Causa rara de dolor abdominal recurrente; coexistencia del síndrome de Wilkie y el síndrome del cascanueces / A rare cause of recurrent abdominal pain; the coexistence of Wilkie's syndrome and nutcracker syndrome

El síndrome del cascanueces es un síndrome que presenta síntomas clínicos como hematuria, proteinuria ortostática, congestión pélvica, varicocele del lado izquierdo, hipertensión y dolor en fosa renal. Estos síntomas se producen por la compresión de la vena renal izquierda entre la aorta y la arteria mesentérica superior. En el síndrome de Wilkie, la tercera porción del duodeno está comprimida entre la arteria mesentérica superior y la aorta abdominal, lo que provoca diversos síntomas gastrointestinales. La coexistencia de estos dos síndromes constituye una afección rara y se incluye como casos clínicos en la bibliografía. En este artículo, se presentan los resultados clínicos y radiológicos de un paciente de 17 años que presentaba dolor abdominal recurrente debido al síndrome de Wilkie, acompañado del síndrome del cascanueces que le provocaba proteinuria, por lo que el paciente fue derivado a los consultorios externos de reumatología pediátrica con un diagnóstico preliminar de fiebre mediterránea familiar.

Nutcracker syndrome is a syndrome that has clinical symptoms such as hematuria, orthostatic proteinuria, pelvic congestion, left-sided varicocele, hypertension, and flank pain. These symptoms occur because of the compression of the left renal vein between the aorta and the superior mesenteric artery. In Wilkie's syndrome, the third part of the duodenum is compressed between the superior mesenteric artery and the abdominal aorta, causing various gastrointestinal symptoms. The coexistence of these two syndromes is a rare condition and is included as case reports in the literature. This article presents the clinical and radiological results of a 17-year-old male patient who had recurrent abdominal pain due to Wilkie's syndrome, which was accompanied by nutcracker syndrome that caused proteinuria, and for this reason, the patient was referred to the Pediatric Rheumatology outpatient clinic with a preliminary diagnosis of familial Mediterranean fever.

Síndrome de Wilkie: caso clínico / Wilkie syndrome: case report

Resumen Introducción: El síndrome de Wilkie es una causa poco frecuente de obstrucción del tracto digestivo superior, se caracteriza por una disminución del ángulo aorto-mesentérico que resulta en compresión de la tercera porción del duodeno que produce síntomas obstructivos altos. Caso Clínico: Presentamos el caso de una mujer de 64 años, con historia de dolor abdominal, pirosis, saciedad precoz e intolerancia a la vía oral, en quien los estudios iniciales mostraron esofagitis, pero en quien los síntomas no mejoraron con el tratamiento clásico para enfermedad ácido péptica y en quien estudios imagenológicos adicionales sugerían el síndrome de Wilkie como causa de los síntomas. Discusión y Conclusión: Se trata de una patología que debe conocerse y considerar en paciente con historia de pérdida de peso, marcada intolerancia a la vía oral y falta de respuesta al manejo.

Introduction: Wilkie syndrome is a rare cause of upper gastrointestinal tract obstruction, it is characterized by a decrease in the aorto-mesenteric angle that results in a compression of the third portion of the duodenum causing high obstructive symptoms. Case Report: We present the case of a 64-year-old woman, with a history of abdominal pain, heartburn, early satiety, and intolerance to the oral route, in whom initial studies showed esophagitis, but in whom symptoms did not improve with the classic treatment for peptic acid disease, additional imaging studies suggested Wilkie syndrome. Discussion and Conclusión: It is a pathology that must be known and suspected in patients with a history of weight loss, marked intolerance to oral intake, and lack of treatment response.

