ABSTRACT

RESUMEN Fundamento: los aneurismas de la vena porta son entidades poco frecuentes, representan aproximadamente el 3% de los aneurismas del sistema venoso. La mayoría de los aneurismas de la vena porta se detectan en pacientes con hígado sano, aunque en algunas ocasiones la hipertensión portal podría favorecer el desarrollo de la patología. Los lugares más comunes son la confluencia venosa esplenomesentérica, la vena porta principal y las ramas de la vena porta intrahepática en los sitios de bifurcación. Objetivo: presentar el caso de un paciente portador de una aneurisma de la vena porta. Presentación del Caso: Paciente femenina, blanca de 49 años de edad con antecedentes de trastornos dispépticos, y en ocasiones, dolor a nivel del hipocondrio derecho. Su examen físico era negativo y la impresión diagnóstica de su médico de asistencia era litiasis vesicular. Durante la realización del examen ultrasonográfico se encuentra como dato positivo una dilatación de tipo aneurismático de la vena porta en el inicio de su trayecto intrahepático de 18 mm de diámetro, y el resto del examen resultó negativo. Conclusiones: Por lo inusual de este caso se decide hacer su presentación.


ABSTRACT: portal vein aneurysms are uncommon, representing approximately the 3% of venous system aneurysms. Most portal vein aneurysms are detected in patients with healthy liver, although on some occasions portal hypertension could favor their development. The most common sites are the splenomesenteric venous confluence, the main portal vein and the branches of the intrahepatic portal vein at bifurcation sites. Objective: to present the case of a patient with a portal vein aneurysm. Case Presentation: A 49-years-old white female patient with a history of dyspeptic disorders, and sometimes pain in the right upper quadrant. Her physical examination was negative and the diagnostic impression from her attending physician was gallstones. During the ultrasound examination, an aneurysmal dilatation of the portal vein at the beginning of its intrahepatic path of 18 mm in diameter was found as a positive finding, being the rest of the examination negative Conclusions: Due to the unusual nature of this case, it was decided to present it.

ABSTRACT

Resumen La anomalía de Ebstein es una cardiopatía congénita poco común que se asocia a la presencia de vías de conducción anómalas y episodios de taquicardia supraventricular frecuentes, algunos inestables. La asociación con alteraciones anatómicas del seno coronario es rara y no ha sido reportada. Se presenta el caso de una paciente de 58 años con enfermedad coronaria, anomalía de Ebstein, episodios de taquicardia ortodrómica y aneurisma del seno coronario, a quien se realizó ablación.


Abstract Ebstein’s disease is a congenital cardiomyopathy, with a low prevalence in the general population. This abnormality has been associated with abnormal cardiac conduction problems, one of the most important being the accessory pathways. In the presence of an accessory pathway, frequent supraventricular tachycardias may occur, some of which are poorly tolerated. The association with the anomalies of the coronary sinus is not currently reported. The case of a 58-year-old woman with Ebstein’s disease, episodes of supraventricular tachycardia, and coronary sinus aneurysm undergoing ablation therapy is presented.

ABSTRACT

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.

ABSTRACT

Venous aneurysm of the head and neck is a rare clinical entity due to its asymptomatic nature and tendency of clinicians to report only surgical results. Whereas the primary aneurysm of internal jugular vein (IJV) in children is being increasingly recognized, secondary aneurysms of veins of the head and neck in adults, notably the external jugular vein (EJV) aneurysm remains only in anecdotal case reports. We present the case of a 63-year-old previously healthy woman who presented with a gradually progressive right lateral neck swelling over the last 18 months. Following the evaluation, she was diagnosed as a case of isolated spontaneous right-sided EJV aneurysm and was managed by surgical excision of the aneurysm.

ABSTRACT

La dilatación idiopática de la aurícula derecha es una entidad poco frecuente. Estimar la verdadera incidencia es dificultoso dado que muchos pacientes son asintomáticos y los síntomas reportados, tanto en niños como en adultos, presentan un amplio espectro de manifestaciones clínicas. Pocos pacientes con diagnóstico prenatal fueron publicados.Se presenta un caso de diagnóstico prenatal de dilatación auricular derecha con un seguimiento de 3 años y 8 meses. El paciente se encuentra asintomático, sin evidencia de trombosis auricular, medicado con ácido acetilsalicílico desde su nacimiento. El seguimiento se realizó con ecocardiogramas regulares; sin embargo, la confirmación diagnóstica fue a través de la resonancia magnética nuclear cardíaca.La importancia del reporte radica en describir una enfermedad rara, potencialmente grave, y cómo el diagnóstico prenatal permite tomar conductas anticipadas, como el monitoreo cardíaco, para la detección de arritmias y el inicio temprano de profilaxis primaria antitrombótic


