ABSTRACT

El diagnóstico temprano de las lesiones compresivas del nervio óptico adquiere cada vez mayor importancia. La descompresión precoz de este o del quiasma puede resultar una mejora significativa de la función visual, mientras que el diagnóstico erróneo puede ocasionar pérdida visual irreversible, disfunción neurológica o la muerte. Las causas de la compresión de la vía visual anterior son increíblemente variadas. Los meningiomas, los tumores hipofisarios y los aneurismas son las lesiones comúnmente más identificadas como causa de neuropatía óptica compresiva sin edema del disco. Presentamos una paciente femenina de 50 años de edad, quien se sometió a la cirugía de catarata congénita del ojo izquierdo, sin mejoría de la función visual, a lo que se sumó el empeoramiento inespecífico de la calidad visual. La psicofísica visual, la campimetría automatizada y la tomografía de coherencia óptica aportaron hallazgos sugestivos de compresión de la vía visual intracraneal. Se indicó imagen por resonancia magnética de cráneo y órbitas para confirmar la sospecha diagnóstica. La angiografía cerebral demostró la presencia de un aneurisma de la arteria carótida interna, que se trató por vía endovascular con resultados satisfactorios(AU)


The importance of early diagnosis of compressive lesions of the optic nerve is on the increase. Timely decompression of the optic nerve or the optic chiasm may bring about significant visual function improvement, whereas erroneous diagnosis may result in irreversible visual loss, neurological dysfunction or death. The causes of compression of the anterior visual pathway are incredibly varied. Meningiomas, pituitary tumors and aneurysms are the lesions most commonly identified as causes of compressive optic neuropathy without disc edema. A case is presented of a female 50-year-old patient undergoing congenital cataract surgery of her left eye without visual function improvement, alongside unspecific visual quality worsening. Visual psychophysical testing, automated campimetry and optical coherence tomography contributed findings suggestive of intracranial visual pathway compression. Magnetic resonance imaging of the brain and orbits was indicated to confirm the diagnostic suspicion. Cerebral angiography revealed the presence of an internal carotid artery aneurysm which was treated by endovascular procedure with satisfactory results(AU)

ABSTRACT

Adulto jovem de 18 anos que evoluiu após traumatismo craniencefálico leve com fístula carotídea direta. Apresentou zumbido e exoftalmia, ambos de característica pulsátil e à esquerda. Foi submetido a estudo com Doppler das carótidas, que mostrou elevadas velocidades do fluxo sanguíneo e índices de resistência reduzidos nas artérias carótidas comum e interna esquerdas, compatíveis com fístula carotídea direta. A angiotomografia computadorizada cerebral confirmou a fístula carotídea. Foi encaminhado para tratamento endovascular por embolização, com sucesso. O Doppler de carótidas pode ter papel importante no diagnóstico das fístulas carotídeas diretas e acompanhamento de pacientes submetidos à terapêutica endovascular.(AU)

ABSTRACT

Resumen Introducción: Los aneurismas aislados de arteria ilíaca común son una patología infrecuente y habitualmente el diagnóstico es incidental. Su manejo solía ser por vía abierta, pero con el advenimiento de la cirugía endovascular, se han identificado mejores desenlaces en los pacientes llevados a este tipo de procedimientos, reservando la reparación abierta en los casos agudos y rupturas. La asociación entre estos aneurismas con fístulas ílio-ilíacas son infrecuentes y su manejo endovascular se ha reportado en solo una ocasión. Objetivo: Se presenta un caso de un paciente masculino de 82 años, con esta asociación, en el cual se decidió llevar de manera electiva a manejo endovascular de su patología. Discusión: En la literatura el manejo endovascular es ampliamente recomendado por su perfil de seguridad, sin embargo, no existe suficiente evidencia ante la presencia de una fístula ílio-ilíaca de manera concomitante, por ser una condición infrecuente. Conclusión: En el presente caso, abordamos de manera endovascular esta relación, obteniendo resultados favorables, con adecuado control de la patología, sin presentación de complicaciones.


Introduction: The isolated aneurysms of the common iliac artery correspond to an infrequent pathology; and the diagnosis of this entity is usually incidental. Its management is usually by open route, but with the advent of endovascular surgery, better outcomes have been identified in patients taken to this kind of procedure, reserving open repair for the urgent cases, like ruptures. The association between these aneurysms with ilio-iliac fistula is uncommon and their endovascular management has been reported only in one case in the literature. Aim: A case of an 82-year-old male patient will be presented, with this association, who was taken to an endovascular repair of his pathology, with good postoperative results. Discussion: In the literature, endovascular management is recommended by its safety profile, however there is insufficient evidence in the presence of an ilio-iliac fistula concomitantly, because it is an infrequent condition. Conclusion: In the present case, we address this relationship endovascularly, obtaining favorable results, with adequate control of the pathology, without presenting any complications.