Superior Mesenteric Artery Syndrome - An Uncommon Complication After Surgical Corrections of Spinal Deformities / Síndrome da artéria mesentérica superior - Uma complicação incomum após correções cirúrgicas de deformidades da coluna

Abstract Vascular compression of the third part of the duodenum by the superior mesenteric artery results in an unusual occlusion of the duodenal transit known as superior mesenteric artery syndrome. This syndrome can occur after surgeries to correct spinal deformities in a rate ranging from 0.5% to 4.7%. It results from a positional alteration of the artery emergency point due to a change in trunk length after surgery. It is associated with risk factors such as low body mass index and weight loss. Patients usually present with intestinal occlusion, abdominal pain, nausea, bilious vomiting, and early satiety. Superior mesenteric artery syndrome must be recognized early to institute an adequate treatment, which can be clinical (with gastric tube for decompression and nutritional support) or require a surgical procedure. Secondary complications related to superior mesenteric artery syndrome include delayed surgical and nutritional recovery, healing problems, and prolonged hospitalization. The present study aims to report a case of superior mesenteric artery syndrome in a patient with neuromuscular scoliosis secondary to a transverse myelitis who underwent surgical treatment for spinal deformity correction.

Resumo A compressão vascular da terceira parte do duodeno pela artéria mesentérica superior resulta no desenvolvimento de uma condição incomum de oclusão do trânsito duodenal conhecida como síndrome da artéria mesentérica superior. Este fenômeno pode acontecer após cirurgias de correção de deformidades da coluna, e sua taxa de ocorrência é de 0,5 a 4,7% dos casos. Isso ocorre em virtude da alteração do posicionamento do ponto de emergência da artéria, decorrente da mudança do comprimento do tronco após a cirurgia, e está associado a fatores de risco, como baixo índice de massa corpórea e perda ponderal. Os pacientes costumam se apresentar com um quadro de oclusão intestinal, com dor abdominal, náusea, vômito bilioso e saciedade precoce. O reconhecimento desta condição é importante para instituir o tratamento adequado, que varia do tratamento clínico, com sondagem e descompressão gástrica associados a suporte nutricional; à necessidade de abordagem cirúrgica. Complicações secundárias relacionadas à síndrome da artéria mesentérica superior incluem: recuperação cirúrgica e nutricional retardadas, problemas com a cicatrização e hospitalização prolongada. O objetivo do presente estudo é relatar um caso de síndrome da artéria mesentérica superior, ocorrido em um paciente com escoliose neuromuscular secundária a sequela de mielite transversa, submetido ao tratamento cirúrgico da deformidade da coluna.

RESUMEN El síndrome de Wilkie o de arteria mesentérica superior es una causa poco común de obstrucción intestinal proximal, relacionada a pérdida de peso reciente. Reportamos el caso de una mujer de 19 años que se presenta a la clínica con pérdida de peso, dolor abdominal, nausea y vomito. Los exámenes de laboratorio reportaron anemia, hipoalbuminemia, hipomagnesemia y una hormona estimulante de la tiroides suprimida secundario al uso con levotiroxina. Se realizó una serie esofagogastroduodenal con datos compatibles con dilatación gástrica severa, gastroparesia y una tomografía axial computada reveló un ángulo aortomesentérico de 11,7°. Se inicio manejo conservador a base de nutrición enteral y parenteral total, siendo este el tratamiento de elección. En casos refractarios, la cirugía es una opción segura y efectiva.

ABSTRACT Wilkie's syndrome or superior mesenteric artery syndrome is an unusual cause of proximal intestinal obstruction, primarily attributed to recent weight loss. We report the case of a 19-year-old woman comes to our clinic and reports weight loss, abdominal pain, nausea, and vomiting. Laboratory tests revealed anemia, hypoalbuminemia, hypomagnesemia, and a suppressed thyroid stimulating hormone secondary to levothyroxine. A barium swallow test showed gastric dilatation, delayed gastric emptying and an axial computed tomography revealed an aortomesenteric angle of 11.7°. Conservative management with total parenteral and enteral nutrition was initiated, being the first-line treatment. In refractory cases surgery is a safe and effective option.