Idiopathic dilatation of the right atrium is a rare condition. The real incidence of the disease is difficult to estimate since most patients are asymptomatic, although a wide spectrum of symptoms have been reported in children and adults. In the literature, prenatal diagnosis has been reported in few cases.We report a case of prenatally diagnosed right atrial dilation with a 3 years and 8 months follow up. The patient is on acetylsalicylic acid since birth and remained asymptomatic without any atrial thrombosis. We performed regular transthoracic echocardiograms during follow up, however was a cardiac magnetic resonance imaging the method for achieving diagnostic confirmation.The aim of this case report is to describe a rare, potentially serious disease and how prenatal diagnosis allows anticipated actions such as monitoring for cardiac arrhythmia detection and early starting of primary thrombosis prophylaxis.

ABSTRACT

Objetivo: Describir la anatomía quirúrgica de la fisura silviana (FS) a través de disecciones cadavéricas y neuroimágenes; desarrollar su aplicación microquirúrgica. Materiales y métodos: Se estudiaron 10 hemisferios cadavéricos humanos fijados y un cráneo humano en seco, a través de la disección de fibras blancas y de la anatomía arterial y neural, utilizando un microscopio quirúrgico. Las arterias cerebrales fueron inyectadas con silicona coloreada. La anatomía quirúrgica fue correlacionada con la anatomía neuroimagenológica. Finalmente, se recolectó la experiencia microquirúrgica adquirida y, a su vez, la anatomía del Complejo Silviano, fue revisada. Resultados: La FS se extiende desde la cara basal a la lateral del cerebro. Cada superficie tiene una parte superficial (tronco silviano y sus ramos), intermedia (compartimientos anterior y opercular lateral) y profunda (compartimiento esfenoidal, hendidura insular anterior y lateral y la región retroinsular). En 7 de los 10 hemisferios, el surco central no se intersectó con la FS en la superficie lateral del cerebro. En el 80% de los hemisferios, la principal bifurcación de la arteria cerebral media se localizó en o proximal al limen insular. Debajo de la pars triangularis se localiza el punto más ancho de la superficie lateral de la FS. Los autores comienzan la disección de la misma en o proximalmente a este punto. Conclusiones: El conocimiento anatómico profundo y su aplicación a las neuroimágenes, son herramientas esenciales para el planeamiento prequirúrgico y son requisitos mandatorios para operar con seguridad a través y alrededor de la FS


Objective: The aim of this study is to describe the microsurgical anatomy of the sylvian fissure, through cadaveric dissections and neuroimaging and to elucidate its clinical application for microsurgery. Methods: One human skull and ten cadaveric human hemispheres were studied through white matter fiber dissections and arterial and neural anatomy of the sylvian fissure and insular dissections under the microscope. The cerebral arteries were perfused with colored latex. The surgical anatomy was correlated with neuroimaging anatomy. Finally, the microsurgical experienced gained applying this anatomical knowledge was gathered, and the literature about the anatomy of the sylvian complex was revised, as well. Results: The Sylvian fissure extends from the basal to the lateral surface of the brain. Each surface has a superficial (sylvian stem and its rami), intermediate (anterior and lateral opercular compartments) and deep parts (sphenoidal compartment, anterior and lateral insular clefts and retroinsular region). In 7 out of 10 hemispheres, the central sulcus did not intersect with the sylvian fissure on the lateral surface of the brain. In 80% of the hemispheres, the middle cerebral artery main bifurcation was localized at or proximal to the limen insulae. Beneath the pars triangularis, the widest point of the lateral surface of the sylvian fissure is located. The authors start dissecting the sylvian fissure at this point. Conclusion: The thorough anatomical knowledge with its clinical application in modern neuroimaging are essential tools for preoperative planning and are mandatory requisites to safely operate through and around the sylvian fissure anatomical complex.

