ABSTRACT

Introducción: los aneurismas de la arteria esplénica son los más frecuentes de aquellos que asientan en arterias viscerales. La existencia de múltiples aneurismas esplénicos es rara, existiendo pocos casos publicados. Generalmente son asintomáticos y constituyen un hallazgo, es poco frecuente la presentación en nuestra paciente, con dolor inespecífico de hemiabdomen superior. Existen diferentes alternativas terapéuticas, son de primera línea la angio-embolización y colocación de stent endovasculares, tienen como principales limitantes el tamaño del aneurisma y la tortuosidad de la arteria esplénica que dificultan acceso endovascular. El tratamiento quirúrgico queda reservado, para situaciones especiales. Puede realizarse con conservación esplénica (actuando únicamente sobre el aneurisma) o mediante esplenectomía. Descripción de contenido: el video presenta un caso clínico, de aneurismas múltiples de arteria esplénica. El mismo expone presentación clínica, diagnóstico, opciones terapéuticas y la optada en este caso: esplenectomía laparoscópica. Conclusiones: se trata de una entidad poco frecuente, por lo que consideramos fundamental la comunicación del caso. Si bien generalmente constituyen un hallazgo imagenológico, resulta de vital importancia el tratamiento oportuno a fin de prevenir complicaciones graves como la rotura del aneurisma.

Introduction: splenic artery aneurysms are the most frequent kind among aneurysms in visceral arteries. The existence of multiple aneurysms is rather unusual, there being few cases published. In general they constitute findings as they are asymptomatic. The presentation of the patient in the study, with non-specific upper abdominal pain is rather infrequent. Among the different therapeutic options, angio-embolization and the collocation of endovascular stents are the front line approaches, the main limitations being the size of the aneurysm and the tortuous nature of the splenic artery which makes endovascular access difficult. Surgical treatment is reserved for special situations and it May preserve the spleen (only acting on the aneurysm) or may involve a splenectomy. Content description: the video presents a clinical case of multiple splenic artery aneurysms covering clinical presentation, diagnosis and therapeutic options - the chosen one in this case being laparoscopic spenectomy. Conclusions: it is rather an unusual condition, and therefore dissemination of the case is key. Despite their generally being image studies findings, it is of the essence to apply timely therapy to prevent serious complications like the rupture of the aneurysm.

Introdução: os aneurismas da artéria esplênica são os mais comuns nas artérias viscerais. A existência de múltiplos aneurismas esplênicos é rara, com poucos casos publicados. Geralmente são assintomáticos e constituem um achado acidental, sendo rara a apresentação observada na nossa paciente, com dor inespecífica no hemiabdome superior. Existem diferentes alternativas terapêuticas sendo a angioembolização e a colocação de stent endovascular as de primeira linha, suas principais limitações são o tamanho do aneurisma e a tortuosidade da artéria esplênica que dificultam o acesso endovascular. O tratamento cirúrgico é reservado para situações especiais. Pode ser realizada com preservação esplênica (atuando apenas no aneurisma) ou por esplenectomia. Descrição do conteúdo: o vídeo apresenta um caso clínico de múltiplos aneurismas de artéria esplênica. Expõe apresentação clínica, diagnóstico, opções terapêuticas e a escolhida neste caso: esplenectomia laparoscópica. Conclusões: é uma entidade rara, pelo que consideramos essencial a comunicação do caso. Embora geralmente constituam um achado de imagem, o tratamento oportuno é de vital importância para evitar complicações graves, como a ruptura do aneurisma.

ABSTRACT

La hemorragia digestiva determinada por una fístula entre manga gástrica y seudoaneurisma de arteria esplénica o polo superior de bazo es infrecuente. Se presenta un caso clínico de una paciente de 52 años con antecedentes de cirugía de manga gástrica y fuga anastomótica. Ingresó por hemorragia digestiva alta grave. Se operó de emergencia y realizó punto hemostático sobre cara posterior de manga gástrica. Se reintervino por resangrado realizándose la gastrectomía y esplenopancreatectomía distal por solución de continuidad de arteria esplénica. Dada la inestabilidad hemodinámica se efectuó un esofagostoma y yeyunostomía, reconstruyéndose a los 8 meses con buena evolución.


Gastrointestinal bleeding caused by a fistula between the gastric sleeve and a pseudoaneurysm of the splenic artery or upper pole of the spleen is uncommon. A clinical case of a 52-year-old patient with a history of gastric sleeve surgery and anastomotic leak is presented. She was admitted for severe upper gastrointestinal bleeding. She underwent emergency surgery and performed a hemostatic stitch on the posterior face of the gastric sleeve. She underwent reoperation due to rebleeding, performing gastrectomy and distal splenopancreatectomy due to discontinuation of the splenic artery. Given the hemodynamic instability, an esophagostomy and jejunostomy were performed, reconstructing at 8 months with good evolution.