ABSTRACT Superior mesenteric artery syndrome or "Wilkie syndrome" is a very rare entity, characterized by significant weight loss and vomiting of partially digested food. The diagnostic suspicion is based on the presence of predisposing and/or risk factors. Imaging studies such as serial esophagogastroduodenum and Doppler ultrasound allow its confirmation. The primary treatment is supported by adequate nutrition. Following the failure of medical treatment, surgical management is indicated with different techniques to resolve the occlusion. We present the case of a teenager with chronic gastroduodenal occlusion, failure in medical treatment and surgical resolution with good results.Keywords: Superior mesenteric artery syndrome; duodenal obstruction; duodenogastric reflux; laparotomy; anastomosis, surgical; gas-troparesis

Tratamento cirúrgico da síndrome da artéria mesentérica superior em paciente idosa / Surgical treatment of mesenteric superior artery syndrome in an older woman

A síndrome da artéria mesentérica superior (SAM), ou síndrome de Wilkie, é uma afecção rara que acomete geralmente indivíduos jovens do sexo feminino. Caracterizada pela obstrução parcial ou completa do duodeno devido à compressão pela artéria mesentérica superior anteriormente, e pela aorta, posteriormente. Apresentamos um caso não usual de SAM, em paciente idosa, diagnosticado através de história clínica e imagem tomográfica característica. Indicou-se manejo cirúrgico de derivação jejunal e anastomose com duodeno acima da obstrução, na ciência do risco do procedimento. A paciente apresentou excelente evolução e encontra-se assintomática. O diagnóstico precoce, através de uma anamnese adequada e uso dos critérios radiológicos já definidos em literatura, podem afetar positivamente o desfecho dos pacientes portadores em qualquer faixa etária. (AU)

Superior mesenteric artery syndrome (SMAS), or Wilkie syndrome, is a rare condition that usually affects young women. It is characterized by partial or complete obstruction of the duodenum due to compression by the superior mesenteric artery anteriorly and by the aorta posteriorly. We report an unusual case of SMAS in an older woman diagnosed using clinical history and tomographic imaging. Surgical management consisting of jejunal shunt and anastomosis with duodenum above the obstruction was indicated despite the risk of the procedure. The outcome was excellent, and the patient is asymptomatic. Early diagnosis using adequate anamnesis and radiological criteria defined in the literature may positively influence the outcome of patients from any age group. (AU)

Síndrome de la arteria mesentérica superior en una adolescente de 12 años. Caso clínico / Superior mesenteric artery syndrome in a 12-year-old adolescent. Clinical case

El síndrome de la arteria mesentérica superior es una enfermedad poco frecuente en pediatría. Se produce por la compresión de la tercera porción duodenal a su paso entre la arteria mesentérica superior y la aorta abdominal (compás aortomesentérico). La mayoría de los pacientes presentan factores predisponentes:pérdida de peso aguda o compresiones extraabdominales.Se presenta el caso de una niña de 12 años de edad a quien se le diagnosticó el síndrome sin presentar factores predisponentes.Comenzó de modo súbito con náuseas, vómitos incoercibles y dolor abdominal, que era posprandial y se aliviaba, llamativamente, en decúbito lateral izquierdo. Esto constituyó la sospecha clínica del síndrome, por lo que se solicitó una angio tomografía computada abdominal y se observó el estrechamiento del compás aortomesentérico. Se realizó un tratamiento médico conservador, sin respuesta clínica. Se decidió el tratamiento quirúrgico y se logró la resolución del cuadro clínico

The superior mesenteric artery syndrome is rarely seen in children. It results from an intestinal obstruction due to compression of the third portion of duodenum between the superior mesenteric artery and the abdominal aorta. In most of the cases there are predisposing factors such as rapid weight loss or extra-abdominal compression.We report a case of a superior mesenteric artery syndrome in a twelve-year-old female patient without predisposing factors. The girl began suddenly with nauseas, continuous vomiting and abdominal pain. The abdominal pain was postprandial and it decreased in left lateral decubitus position. Clinically, this characteristic suggested superior mesenteric artery syndrome. Angio-computed tomography scan confirmed the diagnosis. Given that conservative treatment ultimately failed, patient was subjected to surgery and the illness was resolved.

