ABSTRACT

Objetivo: Determinar los hallazgos por eco-Doppler orbitario en pacientes con glaucoma primario de ángulo abierto según factores de riesgo aterosclerótico. Métodos: Se realizó un estudio observacional descriptivo y transversal en 300 órbitas de 150 pacientes con diagnóstico de glaucoma primario de ángulo abierto. A todos los casos se les realizó tonometría de contorno dinámico y tomografía de coherencia óptica. Se identificaron mediante interrogatorio y por el laboratorio clínico los factores de riesgo aterosclerótico: hipertensión arterial, tabaquismo, diabetes mellitus tipo 2, dislipidemia, obesidad y consumo excesivo de alcohol. Se les realizó ultrasonido orbitario y Doppler carotídeo, y solo en caso de resultar normales se procedió a evaluar mediante eco-Doppler las arterias oftálmica, central de la retina y ciliares posteriores temporales. Resultados: La edad media de los sujetos estudiados fue de 62,3 años. El 55,3 por ciento correspondió al sexo femenino y el 47,3 por ciento al color blanco de la piel. El número de factores de riesgo mostró una correlación lineal moderada, positiva y significativa con el índice de resistencia, mientras que con las velocidades dicha correlación resultó ser negativa. Todos los factores de riesgo expresaron efectos dañinos sobre la hemodinámica del flujo ocular, la presión intraocular y el grosor de las capas de fibras neurorretinianas temporales. Tras ajustar para la edad, esta negativa influencia continuó siendo relevante en la mayoría de los casos. Conclusiones: Los aspectos vasculares del glaucoma deben integrarse a la práctica clínica de esta afección, lo que ayudará a que el enfoque sea más completo, y redundará en un mejor pronóstico de la enfermedad(AU)


Objective: Determine the orbital echo-Doppler findings in patients with primary open angle glaucoma according to atherosclerotic risk factors. Methods: A cross-sectional observational descriptive study was conducted of 300 orbits of 150 patients diagnosed with primary open angle glaucoma. All the cases underwent dynamic contour tonometry and optical coherence tomography. Interrogation and clinical laboratory testing led to identification of the following atherosclerotic risk factors: arterial hypertension, smoking, diabetes mellitus type 2, dyslipidemia, obesity and excessive alcohol consumption. Orbital and carotid Doppler ultrasounds were performed, and only if they were normal they would be followed by echo-Doppler evaluation of the ophthalmic, central retinal and posterior temporal ciliary arteries. Results: Mean age of the study subjects was 62.3 years. 55.3 percent were female and 47.3 percent had white skin. The number of risk factors showed a moderate, positive and significant linear correlation with the resistive index, and a negative correlation with the velocities. All the risk factors expressed harmful effects on ocular flow hemodynamics, intraocular pressure and the thickness of temporal neuroretinal fibers. After adjusting for age, this negative influence continued to be relevant in most cases. Conclusions: The vascular aspects of glaucoma should be incorporated into the clinical management of this condition. This will make the approach more thorough and help achieve a better diagnosis(AU)

ABSTRACT

Introducción: La malformación aneurismática en la vena de Galeno es infrecuente, pero tiene alta mortalidad en neonatos. Objetivo: Examinar la relevancia clínica del diagnóstico ecográfico de la malformación aneurismática en la vena de Galeno Métodos: Investigación observacional, prospectiva y transversal realizado en el Cardiocentro William Soler. (noviembre 1999-diciembre 2016) La muestra la conformaron 18 neonatos con diagnóstico de malformación aneurismática en la vena de Galeno variedad coroidea mediante ecografía doppler. Se configuraron dos grupos de referencia: 1) 70 niños supuestamente sanos. 2) 73 niños con malformación de la vena Galeno de diferente naturaleza que la variante coroidea estudiada. El procesamiento de la información incluyó elementos de estadística inferencial y herramientas de la medicina basada en la evidencia. Resultados: La presencia de fallo cardíaco neonatal, signos electrocardiográficos de isquemia miocárdica y detección de soplo continuo transcraneal, fueron significativamente diferentes en el grupo de estudio en relación con el grupo de referencia (p= 0,000001), con predominio en el número de pacientes del grupo estudio en todas las variables. Los resultados anteriores conjugados con diversos hallazgos ecográficos: la dilatación anómala de la vena, exceso de vasculatura aferente, reducción de los índices circulatorios encefálicos e incremento en los diámetros vasculares supraaórticos, identificaron de forma precisa la malformación aneurismática en la vena de Galeno. La evaluación del riesgo relativo reafirmó la documentación de los hallazgos expuestos. Conclusiones: La ecografía doppler, por su relevancia clínica y vínculo con otros elementos diagnósticos, es mandatoria en la detección de la malformación aneurismática en la vena de Galeno(AU)


