en el ámbito quirúrgico e intervencionista. Existen diferentes estudios a nivel mundial que han demostrado las variaciones que puede presentar el TC tanto en longitud como en estructura; dichos estudios han sido realizados predominantemente en población asiática y europea. Por lo anterior, realizamos un estudio que caracterizó esta estructura y que sea referente para la población mexicana. Se analizó una muestra de 50 especímenes cadavéricos humanos embalsamados de origen mexicano. El promedio de longitud del TC a su primera rama fue de 12,44 mm; de su origen a la segunda rama fue de 17,07 mm; y hasta la tercera fue de 19,15 mm. En la muestra de estudio se encontraron variantes en el 20 % de los especímenes, de éstos el 14 % presentaron variantes morfométricas en cuanto a longitud y 6 % en estructura. Respecto a las variantes morfométricas, destacó la presencia de un TC de 3 mm de longitud. En cuanto a las variantes morfológicas dos individuos presentaron un tronco gastro-esplénico con tronco hepato-mesentérico; y el tercero un tronco bifurcado hepato-gástrico con la arteria esplénica naciendo de la arteria hepática común. Éste último no reportado en la literatura.


SUMMARY: Anatomical variants in the celiac trunk (CT) are important in surgical and interventional fields. Studies worldwide have demonstrated length and structure variations in the celiac trunk. These studies have predominantly been carried out in Asian and European population. Therefore, we considered it necessary to realize a study to describe this structure and serve as a reference in the Mexican population. A sample of 50 human cadaveric specimens of Mexican origin was analyzed. The average length of the celiac trunk from its origin to its first branch was 12.44 mm, to the second branch was 17.07 mm, and to the third branch was 19.15 mm. In the studied sample, variants were found in 20 % of the specimens, 14 % of these presented morphometric variations in terms of length, and 6 % in terms of structure. In reference to the morphometric variants, the presence of one 3 mm length CT was noteworthy. Morphological variants were found in two specimens presenting a gastro-splenic trunk with a hepatomesenteric trunk, and a third specimen with hepatogastric bifurcated trunk, with the splenic artery originating from the common hepatic artery was observed. No reports were found in the literature concerning the latter.

RÉSUMÉ

El estudio de los patrones arteriales de distribución vascular requiere un conocimiento preciso de las variaciones anatómicas, tanto de origen y distribución de las arterias, como de sus correspondientes ramas arteriales. En este trabajo se describe la presencia de un tronco hepato-espleno-mesentérico, disposición arterial altamente infrecuente. El conocimiento de las distintas posibilidades de disposición de las arterias correspondientes al tronco celíaco y sus ramas será de importancia para la interpretación adecuada de estudios imagenológicos, como así también para la planificación precisa de actos quirúrgicos e intervencionistas en la región abdominal.


The study of arterial patterns of vascular distribution requires a precise knowledge of the anatomical variations of both origin and distribution of the corresponding arteries and arterial branches. In this work, the presence of a hepatosplenic-mesenteric trunk is described, a highly infrequent arterial disposition. The knowledge of the different possibilities of disposition of the arteries corresponding to the celiac trunk and its branches will be of importance for the adequate interpretation of imaging studies, as well as for the precise planning of surgical and interventional acts in the abdominal region.

RÉSUMÉ

ABSTRACT Introduction: The celiac trunk (CT) is one of the abdominal portion branches of the aortic artery and, together with the superior mesenteric and inferior mesenteric arteries, participates in the abdominal viscera vascularization through a series of anastomoses. Absence of CT or variation in the number of terminal branches implies in varied abdominal arteries origins, which may have implication in surgical approaches. Objective: To analyze the anatomical variations of the celiac trunk and possible associated surgical clinical implications. Methods: It is a systematic review of articles indexed in the PubMed, Lilacs, SciELO, Springerlink, Scienc Direct and Latindex databases from August to September 2017. Original articles involving the anatomical variations of the celiac trunk in humans were included. The presence/absence of the celiac trunk, the number of terminal branches and the place of origin of its branches in variant cases of the normal anatomical pattern, were considered for this study. Results: At the end of the research, 12 articles were selected, characterized by sample, anatomical structure evaluation method and main results. The normal anatomical pattern was the most prevalent in most studies (75.0%). CT was absent in 41.7% of the findings. The most prevalent anatomical variation was the presence of CT with bifurcation (66.7%). It was also observed the origin of the common and splenic hepatic arteries from the mesenteric arteries (25.0%). The presence of only one branch (16.7%) and quadrifurcation (8.33%) were other findings. Conclusion: CT variations are not uncommon findings, with different anatomic variants being reported. Thus, the importance of knowing the possible variations of this structure is emphasized, which may have implications for surgical interventions and imaging studies related to the abdominal region.


