ABSTRACT

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.

ABSTRACT

Thorough knowledge of splenic artery course and morphology may help clinician to provide better practice. This Study aims at finding out if there was a relationship between splenic artery tortuosity index and age, sex, Body Mass Index (BMI) and abdominal cavity diameters. Routine abdominal Computerized Tomography (CT) scan images were retrospectively analyzed for 219 patients. Splenic artery tortuosity index was calculated. Abdominal cavity diameters were measured. Age, sex, and BMI were recorded. Splenic artery straight length (x) mean was 9.41 cm (SD 1.33). Splenic artery tortuous length mean was 15.15 cm (SD 3.31). Splenic artery tortuosity index mean was 1.63 (SD 0.36). Pearson correlation coefficient for Splenic artery tortuosity index vs. age was: 0.02 (P value 0.80). Splenic artery tortuosity index for females vs. males were 1.70 vs. 1.57 (P value 0.01). Pearson correlation coefficient for Splenic artery tortuosity index vs. BMI was 0.02 (P value 0.75). Pearson correlation coefficient for Splenic artery tortuosity index vs. abdominal cavity diameters were: Anterior-Posterior (AP) diameter -0.01 (P value 0.88) and transverse diameter 0.00 (P value 0.98). There may be a relationship between splenic artery tortuosity and female sex, but not with age, BMI and abdominal cavity diameters (AP and Transverse).


El conocimiento del curso y la morfología de la arteria esplénica puede ayudar al médico a proporcionar un diagnóstico y tratamiento oportuno al paciente. Este estudio tuvo como objetivo determinar si existe una relación entre el índice de tortuosidad de la arteria esplénica y la edad, el sexo, el índice de masa corporal (IMC) y los diámetros de la cavidad abdominal. Se tomaron imágenes retrospectivas, de rutina, de 219 pacientes de tomografía computarizada (TC) abdominal. Se calculó el índice de tortuosidad de la arteria esplénica. Se midieron los diámetros de la cavidad abdominal y se registró la edad, sexo y el IMC. La media de la longitud recta de la arteria esplénica (x) fue de 9,41 cm (DE 1,33). La longitud tortuosa de la arteria esplénica fue de 15,15 cm (DE 3,31). La media del índice de tortuosidad de la arteria esplénica fue de 1,63 (DE 0,36). El coeficiente de correlación de Pearson para el índice de tortuosidad de la arteria esplénica vs. edad fue: 0,02 (valor de P 0,80). El índice de tortuosidad de la arteria esplénica para las mujeres frente a los hombres fue de 1,70 frente a 1,57 (valor de P 0,01). El coeficiente de correlación de Pearson para el índice de tortuosidad de la arteria esplénica versus el IMC fue de 0,02 (valor de P 0,75). El coeficiente de correlación de Pearson para el índice de tortuosidad de la arteria esplénica frente a los diámetros de la cavidad abdominal fue: diámetro anterior-posterior (AP) -0,01 (valor P 0,88) y diámetro transversal 0,00 (valor P 0,98). Puede existir una relación entre la tortuosidad de la arteria esplénica y el sexo femenino, sin embargo no se encontró relación con la edad, el IMC y los diámetros de la cavidad abdominal (AP y transversal).

ABSTRACT

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.

ABSTRACT

Introducción: la arteria esplénica es uno de los tres ramos del tronco celiaco que irriga el bazo y emite ramos al estómago y al páncreas. Objetivo: determinar las características morfológicas de la arteria esplénica. Materiales y métodos: se realizó un estudio cuantitativo, longitudinal, prospectivo, observacional y descriptivo, en 26 bloques, provenientes de cadáveres sin cirugías abdominales, ni enfermedades hematológicas, en el Hospital Provincial Universitario "Celia Sánchez Manduley", de Manzanillo, provincia Granma. Los bloques fueron lavados, fijados y disecados por el método macroscópico directo. Resultados: La arteria esplénica se originó, mayormente en el tronco celiaco (88,46 %), su trayecto fue tortuoso en el 84,62 % de los bloques relacionándose por delante de la vena esplénica (80,77 %). Los ramos colaterales fueron más frecuentes en el segmento pancrático (54,96%). Las arterias gástricas cortas fueron los ramos colaterales mayormente emitidos (100 %). La longitud media de la arteria esplénica fue de 14,7 cm y su diámetro medio es de 0,86 cm. El número de arterias terminales tuvo una media de 6,04, mientras que las arterias gástricas cortas se emitieron en una media de 4,76. Conclusiones: la arteria esplénica presenta un patrón de variabilidad anatómica bajo en cuanto a su origen y trayecto, pero sus relaciones, forma de terminación, y ramos colaterales presentan grandes variantes a la norma anatómica (AU).


Introduction: the splenic artery is one of the three of the celiac trunk that irrigates spleen and emits branches to the stomach and the pancreas. Objective: to determine the morphologic characteristics of the splenic artery. Materials and methods: a descriptive, observational, prospective, longitudinal and quantitative study was carried out in 26 tissue samples without abdominal surgeries nor hematologic diseases in the Teaching Provincial Hospital "Celia Sánchez Manduley" of Manzanillo, Granma. The samples were washed, fixed and dissected using the direct macroscopic method. Results: the splenic artery originated, mostly, in the celiac trunk (88.46 %), its itinerary was tortuous in 84.62 % of the samples, linking before the splenic vein (80.77 %). Collateral branches were more frequent in the pancreatic segment (54.96 %). Short gastric arteries were the mostly emitted collateral branches (100 %). The average longitude of the splenic artery was 14.7 cm and its average diameter 0.86 cm. The number of terminal arteries showed an average of 6.04 while the short gastric arteries were emitted in an average of 4.76. Conclusions: the splenic artery has a low anatomic variability pattern according to its origin and itinerary, but its relations, ending form and collateral branches show big variants from the anatomic norm (AU).

