RESUMEN Los aneurismas venosos, en especial de la extremidad superior, son malformaciones vasculares de baja frecuencia. Se presentó el manejo de dos pacientes del sexo femenino atendidas en el Servicio de Angiología y Cirugía Vascular del Hospital General Docente "Dr. Agostinho Neto" de la provincia Guantánamo, Cuba, a las que se les diagnosticaron aneurismas en diferentes segmentos del sistema venoso superficial de la extremidad superior, los que se resecaron quirúrgicamente y se les confirmó el diagnóstico mediante biopsia.

ABSTRACT Venous aneurysms, especially the ones located in the upper limbs, are vascular malformations with low incidence in the population. Two cases of venous aneurisms on female patients showed up at the Angiology and Vascular Surgery services at the General Teaching Hospital ¨Dr. Agostinho Neto¨ in Guantanamo, Cuba. Aneurism diagnosis was confirmed through biopsy. They were located in different segments of the superficial venous system of the upper limbs, and were surgically resected.

RESUMO Os aneurismas venosos, principalmente de membro superior, são malformações vasculares de baixa frequência. Foi apresentada a gestão de duas pacientes do sexo feminino atendidas no Serviço de Angiologia e Cirurgia Vascular do Hospital General Docente "Dr. Agostinho Neto" da província de Guantánamo, Cuba, que foram diagnosticados com aneurismas em diferentes segmentos do sistema venoso superficial do membro superior, os quais foram ressecados cirurgicamente e o diagnóstico foi confirmado por biópsia.

Aneurismas de artéria esplênica: história natural e técnicas de tratamento / Splenic aneurysms: natural history and treatment techniques

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.

Aneurisma de arteria testicular: reporte de un caso y revisión de la literatura / Testicular artery aneurysm: case report and review of the literature

Resumen: Introducción: El aneurisma de la arteria testicular es poco frecuente; el término se describe como la dilatación de cualquier vaso sanguíneo en el cuerpo. Caso clínico: Se presenta el caso de un paciente de 15 años con un aneurisma de la arteria testicular izquierda sin ningún antecedente de importancia familiar ni personal, quien se presentó a consulta por aumento de volumen en la región inguinal de larga evolución, acompañado de dolor esporádico y sin más síntomas. Se diagnosticó hernia inguinal y se procedió a cirugía. El diagnóstico se realizó de manera posoperatoria por medio de estudio histopatológico. En este caso, se destaca la presentación de un aneurisma verdadero de la arteria testicular y el resultado después del tratamiento quirúrgico definitivo. Conclusiones: La etiología del aneurisma y del pseudoaneurisma reportada en la literatura se describe posterior a un traumatismo testicular, y en pocos casos de origen congénito. Las manifestaciones clínicas pueden ser dolor y una masa inguinal, y muchas de las veces pueden confundirse con hernias inguinales o ser una patología agregada, por lo que el abordaje de los pacientes con patología inguinal o testicular debe ser protocolizado e incluir el aneurisma dentro de los diagnósticos diferenciales.

Abstract: Background: Aneurysm of the testicular artery is a rare entity; the term is described as the dilation of any blood vessel in the body. Case report: An 18-year-old patient with a left testicular artery aneurysm, with no family or personal history of medical importance, presented for consultation due to a volume increase of long evolution in the inguinal region, accompanied by sporadic pain with no other symptoms. The testicular artery aneurysm was not detectable preoperatively by ultrasound, which only reported data compatible with left inguinal hernia and varicocele. The diagnosis was made postoperatively by a histopathological study. This case highlights the presentation of a true aneurysm of the testicular artery and the result after definitive surgical treatment. Conclusions: The etiology of the aneurysm and pseudoaneurysm reported in the literature is described after a testicular trauma and, a few cases of congenital origin. The clinical manifestations are pain and an inguinal mass, which can be frequently confused with inguinal hernias or an aggregated pathology. Therefore, the approach of patients with inguinal or testicular pathology should be protocolized and include aneurysm within the differential diagnoses.