RESUMO Introdução: O tronco celíaco (TC) surge da aorta abdominal e juntamente com as artérias mesentérica superior e mesentérica inferior participa da vascularização de vísceras abdominais por meio de uma série de anastomoses. Ausência do TC ou variação no número de ramos terminais implica em origens variadas das artérias abdominais, o que pode ter implicação em abordagens cirúrgicas. Objetivo: Analisar as variações anatômicas do TC e as possíveis implicações clínico/cirúrgicas associadas. Métodos: Trata-se de uma revisão sistemática de artigos indexados nas bases de dados PubMed, Lilacs, SciELO, Springerlink, Scienc Direct e Latindex, no período de agosto a setembro de 2017. Foram incluídos artigos originais envolvendo as variações anatômicas do TC em humanos. Considerou-se para este estudo a presença/ausência do TC, o número de ramos terminais e o local de origem de seus ramos em casos variantes do padrão anatômico normal. A coleta foi realizada por dois revisores independentes. Resultados: Ao final da busca foram selecionados 12 artigos, caracterizados quanto à amostra, método para avaliar a estrutura anatômica e principais resultados. O padrão anatômico normal foi o mais prevalente na maioria dos trabalhos (75,0%). O TC foi ausente em 41,7% dos achados. A variação anatômica mais prevalente foi a presença do TC com bifurcação (66,7%). Observou-se, ainda, a origem das artérias hepática comum e esplênica a partir das artérias mesentéricas (25,0%). A presença de apenas um ramo (16,7%) e quadrifurcação (8,33%) foram outros achados presentes. Conclusão: Variações do TC não são achados incomuns, sendo relatados diferentes variantes anatômicas. Desse modo, ressalta-se a importância sobre o conhecimento das possíveis variações dessa estrutura, o que pode ter implicação em intervenções cirúrgicas e exames de imagem relacionados à região abdominal.

RÉSUMÉ

We report the first case of a newborn presenting with a celio-mesenteric trunk variation associated with a giant omphalocele. The celio-mesenteric trunk was unexpected and unseen during the staged surgical closure. After partial reintegration of the liver, the newborn presented refractory hypovolemia with anuria, leading to redo surgery. This procedure revealed ischemia of the liver and necrosis of the entire gastrointestinal tract except the colon. Despite treatment, including liver externalization, the infant did not survive. The autopsy revealed a celio-mesenteric trunk, a rare anomaly characterized by a common origin of the celiac axis and the superior mesenteric artery from the aorta. This association may explain the dramatic consequences of the staged closure procedure. Awareness of the association of celio-mesenteric trunk and omphalocele would allow the surgeon to take extra care during this delicate surgery.


Presentamos el primer caso de un recién nacido que presenta una variación del tronco celíaco-mesentérico asociada con un onfalocele gigante. El tronco celíaco-mesentérico fue inesperado y no se vio durante las etapas del cierre quirúrgico. Después de la reintegración parcial del hígado, el recién nacido presentó hipovolemia refractaria con anuria, lo que condujo a la repetición de la cirugía. Este procedimiento reveló isquemia del hígado y necrosis de todo el tracto gastrointestinal excepto el colon. A pesar del tratamiento, incluyendo la externalización hepática, el bebé no sobrevivió. La autopsia reveló un tronco celíaco-mesentérico, una rara anomalía caracterizada por un origen común del tronco celíaco y la arteria mesentérica superior, a partir de la aorta. Esta asociación puede explicar las dramáticas consecuencias del procedimiento durante las etapas del cierre. El conocimiento de la asociación de tronco celíaco-mesentérico y onfalocele permitiría al cirujano tomar especial cuidado durante esta delicada cirugía.