Tratamiento mínimamente invasivo del síndrome de Wilkie / Minimally invasive management of Wilkie´s syndrome

Introducción. La compresión de la tercera porción del duodeno debido a la formación de un ángulo inadecuado de la unión aortomesentérica, se configura como el síndrome de arteria mesentérica superior o síndrome de Wilkie. Se trata de una entidad rara, de modo que es escaso su reporte en la literatura y poco aplicado su manejo quirúrgico mínimamente invasivo. Materiales y métodos. Se hace una revisión no sistemática de la literatura y posteriormente se expone el caso de un paciente con síndrome de Wilkie. Se muestran las imágenes de tomografías y un vídeo del procedimiento quirúrgico al que fue sometido. Discusión. El tratamiento quirúrgico del síndrome de la arteria mesentérica superior es el último recurso que se ofrece en pacientes con esta entidad. La duodenoyeyunostomía es el procedimiento con mejor evidencia en pacientes con compromiso severo del estado nutricional. Se describen los puntos esenciales de esta técnica utilizada en el caso que se reporta. Conclusiones. Cualquier entidad que cause la disminución del paquete graso entre la arteria mesentérica superior y la aorta puede causar síndrome de la arteria mesentérica superior. El diagnóstico es de exclusión y constituye un reto para el equipo médico. El tratamiento inicial es conservador, en tanto que la última opción es el manejo quirúrgico, idealmente por vía laparoscópica. Dentro de las técnicas mínimamente invasivas, la duodenoyeyunostomía es una buena herramienta

Introduction: Compression of the third portion of the duodenum due to an inappropriate angle of the aortamesenteric junction is known as the superior mesenteric artery syndrome or Wilkie's syndrome. A rare entity, reason why the reports in the literature are scarce and the minimally invasive surgical management is scarcely used. Materials and methods: A non-systematic review of the literature was carried out, and the case of a patient with Wilkie's syndrome is reported. The images, tomographies and a video of the surgical procedure are presented.Discussion: The surgical management of the superior mesenteric artery syndrome is the ultimate management to be offered in patients with this entity. Duodenojejunostomy is the procedure with the best evidence to be offered to patients with severe malnutrition. The essential points of this technique, used for the case reported, are described. Conclusions: Any entity that causes the reduction of the fatty pack between the superior mesenteric artery and the aorta can cause superior mesenteric artery syndrome. The diagnosis is made by exclusion and constitutes a challenge for the medical team. The initial treatment is conservative, and the last option is the surgical management, ideally laparoscopic; among the minimally invasive techniques, duodenojejunostomy is a good tool

Síndrome pinzamiento mesentérico: a propósito de un caso de hiperemesis / Superior mesenteric aartery syndrome: in relation to a case of hypermesis

INTRODUCCIÓN: El Síndrome de Arteria Mesentérica (SAMS) o Pinzamiento Mesentérico es un trastorno adquirido poco frecuente. Su característica principal es la obstrucción de origen vascular de la tercera porción duodenal, entre la arteria mesentérica superior y la aorta abdominal. CASO CLÍNICO: Mujer de 42 años de edad con antecedentes de trastorno depresivo, colecistectomizada en 1994 y múltiples hospitalizaciones por hiperemesis desde 1995 con estudios no concluyentes. Ingresó en diciembre de 2011 por vómitos alimentarios, con gran compromiso nutricional. Se le realizaron múltiples estudios que descartaron enfermedades reumatológicas, hepáticas e infecciosas. Entre los estudios imagenológicos, la endoscopía digestiva alta mostró esofagitis congestiva leve y gastritis crónica antral, al igual que todas las endoscopias previas. En la radiografía seriada esófago-gastroduodenal se observa severo reflujo gastroesofágico,y compresión compatible con pinzamiento. La tomografía computarizada de abdomen y pelvis mostraba el estómago de mayor tamaño que lo habitual y el duodeno presentaba nuevamente esta compresión compatible con pinzamiento. En base a estos últimos hallazgos imagenológicos, y luego de descartar variados diagnósticos diferenciales se planteó un SAMS y se decidió realizar bypass duododenoyeyunal, con buena evolución posterior. DISCUSIÓN: El diagnostico de SAMS es muchas veces de exclusión, basado en la clínica y la imagenología abdominal que descarta otros cuadros clínicos. En este caso se tiene el antecedente de múltiples hospitalizaciones sin diagnóstico concluyente. Finalmente por la larga evolución del cuadro se decide una resolución quirúrgica.