Aneurisma de la vena de Galeno: diagnóstico prenatal y manejo / Vein of Galen aneurysm: prenatal diagnosis and management

RESUMEN Las malformaciones vasculares cerebrales son infrecuentes, dentro de ellas, el aneurisma de la vena de Galeno (AVG) tiene una incidencia de 1 en 25.000 recién nacidos. El ultrasonido obstétrico de rutina ha permitido el diagnóstico prenatal de dicha alteración, permitiendo establecer el pronóstico del recién nacido. En la exploración mediante ultrasonido del cerebro fetal, la presencia de una imagen quística supratentorial con flujo turbulento al Doppler color permite establecer el diagnóstico. La asociación con signos de insuficiencia cardiaca ha mostrado altas tasas de mortalidad neonatal. Se presenta el caso de un feto al que se realiza el diagnóstico prenatal mediante ultrasonido y su confirmación por neuroimagenes al nacimiento.

ABSTRACT Cerebral vascular abnormalities are rare. The vein of Galen aneurysmal malformation (VGAM) has an incidence of 1 in 25,000 newborns. The routine obstetric ultrasound has allowed the prenatal diagnosis and establish the prognosis of the newborn. In the ultrasound examination of the fetal brain, the presence of a supratentorial cystic image with turbulent flow to the color Doppler makes the diagnosis. The association with signs of heart failure have shown high neonatal mortality. We present a case of a fetus with prenatal diagnosis of VGAM by 2D ultrasound and confirmation by neuroimaging at birth.

Internal carotid artery aneurysm mimicking normal-tension glaucoma / Aneurisma de carótida interna simulando glaucoma de pressão normal

ABSTRACT Differentiating glaucomatous from nonglaucomatous optic disc cupping remains challenging. We present a case of a 48-year-old woman with an internal carotid aneurysm of approximately 3.5 mm × 6.5 mm that mimicked normal-tension glaucoma. The patient had a 2-year history of low vision acuity in her left eye and frontal oppressive headache. Owing to the carotid aneurysm, she developed an asymmetric vertical cup-to-disc ratio above 0.2, and marked inferotemporal neuronal rim loss and pallor of the residual rim were noted in the left disc. She also developed a visual field defect with an arcuate scotoma in the left eye. The patient was referred to a neurosurgeon and underwent endovascular aneurysm occlusion. This case highlights the diagnostic importance of recognizing that many neurological defects remain underdiagnosed.

RESUMO diferenciação de escavações glaucomatosas e não glaucomatosas ainda permanece um desafio ainda nos dias de hoje. Nos descrevemos um caso de aneurisma de carótida interna medindo 3.5mm x 6.5mm que simulava um glaucoma de pressão normal. O caso é sobre uma paciente feminino de 48 anos com história de 2 anos de baixa acuidade visual no olho esquerdo e cefaléia frontal. Devido ao aneurisma de carótida a paciente desenvolveu uma assimetria de escavação vertical maior que 0.2 no olho esquerdo em relação ao direito com defeito localizado da camada de fibras nervosas temporal inferior. Ela também apresentava um defeito arqueado temporal superior a esquerda, cruzando a linha média vertical consistente. Após o diagnostico confirmado pela ressonância magnética funcional, a paciente foi enviada para o neurocirurgião para realização de uma oclusão endovascular do aneurisma. Esse caso nos alerta da importância de se lembrar que não apenas o glaucoma gera escavações suspeitas no disco óptico e que ainda muitos defeitos por causas neurológicas são subdiagnosticados.