RÉSUMÉ

RESUMEN La disección aislada y espontánea de la arteria celíaca es una entidad clínica rara. Es la cuarta causa de aneurismas abdominales por detrás de los que ocurren en las arterias esplénica, hepática y mesentérica superior. Es importante sospechar el diagnóstico de esta enfermedad cuyos síntomas son inespecíficos. Presentamos el caso de un varón de 60 años de edad atendido en nuestro hospital por esta enfermedad, y hacemos una revisión del tema con énfasis en el diagnóstico y en los diferentes tratamientos disponibles.


SUMMARY Spontaneous and isolated celiac artery dissection is a rare clinical disease. It is the fourth cause of abdominal aneurysms behind those that occur in the splenic, hepatic, and superior mesenteric arteries. It is important to suspect the diagnosis of this entity whose clinical symptoms are unspecific. We report the case of a 60 year-old male treated in our hospital because of this illness, and present a review of this pathology, specially focused on the diagnosis and the different treatments available.


RESUMO A dissecção isolada e espontânea da artéria celíaca é uma entidade clínica rara. É a quarta causa de aneurismas abdominais por detrás dos que ocorrem nas artérias esplénica, hepática e mesentérica superior. É importante suspeitar o diagnóstico desta doença cujos sintomas são inespecíficos. Apresentamos o caso de um homem de 60 anos de idade atendido no nosso hospital por esta doença, e fazemos uma revisão do assunto com ênfase no diagnóstico e nos diferentes tratamentos disponíveis.

RÉSUMÉ

Abstract Anatomical variations of the celiac trunk and its branches are particularly important from a surgical perspective due to their relationships with surrounding structures. We report here a particularly rare variant involving absence of the celiac trunk in association with trifurcation of the common hepatic artery. These variations were found in an adult male cadaver. We perform a review of the literature and discuss the clinical and embryological significance of these variations. Recognition of celiac trunk and hepatic artery variations is of utmost importance to surgeons and radiologists because multiple variations can lead to undue complications.


Resumo As variações anatômicas do tronco celíaco e seus ramos são particularmente importantes do ponto de vista cirúrgico devido a sua relação com as estruturas adjacentes. Nós descrevemos aqui uma variante particularmente rara envolvendo ausência do tronco celíaco associada a trifurcação da artéria hepática comum. Essas variações foram observadas no cadáver de um adulto do sexo masculino. Neste artigo revisamos a literatura e discutimos a significância clínica e embriológica dessas variações. O reconhecimento das variações do tronco celíaco e da artéria hepática é extremamente importante para cirurgiões e radiologistas uma vez que variações múltiplas podem levar a complicações inesperadas.

RÉSUMÉ

We describe the case of a 63-year-old woman with chronic mesenteric ischemia, persistent postprandial upper abdominal pain and progressive weight loss. Retrograde recanalization was performed via the superior mesenteric artery in order to achieve the goal of crossing the near-occlusion, showing that retrograde catheterization of the celiac trunk can be a feasible approach in challenging cases in which an antegrade approach fails as a single maneuver.


Descrevemos o caso de uma mulher de 63 anos de idade, com isquemia mesentérica crônica, dor abdominal pós-prandial e emagrecimento progressivo. A recanalização retrógrada foi realizada através da artéria mesentérica superior para transpassar a estenose crítica. Demonstra-se assim que o cateterismo retrógrado do tronco celíaco pode ser uma abordagem viável em casos difíceis, em que a abordagem anterógrada falha como manobra única.

RÉSUMÉ

Abstract Although digital angiography remains as the gold standard for imaging the celiac arterial trunk and hepatic arteries, multidetector computed tomography in association with digital images processing by software resources represents a useful tool particularly attractive for its non invasiveness. Knowledge of normal anatomy as well as of its variations is helpful in images interpretation and to address surgical planning on a case-by-case basis. The present essay illustrates several types of anatomical variations of celiac trunk, hepatic artery and its main branches, by means of digitally reconstructed computed tomography images, correlating their prevalence in the population with surgical implications.