O sangramento gastrointestinal causado por uma fístula entre a manga gástrica e um pseudoaneurisma da artéria esplênica ou pólo superior do baço é incomum. Apresenta-se o caso clínico de um paciente de 52 anos com história de cirurgia de manga gástrica e fístula anastomótica. Ele foi internado por hemorragia digestiva alta grave. Uma operação de emergência foi realizada e um ponto hemostático foi realizado na face posterior da manga gástrica. Foi reoperado por ressangramento, realizando gastrectomia e esplenopancreatectomia distal por descontinuação da artéria esplênica. Dada a instabilidade hemodinâmica, foi realizada esofagostomia e jejunostomia, reconstruindo aos 8 meses com boa evolução.

ABSTRACT

Abstract The spleen is supplied by blood flow through the splenic artery and vein. The purpose of this communication is to report an ectopic spleen supplied only by reverse flow through the left gastro-omental vessels. A 14-year-old boy presented with pelvic splenomegaly supplied only by the left gastro-omental artery and veins connected to the inferior polar vessels, which were the only vessels communicating with the spleen. After detorsion of the spleen and splenopexy, the spleen returned to normal dimensions. The patient had uneventful follow-up. In conclusion, the left gastroepiploic vessels are able to maintain the entire spleen blood supply.


Resumo O baço é suprido pelo fluxo sanguíneo da artéria e veia esplênicas. O objetivo desta comunicação é apresentar um baço ectópico suprido apenas pelo fluxo sanguíneo reverso proveniente dos vasos gastromentais esquerdos. Um paciente de 14 anos apresentou esplenomegalia pélvica suprida apenas por artéria e veia gastromentais esquerdas, conectadas aos vasos polares inferiores, que eram os únicos presentes nesse baço. Após a distorção do baço e a esplenopexia, o baço voltou às dimensões normais. Não houve intercorrências no acompanhamento do paciente. Em conclusão, os vasos gastromentais esquerdos são capazes de suprir o fluxo sanguíneo de todo o baço.

ABSTRACT

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.

ABSTRACT

Resumen Los aneurismas esplénicos verdaderos son dilataciones saculares que involucran todas las capas de la arteria esplénica. Se presentan más frecuentemente en mujeres, en el embarazo y pacientes con hipertensión portal. Son habitualmente asintomáticos y diagnosticados incidentalmente durante el estudio de otra afección abdominal. Hasta un 10% se puede presentar con ruptura, lo que supone un escenario con una alta morbilidad y mortalidad. El tratamiento de los aneurismas esplénicos es aún un tema de controversia y existen variadas modalidades terapéuticas. Presentamos dos casos de pacientes con aneurismas esplénicos: uno de ellos que se manifestó con rotura y el otro por un diagnóstico incidental. Ambos fueron resueltos mediante embolización endovascular con resultados óptimos. Esta modalidad terapéutica poco difundida para el tratamiento de aneurismas esplénicos gigantes o rotos, nos permitió resolver el cuadro de forma segura y efectiva, con mínima morbilidad y mortalidad.


Abstract True splenic aneurysms are saccular dilations of all the layers of the splenic artery, more common in women, pregnancy and portal hypertension. They are usually asymptomatic and diagnosed incidentally during the study of other abdominal diseases. Up to 10% may present with rupture, which implies a high morbidity and mortality. Treatment of splenic aneurysms is still a subject of controversy and there is a great variety of therapeutic modalities. We present two cases of patients with splenic aneurysms: one who presented with rupture and the other one incidentally diagnosed. Both were treated with endovascular embolization achieving optimal results. Although the utility of this therapy has not been assessed for giant or ruptured aneurysms, it allowed us to solve these scenarios in a secure and effective way, with minimum morbidity and mortality.