Aneurisma cerebral associado a coarctação de aorta em atleta máster de futebol de salão: relato de caso cerebral / Aneurysm associated with coarctation of aorta in federated master soccer: report case

A Coarctação de Aorta (CoA) é uma doença congênita que causa estreitamento do vaso ao longo de seu trajeto. Corresponde aproximadamente 5% das doenças cardíacas congênitas. A CoA frequentemente ocorre no arco distal ou na região descendente. As manifestações clínicas são diversas, sendo a hipertensão arterial um marcador importante de gravidade e lesões em orgãos-alvo. Muitos apresentam cefaleia, tontura, pulsação da cabeça e pescoço, fraqueza, claudicação de membros inferiores. Os aneurismas cerebrais correspondem a 50% nos pacientes com CoA, descritos em 1871 por Eppinger. A fisiopatologia é incerta, contudo é de conhecimento o baixo risco de ruptura e que seu tamanho é menor que os demais aneurismas. Raramente os aneurismas são encontrados em pessoas acima de 50 anos sendo mais comum entre 20-30 anos. Os pacientes que sobrevivem após os dois anos sem intervenção evoluem sem complicações nas maioria dos casos. Relato de Caso: paciente, 46 anos, engenheiro e jogador de futebol de salão master federado desde os 15 anos de idade. Apresentou-se na emergência com quadro de cefaleia de forte intensidade, a pior da vida, com paraparesia de membros inferiores, náuseas e vômitos. Ao exame físico estava em mal estado geral, sopro sistólico contínuo em região interescapular e sopro em diamante em região de precordio, pressão arterial de 180 x100 mmHg, normocardio, força muscular grau 2 em membros inferiores, ausência de pulsos pediosos em membros inferiores e anisocoria. Realizado tomografia de crâneo que evidencia a hemorragia subaracnoidea fisher 2, posteriormente com a angiotomografia cerebral constatou dois aneurismas saculares. Realizado eletrocardiograma, ecocardiograma e fundo de olho sem lesões de órgãos-alvo. Devido à característica do sopro evidenciado no exame e ao Rx de tórax com Sinal de Rosler e 3 invertido solicitou-se uma angiotomografia de aorta que mostrou uma CoA da aorta descendente. Comentários: o caso apresentando apresenta um paciente de 46 anos, jogador de futebol profissional sem sintomas até o presente momento, em tratamento irregular para hipertensão arterial desde os 24 anos de idade. Na grande maioria dos casos de CoA os pacientes adultos jovens e idosos evoluem com lesões de órgãos-alvo e complicações decorrentes da hipertensão de longa data. O presente caso demonstra a necessidade de um exame físico completo, a investigação ativa de hipertensão secundária em pacientes jovens

Coarctation of the Aorta (CoA) is a congenital disease that causes narrowing of the vessel along its way. Measure up 5 % of congenital heart disease. CoA often occurs in the distal arch or descending aorta. Clinical manifestations are diverse, arterial hypertension being an important marker of severity and lesions in organs, many show with headache, dizziness, pulsation of the head and neck, weakness, claudication of the legs. Described in 1871 by Eppinger, Cerebral aneurysms correspond to 50% in patients with CoA. Rarely, aneurysms are found in people over 50 years of age and are more common in the 20-30 year age group. Patients who survive without the necessity of intervention, after two years, have being develop uncomplicated. Case Report: patient, 46 years old, engineer and federated master soccer player since 15 years old. Admited in the emergency department reporting the worst headache of his life, associated, paraparesis of lower limbs, nausea and vomiting. At physical exam: continuous systolic murmur in interscapular region and diamond shaped systolic murmur at precordium. Arterial blood pressure was 180 x100 mmHg, normocardium, muscle strength level 2 in lower limbs , absence of pedis's pulses in lower limbs and anisocoria. Cranial CT scan showed hemorrhage subarachnoid (Fisher 2) and the cerebral angiotomography revealed two saccular aneurysms. Electrocardiogram, echocardiogram and fundus of the eye without lesions. Owing to the characteristic of the murmur evidenced at physical exam and the Rosler's Signal, "3 Sign" seen and at chest X- Ray, an aortic angiotomography was performed which showed a Coa of the descending aorta. Conclusion: the case presents a patient of 46 years, professional soccer player with no symptoms until the present moment, in irregular treatment for hypertension since the 24 years of age. In majority of cases of CoA, young-adult and elderly patients develop with target organ damage and complications resulting from long-standing hypertension. Therefore, a complete physical examination, the active investigation of secondary hypertension in young patients, becomes essential.