ABSTRACT

La terapia endovascular (TEV) es el tratamiento estándar del ataque cerebrovascular isquémico (ACVi) con oclusión de gran vaso (OGVC). Aún no se conoce si esos resultados pueden generalizarse a la práctica diaria. Se describen los resultados de la TEV en pacientes con ACVi por OGVC dentro de las 24 horas, en un análisis retrospectivo entre enero 2013 y diciembre 2017 que incluyó 139 casos consecutivos con ACVi y OGVC en arteria cerebral media (ACM), hasta 24 horas del inicio de los síntomas, que recibieron TEV en nuestra institución. El resultado primario medido fue la escala de Rankin modificada (mRS) ≤ 2 a 90 días. Se evaluaron también: reperfusión exitosa, según la escala modificada de trombólisis en infarto cerebral (mTICI) 2b/3, hemorragia intracraneal sintomática (HIS) y mortalidad a 90 días. La edad media: 67.5 ± 15.0, siendo el 51.8% mujeres. La mediana basal de National Institute of Health Stroke Scale (NIHSS) fue 14 (IIC 8-18); la mediana del tiempo desde inicio de síntomas hasta punción inguinal: 331 min (IIC 212-503). El 45.3%, 63 pacientes, fueron tratados > 6 horas después del inicio de síntomas. La tasa de mRS ≤ 2 fue 47.5%. Se logró una reperfusión exitosa en el 74.8%. La tasa de mortalidad a 90 días fue del 18.7% y la HIS del 7.9%. Nuestro registro de pacientes de la vida real con ACVi por OGVC tratados con TEV dentro de las 24 horas mostró altas tasas de reperfusión, buenos resultados funcionales y pocas complicaciones, acorde con las recomendaciones internacionales.


Endovascular treatment (EVT) has become the standard of care for acute ischemic stroke (AIS) with proximal large vessel occlusions (LVO). However, it is still unknown whether these results can be generalized to clinical practice. We aimed to perform a retrospective review of patients who received EVT up to 24 hours, and to assess safety and efficacy in everyday clinical practice. We performed a retrospective analysis, from January 2013 to December 2017, on 139 consecutive patients with AIS for anterior circulation LVO strokes up to 24 h from symptoms onset, who received EVT in our institution. The primary outcome measured was a modified Rankin scale (mRS) ≤ 2 at 90 days. Secondary outcomes included successful reperfusion, defined as a modified Thrombolysis in Cerebral Infarction (mTICI) scale 2b/3, mortality rate at 90 days and symptomatic intracranial hemorrhage (sICH). The mean age was 67.5 ± 15.0, with 51.8% female patients. Median baseline National Institute of Health Stroke Scale (NIHSS) was 14 (IQR 8-18); median time from symptom onset to groin puncture was 331 min (IQR 212-503). Sixty-three patients (45.3%) were treated beyond 6 hours after symptoms onset. The rate of mRS ≤ 2 was 47.5%. Successful reperfusion was achieved in 74.8 %. Mortality rate at 90 days was 18.7 % and sICH was 7.9 %. Our registry of real-life patients with AIS due to LVO who received EVT within 24 hours showed high reperfusion rates, and good functional results with few complications, according to international recommendations.

ABSTRACT

El síndrome de Klippel-Trenaunay-Weber (SKTW) es una rara malformación venosa que, en general afecta a los miembros inferiores y, más raramente, a los superiores. Se caracteriza por formaciones angiomatosas cutáneas, várices e hipertrofia del miembro afectado. El compromiso genitourinario es sumamente infrecuente. Se presenta el caso de una paciente de 14 años. Ingresó por hematuria macroscópica de 48 h de evolución y metrorragia con grave compromiso hemodinámico. Se encontraba en estudio por presentar un hemangioma en el miembro inferior izquierdo que se extendía hasta la región pelviana. La uretrocistofibroscopía demostró la presencia de múltiples lesiones angiomatosas diseminadas en forma amplia en la vejiga, algunas de ellas con sangrado activo. La angioresonancia mostró una voluminosa formación hipervascularizada en contacto con la pared vesical a la cual desplazaba y fístulas arteriovenosas a nivel pelviano y en el miembro inferior izquierdo confirmando el diagnóstico etiológico. Se realizó una embolización arterial selectiva de los territorios ilíacos interno y externo e inmediatamente después una endocoagulación láser de los focos angiomatosos sangrantes. La hematuria remitió completamente en las 24 h posteriores al procedimiento. La metrorragia asociada al SKTW fue controlada mediante la utilización de análogos LHRH y progestágenos.


Klippel-Trenaunay-Weber syndrome (KTWS) is a rare venous malformation that generally affects the lower limbs and, more infrequently, the upper limbs. It is characterized by cutaneous angiomatous formations, varicose veins and hypertrophy of the affected limb. The involvement of the genitourinary tract is extremely infrequent. We expose the case of a 14 years old female patient who was admitted for macroscopic hematuria of 48 hours of evolution and metrorrhagia with severe hemodynamic decompensation. The patient was under study for presenting a hemangioma in the lower left limb that extended to the pelvic region. Urethrocystofibroscopy showed the presence of multiple wide-spread angiomatous lesions in the bladder, some of them with active bleeding. The angio-resonance showed a voluminous hypervascular formation in contact with the bladder wall showing several arteriovenous fistulas at the pelvic level and in the left lower limb confirming the etiological diagnosis. A selective arterial embolization of the internal and external iliac territories was performed and then, a laser endocoagulation of the bleeding angiomatous foci was carried out. The hematuria completely stopped within 24 hours later of the procedure. The metrorrhagia associated with KTWS was controlled by the use of LHRH analogs and progestogens.