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

Resumen Introducción: El infarto esplénico ocurre cuando la arteria esplénica o alguna de sus ramas quedan ocluidas, ya sea por émbolos distantes o por trombosis in situ. Dentro de la literatura mundial hay muy pocos casos documentados de infarto esplénico asociado a infección por Citomegalovirus, por lo que este podría considerarse el primero en Colombia. Presentación del Caso: Se trata de una paciente femenina de 53 años quien fue atendida en una institución de tercer nivel de la Ciudad de Bogotá, Colombia, por cuadro de dolor abdominal, a quien se le realizó una tomografía abdominal contrastada que demostró en el bazo una lesión hipodensa en cuña correspondiente con infarto esplénico por lo cual se realizaron estudios complementarios evidenciando como único dato positivo la positividad de la IgM para Citomegalovirus, descartándose eventos de h ipercoagulabilidad. Discusión: El infarto esplénico es una condición infrecuente que normalmente se presenta con síntomas variables e inespecíficos, dentro de las enfermedades infecciosas que corresponden con aproximadamente el 30% de los diagnósticos de Infarto esplénico, la infección por Citomegalovirus únicamente ha sido reportada en muy pocos casos. Se presenta el caso de una mujer joven con infarto esplénico como diagnóstico final de dolor abdominal en quien se descartaron causas de hipercoagulabilidad y se confirma la infección aguda por Citomegalovirus, lo cual se ha descrito muy poco en la literatura y puede considerarse el primer caso reportado en Colombia.


Abstract Introduction: Splenic infarction occurs when the splenic artery or any of its branches are occluded, either by distant emboli or by thrombosis in situ. Within the world literature, there are very few documented cases of splenic infarction associated with Cytomegalovirus infection, so this could be considered the first in Colombia. Case Presentation: This is a 53-year-old female patient who was treated at a third-level institution in the City of Bogotá, Colombia, for symptoms of abdominal pain, who underwent a contrasted abdominal tomography that she demonstrated in the spleen. a hypodense wedge lesion corresponding to splenic infarction, for which reason complementary studies were carried out, showing the positivity of IgM for Cytomegalovirus as the only positive data, ruling out events of hypercoagulability. Discussion: Splenic infarction is an infrequent condition that normally presents with variable and nonspecific symptoms. Among infectious diseases that correspond to approximately 30% of the diagnoses of splenic infarction, Cytomegalovirus infection has only been reported in very few cases. The case of a young woman with splenic infarction is presented as the final diagnosis of abdominal pain in whom causes of hypercoagulability were ruled out and acute infection by Cytomegalovirus was confirmed, which has been described very little in the literature and can be considered the first reported case In colombia.

ABSTRACT

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.

ABSTRACT

Resumen Objetivo: Reportar el caso de un aneurisma gigante de la arteria esplénica de 9,5 cm de diámetro, en una mujer de 75 años de edad, que consultó por síndrome vertiginoso, con hallazgo incidental al examen físico de masa abdominal pulsátil, confirmado mediante angiotomografía de abdomen y pelvis. Materiales y Método: Registro clínico de una paciente sometida a reparación quirúrgica abierta de una aneurisma gigante de la arteria esplénica. Resultados: Mediante laparotomía, abordaje anterior, se efectúa la ligadura del aneurisma con resección parcial del saco aneurismático más esplenectomía, evolucionando sin complicación a 12 meses de seguimiento. Discusión: Se define como aneurisma de la arteria esplénica a toda dilatación mayor a 1 cm de diámetro, presenta indicación quirúrgica cuando mide más de 2 cm y se denomina gigante a partir de los 5 cm. Conclusión: Los aneurismas de la arteria esplénica son una condición infrecuente, habitualmente asintomática, pero potencialmente mortal especialmente en embarazadas; en la literatura solo existen 78 casos reportados de aneurismas gigantes de la arteria esplénica, se recomienda la resolución quirúrgica expedita.


Aim: To report the case of a giant splenic artery aneurysm of 9.5 cm diameter, in a 75 years old woman, who consulted for vertiginous syndrome, with incidental finding to the physical examination of pulsatile abdominal mass, confirmed by angiotomography of abdomen and pelvis. Materials and Method: Clinical record of a patient undergoing open surgical repair of a giant splenic aneurysm. Results: By laparotomy, anterior approach, the ligation of the aneurysm is performed with partial resection of the aneurysm sac plus splenectomy, evolving without complication at 12 months of follow-up. Discussion: The splenic artery aneurysm, is defined at any dilatation greater than 1 cm in diameter, it is surgically indicated when they measure more than 2 cm and called giant from 5 cm. Conclusion: Splenic artery aneurysm is a uncommon condition, usually asymptomatic, but potentially fatal especially in pregnant women, in the literature there are only 78 reported cases of giant splenic artery aneurysms, expedited surgical resolution is recommended.