ABSTRACT

Popliteal artery aneurysms is the most frequent peripheral aneurysm, predominantly affects men over 60 years of age and has a high morbidity associated to his complications, among which are ischemic complication, which can often end in amputation of the limb. Less frequent complications such as neuropathic and venous complications, particularly deep vein thrombosis, are equally relevant. Case presentation: Patient with an aneurysm of the popliteal artery complicated by thrombosis of the adjacent popliteal vein. Color Doppler ultrasound plays a fundamental role in the diagnosis.

ABSTRACT

INTRODUÇÃO: O aneurisma de VE (ANEUVE) é uma complicação pós IAM e da doença de Chagas. É causa de arritmias, ICC e tromboembolismo. O CDI está indicado para prevenção da morte súbita arrítmica na ausência de causas removíveis. O ANEUVE pode ser ressecado cirurgicamente e, quando, aplica-se outras abordagens (endoaneurismorrafia, reconstrução do VE, revascularização miocárdica e ablação do foco arritmogênico) pode abolir o circuito da arritmia, melhorar a função ventricular e com isso o prognóstico dos pacientes (P). Objetivo: Apresentar a experiência da fase hospitalar da aneurismectomia de VE com TV instável. Métodos: Revisaram-se os prontuários de 14 P com ANEUVE e TVS hemodinamicamente instável (10P com ICo, 4P DCh; média de idade 60±5,6a, variando entre 52 e 70 a; média da FEVE 35±10%). Após a aneurismotomia, procedeu-se a indução da TV com estimulação ventricular programada (EVP) seguida de mapeamento endocárdico. Após a localização da área alvo realizou-se a ablação com cateter com RF (Cardioablate®). Nova EVP era realizada e, em caso de não indução da TV a cirurgia era complementada com a endoaneurismorrafia e reconstrução do VE com retalho de pericárdio. A revascularização miocárdica era a etapa final caso indicada. Antes da alta hospitalar, os P eram submetidos à EVP. Sendo negativa recebiam alta, em tratamento clínico, em caso positivo submetiam-se ao implante do CDI. Resultados: O ANEUVE localizou-se predominantemente na região anterior. A trombose ventricular foi observada em 3/14P (21%). A TV foi induzida e ablacionada com RF em 14/14 casos (100%). Em apenas 1P (7%) a TV foi reinduzida após a aneurismectomia. Houve tendência de melhora da FE no PO em 12/14P (35±9,8 vs. 39±7,7%; p=0,156). Em 13/14P (93%) a TV não mais foi induzida. Um P (7%) morreu por choque séptico, ainda internado. Um P implantou CDI devido a reindução de TV. Os outros P receberam alta estáveis. Conclusões: a) a aneurismectomia com abordagens para TVS é conduta eficaz em P com risco de MS; b) a comprovação do sucesso terapêutico pode ser demonstrada ainda na cirurgia e confirmada antes da alta com a EVP; c) a conduta utilizada evitou o implante de CDI na maioria dos casos.

ABSTRACT

Aneurisma cerebral (AC) é a dilatação anormal de uma artéria que irriga o cérebro. Cerca de 3,2% da população mundial apresenta algum AC com potencial risco de evoluir para hemorragia subaracnóidea (HSA). OBJETIVO: Descrever o perfil clínico, sociodemográfico e funcional de indivíduos com diagnóstico clínico de AC atendidos em Salvador/BA. MÉTODO: Estudo observacional e transversal, realizado em um hospital de referência em Salvador/BA. Indivíduos maiores de 18 anos com diagnóstico de AC (N=25) roto ou não roto, foram avaliados o perfil sociodemográfico (idade, sexo, escolaridade e ocupação), clinico (comorbidades, hábitos de vida e nível de consciência através da ECG, Escala de Coma de Glasgow) e funcional (MRC, Medical Research Council; ECT, Escala de Comprometimento de Tronco e Rankin Modificada). Variáveis qualitativas foram apresentadas por frequências relativas e as variáveis quantitativas por meio de médias, desvio-padrão ou medianas e intervalo mínimo e máximo. RESULTADOS: Foram incluídos 13 indivíduos diagnosticados com AC, idade mediana de 51, sendo 84,6% do sexo feminino, 30,8% ativos no mercado de trabalho. 61,5% da população apresentou AC não roto e ECG 15. Observamos HAS em 53,8% e obesidade em 7,7%. Cerca de 61,5% eram sedentários, 15,4% etilistas e 30,8% tabagistas. Na avaliação da funcionalidade, o escore MRC mediano foi de 54, Rankin a mediana foi 4 e na ECT de 19,5. CONCLUSÃO: Os achados demonstram uma predominância dos AC em mulheres e declínio funcional dos indivíduos durante o internamento, tornando-se necessário intervenções que visem minimizar possíveis perdas funcionais nesta população.