Resumo Embora a angiografia digital permaneça como padrão ouro no estudo do tronco celíaco e sistema arterial hepático, o exame por tomografia multidetectores associada às ferramentas informáticas de reconstrução de imagens digitais tem representado uma alternativa útil, principalmente por serem métodos não invasivos. O conhecimento detalhado tanto da anatomia normal quanto das variações anatômicas ajuda na interpretação de exames radiológicos e na adequação do planejamento cirúrgico para cada paciente. Este texto ilustra uma série de variações anatômicas do tronco celíaco e sistema arterial hepático, por meio de imagens tomográficas com reconstruções digitais, correlacionando as prevalências populacionais e implicações cirúrgicas.

RÉSUMÉ

Abstract Objective: To analyze the prevalence of anatomical variations of celiac arterial trunk (CAT) branches and hepatic arterial system (HAS), as well as the CAT diameter, length and distance to the superior mesenteric artery. Materials and Methods: Retrospective, cross-sectional and predominantly descriptive study based on the analysis of multidetector computed tomography images of 60 patients. Results: The celiac trunk anatomy was normal in 90% of cases. Hepatosplenic trunk was found in 8.3% of patients, and hepatogastric trunk in 1.7%. Variation of the HAS was observed in 21.7% of cases, including anomalous location of the right hepatic artery in 8.3% of cases, and of the left hepatic artery, in 5%. Also, cases of joint relocation of right and left hepatic arteries, and trifurcation of the proper hepatic artery were observed, respectively, in 3 (5%) and 2 (3.3%) patients. Mean length and caliber of the CAT were 2.3 cm and 0.8 cm, respectively. Mean distance between CAT and superior mesenteric artery was 1.2 cm (standard deviation = 4.08). A significant correlation was observed between CAT diameter and length, and CAT diameter and distance to superior mesenteric artery. Conclusion: The pattern of CAT variations and diameter corroborate the majority of the literature data. However, this does not happen in relation to the HAS.


Resumo Objetivo: Analisar a prevalência de variações anatômicas da ramificação do tronco arterial celíaco (TAC) e do sistema arterial hepático (SAH), o diâmetro e comprimento do TAC e sua distância para a artéria mesentérica superior. Materiais e Métodos: Estudo retrospectivo, transversal, predominantemente descritivo, baseado na análise de imagens de tomografia computadorizada de 60 pacientes. Resultados: A anatomia do TAC foi normal em 90% dos casos. Cinco (8,3%) pacientes apresentaram o tronco hepatoesplênico e um (1,7%) apresentou o tronco hepatogástrico. O SAH variou em 21,7% dos casos. Desses, 8,3% foram na localização anômala da artéria hepática direita e 5% da artéria hepática esquerda. Ainda foram encontrados 3 (5%) casos de relocalização conjunta da artéria hepática direita e artéria hepática esquerda e 2 (3,3%) de trifurcação da artéria hepática própria. A média de comprimento e o calibre médio do TAC foram, respectivamente, 2,33 cm e 0,8 cm. A distância média entre o TAC e a artéria mesentérica superior foi 1,2 cm, com desviopadrão de 4,08. Houve correlação significativa entre diâmetro e comprimento do TAC, e diâmetro do TAC e distância deste para a artéria mesentérica superior. Conclusão: O padrão de variação do TAC e seu diâmetro corroboram a maioria dos dados da literatura, embora o mesmo não tenha ocorrido em relação ao SAH.

RÉSUMÉ

El síndrome del ligamento arcuato medio (SLAM), o síndrome de compresión del tronco celíaco, es causado por la compresión extrínseca del ligamento arcuato medio, bandas fibrosas prominentes y tejido ganglionar periaórtico. En muchas ocasiones es asintomático, pero puede manifestarse con síntomas como dolor abdominal postprandial o durante el ejercicio, náuseas, vómitos y pérdida de peso. Mediante técnicas poco invasivas, como la ecografía doppler color y la angiotomografía preoperatoria, es posible obtener resultados diagnósticos comparables a los de la arteriografía. La cirugía constituye el tratamiento de elección, siendo la vía laparoscópica una técnica segura y eficaz Se presenta un caso sintomático atípico que requirió tratamiento quirúrgico laparoscópico, con mejoría clínica e imagenológica luego del procedimiento.