Introduction: Vein of Galen aneurysmal malformation is not frequent but it has high mortality rates in newborns. Objective: To assess the clinical relevance of ultrasound diagnosis of Vein of Galen aneurysmal malformation. Methods: Observational, prospective and cross-sectional research conducted in William Soler Cardiocentro (November 1999- December 2016). The sample was formed by 18 newborns with diagnosis of Vein of Galen aneurysmal malformation (choroidal variety) through doppler echocardiography. Two reference groups were formed: 1) 70 supposedly healthy children; 2) 73 children with Vein of Galen malformation with a nature different to the studied choroidal variety. Processing of the information included elements of inferential statistics and tools from medicine based in evidences. Results: The presence of neonatal heart failure, electrocardiographic signs of myocardial ischemia and detection of transcranial continuous murmur were significantly different in the study group in relation with the reference group (p= 0,000001), with predominance in the number of patients of the study group in all the variables. The previous results combined with different ultrasound findings as the anomalous dilation of the vein, the excess of afferent vasculature, the reduction of encephalic circulation indexes and the increase of the supraaortic vascular diameters identified in a precise way the vein of Galen aneurysmal malformation. The assessment of the relative risk reaffirmed the information on the exposed findings. Conclusions: Doppler echography, due to its clinical importance and its links with other diagnostic elements, is mandatory in the detection of the vein of Galen aneurysmal malformation(AU)

ABSTRACT

RESUMEN Objetivo: Evaluar los valores de referencia de la dinámica circulatoria arterial ocular de los pacientes con hipertensión arterial esencial. Métodos: Se realizó un estudio descriptivo y transversal en 105 pacientes hipertensos y en un grupo de 33 sujetos no hipertensos, con edades comprendidas entre 18 y 60 años, sin antecedentes de padecer diabetes mellitus ni enfermedades oculares como glaucoma, o haber recibido tratamiento quirúrgico por catarata, hipertensión ocular u otras. A todos se les realizó la toma de la presión arterial sistémica, el examen clínico oftalmológico y el ultrasonido Doppler a color de carótida y de los vasos orbitarios. Resultados: Se encontró un predominio de mujeres de piel blanca, entre la cuarta y quinta década de la vida. Existió un incremento del pico de velocidad sistólica, la velocidad final diastólica y el índice de resistencia en la arteria oftálmica, que fue desde un rango normal en el grupo de los no hipertensos a valores promedios elevados en el grupo de hipertensos, los cuales fueron más altos en los casos descontrolados. No se encontraron modificaciones en el análisis de estos parámetros en las arterias centrales de la retina ni en las ciliares posteriores cortas. Conclusiones: En la casuística estudiada, el incremento del pico de la velocidad sistólica en la arteria oftálmica pudiera estar relacionado con áreas de obstrucción vascular localizadas o con vasoespasmo. Se encontró una asociación entre el descontrol de la presión arterial y los valores elevados del índice de resistencia en la arteria oftálmica(AU)