ABSTRACT

BACKGROUND@#Although endovascular therapy has been widely used for focal aortoiliac occlusive disease (AIOD), its performance for extensive AIOD (EAIOD) is not fully evaluated. We aimed to demonstrate the long-term results of EAIOD treated by endovascular therapy and to identify the potential risk factors for the loss of primary patency.@*METHODS@#Between January 2008 and June 2018, patients with a clinical diagnosis of the 2007 TransAtlantic Inter-Society Consensus II (TASC II) C and D AIOD lesions who underwent endovascular treatment in our institution were enrolled. Demographic, diagnosis, procedure characteristics, and follow-up information were reviewed. Univariate analysis was used to identify the correlation between the variables and the primary patency. A multivariate logistic regression model was used to identify the independent risk factors associated with primary patency. Five- and 10-year primary and secondary patency, as well as survival rates, were calculated by Kaplan-Meier analysis.@*RESULTS@#A total of 148 patients underwent endovascular treatment in our center. Of these, 39.2% were classified as having TASC II C lesions and 60.8% as having TASC II D lesions. The technical success rate was 88.5%. The mean follow-up time was 79.2 ± 29.2 months. Primary and secondary patency was 82.1% and 89.4% at 5 years, and 74.8% and 83.1% at 10 years, respectively. The 5-year survival rate was 84.2%. Compared with patients without loss of primary patency, patients with this condition showed significant differences in age, TASC II classification, infrainguinal lesions, critical limb ischemia (CLI), and smoking. Multivariate logistic regression analysis showed age <61 years (adjusted odds ratio [aOR]: 6.47; 95% CI: 1.47-28.36; P = 0.01), CLI (aOR: 7.81; 95% CI: 1.92-31.89; P = 0.04), and smoking (aOR: 10.15; 95% CI: 2.79-36.90; P < 0.01) were independent risk factors for the loss of primary patency.@*CONCLUSION@#Endovascular therapy was an effective treatment for EAIOD with encouraging patency and survival rate. Age <61 years, CLI, and smoking were independent risk factors for the loss of primary patency.

ABSTRACT

ABSTRACT Endovascular treatment for femoropopliteal arterial disease has made revascularization procedures less invasive, but the self-expanding stents used can suffer great wear in arteries with extreme mobility. Objective: to evaluate the prevalence of fractures in stents implanted in the femoropopliteal segment, to identify predisposing factors and consequences on arterial patency. Method: between March and June 2019, thirty patients previously operated for femoropopliteal obstruction underwent stent X-rays in anteroposterior and lateral views to detect fractures and Doppler to analyze arterial patency. Results: we observed 12 cases with fractures (33.3%): 1 type I (2.8%), 3 type II (8.3%), 5 type III (13.9%), 3 type IV (8.3%) and no type V. According to the TASC II we had 1 in group B (8.3%), 6 in group C (50%) and 5 in group D (41.6%) p <0.004. The number of stents per limb was 3.1 (± 1.3) in cases of fracture versus 2.3 (± 1.3) in cases without fracture (p = 0.08). The extension was 274.17mm (± 100.94) in cases of fracture and 230.83mm (± 135.44) in cases without fracture (p = 0.29). On Doppler we had: 17 patients (47.2%) without stenosis, 9 patients (25%) with stenosis> 50% and 10 patients (27.8%) with occlusion (p = 0.37). There was no correlation between fracture and arterial obstruction (p = 0.33). Conclusion: stent fractures are a frequent finding in the femoropopliteal area (33.3%), being more prevalent in cases of more advanced disease (C and D). There was no association between the finding of fracture and arterial obstruction.


RESUMO Os tratamentos endovasculares para a doença arterial obstrutiva fêmoro-poplítea tornaram os procedimentos de revascularização menos invasivos, porém os stents metálicos autoexpansíveis utilizados podem sofrer grande desgaste em artérias com extrema mobilidade. Objetivo: avaliar a prevalência de fraturas em stents implantados no segmento fêmoro-poplíteo, identificar fatores predisponentes e possíveis consequências sobre a patência arterial. Métodos: entre março a junho de 2019, trinta pacientes previamente operados por obstrução fêmoro-poplítea realizaram RX dos stents em incidências ântero-posterior e perfil para detectar fraturas e eco Doppler para analisar a patência arterial. Resultados: observamos 12 casos com fraturas (33,3%): 1 do tipo I (2,8%), 3 do tipo II (8,3%), 5 do tipo III (13,9%), 3 do tipo IV (8,3%) e nenhuma tipo V. Segundo a classificação TASC II, tivemos 1 no grupo B (8,3%), 6 no grupo C (50%) e 5 no grupo D (41,6%) p<0,004. O número de stents por membro foi de 3,1 (±1,3) nos casos de fratura contra 2,3 (±1,3) nos casos sem fratura (p = 0,08). A extensão tratada foi 274,17mm (±100,94) nos casos de fratura e 230,83mm (±135,44) nos casos sem fratura (p=0,29). No Doppler tivemos: 17 pacientes (47,2%) sem estenose, 9 pacientes (25%) com estenose>50% e 10 pacientes (27,8%) com oclusão (p=0,37). Não houve correlação entre fratura e obstrução arterial (p=0,33). Conclusão: as fraturas de stents são um achado frequente no setor fêmoro-poplíteo (33,3%) sendo mais prevalentes nos casos de doença mais avançada TASC II C e D. Não houve associação entre o achado de fratura e obstrução arterial.