Cerebral aneurysm (AC) is the abnormal dilation of an artery that irrigates the brain. About 3.2% of the world population has some CA with a potential risk of developing subarachnoid hemorrhage (SAH). OBJECTIVE: To describe the clinical, sociodemographic and functional profile of individuals with a clinical diagnosis of CA treated in Salvador / BA. METHODS: Observational and cross-sectional study, carried out in a reference hospital in Salvador / BA. Individuals over 18 years of age diagnosed with CA (N = 25) ruptured or not, the sociodemographic profile (age, sex, education and occupation), clinical (comorbidities, lifestyle and level of consciousness through ECG, Scale Glasgow Coma) and functional (MRC, Medical Research Council; ECT, Trunk Compromise Scale and Modified Rankin). Qualitative variables were presented by relative frequencies and quantitative variables by means of means, standard deviation or medians and minimum and maximum intervals. RESULTS: 13 individuals diagnosed with CA were included, with a median age of 51, 84.6% of whom were female, 30.8% were active in the labor market. 61.5% of the population had a diagnosis of non-ruptured AC and ECG 15. We observed SAH in 53.8% and obesity in 7.7%. About 61.5% were sedentary, 15.4% drinkers and 30.8% smokers. In the evaluation of functionality, the median MRC score was 54, Rankin the median was 4 and in ECT it was 19.5. CONCLUSION: The findings demonstrate a predominance of CA in women and functional decline of individuals during hospitalization, making interventions necessary to minimize possible functional losses in this population.

ABSTRACT

Abstract Mitral valve aneurysm is a rare and uncommon complication of infective endocarditis leading to a weakened mitral tissue. The most feared mitral valve aneurysm's complications are: perforation and severe mitral regurgitation. Multiple mechanisms have been suggested to explain the development of mitral valve aneurysm in aortic infective endocarditis including: local extension of the infection, the mitral kissing vegetation and aortic regurgitation. We report the case of a 29-year-old man who had infective endocarditis of a native aortic valve and the sub-aortic diaphragm complicated by a perforated mitral valve aneurysm diagnosed only by transesophageal echocardiogram. The patient had no sign of heart failure. We hypothesized that all those mechanisms lead to the developing of the mitral valve aneurysm in this case, but also the presence of the diaphragm favored the spread of the infection.


Resumen Una de las complicaciones poco comunes e inusuales de la endocarditis infecciosa son los aneurismas de la válvula mitral. Las complicaciones más temidas de estos últimos son la perforación y la insuficiencia mitral severa. Diferentes mecanismos pueden explicar el desarrollo de dicha insuficiencia en el contexto de una endocarditis infecciosa, incluyendo una extensión local, una vegetación sobre la válvula mitral y una insuficiencia aórtica. Nuestro caso clínico es el de un joven de 29 años diagnosticado de endocarditis infecciosa sobre su válvula aortica nativa con un diafragma subaortico complicado con un aneurisma de la válvula mitral perforado. El paciente no presentaba signos de insuficiencia cardíaca. Hemos supuesto que todos los mecanismos que hemos evocado anteriormente han llevado al desarrollo de dicho aneurisma, junto con la presencia del diafragma, elemento en favor de la diseminación de la infección.

ABSTRACT

Introducción: Los aneurismas cerebrales de la circulación posterior, representan solo del 8 al 10 % del total de los aneurismas cerebrales, y de estos los de la arteria cerebelosa anteroinferior (AICA) son muy poco frecuentes, por lo que no hay algoritmo de manejo para estas lesiones, se requieren conocimientos anatómicos de vascular y de base de cráneo para el tratamiento de estos, hablando del abordaje quirúrgico, podemos mencionar, el extremo lateral, retrosigmoideo, orbitozigomatico y presigmoideo, que depende del tamaño y localización del aneurisma, ya sea distal o proximal. Presentamos este caso, que tratamos mediante un abordaje retrosigmoideo convencional, el cual nos ofreció un corredor quirúrgico suficiente, sin necesidad de un abordaje mas amplio, en este caso fue un aneurisma distal de la AICA, localizado en el segmento meatal, que se encontró en el complejo neurovascular medio del ángulo pontocerebeloso, muy próximo a los nervios craneales V, VII y VIII. Objetivos: Demostrar que los aneurismas distales de la AICA se pueden manejar mediante un abordaje retrosigmodeo convencional con éxito. Materiales y métodos: El paciente se colocó en posición park bench, bajo fijación esquelética de 3 puntos, con el asterion como punto mas elevado. Se realizo una incisión en forma de C en la mastoides y se realizo un abordaje dirigido hacia el ángulo pontocerebeloso. Resultados: Se logró realizar el clipaje del aneurisma de forma satisfactoria, con un buen resultado clínico del paciente, quien fue egresada a los 4 días sin déficit neurológico. Conclusión: El abordaje retrosigmoideo es una opción terapéutica para el manejo de los aneurismas ubicados en el ángulo pontocerebeloso, específicamente del AICA distal y también se puede usar incluso para los aneurismas distales del PICA.