ABSTRACT Objective: Evaluate the reference values for ocular arterial circulation dynamics in patients with essential arterial hypertension. Methods: A descriptive cross-sectional study was conducted of 105 hypertensive patients and a group of 33 non-hypertensive subjects aged 18-60 years with no antecedents of diabetes mellitus or ocular conditions such as glaucoma or having undergone cataract surgery, ocular hypertension or others. All the patients underwent systemic arterial pressure measurement, clinical ophthalmological examination and color Doppler carotid and orbital ultrasonography. Results: A predominance was observed of the female sex, white skin color and age between the fourth and fifth decades of life. There was an increase in peak systolic velocity, end diastolic velocity and the resistive index in the ophthalmic artery, which ranged from normal in the non-hypertensive group to high average levels in the hypertensive group, higher in uncontrolled cases. Analysis of these parameters did not find any change in central retinal or short posterior ciliary arteries. Conclusions: In the cases studied, the peak systolic velocity increase in the ophthalmic artery could be related to localized vascular obstruction areas or vasospasm. An association was found between uncontrolled arterial pressure and high resistive index values in the ophthalmic artery(AU)

ABSTRACT

SUMMARY OBJECTIVES To prospectively investigate the alterations and normal ranges of ureteral jet dynamics after double-J-stent (DJS) removal in patients who underwent renal transplantation (RTx). METHODS Patients who underwent RTx were prospectively evaluated between November 2017 and June 2018. After RTx, Doppler ultrasonography (D-US) was performed on all patients after DJS removal. Renal artery resistive index (RA-Ri), renal pelvis anterior-posterior diameter (RP-APD), pelvicalyceal system dilation (PCSD), and ureteral jet flow dynamics (maximum and average velocity; JETmax and JETave) were measured by D-US. Also, patients' demographics, estimated glomerular filtration rate (eGFR) levels, and acute rejection were investigated in the study. Patients were assessed two different times by D-US, about 6 and 12 weeks after DJS removal, and the two different measurements were compared with the Wilcoxon test and Chi-square test. RESULTS A total of 25 patients were evaluated in the study. Nonobstructive PCSD rate (12% vs 8%), JETave (18.8 vs 12.9 cm/sec), and JETmax (29.2 vs 20 cm/sec) levels were significantly decreased (p values are 0.01, 0.010 and 0.014, respectively). In addition, monophasic and square pattern rates were significantly observed to increase over time (p=0.035); however, ureteral jet patterns were correlated between the two different D-US measurements (R=0.225, p=0.032). CONCLUSION After RTx, dilation rate and ureteral jet flow velocities were significantly decreased, and monophasic and square JETpattern rates were significantly increased over time. Ureteral jet dynamics can provide useful information about the follow-up of peristaltic activity in the pelvic-ureteric system.


RESUMO OBJETIVOS Investigar prospectivamente as alterações e as variações normais da dinâmica do jato ureteral após a remoção do J-stent duplo (DJS) em pacientes submetidos a transplante renal (RTx). MÉTODOS Pacientes submetidos a RTx foram avaliados prospectivamente entre novembro de 2017 e junho de 2018. Após o RTx, o D-US foi realizado em todos os pacientes após a remoção do DJS. Índice de resistência da artéria renal (RA-Ri), diâmetro ântero-posterior da pelve renal (AP-DPR), dilatação do sistema pelvicaliceal (PCSD) e dinâmica do jato ureteral (velocidade máxima e média; JETmax e JETave) foram medidos por D-US. Além disso, a demografia dos pacientes, os níveis estimados de taxa de filtração glomerular (eGFR) e a rejeição aguda foram investigados no estudo. Os pacientes foram avaliados em dois momentos diferentes pelo D-US, cerca de 6 e 12 semanas após a remoção do DJS, e as duas medidas diferentes foram comparadas com o teste de Wilcoxon e o teste do qui-quadrado. RESULTADOS Um total de 25 pacientes foi avaliado no estudo. Taxa de PCSD não obstrutiva (12% vs. 8%), JETave (18,8 vs. 12,9 cm/seg) e JETmax (29,2 vs. 20 cm/seg), os níveis foram significativamente diminuídos (valores de p são 0,01, 0,010 e 0,014, respectivamente). Além disso, as taxas de padrão monofásico e quadrado foram significativamente observadas para aumentar ao longo do tempo (p=0,035); no entanto, padrões de jato ureteral foram correlacionados entre as duas diferentes medidas D-US (R=0,225, p=0,032). CONCLUSÃO Após o RTx, a velocidade de dilatação e as velocidades de fluxo do jato ureteral foram significativamente diminuídas e as taxas de JET padrão monofásico e quadrado foram significativamente aumentadas ao longo do tempo. A dinâmica do jato ureteral pode fornecer informações úteis sobre o acompanhamento da atividade peristáltica no sistema pélvico-ureteral.