ABSTRACT

Resumen Objetivo: Presentar un caso clínico infrecuente, con una resolución novedosa. Caso Clínico: Paciente con aneurisma micótico de la arteria mesentérica superior manejado satisfactoriamente en forma endovascular. Los aneurismas micóticos viscerales son entidades infrecuentes, con alta morbimortalidad. Es por ello que su manejo debe ser multidisciplinario y considerar diferentes factores al momento de tomar decisiones. En el contexto de la continua mejoría y disponibilidad de las técnicas endovasculares, estas han emergido como una opción terapéutica válida, con posiblemente menos complicaciones. Conclusión: La resolución endovascular del aneurisma micótico visceral es factible, pero su indicación y el manejo completo es aún caso a caso.


Objective: to discuss an infrequent vascular case with a novel resolution. Case Report: Superior mesenteric artery mycotic aneurysm successfully managed with coil embolization. A visceral mycotic aneurysm is an infrequent vascular pathology with high risk of complications and mortality. The endovascular management might offer a treatment option with lower morbimortality rates in selected cases. Conclusion: Endovascular resolution of mycotic visceral aneurysms is both feasible and secure but it must be done in a case to case basis.

ABSTRACT

Abstract Regardless the successful treatment of the descending aorta with endovascular prosthesis, for the ascending aorta segment, because of several anatomic and physiologic issues, this technique has been considered an alternative only for high-risk or inoperable patients. Despite restricted indications, hundreds of treatments have been performed worldwide, demonstrating its safety and reproducibility if it is done in high-quality centers. Therefore, understanding patients' selection criteria and technique limitations are critical to its application.

ABSTRACT

Los aneurismas del cayado aórtico representan un desafío, ya que el involucramiento de sus grandes ramas exige una técnica quirúrgica compleja. A partir de la aparición del tratamiento endovascular, una alternativa desarrollada en los últimos años para abordar el cayado aórtico consistió en el tratamiento híbrido de esta patología, mediante la derivación quirúrgica de los vasos del cuello y la posterior exclusión del aneurisma con una endoprótesis. Este método híbrido es conocido con el nombre de debranching, y en forma simplificada consiste en realizar, sin circulación extracorpórea, una serie de puentes entre la aorta ascendente y el tronco braquiocefálico, la arteria carótida izquierda y eventualmente la arteria subclavia izquierda, para permitir avanzar una endoprótesis que cubra toda la luz del aneurisma. Se describe la técnica quirúrgica del debranching híbrido tipo I, sin el auxilio de la circulación extracorpórea e implante anterógrado de la endoprótesis, para los aneurismas del cayado aórtico.


Aortic arch aneurysms represent a major challenge as the involvement of the supra-aortic vessels demands a complex surgical technique. Since the advent of endovascular aortic repair, hybrid treatment of aortic arch disease has emerged in recent years. The procedure consists of surgical bypass of the supra-aortic vessels followed by exclusion of the aneurysm with an endograft. This hybrid method is known as debranching and, briefly, consists in performing bypasses between the ascending aorta and the brachiocephalic artery, the left carotid artery and possibly the left subclavian artery without cardiopulmonary bypass, in order to advance an endograft to cover the entire lumen of the aneurysm. The aim of this paper is to describe the surgical technique of type I hybrid debranching without cardiopulmonary bypass and antegrade endograft delivery to treat aortic arch aneurysms.

ABSTRACT

ABSTRACT The treatment of cryptogenic stroke patients with a patent foramen ovale (PFO) is controversial. A critical review of these studies is presented. Methods A description of all trials comparing medical and endovascular treatment with closing devices is given. Additional pertinent studies are discussed to help construct a rational basis for treatment decisions. Results Initial negative trials evaluating PFO closure were followed by positive studies published in 2017 and 2018. All trials evaluated young patients (up to 60 years). Methodological problems are present in all trials including their open label construction. Most positive trials developed strategies to increase the percentage of patients with interatrial septal aneurysms or hypermobility and large right-to-left shunts. Even in these positive trials, large numbers of patients need to be treated to avoid one stroke. Atrial fibrillation occurred in 2-6% and other adverse effects related to the procedure and to the devices occurred in a substantial number of patients. Incomplete occlusion of the PFO is also frequent. Anticoagulant treatment has not been adequately studied as a therapeutic option. Conclusion Young patients with cryptogenic strokes seem to benefit from endovascular closure of a PFO in the presence of a large right-to-left shunt or an associated atrial septum aneurysm. For most other patients, a highly-individualized decision must be made, taking into account the low risk of recurrence in patients with a cryptogenic stroke attributable to a PFO, the high numbers needed to treat and the risks related to the procedure.