ABSTRACT

Splenic artery aneurysms are the most common visceral aneurysm. They are usually asymptomatic, but may present rarely as abdominal pain, or with symptoms and signs of acute rupture. This is a case report of a 42 years old female patient who presented with mild abdominal pain and was found to have a splenic artery aneurysm with a challenging anatomy of the prominent splenic artery. The patient refused the surgical option of treatment, and was treated by endovascular embolization, using a double catheter technique.

ABSTRACT

O aneurisma da artéria esplênica é uma entidade clínica rara, embora seja o mais frequente entre os aneurismas viscerais, sendo encontrado em 0,8 por cento da população. Apresenta-se mais frequentemente em mulheres, na proporção de 4:1, e raramente provoca sintomas ou sinais clínicos. Desenvolve-se de forma assintomática e, na maioria dos casos, é diagnosticado por meio de exames indicados para elucidar queixas clínicas decorrentes de outras doenças ou quando apresenta complicações por vezes fatais, como a rotura. A possibilidade de rotura dos aneurismas de artéria esplênica com diâmetro inferior a 2 cm é baixa; entretanto, os que apresentam diâmetro igual ou maior que 3 cm são usualmente encaminhados para tratamento cirúrgico, devido ao alto risco de rotura. O tratamento eletivo é indicado nos casos não complicados, sendo a embolização com molas um método interessante por evitar o tratamento cirúrgico convencional.


The splenic artery aneurysm is an uncommon clinical entity, but is the most frequent among visceral aneurysms and is present in 0.8 percent of the population. It is more common in women, with a ratio of 4:1, and rarely causes symptoms or signs. It develops asymptomatically and, in most cases, is diagnosed by tests indicated to elucidate clinical complaints subsequent to other diseases or when there are fatal complications such as rupture. The possibility of rupture of splenic artery aneurysms with a diameter less than 2 cm is low; however, those with a diameter equal to or greater than 3 cm are usually referred for surgical treatment due to the high risk of rupture. The elective treatment is indicated for non complicated cases, and the coil embolization is an interesting method, since it avoids conventional surgical treatment.

ABSTRACT

We observed a rare variation of splenic artery during the routine dissection in the Laboratory of the Anatomy Department. It arose from the splenic artery toward the distal part of transverse colon which typically supplied by the inferior mesenteric artery. Embryologically distal part of the transverse colon is a segment of hindgut In this case splenic artery which an artery of foregut supplies an area of hindgut. The knowledge of splenic artery variations has significant importance during surgery of the organs of the upper abdominal region. In this study, we discussed clinical significance and embryological aspects of this anomalous artery

ABSTRACT

A numerical anomaly of the celiac trunk and anatomical variation in origin, and course of the dorsal pancreatic artery were encountered during a routine upper abdomen dissection of a 62-year-old male cadaver. The aim of this study was to describe a rare celiac trunk and dorsal pancreatic artery variation in detail, which can be a guide and precaution during operative procedures in this region. The abdominal aorta, its branches and the pancreas were cut and removed just above the celiac trunk and below the superior mesenteric artery to investigate the vascular distribution of the pancreas in detail. The celiac trunk divided into the left gastric, hepatic, splenic, and dorsal pancreatic arteries. The anatomical variation of the celiac trunk and splenic artery makes it vulnerable to iatrogenic surgery. Knowledge of the existing aberrations is important in planning and conducting surgical procedures

ABSTRACT

Splenic arteriovenous fistula is rare and usually presents with features of established portal hypertension (PHT). Presentation as acute mesenteric ischemia with features of acute PHT is uncommon. We report a 35-year-old lady who presented with severe abdominal pain, diarrhea and ascites, which was found to result from mesenteric ischemia and acute PHT secondary to splenic arteriovenous fistula. She underwent resection of fistula, which resulted in complete symptom relief.

ABSTRACT

Se presenta el caso de un paciente joven con pancreatitis crónica cuya evolución se vio complicada con episodios intermitentes de hemorragia digestiva superior de origen oculto, por el lapso de un año antes de su diagnóstico. La angiografía abdominal demostró la existencia de un pseudoaneurisma de la arteria esplénica, producto de la digestión enzimática de sus paredes. Hubo ruptura de su cavidad hacia el conducto de Winsung lo que explicaba la ausencia de lesiones sangrantes identificables en las repetidas gastroscopias a las que el paciente fue sometido, aunque aparecían coágulos frescos en la segunda porción duodenal. La angiografía permitió, luego de dos sesiones de trabajo, la embolización completa de la cavidad de esta lesión utilizando varios espirales de tungsteno. La fuga distal de uno de estos espirales no tuvo consecuencias. Se hace énfasis en las posibilidades terapeúticas de la Radiología Intervencionista, en estos casos, gracias a la rápida evolución de los materiales disponibles para ello, constituyendo una alternativa válida al tratamiento quirúrgico standart