Median arcuate ligament syndrome (MALS), or celiac trunk compression syndrome, is caused by extrinsic compression of median arcuate ligament, prominent fibrous bands and periaortic nodal tissue. In many cases is asymptomatic, but it may manifests with symptoms such as postprandial abdominal pain or during exercise, nauseas, vomiting and weight loss. Trough less invasive diagnostic techniques, such as doppler ultrasound for screening and preoperative angiotomograhpy, it is possible to obtain good results, comparable to those with arteriography. Surgical treatment by laparoscopic approach is a safe and effective technique. A symptomatic case that required surgical treatment, a laparoscopic approach, with clinical and imaging improvement after the procedure, is presented.

RÉSUMÉ

An exhaustive knowledge of the liver vascular patterns as well as possible anatomical variations is significant in the planning and performance of all liver surgical procedures in order for the vascularity not to be disturbed or not causing necrosis of the liver parenchyma postoperatively. The celiac trunk usually provides three branches; left gastric, splenic and common hepatic arteries. The left and right hepatic arteries generally derive from proper hepatic artery which is a branch of common hepatic artery. To study the incidence of celiac trunk ramification, the branching patterns of the celiac trunk of 23 Thai cadavers (17 males, 6 females) were documented during routine dissection by medical students at the Department of Anatomy, Faculty of Medical Science, Naresuan University, Thailand. The clinically important variations of the celiac trunk were noted. The results showed that all celiac trunks arose from each aortas at the T12 vertebra (17.39%, 4 cases), intervertebral disc between T12 and L1 vertebra (78.26%, 18 cases) and upper 1/3rd of L1 vertebra (4.35%, 1 case). We found 95.65% (22 cases) normal celiac trunk trifurcation; whereas, 4.35% (1 case) was abnormal quadrifurcation of the trunk. The accessory hepatic artery (aHA) was presented as an additional branch of celiac trunk because the conventional pattern of the left and right hepatic arteries was presented. This finding is one of the rare anatomical variations which is reported in available literatures. The awareness of celiac trunk and its stems aberrant is important in procedures such as liver transplant for appropriate vascular ligation and anastomosis.


Un conocimiento exhaustivo de los patrones vasculares del hígado, así como sus posibles variaciones anatómicas son importantes en la planificación y realización de todos los procedimientos quirúrgicos hepáticos para evitar comprometer la vascularización y posible necrosis del parénquima después de la cirugía. El tronco celíaco, por lo general, proporciona tres ramas: gástrica izquierda, esplénica y arteria hepática común. Las arterias hepáticas izquierda y derecha en general derivan de la arteria hepática propia, que es una rama de la arteria hepática común. El objetivo de este trabajo fue estudiar la incidencia de distribución del tronco celíaco mediante la documentación de patrones de ramificación en 23 cadáveres de Tailandia (17 hombres y 6 mujeres). El estudio se efectuó durante la disección de rutina realizada por los estudiantes de medicina en el Departamento de Anatomía de la Facultad de Ciencias Médicas, Universidad de Naresuan, Tailandia. Se observaron las variaciones clínicamente importantes del tronco celíaco. Los resultados mostraron que todos los troncos celíacos surgieron desde la aorta a nivel de la vértebra T12 (17,39%, 4 casos), a nivel del disco intervertebral entre T12 y L1 vértebra (78,26%, 18 casos) y a nivel del tercio superior de la vértebra L1 (4,35%, 1 caso). Encontramos un 95,65% (22 casos) de troncos celíacos normales, es decir, con trifurcación; mientras que un 4,35% (1 caso) era anormal, con 4 ramos terminales. La arteria hepática accesoria (AHA) se presentó como una rama accesoria del tronco celíaco, ya que existía un patrón convencional de las arterias hepáticas izquierda y derecha. Este hallazgo representa una de las raras variaciones anatómicas informada en la literatura. El conocimiento del tronco celíaco y sus ramas aberrantes son importantes en procedimientos como el trasplante hepático, la anastomosis y una ligadura vascular adecuada.