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

Resumo Aneurismas da artéria esplênica (AAE) verdadeiros são uma patologia rara, mas potencialmente fatal. São o terceiro aneurisma abdominal mais comum, após aneurismas da aorta e da artéria ilíaca, e representam quase todos os aneurismas de artérias viscerais. Os aneurismas verdadeiros são responsáveis ​​por 60% dos AAEs e afetam as mulheres quatro vezes mais do que os homens, geralmente relacionados a uma descoberta incidental ou sintomática aumentada que coincide com o uso da ultrassonografia na gravidez. Em pacientes grávidas, a mortalidade, após a ruptura, é de 65-75%, com mais de 90% de mortalidade fetal. Têm múltiplas etiologias, e acredita-se que as influências hormonais e as alterações do fluxo portal durante a gestação desempenhem um papel importante no desenvolvimento do AAE. Esta revisão discorrerá sobre sua história, epidemiologia, fisiopatologia, diagnóstico, e as técnicas atuais de tratamento.


Abstract True splenic artery aneurysms (SAA) are a rare, but potentially fatal, pathology. They are the third most common type of abdominal aneurysm, after aneurysms of the aorta and of the iliac artery, and account for almost the all aneurysms of visceral arteries. True aneurysms account for 60% of SAA and affect four times as many women as men, generally related to increased incidental or symptomatic findings that coincide with use of ultrasonography in pregnancy. Among pregnant patients, mortality after rupture is 65-75%, with fetal mortality exceeding 90%. There are multiple etiologies and it is believed that hormonal influences and changes in portal flow during gestation play an important role in development of SAA. This review discusses their history, epidemiology, pathophysiology, and diagnosis and current treatment techniques.

ABSTRACT

Resumo Aneurismas de artérias viscerais e renais são raros (0,01 a 2%) e seu risco de ruptura varia entre os diferentes tipos e de acordo com sua anatomia e contexto do paciente (comorbidades, gravidez e histórico de transplante hepático). A mortalidade decorrente da ruptura desses aneurismas é em torno de 25%. Novas técnicas e materiais derivados da neurointervenção parecem alternativas promissoras para o tratamento desses aneurismas. Neste contexto, relatamos um caso de paciente submetida a tratamento endovascular no mesmo procedimento de aneurisma de artéria esplênica e de artéria renal com a utilização de stent Solitaire® (Medtronic, Minneapolis, EUA) e molas de liberação controlada Ruby® (Penumbra, Alameda, EUA). A paciente apresentou boa evolução com ambos aneurismas tratados de forma adequada. Em conclusão, o tratamento endovascular de aneurismas de artéria esplênica e renal no mesmo tempo operatório é exequível e demonstrou segurança e efetividade no caso relatado.


Abstract Visceral and renal artery aneurysms are rare (0.01 to 2%) and their risk of rupture varies between different types and depending on their anatomy and patient context (comorbidities, pregnancy, and liver transplant history). Mortality due to rupture of these aneurysms is around 25%. New techniques and materials derived from neurointervention seem to be promising options for treatment of these aneurysms. In this context, we report the case of a patient undergoing endovascular treatment of both splenic artery and renal artery aneurysms during the same procedure, using Solitaire stents and controlled release coils in both repairs. The patient recovered well with both aneurysms adequately treated. In conclusion, endovascular treatment of splenic and renal artery aneurysms during the same operation is feasible and has proved safe and effective in the case reported.

ABSTRACT

An isolated splanchnic artery injury due to blunt trauma occurs rarely because abdominal vascular injuries are typically associated with injuries to the surrounding abdominal structures, including solid organs or hollow viscus. Of the major abdominal vessels, the celiac artery is the least commonly injured by penetrating or blunt abdominal trauma. Furthermore, a celiac artery dissection due to blunt trauma is rarely reported and there is no clearly defined treatment method, even though endovascular and conservative treatments are accepted widely. On the other hand, endovascular treatment can be challenging if the celiac artery dissection involves its main branch, including the proper hepatic artery, left gastric artery, and splenic artery. This case study presents the treatment experience of a celiac artery dissection involving its main branch following dorsal blunt trauma. Furthermore, conservative treatment is proposed as a treatment option for this rare injury.