Background: Cerebral aneurysms of the posterior circulation, representing only 8 to 10% of the total cerebral aneurysms, but the aneurysms of the anteroinferior cerebellar artery (AICA) are very rare, so there is no management algorithm for these lesions, anatomical knowledge of vascular and skull base are known for the treatment of these lesions, in relation of the surgical approach, we can identify, the far lateral, retrosigmoid, orbitozigmatic or presigmoid approaches, which depends on the size and location of aneurysm, either distal or proximal. We present this case, which we treated through a conventional retrosigmoid approach, which offers us a sufficient surgical corridor, without the need for a broader approach, in this case it was a distal AICA aneurysm, located in the meatal segment, which was found in the middle neurovascular complex of the pontocerebellar angle, very close to the cranial nerves V, VII and VIII. Objective: Demonstrate that distal aneurysms of AICA can be managed using a successful conventional retrosigmoid approach. Results: The clipping of the aneurysm was achieved satisfactorily, with a good clinical result of the patient, who was discharged at 4 days without neurological deficit. Conclusion: The retrosigmoid approach is a therapeutic option for the management of aneurysms located in the pontocerebellar angle, specifically of the distal AICA and can also be used even for distal aneurysms of the PICA.

ABSTRACT

Compressive syndromes of peripheral nerves both in the upper and lower limbs are part of daily clinical practice; however, the etiological diagnosis can be challenging and impact on the outcome of the patient. We report five cases with rare etiologies of nerve entrapments: one in the lower limb and four in the upper limbs with the final diagnosis made only during the operation. The patients evolved without post-operative complications and had good outcomes. This series includes the first report of sciatic compression by a lipoma in the popliteal fossa, two lipomas one with compression of infraclavicular brachial plexus and another with compressing the posterior interosseous nerve, and two reports of vascular lesions due to blunt traumas, which are also uncommon. This series adds to the literature more hypotheses of differential diagnoses in nerve entrapments, which is fundamental to surgical decisions and pre-operative planning—and perhaps most importantly prevents wrong diagnosis of idiopathic compressions, which would lead to a completely wrong approach and unfavorable outcomes.

ABSTRACT

Resumen La hemorragia digestiva alta se define como el sangrado originado en el tracto digestivo superior, proximalmente al ángulo de Treitz, y constituye la urgencia gastroenterológica más importante. Tiene una incidencia que varía, según el área estudiada, entre 48 y 160 casos por 100 000 habitantes y año. Aunque puede ser causada por numerosas etiologías, no debemos olvidar aquellas menos comunes, ya que pueden condicionar una alta mortalidad, como es el caso de la rotura de un aneurisma de la arteria hepática. A continuación, mostramos un caso representativo.


Abstract Upper gastrointestinal bleeding is defined as bleeding originating in the upper digestive tract proximal to the Treitz angle and is the most important gastroenterological emergency. Its incidence varies, depending on the area studied, between 48 and 160 cases per 100,000 inhabitants per year. Although it can be caused by numerous etiologies, we must not forget the less common ones such as a ruptured hepatic artery aneurysm since they can condition high mortality. We present a representative case.