Tratamento endovascular de aneurisma de aorta abdominal com erosão de vértebra lombar associada à doença de Behçet: relato de caso / Endovascular repair of abdominal aortic aneurysm with lumbar vertebral erosion in Behçet's disease: case report

A doença de Behçet é uma doença sistêmica, multifatorial e autoimune com diversas manifestações clínicas, entre elas o acometimento vascular. Aneurisma de aorta associado a erosão de vértebra lombar é condição rara na literatura, existindo apenas quatro relatos de caso nas bases de dados da PubMed. O presente artigo relata o caso de paciente do sexo feminino com diagnóstico de Doença de Behçet de longa data e aneurisma sacular de aorta abdominal infrarrenal com erosão de vértebra lombar. O caso foi tratado por meio de técnica endovascular com colocação de endoprótese monoilíaca e enxerto fêmoro-femoral cruzado, devido a limitações anatômicas da bifurcação aórtica. O artigo aborda a raridade desse tipo de apresentação da doença e o desfecho do tratamento e apresenta revisão da literatura sobre esse tema

Behçet's disease is an autoimmune, multifactorial, systemic condition with several clinical manifestations, including vascular disorders. An aortic aneurysm with vertebral erosion is rare in association with this pathology and there are only four case reports listed on the PubMed database. This article reports the case of a female patient with a long-standing diagnosis of Behçet's Disease who developed a saccular infrarenal abdominal aortic aneurysm with lumbar vertebral erosion. Her surgical treatment consisted of endovascular repair with a monoiliac endoprosthesis and a femorofemoral crossover bypass, because of limitations imposed by the anatomy of the aortic bifurcation. This paper discusses the rarity of this presentation of the disease and treatment outcomes and offers a brief review of the relevant literature

Aneurisma verdadeiro pós-traumático de artéria temporal / True posttraumatic aneurysm of the temporal artery

Os aneurismas de artéria temporal pós-traumático são eventos raros. Geralmente, são pseudoaneurismas. Como a causa mais frequente são ferimentos contusos, deve-se investigar todo paciente que possuir nodulação pulsátil na região da artéria temporal. O paciente apresentava protuberância pulsátil em região frontal direita há quatro meses, após queda de objeto pontiagudo, e o eco-Doppler evidenciou dilatação aneurismática. Assim, foi indicada sua excisão, que foi realizada com sucesso. O exame anatomopatológico demonstrou aneurisma verdadeiro traumático de artéria temporal superficial. Ocorrem devido ao fato de a artéria temporal superficial se localizar diretamente sobre o periósteo, o que a torna muito superficializada. Os aneurismas verdadeiros pós-traumáticos de artéria temporal são extremamente raros e podem ser confundidos com diversas outras afecções, como lipomas e cistos sebáceos.

Posttraumatic aneurysms of the temporal artery are rare events and are generally pseudoaneurysms. Since the most frequent cause is blunt injury, all patients with a pulsating nodule in the region of the temporal artery should be investigated. This patient presented with a pulsating protuberance in the right frontal area with onset 4 months previously after being hit by a falling sharp object. Doppler ultrasonography showed evidence of aneurysmal dilatation, which was excised successfully. Pathology results demonstrated a true traumatic aneurysm of the superficial temporal artery. They occur because the superficial temporal artery is located directly over the periosteum, meaning it is very superficial. True posttraumatic aneurysms of the temporal artery are extremely rare and may be confused with many other conditions, such as lipomas and sebaceous cysts.

Tratamento do aneurisma aterosclerótico da artéria temporal superficial: relato de caso / Treatment of an atherosclerotic aneurysm of the superficial temporal artery: case report

Aneurismas da artéria temporal superficial são incomuns segundo a literatura. A grande maioria é secundária a traumatismos ou cirurgia na região temporal, sendo que 95% dos casos evoluem para pseudoaneurismas. Entretanto, os aneurismas verdadeiros ou espontâneos são extremamente raros e representam 8% dos casos de aneurismas da artéria temporal superficial, sendo estes, geralmente, de origem aterosclerótica. Aneurismas temporais espontâneos podem coexistir com outras lesões vasculares, incluindo aneurismas intracranianos. Nosso relato trata de um paciente com aneurisma de artéria temporal superficial esquerda, de origem aterosclerótica, no qual foi realizada a excisão cirúrgica, sob anestesia geral.