RESUMO O tratamento de pacientes com infarto cerebral criptogênico e forame oval patente (FOP) é controverso. Uma revisão crítica destes estudos é apresentada. Métodos São descritos em detalhes os estudos comparando tratamento médico com o uso de próteses de oclusão do FOP após infarto cerebral. Discutem-se outros estudos pertinentes para ajudar na tomada racional de decisões terapêuticas individualizadas. Resultados Estudos iniciais avaliando fechamento endovascular com próteses foram negativos, porém seguidos de outros estudos com resultados positivos em 2017 e 2018. Somente pacientes até 60 anos foram estudados. Os estudos apresentam vários problemas metodológicos, incluindo sua natureza aberta. A maioria dos estudos positivos desenvolveu estratégias para aumentar o percentual de pacientes com risco aumentado de recorrência, especificamente grandes shunts direita-esquerda e aneurismas/hipermobilidade do septo interatrial. Mesmo estes estudos positivos revelaram um alto NNT (número de pacientes tratados para evitar um evento de desfecho). Fibrilação atrial ocorreu em 2-6 % dos pacientes tratados. Outras complicações relacionadas ao procedimento e às endopróteses e ainda fechamento incompleto do FOP foram também frequentes. Anticoagulantes poderiam constituir estratégia alternativa de tratamento clínico, mas não foram adequadamente estudados. Conclusão Pacientes jovens com infartos criptogênicos parecem beneficiar-se de oclusão endovascular do FOP na presença de grandes shunts e principalmente aneurismas ou hipermobilidade de septo interatrial. Para a maioria dos outros pacientes, uma decisão altamente individualizada deve ser tomada, considerando o baixo risco de recorrência dos infartos atribuíveis ao FOP, o ato NNT e os riscos inerentes ao procedimento.

ABSTRACT

Resumen Introducción: Los aneurismas infecciosos constituyen una patología poco frecuente y se caracterizan por presentar infección de la pared del vaso implicado. El mejor tratamiento no está definitivamente establecido. Objetivo: Describir un caso de aneurisma infeccioso con manejo endovascular. Caso clínico: Presentamos un paciente de sexo masculino de 75 años que ingresa por cuadro compatible con abdomen agudo y que en el posoperatorio se pesquisa un aneurisma infeccioso del tronco celíaco, el cual se trata mediante una endoprótesis y manejo antibiótico. Discusión: El manejo tradicional del aneurisma infeccioso es la cirugía abierta que incluye la extirpación o exclusión del aneurisma y de su tejido perivascular infectado, pero conlleva gran morbimortalidad. Conclusión: El aneurisma infeccioso puede ser manejado de forma mínimamente invasiva con técnica endovascular, con baja morbilidad inmediata, pero con resultados a largo plazo aun no concluyentes.


Introduction: Infectious aneurysms are a rare disease and are characterized by infection of the involved vessel wall. The best treatment is definitely not established. Aim: To describe a case of infectious aneurysm with endovascular management. Case report: We present a 75-year-old male patient admitted to a table compatible with acute abdomen and that an infectious aneurysm of the celiac trunk is investigated in the postoperative period, treated with an endoprosthesis and antibiotic management. Discussion: The traditional management of the infectious aneurysm is open surgery that includes the removal or exclusion of the aneurysm and its infected perivascular tissue, but it leads to great morbidity and mortality. Conclusion: The infectious aneurysm can be managed minimally invasively with endovascular technique, with immediate low morbidity, but with long-term results that are still inconclusive.

ABSTRACT

Abstract Background and objectives Ultrasound-guided internal jugular vein catheterization is a common and generally safe procedure in the operating room. However, inadvertent puncture of a noncompressible artery such as the subclavian artery, though rare, may be associated with life-threatening sequelae, including hemomediastinum, hemothorax, and pseudoaneurysm. Case report We describe a case of the successful endovascular repair of right subclavian artery injury in a 75-year-old woman. Subclavian artery was injured secondary to ultrasound-guided right internal jugular vein catheterization under general anesthesia for orthopedic surgery. Conclusion Under general anesthesia several factors such as hypotension can mask the signs of subclavian artery injury. This case report indicates that clinicians should be aware of the complications of central venous catheterization and take prompt action.


Resumo Justificativa e objetivos A cateterização da veia jugular interna guiada por ultrassom é um procedimento comum e geralmente seguro em sala cirúrgica. No entanto, a punção inadvertida de uma artéria não compressível, como a artéria subclávia, embora rara, pode estar associada a sequelas e risco para vida, incluindo hemomediastino, hemotórax e pseudoaneurisma. Relato de caso Descrevemos um caso bem-sucedido da correção endovascular de lesão da artéria subclávia direita em uma paciente de 75 anos. A artéria subclávia foi lesionada após cateterização guiada por ultrassom da veia jugular interna direita sob anestesia geral para cirurgia ortopédica. Conclusão Sob anestesia geral, vários fatores, como a hipotensão, podem mascarar os sinais de lesão da artéria subclávia. Este relato de caso indica que os médicos devem estar cientes das complicações da cateterização venosa central e tomar medidas imediatas.

ABSTRACT

Objetivo: La arteria subclavia aberrante (ASA) o arteria lusoria, es una de las malformaciones más comunes del arco aórtico; en especial su variante derecha. Por otro lado, la arteria subclavia aberrante izquierda es más rara. Presentamos un caso infrecuente de un paciente con síndrome deleción 22q11.2 y ASA izquierda con síntomas en extremidad superior izquierda. La ASA izquierda es una condición muy poco frecuente y hay escasa información sobre su tratamiento quirúrgico. La mayoría de las veces, el ASA es asintomática; especialmente en adultos. Si presenta clínica, sus síntomas son disfagia, tos, disnea, claudicación de la extremidad superior. La presencia de sintomatología es una indicación quirúrgica. El tratamiento quirúrgico de una ASA es discutido. Éste va a depender de la anatomía, comorbilidades y experiencia del cirujano.