Introduction: The aneurysm of the right internal carotid artery is a very rare disease. Its complications are very serious if we take into account the area that irrigates these arteries. The incidence of this disease is low. Objective: To present the clinical manifestations of this disease and the surgical treatment used in this patient. Presentation of the case: Male patient, 58 years old, with a history of arterial hypertension and presenting an aneurysm of the right internal carotid artery with five years of evolution. Such lump increased its size in the last six months; this was confirmed by ecodoppler and angiotomography, so he came to the consultation. The conventional surgical treatment was used: aneurysmectomy and grafting by substitution with polytetrafluroethylene prosthesis without complications. Conclusions: The patient developed successfully after surgery; he is currently evolving after three months of being operated on without complications and he keeps the treatment with antiplatelet agents(AU)

ABSTRACT

Introducción: Los aneurismas del segmento comunicante posterior representan aproximadamente 25% de todos los aneurismas intracraneales, y el 50% de los aneurismas de la arteria carótida interna. El objetivo fue evaluar la eficacia del tratamiento quirúrgico y endovascular en el manejo de aneurismas de esta localización. Material y Métodos: Estudio comparativo retrospectivo. Se revisó las historias clínicas de pacientes con aneurisma del segmento comunicante posterior que ingresaron al departamento de Neurocirugía del Hospital Nacional Guillermo Almenara durante el periodo 2010-2017. Se comparó estancia hospitalaria, complicaciones, mortalidad y estado funcional a los 12 meses, en relación al tratamiento recibido, microquirúrgico o endovascular. Resultados: Se evaluaron 256 pacientes, 111 (43,36%) recibieron tratamiento quirúrgico, y 145 (56,64%) endovascular. En el caso de aneurismas rotos, el estado de independencia funcional fue alcanzado por 68 (66,7%) y 69 (70,4%) pacientes que recibieron tratamiento quirúrgico y endovascular, respectivamente (OR:0.84, IC 95%: 0.46­1.53; p=0.505). Se presentaron complicaciones neurológicas en 37 (36,3%) y 34 (34.7%) pacientes sometidos a tratamiento microquirúrgico y endovascular, respectivamente (OR: 1.07, IC 95%: 0.60­1.91; p=0.912). La estancia hospitalaria promedio fue 19,55±13.85 y 14.06±14.97 días, para pacientes con tratamiento quirúrgico y endovascular, respectivamente (p<0.008). La mortalidad fue 11,8% y 11,2%, con ligera predominancia en el grupo tratado quirúrgicamente (OR: 1.05, IC 95%: 0.44­2.52; p=0.904). Conclusiones: No existe diferencia significativa respecto al resultado funcional a los 12 meses, complicaciones y mortalidad entre ambos tipos de tratamiento en el caso de aneurismas rotos. Los pacientes sometidos a terapia endovascular tuvieron de forma significativa menor estancia hospitalaria


Background: Posterior communicating segment aneurysms represent about the 25% of all intracranial aneurysms and the 50% of the internal carotid artery aneurysms. The objective of the study was to evaluate the efficacy of the surgical and endovascular treatments in the management of the aneurysms of this localization. Methods: Comparative and retrospective study. Clinical charts of patients with aneurysms of the posterior communicating segment were reviewed during the period from 2010 to 2017 in the Guillermo Almenara Hospital. Hospital stay, complications, mortality and functional status at 12 months were compared among endovascular and surgical treatment. Results: Two hundred and fifty-six patients were evaluated, 111 (43,36%) were treated with surgery and 145 (54,64%) with endovascular therapy. Among ruptured aneurysms, functional independence status was reached in 68 (66,7%) and 69 (70,4%) of the patients who were treated with surgery and embolization respectively (OR:0.84, IC 95%: 0.46­1.53; p=0.505). Neurological complications were found in 37 (36,3%) and 34 (34,7%) patients treated with surgery and embolization respectively (OR: 1.07, IC 95%: 0.60­1.91; p=0.912). The mean hospital stay was 19,55±13.85 and 14.06±14.97 days of the patients treated with surgery and embolization respectively. Mortality was 11,8% and 11,2%, with a slight predominance in the surgically treated group (OR: 1.05, IC 95%: 0.44­2.52; p=0.904). Conclusions: There is no significant difference according to functional status at 12 months, complications and mortality among both type of treatments in the group of ruptured aneurysms. Patients treated with endovascular therapy had lower hospital stay with statistical difference