According to the literature, aneurysms of the superficial temporal artery are uncommon. The vast majority are secondary to trauma or surgery in the temporal region and 95% of cases progress to pseudoaneurysms. However, true or spontaneous aneurysms are extremely rare, accounting for 8% of cases of superficial temporal artery aneurysms, and are usually caused by atherosclerosis. Spontaneous temporal aneurysms can coexist with other vascular lesions, including intracranial aneurysms. Our report deals with a patient with an aneurysm of the left superficial temporal artery, of atherosclerotic origin, for whom surgical excision was performed under general anesthesia.

Life-threatening Duodenal Ulcer Bleeding from a Ruptured Gastroduodenal Artery Aneurysm in a Patient with Neurofibromatosis Type 1 / 대한소화기학회지

Vasculopathy is rarely reported in neurofibromatosis type 1, but when it occurs it primarily involves the aorta and its main branches. Among vasculopathies, aneurysmal dilatation is the most common form. Although several case reports concerning aneurysms or pseudoaneurysms of visceral arteries in neurofibromatosis type 1 patients have been reported, there are no reports describing gastroduodenal artery aneurysms associated with neurofibromatosis type 1. We experienced a case of life-threatening duodenal ulcer bleeding from a ruptured gastroduodenal artery aneurysm associated with neurofibromatosis type 1. We treated our patient by transarterial embolization after initial endoscopic hemostasis. To our knowledge, this is the first reported case of its type. High levels of suspicion and prompt diagnosis are required to select appropriate treatment options for patients with neurofibromatosis type 1 experiencing upper gastrointestinal bleeding. Embolization of the involved arteries should be considered an essential treatment over endoscopic hemostasis alone to achieve complete hemostasis and to prevent rebleeding.

Fibrosarcoma de arteria pulmonar simulando un síndrome de Hughes Stovin / Pulmonary artery sarcoma mimicking a Hughes Stovin syndrome. Report of one case

Pulmonary artery sarcoma is an uncommon entity with high mortality. Its clinical presentation is usually indistinguishable from pulmonary embolism, which leads to a significant delay in diagnosis. Hughes-Stovin syndrome is characterized by venous thrombosis and aneurysms of the pulmonary or bronchial artery. We report a 59 year-old female with a history of recurrent pulmonary embolism. In the last thromboembolic episode a pulmonary artery aneurysm was found on a CT scan. The patient was operated performing a left inferior lobectomy. The patient died five days after surgery and the pathological examination of the surgical piece revealed a pulmonary artery sarcoma.

Arteria subclavia derecha aberrante en niños examinados en el Instituto Nacional de Cardiología Ignacio Chávez (1992-2012) / Aberrant right subclavian artery in children examined at the National Institute of Cardiology Ignacio Chavez (1992-2012)

Objetivos: Dentro de las malformaciones vasculares de las arterias en el tórax encontramos: 1) doble arco aórtico; 2) arco aórtico derecho y conducto arterioso izquierdo persistente; 3) arteria subclavia derecha aberrante; 4) arteria pulmonar izquierda aberrante, y 5) arteria innominada anómala. Se revisan los pacientes con arteria subclavia derecha aberrante y su manejo. Métodos: Se estudiaron en forma retrospectiva los expedientes de 29 pacientes en edad pediátrica, de enero de 1992 a diciembre 2012, con las siguientes variables: edad de inicio de los síntomas, manifestaciones clínicas, defectos cardiovasculares, método diagnóstico y abordaje quirúrgico. Resultados: El mayor número de pacientes cursó de forma asintomática, únicamente el 31% lo hizo con síntomas durante el primer año de vida, y se llevó a cabo el diagnóstico en un 35% mediante cateterismo. Fue la persistencia del conducto arterioso la cardiopatía más frecuente, con un 13%; el síndrome de Down se encontró en un 21% de los pacientes. El tratamiento más utilizado fue la sección de la arteria subclavia aberrante para la liberación del esófago. Conclusiones: Es importante la sospecha diagnóstica en pacientes con sintomatología durante la alimentación, con trastornos de la deglución con sólidos y, en algunos casos, con disfagia o hasta con dificultad respiratoria. Un número significativo de estos pacientes no son diagnosticados oportunamente, algunos alcanzan la edad adulta sin diagnóstico. El hallazgo de esta malformación ocurre durante los estudios de imagen, cuando se evalúa la aorta o en el estudio del reflujo gastroesofágico, ya que con el trago de bario se aprecia la compresión extrínseca del esófago.