Objective: The Aberrant Right Subclavian Artery (ARSA) or Lusoria Artery is one of the most common aortic arch malformations. Aberrant Left Subclavian Artery (ALSA) on the other hand, is a much rarer condition. We present an uncommon case of ALSA in a patient with 22q11.2 deletion syndrome with upper limb symptoms and review the treatment options. ALSA is an exceedingly rare condition and information on its surgical treatment is scarce. In most cases the presence of an ALSA is asymptomatic, especially in adults. Some of the most typical symptoms are dysphagia (dysphagia lusoria), cough, dyspnea, claudication of the upper limb extremity. When symptomatic, the patient has indication of surgery. The treatment of an ALSA is still debatable and it depends on the anatomy, comorbidities and surgeon´s experience.

ABSTRACT

INTRODUCCIÓN: El trauma vascular es un evento de baja frecuencia, con alta morbimortalidad que afecta la población joven; requiere en general un manejo quirúrgico. Se asocia a complicaciones desde la reintervención quirúrgica hasta la amputación de la extremidad, influenciado por variables tanto asociadas al trauma como a la atención hospitalaria. OBJETIVO: Determinar los factores de riesgo relacionados con amputación, en pacientes con trauma arterial periférico (TAP), atendidos en un Hospital de III nivel Huila- Colombia entre 2014-2017. MATERIALES Y MÉTODOS: Estudio observacional, analítico de corte retrospectiva con pacientes mayores de 13 años con TAP. RESULTADOS: Se incluyeron 79 pacientes, con un 1,56% de las consultas en nuestro Servicio de Urgencia. 89% hombres, promedio de edad 28,5 años. La principal comorbilidad fue la farmacodependencia 8,8%. El MESS (mangled extremity severity) promedio fue de 5,27 puntos y un tiempo critico de isquemia de extremidad > a 6 horas en el 38%. El mayor compromiso fue de miembros superiores, secundario a heridas por arma cortopunzante. La lesión predominante fue la transección arterial. Las principales complicaciones posquirúrgicas fueron la trombosis del vaso (21,5%) y la amputación (13,9%). Factores de riesgo asociados a amputación fueron la edad > 20 años, estancia hospitalaria > 7 días, MESS > 7 puntos, que presentaran como complicación quirúrgica la trombosis arterial y que requirieran reintervención quirúrgica. CONCLUSIONES: El trauma arterial periférico es una patología con gran repercusión socioeconómica y secuelas funcionales. Es necesaria la atención oportuna con tratamiento de las variables relacionadas con mal pronóstico, con el fin de disminuir las tasas de morbimortalidad.


INTRODUCTION: Vascular trauma is a low frequency event, with high morbidity and mortality that affects the young population; In general, it requires surgical management. It is associated with complications from surgical reintervention to amputation of the limb, influenced by trauma associated variables such as hospital care. AIM: Determine risk factors related to amputation, in patients with peripheral arterial trauma (TAP), treated at a Hospital of III level Huila-Colombia between 2014-2017. MATERIALS AND METHOD: Observational, retrospective analytical study with patients older than 13 years with TAP. RESULTS: We included 79 patients with an incidence of 1.56%. 89% men, average age 28.5 years. The main comorbidity was 8.8% drug dependence. The MESS (Mangled extremity severity) average was of 5.27 points and a critical time of limb ischemia > to 6 hours in 38%. The greater commitment was of superior members, secondary to injuries by sharp weapon. The predominant lesion was arterial transection. The main postoperative complications were vessel thrombosis (21.5%) and amputation in 13.9%. Risk factors associated with amputation were determined by age > 20 years, hospital stay > 7 days, MESS > 7 points, and that they presented arterial thrombosis as a surgical complication and finally required surgical reoperation. CONCLUSIONS: Peripheral arterial trauma is a pathology with great socioeconomic impact and functional sequelae. It is necessary the timely attention with treatment of the variables related to poor prognosis, in order to decrease the morbidity and mortality rates.

ABSTRACT

Abstract Objective: The purpose of this study was to compare the operative mortality rate and outcomes of endovascular aneurysm repair (EVAR) between young and geriatric people in a single center. Methods: Eighty-five patients with abdominal aortic aneurysms who underwent EVAR between January 2012 and September 2016 were included. Outcomes were compared between two groups: the young (aged < 65 years) and the geriatric (aged ≥ 65 years). The primary study outcome was technical success; the secondary endpoints were mortality and secondary interventions. The mean follow-up time was 36 months (3-60 months). Results: The study included 72 males and 13 females with a mean age of 71.08±8.6 years (range 49-85 years). Of the 85 patients analyzed, 18 (21.2%) were under 65 years old and 67 patients (78.8%) were over 65 years old. There was no statistically significant correlation between chronic disease and age. We found no statistically significant difference between aneurysm diameter, neck angle, neck length, or right and left iliac angles. The secondary intervention rate was 7% (six patients). The conversion to open surgery was necessary for only one patient and only three deaths were reported (3.5%). There was no statistically significant difference in the mortality and reintervention rates between the age groups. The three deaths occurred only in the geriatric group and two died secondary to rupture. Kidney failure was observed in three patients in the geriatric group (4.5%). Conclusion: Our single-center experience shows that EVAR can be used safely in both young and geriatric patients.