ABSTRACT

Objetivo: Presentar la resolución quirúrgica de un aneurisma gigante de arteria cerebral media mediante técnica de Trapping y By-Pass. Introducción: La tasa de mortalidad a 5 años de pacientes con aneurismas gigantes es del 80%. Debido a su cuello ancho en ocasiones el clipado directo no es posible, requiriendo realizar Trapping del aneurisma seguido de revascularización mediante By-Pass. Material y Método: Se analizaron datos de historia clínica, imágenes complementarias pre y postquirúrgicas, así como imágenes de video intraoperatorias de un paciente portador de aneurisma gigante de arteria cerebral media intervenido en nuestro centro. Resultados: Mediante abordaje Pterional se localizó arteria temporal superficial y sus ramos. Luego de una cuidadosa disección del saco aneurismático se intentó el clipado primario, debido a su cuello ancho, aterosclerosis asociada y trombo intrasacular, el flujo en la rama temporal de arteria cerebral media era comprometido por el clip. Se decidió la oclusión del aneurisma mediante técnica de trapping y, en mismo tiempo quirúrgico, realización de By Pass extra-intracraneano de arteria temporal superficial a rama temporal de arteria cerebral media. A su vez se secciono el aneurisma y se removió el trombo contenido en su interior, logrando disminuir el efecto de masa ejercido por el mismo. Se corroboro permeabilidad intraquirurgica mediante Doppler y en el postoperatorio alejado mediante angiotomografía con reconstrucción 3D. El paciente evoluciono sin complicaciones asociadas con un Rankin modificado de 1. Conclusión: Se presentó resolución quirúrgica de aneurisma gigante de arteria cerebral media mediante técnica de Trapping seguida de By-Pass extra-intra craneano temporo-silviano


Objective: To present the surgical resolution of a giant aneurysm of the middle cerebral artery using Trapping and By-Pass technique. Introduction: The 5-year mortality rate of patients with giant aneurysms is 80%. Due to its wide neck, sometimes-direct clipping is not possible, requiring trapping of the aneu-rysm followed by bypass revascularization. Material and Method: Clinical history data and intraoperative video images of a pa-tient with a giant aneurysm of the middle cerebral artery were analyzed. Results: The superficial temporal artery and its branches were identified through a Pterional approach. After careful aneurysm dissection, primary clipping was attempted, but the flow in the temporal branch of the middle cerebral artery was compromised. Due to its wide neck, associated atherosclerosis and intrasaccular thrombus, an Extra-intracranial bypass was performed from superficial temporal artery to temporal branch of middle cerebral artery, followed by trapping technique of the aneurysm. Then the aneu-rysm was sectioned and the thrombus contained inside was removed, decreasing the mass effect exerted by it. A Doppler probe was used to corroborate bypass permeability, as well as 3D reconstruction angiotomography during the postoperative period. The pa-tient was discharged without associated complications and a modified Rankin scale of 1. Conclusion: Surgical resolution of a giant middle cerebral artery aneurysm was present-ed by Trapping technique followed by extra-intra-cranial temporo-Silvian bypass

ABSTRACT

Resumen Objetivo: Correlacionar las generalidades de la etiología, patogenia, presentación clínica y métodos diagnósticos actuales disponibles para el aneurisma de arteria pulmonar con la muerte súbita o repentina de estos pacientes. Materiales y métodos: Se realizaron revisión del expediente clínico, análisis de la autopsia y revisión bibliográfica. Presentación de caso: Se presenta el caso de un masculino de 39 años con antecedente de hipertensión pulmonar que consultó por disnea súbita. Se abordó el caso como un tromboembolismo pulmonar. El paciente presentó una evolución clínica tórpida y falleció. La autopsia reveló un aneurisma de la arteria pulmonar. Conclusión: Los aneurismas de la arteria pulmonar son poco frecuentes. La presentación clínica es inespecífica. Los métodos diagnósticos más fiables son la sospecha clínica y los métodos de imagen, sin embargo siguen siendo motivo de muerte súbita y repentina; cuyo hallazgo es postmorten.


Abstract Objective: Correlate the generalities of etiology, pathogenesis, clinical presentation and current diagnostic methods available for pulmonary artery aneurysm with sudden death of these patients. Materials and methods: Review of medical record, autopsy analysis and scientific literature. Case presentation: A 39-year-old male with a history of pulmonary hypertension, who consulted for sudden dyspnea. The case was approached as a pulmonary thromboembolism. The patient presented bad clinical evolution and died. Autopsy revealed an aneurysm of the pulmonary artery. Conclusion: Aneurysms of the pulmonary artery are rare. The clinical presentation is nonspecific. The most reliable diagnostic methods are clinical suspicion and imaging methods, however they remain a cause of sudden death; whose finding is postmortem.