INTRODUCTION: The Superior Mesenteric Artery Syndrome (SMAS) is an uncommon acquired disorder. The main characteristic is the obstruction due to compression of the third portion of the duodenum, between the superior mesenteric arthery and the abdominal aorta. CLINICAL CASE: 42-year-old female patient with a record of depressive disorder, cholecystectomyperformed in 1994 and multiple hospitalizations due to hyperemesissince 1995, with inconclusive studies. Was admitted to the hospital on December 2011 because to alimentary vomit associated with great nutritional compromise. Multiple exams were performed to discard rheumatologic, hepatic and infectious diseases. The imaging test showed high digestive endoscopy with mild esophagitis and antral chronic gastritis, as in previous endoscopies. Stomach-esophagus-duodenum radiography with gastroesophageal reflux and extrinsic compression of the duodenum. Abdominal and pelvic computed tomography revealed a larger than usual stomach’s size and a compression in the duodenum compatible with pinching. Based on these last results and after we discard other options, we diagnosed a superior mesenteric artery syndrome and it was decided to perform a duodenojejunal bypass, with favorable evolution. DISCUSSION: The diagnosis of SMAS many times is made by exclusion based on the clinic and the abdominal images, discarding other pathologies. In this case, multiple hospitalizations with inconclusive diagnostics led to performing several tests for a variety of illnesses. Finally, based on the large evolution of the case it was decided a surgical resolution.

Síndrome da artéria mesentérica superior: relado de caso / Superior mesenteric artery syndrome: a case report

A síndrome da artéria mesentérica superior é uma condição incomum de obstrução duodenal secundária à compressão extrínseca pela artéria mesentérica superior. Este estudo tem por objetivo apresentar um caso de síndrome da artéria mesentérica superior após cirurgia plástica. Paciente do sexo feminino, 43 anos, deu entrada na emergência apresentando dor abdominal, náuseas, vômitos e distensão abdominal após cirurgia de lipoaspiração e implante de prótese mamária. Uma tomografia computadorizada de abdome revelou distensão da câmara gástrica e duodeno proximal, com compressão abrupta desta porção pela passagem da artéria mesentérica superior, levando a um clampeamento aorto-mesentérico. O diagnóstico de síndrome da artéria mesentérica superior foi confirmado e indicado o tratamento cirúrgico. A paciente foi submetida à cirurgia e anastomose duodenojejunal. O curso pós-operatório ocorreu sem anormalidades e a paciente recebeu alta hospitalar sem complicações. Diante de pacientes com estas características, a síndrome da artéria mesentérica superior deve ser suspeitada. O tratamento cirúrgico deve ser indicado e os resultados são satisfatórios.

Superior mesenteric artery syndrome is an uncommon condition of duodenal obstruction secondary to external compression by superior mesenteric artery. The aim of this study is to report a case of superior mesenteric artery syndrome after plastic surgery. A 43-year-old woman presented with abdominal pain, nausea, vomiting and abdominal distention after liposuction and breast implant. A computed tomography showed a distention of stomach and proximal duodenum, with an abrupt compression of this portion by the crossing of the superior mesenteric artery, leading to an aortic mesenteric clamping. The diagnosis of superior mesenteric artery syndrome was made and the surgical treatment indicated. The patient underwent duodenojejuno anastomosis. The postoperative course was uneventful and was discharged from the hospital without complications. The superior mesenteric artery syndrome should be suspected in patients with signs of high duodenal obstruction and weight loss. The surgical treatment is indicated and the results are satisfactory.

Wilkie’s syndrome: review of eight cases / Wilkie’s syndrome: review of eight cases.