Objectives: Congenital vascular malformations of the major arteries in the chest have been classified into 5 groups: 1) double aortic arch; 2) right aortic arch with left ligament or persistent ductus arteriosus; 3) aberrant subclavian artery; 4) aberrant left pulmonary artery, and 5) anomalous innominate artery. We reviewed the patients with aberrant right subclavian artery and their treatment. Methods: We studied retrospectively the records of 29 patients with aberrant right subclavian artery in childhood, from January 1992 to December 2012, analyzing the following variables: age at onset, clinical manifestations, associated cardiovascular defects, diagnosis and surgical approach method. Results: We found that most patients have an asymptomatic course, only 31% of them course with symptoms during the first year of life, with an incidental diagnosis of 35% during catheterization or other imaging studies. Patent ductus arteriosus was the most frequently associated congenital malformation, with 13%. Down's syndrome was found in 21%. The most common treatment was surgical section of the aberrant subclavian artery to release the esophagus. Conclusions: This vascular abnormality must be suspected in those patients with dysphagia, dyspnea, chest pain during feeding or breathing difficulties. A significant number of patients are not diagnosed in time, some reach adulthood without a diagnosis. This malformation is often found in imaging studies when evaluating the aorta or in a gastroesophageal reflux study, in which the barium bolus reveals the extrinsic compression of the esophagus.

Embolization of splenic artery aneurysm associated with gastrointestinal bleeding: case report / Embolização de aneurisma de artéria esplênica associado à hemorragia digestiva: relato de caso

The splenic artery is the visceral vessel that is most often affected by aneurysmal disease. Occasionally, gastrointestinal bleeding may signify that the aneurysm is in communication with the digestive tract. We report on the case of a 64-year-old multiparous patient with intermittent digestive bleeding caused by a splenic artery aneurysm who was successfully treated with endovascular embolization.

A artéria esplênica é o vaso visceral mais acometido pela doença aneurismática. Ocasionalmente, um sangramento gastrointestinal pode refletir uma comunicação entre o aneurisma de artéria esplênica e o trato digestivo. Relatamos o caso de uma paciente de 64 anos com hemorragia digestiva intermitente devida a aneurisma de artéria esplênica, a qual foi submetida ao tratamento endovascular por embolização com sucesso.

Aneurisma y fístula arterio-venosa renal: manejo quirúrgico laparoscópico asistido por robot / Renal artery aneurysm: robotic resolution

Introduction: Renal artery aneurysm is uncommon conditions, presenting a therapeutic challenge. Aim: To report a case of a complex intrarenal aneurysm associated with a arterio-venous fistula high flow, treated by robotic assistance. Case report: A 51 year-old man, with a long history of hypertension, was diagnosed of a complex intrarenal aneurysm, in routine radiological follow-up. Endovascular treatment was no possible due to an associated high flow arterio-venous, so robotic surgery was performed. The tributary arterial branch was dissected at the renal pedicle, and ligated easily. The radiological follow-up showed a complete resolution and normal renal function. Conclusion: This case, of low frequency, illustrates a successfully manner of resolution of a complex renal vascular pathology...

Introducción: Los aneurismas de la arteria renal constituyen una patología infrecuente, y plantean dificultades en la decisión terapéutica.