ABSTRACT

PURPOSE: This study compared the patency of the splenic vessels between laparoscopic and open spleen and splenic vessel-preserving distal pancreatectomy. METHODS: We retrospectively reviewed a database of 137 patients who underwent laparoscopic (n = 91) or open (n = 46) spleen and splenic vessel-preserving distal pancreatectomy at a single institute from 2001 through 2015. Splenic vessel patency was assessed by abdominal computed tomography and classified into three grades according to the degree of stenosis. RESULTS: The splenic artery patency rate was similar in both groups (97.8 vs. 95.7%, P = 0.779). Also, the splenic vein patency rate was not significantly different between the 2 groups (74.7% vs. 82.6%, P = 0.521). Postoperative wound complication was significantly lower in the laparoscopic group (19.8% vs. 28.3%, P = 0.006), and hospital stay was significantly shorter in the laparoscopic group (7 days vs. 9 days, P = 0.001) than in the open group. Median follow-up periods were 22 months (3.7–96.2 months) and 31.7 months (4–104 months) in the laparoscopic and open groups, respectively. CONCLUSION: Laparoscopic distal pancreatectomy showed good splenic vessel patency as well as open distal pancreatectomy. For this reason, splenic vessel patency is not an obstacle in performing laparoscopic splenic vessel-preserving distal pancreatectomy.

ABSTRACT

In malaria, splenic rupture is a serious complication potentially leading to death. Subcapsular hemorrhage of spleen is thought to be an impending sign of splenic rupture; however, the characteristics of subcapsular hemorrhage are not well known. We report 3 cases of subcapsular hemorrhage of the spleen in vivax malaria, with varying degrees of severity. Case 1 showed subcapsular hemorrhage without splenic rupture, was treated by antimalarial drug without any procedure. The healing process of the patient's spleen was monitored through 6 computed tomography follow-up examinations, over 118 days. Case 2 presented subcapsular hemorrhage with splenic rupture, treated only with an antimalarial drug. Case 3 showed subcapsular hemorrhage with splenic rupture and hypotension, treated using splenic artery embolization. They all recovered from subcapsular hemorrhage without any other complications. These 3 cases reveal the process of subcapsular hemorrhage leading to rupture and a potentially fatal outcome. The treatment plan of subcapsular hemorrhage should be determined carefully considering the vital signs, changes in hemoglobin, and bleeding tendency.

ABSTRACT

Choriocarcinoma is an aggressively growing and widely metastasizing tumor that originates from trophoblastic cells. A primary gastric choriocarcinoma (PGC), however, is very rare. A 76-year-old female patient visited the emergency department of Wonkwang University Hospital with abdominal discomfort and melena. Esophagogastroduodenoscopy revealed a huge ulceroinfiltrative mass lesion with blood clots on the boundary between the greater curvature side and the posterior wall side of the stomach lower body. CT showed a 3-cm exophytic mass lesion with heterogeneous enhancement, an ulcer lesion at the posterior wall side of the stomach lower body, and multiple enlarged lymph nodes at the splenic artery and left gastric artery nodal stations. She underwent a radical subtotal gastrectomy with a D2 lymph node dissection. The final diagnosis was PGC coexisting with adenocarcinoma based on the pathology results. This paper reports a rare case of primary gastric choriocarcinoma coexisting with adenocarcinoma and discusses the characteristics of this neoplasm with reference to the literature.

ABSTRACT

Objectif : Décrire les aspects échographiques des contusions spléniques de l'enfant au CHUP-CDG et rechercher une éventuelle association avec les lésions thoraciques à la radiographie standard.Patients et méthode : Il s'est agi d'une étude descriptive prospective réalisée du 1er Avril 2016 au 30 Novembre 2016. Elle a concerné les enfants âgés de 0 à 14 ans reçus dans le service de radiologie du CHUP-CDG pour contusion abdominale, qui ont présenté des lésions spléniques à l'échographie abdomino-pelvienne et bénéficié de radiographies complémentaires du gril costal gauche. Les caractéristiques sociodémographiques, les circonstances du traumatisme, le délai du diagnostic, les lésions échographiques spléniques, les autres lésions associées et les lésions radiographiques thoraciques. L'analyse des données a été réalisée à l'aide du logiciel de statistique Epi Info version 3.1.Résultats : Seize enfants, 11 garçons et 05 filles ont présenté une contusion splénique. Ils étaient âgés en moyenne de 09 ans, avec des extrêmes de 07 et de 14 ans. Les circonstances de survenue les plus fréquentes étaient constituées par les chutes d'arbre (dans 11 cas) et les accidents de la voie publique (dans 03 cas). L'exploration échographique a montré des contusions spléniques sévères, avec 75% de grade III de l'AAST, associées à un hémopéritoine (chez tous les 16 patients) et à un épanchement pleural (chez un patient). Aucune fracture costale n'a été observée. Conclusion : Les lésions spléniques post traumatiques étaient graves chez la majorité de nos patients mais n'étaient pas associées à des fractures costales. Cette étude préliminaire devrait être poursuivie dans le but d'indiquer ou non une radiographie thoracique complémentaire devant une lésion traumatique grave de la rate à l'échographie

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.