BACKGROUND: The superior mesenteric artery (SMA) syndrome is a rare entity presenting with upper gastrointestinal tract obstruction and abrupt weight loss. Usually seen in tall individual with low bod mass index (BMI), the weight loss may be primary or secondary to a systemic disease or to the syndrome itself Compression of the duodenum between the abdominal aorta and the superior mesenteric artery due to loss of the duodenal pad of fat causes the obstruction. Early recognition prevent complications. Imaging and endoscopy is diagnostic. Aorto-mesenteric angle and SMA aorta distance is lower than 22 degree and eight millimeter respectively. If nutritional support fails, surgery is required (e.g. guodeno-jejunostomy). Studies to determine the optimal methods of diagnosis and treatment, especially in a suburban hospitals with limited expertise are essential. CASE REPORT: We retrospectively evaluated 8 cases presented over three years. Six (75

) patients were males, age ranged from 19 to 70 years and weight from 40 to 55 kg. The mean BMI was 18.7 kg/ m2 (range 16.42 to 25.11 kg/m2). Mean weight loss before diagnosis was 9.88 kg (range 6 to 12 kg). Symptoms developed between 8 to 180 days (median 12 days). Commonest presentation was epigastric pain, vomiting and nausea. Four patients had pre-morbid conditions and the syndrome was idiopathic in the other 4. Median aorto-mesentric angle was 16.5 degree and SMA-aorta distance was 5.15 mm. Four patients required operation. The rest improved on conservative treatment. CONCLUSION: Early recognition, institution of the appropriate conservative measures and timely selection of a definite surgical method are critical to prevent severe complications and death.

Síndrome da artéria mesentérica superior: relato de caso / Superior mesenteric artery syndrome: case report

A síndrome da artéria mesentérica superior (SAMS) ou síndrome de Wilkie é uma afecção rara, caracterizada pela obstrução parcial ou completa da terceira porção do duodeno pela artéria mesentérica superior na face anterior, e pela aorta e coluna vertebral posteriormente. Apresentamos o caso de uma paciente que evoluiu no pós-operatório de colecistectomia com vômitos incoercíveis, pós-prandiais, não melhorados com antieméticos, sendo diagnosticado SAMS na avaliação complementar. Como paciente não apresentou resposta ao tratamento clínico, foi optado pelo tratamento cirúrgico. Atualmente sem complicações até o seguimento ambulatorial de 18 meses. A SAMS é uma causa incomum de obstrução duodenal, com sintomas inespecíficos, confirmada com exames contrastados, cujo diagnóstico depende do alto índice de suspeição da equipe médica.

The superior mesenteric artery syndrome (SAMS) or Wilkie syndrome is a rare condition characterized by partial or complete obstruction of the third portion of the duodenum by the superior mesenteric artery in the anteror face and by aorta and spine on the posterior face. The present case is grom a patient presenting after a colecistectomy with uncontrollable vomiting after meal, not improved with anti-emetics, being in a guether evaluation diagnosed in SAMS. As the patient did not respond to medical treatment, surgical treatment was chosen. After surgery the patient has be in gollowed for 18 months, completely asymptomatic. The SAMS is an uncommon cause of duodenal obstruction, wit nonspecific c symptoms, confirmed with contrast studies, whose diagnosis depends on a high index of suspicion of the medical team.

Superior mesenteric artery compression syndrome - case report

Superior mesenteric artery syndrome is an entity generally caused by the loss of the intervening mesenteric fat pad, resulting in compression of the third portion of the duodenum by the superior mesenteric artery. This article reports the case of a patient with irremovable metastatic adenocarcinoma in the sigmoid colon, that evolved with intense vomiting. Intestinal transit was carried out, which showed important gastric dilation extended until the third portion of the duodenum, compatible with superior mesenteric artery syndrome. Considering the patient's nutritional condition, the medical team opted for the conservative treatment. Four months after the surgery and conservative measures, the patient did not present vomiting after eating, maintaining previous weight. Superior mesenteric artery syndrome is uncommon and can have unspecific symptoms. Thus, high suspicion is required for the appropriate clinical adjustment. A barium examination is required to make the diagnosis. The treatment can initially require gastric decompression and hydration, besides reversal of weight loss through adequate nutrition. Surgery should be adopted only in case of clinical treatment failure. (AU)