Conclusión: Este caso, de baja frecuencia, ilustra una forma de resolución de una patología vascular renal, con éxito...

Subclavian and axillary arterial aneurysms: two case reports / Aneurismas do segmento subclavio-axilar: relato de dois casos

Aneurysms of the subclavian-axillary segment are rare, but when diagnosed they must be treated. This article describes two cases of aneurysms of the upper extremities, one in a subclavian artery and the other in an axillary artery. The first case was a 71-year-old male with a pulsating supraclavicular bulge on the right and muscle weakness in the ipsilateral extremity. Duplex scanning and arteriography confirmed the diagnosis of aneurysm of the right subclavian artery and the patient underwent aneurysmectomy and end-to-end anastomosis. The second case was a 24-year-old female patient, with no history of comorbidities, who presented with a pulsating mass in the right axillary region and paresthesia of the ipsilateral extremity. Duplex scanning and arteriography confirmed an aneurysm in the right axillary artery, which was successfully treated with aneurysmectomy and end-to-end anastomosis. Pathology findings showed that the first case was an atherosclerotic aneurysm and the second was a congenital aneurysm.

Os aneurismas do segmento subclávio-axilar são de ocorrência rara e, uma vez diagnosticados, devem ser tratados. Neste trabalho, relatamos dois casos de aneurismas de membros superiores, sendo um da artéria subclávia e outro da artéria axilar. No primeiro caso, o paciente de 71 anos, sexo masculino, apresentava abaulamento pulsátil supraclavicular direito associado à fraqueza muscular no membro ipsilateral. Foram realizados duplex scan e arteriografia, que confirmaram o diagnóstico de aneurisma da artéria subclávia direita, sendo o paciente submetido à aneurismectomia com anastomose término-terminal. No segundo caso, uma paciente de 24 anos, do sexo feminino, sem antecedentes mórbidos ou comorbidades, apresentava queixa de massa pulsátil na região axilar direita associada à parestesia no membro ipsilateral. O duplex scan e a arteriografia confirmaram o aneurisma da artéria axilar direita, que foi tratado com aneurismectomia e anastomose término-terminal com sucesso. O diagnóstico anátomo-clínico foi de aneurisma aterosclerótico no primeiro caso e, no segundo caso, de aneurisma congênito.

Síndrome Hughes-Stovin: Caso clínico / Hughes-Stovin syndrome: Report of one case

We report a 25yearold mole admitted to a critical care unit for fever, lung opacities and acute respiratory failure. A chest angio-CAT sean showed multiple pulmonary artery aneurysms. A deep venous thrombosis of both lower limbs was also documented. A Hughes-Stovin syndrome was postulated. An inferior vena cava filter was placed. The patient received antimicrobial therapy subsiding fever and respiratory failure. Subsequently, he was treated with intravenous and oral steroids and one dose of cyclophosphamide. The patient was discharged in good conditions fifteen days after admission.

Marfan's syndrome: pre-pubertal aortic rupture with left coronary artery aneurysms and fistulas / Síndrome de Marfan: ruptura aórtica prepubertal con fístulas y aneurismas de la arteria coronaria izquierda

Aortic dissection and rupture occur in 20-40% of patients with Marfan's syndrome. This occurs predominantly in the third and fourth decade of life, contributing to the increased morbidity and mortality of this specific group of patients. This is the first known documented case report of pre-pubertal left coronary sinus rupture with left coronary artery aneurysms with fistulous communication to both the superior vena cava and right superior pulmonary vein, presenting with a continuous murmur.

La disección y ruptura aórticas ocurren en 20-40% de los pacientes con el síndrome de Marfan. Esto ocurre predominantemente en la tercera y cuarta décadas de la vida, contribuyendo al aumento de la morbilidad y la mortalidad de este grupo específico de pacientes. Éste es el primer reporte de un caso documentado conocido de ruptura prepubertal del seno coronario izquierdo con aneurisma de la arteria coronaria izquierda, y comunicación fistulosa tanto con la vena cava superior como con la vena pulmonar superior derecha, acompañada de un soplo continuo.