ABSTRACT

SUMMARY Background: To compare the treatment efficacy of different types of endovascular mechanical embolectomy in acute ischemic stroke (AIS). Material and Methods: A total of 89 patients with AIS were selected in our hospital from January 2014 to January 2016 and divided into tPA group (n=27), tPA+Trevo group (n=30) and tPA+Solitaire FR group (n=32) for different treatments. Treatment effectiveness was evaluated using NIHSS and mRS system. The NIHSS score, vascular recanalization rate and postoperative complications were compared among groups. Results: The NIHSS score of the tPA group was significantly lower than that of other two groups at 1 d after the operation (p < 0.05), but it was significantly higher than that of other two groups at 3 d and 3 w after the operation (p < 0.05). After the treatment, no significant difference in NIHSS score was found between the tPA+Trevo and tPA Solitaire FR groups. The revascularization rate was significantly higher, but the mortality rate in 90 d was significantly lower in the tPA+Trevo and tPA+Solitaire FR groups than that in the tPA group (p < 0.05), and no significant difference was found between the tPA+Trevo and tPA+Solitaire FR groups. The incidence rate of symptomatic intracranial hemorrhage was significantly lower in the tPA+Solitaire FR group than that in tPA+Trevo group (p < 0.05) or tPA group (p < 0.01). Significantly more patients with mRS no higher than 2 points were found in the tPA+Trevo and tPA+Solitaire FR groups than those in tPA group (p < 0.05), and no significant difference was found between the tPA+Trevo and tPA+Solitaire FR groups. Conclusion: TPA+Solitaire FR is a type of thrombectomy that is superior to tPA and tPA+Trevo in the treatment of patients with AIS.


RESUMO OBJETIVO Comparar a eficácia do tratamento de diferentes tipos de embolectomia mecânica endovascular em acidente vascular cerebral isquêmico agudo (AIS). MATERIAL E MÉTODOS Um total de 89 pacientes com AIS foi selecionado em nosso hospital de janeiro de 2014 a janeiro de 2016, e os pacientes foram divididos em: grupo tPA (n = 27), tPA + grupo Trevo (n = 30) e grupo tPA + Solitaire FR (n = 32) para diferentes tratamentos. A eficácia do tratamento foi avaliada usando NIHSS e sistema mRS. Escore NIHSS, taxa de recanalização vascular e complicações pós-operatórias foram comparados entre os grupos. RESULTADOS A pontuação NIHSS do grupo tPA foi significativamente menor do que a dos outros dois grupos em um dia após a operação (p < 0,05), mas foi significativamente maior do que nos outros dois grupos em três dias e três semanas após a operação (p < 0,05). Após o tratamento, não houve diferença significativa no escore NIHSS entre o grupo tPA + Trevo e o grupo tPA Solitaire FR. A taxa de revascularização foi significativamente maior, mas a taxa de mortalidade em 90 dias foi significativamente menor nos grupos tPA + Trevo e tPA + Solitaire FR do que no grupo tPA (p < 0,05) e não houve diferença significativa entre os grupos tPA + Trevo e tPA + Solitaire FR. A taxa de incidência de hemorragia intracraniana sintomática foi significativamente menor no grupo tPA + Solitaire FR do que no grupo tPA + Trevo (p < 0,05) ou no grupo tPA (p < 0,01). Significativamente mais pacientes com mRS não maiores que 2 pontos foram encontrados no grupo tPA + Trevo e tPA + Solitaire FR do que no grupo tPA (p < 0,05), e nenhuma diferença significativa foi encontrada entre os grupos tPA + Trevo e tPA + Solitaire FR. Conclusão O tPA + Solitaire FR é um tipo de trombectomia superior ao tPA e tPA + Trevo no tratamento de pacientes com EIA.

ABSTRACT

SUMMARY OBJECTIVE: Aortic dissecting aneurysms involving visceral arteries are difficult for clinical treatment. This study aimed to explore the clinical efficacy and safety of multi-layer bare stents technique in the treatment of aortic dissecting aneurysms involving visceral arteries. METHOD: The clinical data of 16 patients of aortic dissecting aneurysm involving visceral artery treated with multi-layer bare stents technique from March 2013 to March 2017 in Tianjin Medical University General Hospital were retrospectively analyzed. To explore the clinical efficacy, the number of stents applied, postoperative aortic dissecting thrombosis and postoperative cumulative branch arterial patency of the16 patients. RESULTS: The operations of the 16 patients were successfully completed without peri-operative death cases. The 16 patients were implanted with 39 bare stents with an average of 2.44 per person. There were 2 cases with 1 stent, 8 cases with 2 stents and 7 cases with 3 stents. One month after the operation, CTA showed complete thrombosis in the arterial dissection in 4 cases (25.0%), partial thrombosis in 12 cases (75.0%); CTA showed that celiac artery, left and right renal arteries, and superior mesenteric artery were all unobstructed. There were 4 cases (25.0%) of dissecting artery with reduced diameter, 12 patients (75.0%) without changes in the diameter, and no diameter expanding cases. CONCLUSION: The treatment for aortic dissecting aneurysm involving the visceral arteries using multi-layer bare stents technique is safe and reliable with a higher patency rate of postoperative accumulated branch arteries.