A síndrome da artéria mesentérica superior é uma entidade clínica causada geralmente pela perda do tecido adiposo mesentérico, resultando na compressão da terceira porção do duodeno pela artéria mesentérica superior. Esse artigo relata o caso clínico de uma paciente portadora de adenocarcinoma de cólon sigmoide metastático irressecável, que evoluiu com vômitos incoercíveis. Realizou-se, então, trânsito intestinal que evidenciou dilatação gástrica importante, que se prolongava até a terceira porção duodenal, quadro radiológico compatível com pinçamento da artéria mesentérica superior. Diante da condição nutricional da paciente, foi optado por iniciar medidas conservadoras (porções alimentares pequenas e mais frequentes, além de decúbito lateral esquerdo após as refeições). Quatro meses após a cirurgia e as medidas conservadoras, a paciente não apresentava mais vômitos pós-prandiais, nem emagrecimento. A síndrome da artéria mesentérica inferior é incomum e os sintomas podem ser inespecíficos. Sendo assim, um índice elevado de suspeita é exigido no ajuste clínico apropriado. O diagnóstico é feito, habitualmente, através de exame radiológico contrastado. O tratamento pode, inicialmente, exigir a descompressão gástrica e a reposição volêmica, além da reversão da perda de peso com nutrição adequada. A cirurgia deve ser reservada para os casos de falha do tratamento clínico. (AU)

Acute and chronic mesenteric ischemia: MDCT findings / Isquemia mesentérica aguda e crônica: achados tomográficos

Mesenteric ischemia is caused by a reduction in mesenteric blood flow. It can be divided into acute and chronic, based upon the rapidity and the degree to which the blood flow is compromised. The authors retrospectively reviewed 22 cases of mesenteric ischemia, diagnosed by multidetector computed tomography (MDCT) in our service, and confirmed by surgery or clinical follow-up. The frequency of the diagnostic findings of chronic and acute mesenteric ischemia was evaluated. The improvement of three-dimensional (3D) MDCT allows accurate assessment of mesenteric vessels. Therefore, it demonstrates changes in ischemic bowel segments helpful in determining the primary cause of the disease, and can identify the complications in patients with acute and chronic mesenteric ischemia.

A isquemia mesentérica é causada pela redução do fluxo sanguíneo mesentérico. Essa patologia pode ser dividida em aguda e crônica, baseada na rapidez e no grau em que o fluxo sanguíneo está sendo comprometido. Os autores retrospectivamente revisaram 22 casos de isquemia mesentérica, diagnosticados por tomografia computadorizada com mutidetectores (TCMD) em nosso serviço, e confirmados por cirurgia ou seguimento clínico. Os achados diagnósticos de isquemia aguda e crônica e sua frequência foram avaliados. Os avanços na TCMD 3D (tridimensional) permitiram o acesso detalhado aos vasos mesentéricos. Além disso, é possível demonstrar alterações nos segmentos intestinais, auxiliando na identificação da causa primária da doença e podendo identificar as complicações associadas a isquemia mesentérica e crônica.

Síndrome de Wilkie: presentación de un caso / Superior artery syndrome: Wilkie's Syndrome: case report

El síndrome de Wilkie o síndrome de la arteria mesentérica superior es una rara condición médica originada por la compresión vascular de la tercera porción duodenal entre la arteria mesentérica superior y la aorta abdominal. Los factores predisponentes incluyen desórdenes alimenticios, enfermedades catabúlicas severas, enfermedades de la columna vertebral, trauma severo y estados postoperatorios. El síntoma clinico típico es el dolor epigástrico, intermitente, acompañado de vómitos voluminosos. La duodenografía hipotónica con bario constituye el gold standard para su estudio, pero actualmente la tomografía computada con multidetectores ofrece mayores ventajas diagnósticas. El tratamiento quirúrgico incluye duodenoyeyunostomía, gastroyeryunostomía o lisis del ligamento de Treitz, que pueden realizarse por vía convencional o laparoscópica.

Wilkie's syndrome or superior mesenteric artery syndrome is a rare medical condition caused by vascular compression of the third duodenal portion between the superior mesenteric artery and abdominal aorta. The predisposing factors include eating disorders, severe catabolic diseases, and diseases of the spine, severe trauma and postopertive states. The typical symptom is intermittent epigastric pain, accompanied by vomiting. The hypotonic duodenography with barium is the gold standard for study, but now with the multidetector row CT scan offers greater diagnostic advantages. Surgical treatment includes duodenojejunostomy, gastrojejunostomy and lysis of the ligament of Treitz, which may be performed conventional or laparosocopic.