RESUMO Objetivo: Aneurismas dissecantes da aorta envolvendo artérias viscerais são de difícil tratamento clínico. O objetivo deste estudo foi explorar a eficácia e segurança clínica da técnica de stents multicamadas não farmacológicos para o tratamento de aneurismas dissecantes da aorta envolvendo artérias viscerais. Métodos: Foi feito um estudo retrospectivo usando os dados de 16 pacientes com aneurisma dissecante da aorta envolvendo artérias viscerais e tratados com stents multicamadas não farmacológicos de março de 2013 a março de 2017, do Hospital da Escola de Medicina da Universidade de Tianjin. Foram analisados nos 167 pacientes: a eficácia clínica, o número de stents aplicados, trombose dissecante da aorta no pós-operatório e patência cumulativa pós-operatória do ramo arterial. Resultados: As operações dos 16 pacientes foram concluídas com sucesso sem nenhum óbito perioperatório. Os 16 pacientes receberam 39 stents não farmacológicos, com uma média de 2,44 por indivíduo. Houve 2 casos com 1 stent, 8 com 2 stents, e 7 com 3. Um mês após a operação, a ATC mostrou trombose completa da dissecção arterial em 4 casos (25,0%) e trombose parcial em 12 casos (75%). Também mostrou que a artéria celíaca, as artérias renais direita e esquerda e a artéria mesentérica superior estavam todas desobstruídas. Houve 4 casos (25,0%) de artéria dissecante com diâmetro reduzido, 12 (75,0%) pacientes sem alteração no diâmetro, e nenhum caso de aumento de diâmetro. Conclusão: O tratamento para aneurisma dissecante da aorta envolvendo artérias viscerais com a técnica de stents não farmacológicos multicamadas é seguro e confiável, com uma taxa mais alta de patência de ramos arteriais acumulados no pós-operatório.

ABSTRACT

RESUMO A oclusão ressuscitativa por balão endovascular da aorta (REBOA) é utilizada para controlar hemorragias não compressíveis do tronco como uma opção menos invasiva e com menos distúrbios fisiológicos quando comparado à toracotomia de emergência com clampeamento da aorta. Isso permite a melhora dos parâmetros hemodinâmicos até que a cirurgia definitiva seja realizada. É utilizada no trauma como uma medida para prevenir o colapso hemodinâmico em pacientes que estão em choque hemorrágico grave, mantendo a perfusão do cérebro e do coração enquanto diminui o sangramento distal até que o controle da hemorragia possa ser realizado. As principais complicações relatadas são insuficiência renal aguda, amputações de membros inferiores e óbitos. O objetivo desse estudo foi avaliar a expansão do uso do REBOA em situações não traumáticas de outras áreas da medicina, assim como, avaliar os resultados obtidos até o momento. Uma pesquisa online do PubMed, Medline e SciELO foi realizada com o termo "REBOA" nos últimos cinco anos, e os artigos incluídos foram os 14 que descrevem especificamente o uso do REBOA para condições não traumáticas. Os resultados sugerem que o uso do REBOA levou a um melhor controle do sangramento e aumento da pressão arterial, reduzindo a necessidade de transfusão de sangue e permitindo que os pacientes sobrevivam ao tratamento definitivo das lesões. Concluindo, o uso expandido do REBOA para emergências não traumáticas parece ser eficaz, mas estudos prospectivos e protocolos bem estabelecidos devem ser desenvolvidos para maximizar os resultados.


ABSTRACT Currently, resuscitative endovascular balloon occlusion of the aorta (REBOA) is used in trauma surgery for controlling non-compressible torso hemorrhages, as a less invasive option and with fewer physiologic disturbances compared with an invasive emergent thoracotomy for aortic cross-clamping. This can allow improvements in hemodynamic parameters until definitive surgery is performed. REBOA is also used in trauma to prevent hemodynamic collapse in patients who are in severe hemorrhagic shock, as a method to maintain perfusion of the brain and heart while decreasing distal bleeding until hemorrhage control can take place. The major complications reported are acute kidney injury, lower leg amputations, and even death. As experience with REBOA in emergency surgery grows, new indications have been described in the literature. The aim of this study was to assess the expansion of the use of REBOA in other areas of medicine, as well as evaluating the current published series. We performed an online search of PubMed, Medline and SciELO with the term "REBOA" in the last five years, and the articles included were the 14 specifically describing the use of REBOA for non-traumatic conditions. The results suggest that the use of REBOA led to improved bleeding control and increased arterial pressure, reducing blood transfusion requirements and allowing patients to survive to definitive treatment of injuries. In conclusion, the expanded use of REBOA for non-traumatic emergencies appears to be effective. However, prospective studies and well-established protocols for specific indications should be developed to maximize patient outcomes.

ABSTRACT

A doença de Behçet (DB) é uma vasculite multissistêmica de etiologia desconhecida. O acometimento cardiovascular é bem descrito na literatura, sendo que a principal causa de morte na DB é secundária a complicações aneurismáticas. Relata-se aqui o caso de um paciente portador de DB com aneurisma de aorta abdominal reincidente, o qual foi corrigido por meio de endoprótese customizada. O tratamento ideal para portadores de DB ainda é bastante controverso e desafiador, tendo em vista as dificuldades técnicas e as recidivas frequentes. A intervenção endovascular apresenta-se como uma alternativa viável e consideravelmente menos mórbida do que a cirurgia convencional


Behçet's disease (BD) is a multisystemic vasculitis of unknown etiology. Cardiovascular involvement has been thoroughly described in the literature and the major cause of death in BD is secondary to aneurysm complications. In this case report, a patient with BD presented with a recurrent abdominal aortic aneurysm, which was corrected using a custom-made endoprosthesis. The optimal treatment for patients with BD remains highly controversial and challenging because of technical difficulties and frequent recurrence. Endovascular intervention seems to be a feasible alternative with considerably less morbidity than conventional surgery