ABSTRACT

ABSTRACT Purpose: To evaluate the role of contrast-enhanced ultrasound (CEUS) in differentiating bland thrombus from tumor thrombus of the inferior vena cava (IVC) in patients with renal cell carcinoma (RCC). Materials and Methods: We retrospectively investigated 30 consecutive patients who underwent robot-assisted radical nephrectomy with IVC thrombectomy and had pathologically confirmed RCC. All patients underwent US and CEUS examination. Two off-line readers observed and recorded thrombus imaging information and enhancement patterns. Sensitivity, specificity, accuracy, positive predictive value and negative predictive value for bland thrombus were assessed. Results: Of the 30 patients, no adverse events occurred during administration of the contrast agent. Early enhancement of the mass within the IVC lumen on CEUS was an indicator of tumor thrombus. Bland thrombus showed no intraluminal flow on CEUS. There were eight (26.7%) patients with bland thrombus, including three level II, two level III, and three level IV. There were three cases with cephalic bland thrombus and five cases with caudal bland thrombus. Three caudal bland thrombi extended to the iliac vein and underwent surgical IVC interruption. Based on no intraluminal flow, for bland thrombus, CEUS had 87.5% sensitivity, 100% specificity, 96.7% accuracy, 100% positive predictive value and 95.6% negative predictive value. Conclusion: Our study demonstrates the potential of CEUS in the differentiation of bland and tumor thrombus of the IVC in patients with RCC. Since CEUS is an effective, inexpensive, and non-invasive method, it could be a reliable tool in the evaluation of IVC thrombus in patients with RCC.

ABSTRACT

ABSTRACT Varicose gastrointestinal bleeding is one of the major causes of morbidity and mortality in patients with chronic liver disease. Endoscopic treatment is the first therapeutic line for these patients, however, for those whom this therapeutic modality fail, a broad knowledge of alternative treatment options may improve the prognosis. We describe a case of a patient who were successfully embolized from gastroesophageal varices via transsplenic access.


RESUMO O sangramento gastrointestinal varicoso está entre as maiores causas de morbimortalidade nos paciente com doença hepática crônica. O tratamento endoscópico é a primeira linha terapêutica neste pacientes, porém naqueles que apresentam falha nesta modalidade terapêutica, o amplo conhecimento de opções alternativas de tratamento pode melhorar o prognóstico. Descrevemos um caso de paciente submetido à embolização com sucesso de varizes gastresofágicas por acesso transesplênico.

ABSTRACT

Cuando un nódulo tiroideo muestra características ecográficas sospechosas de malignidad (informada con clasificación T-RADS) casi no se discute que debe completarse el diagnóstico con una punción aspirativa con aguja fina (PAAF) (informada con sistema Bethesda). Pero cuando la ecografía sólo muestra características consideradas de benignidad, la indicación de PAAF es cuestionable y debe ser justificada. ¿Podrá la clasificación T-RADS determinar eficientemente cuáles nódulos tiroideos requieren una PAAF y cuáles no? Esta decisión está vinculada a determinar si un paciente deberá ser sometido o no a una cirugía tiroidea. Objetivo: Analizar la capacidad de la clasificación T-RADS, con y sin el agregado de sistema Bethesda para optimizar el diagnóstico de patología tiroidea. Material y métodos: se incluyeron 139 nódulos que requirieron cirugía, previamente evaluados con ecografía y con PAAF. Fueron realizadas por un mismo operador las ecografías (SMB), las punciones (OBM) y las cirugías (JLN). Se homogeneizaron las definiciones: T-RADS II-III-IVa y Bethesda II-III: Baja sospecha de malignidad; T-RADS IVb-V-VI y Bethesda IV-V-VI: Alta sospecha de malignidad. Conslusiones: se comprobó que cuando las características ecográficas de un nódulo tienen baja sospecha de malignidad (T-RADS II-III-IVa), indicar una PAAF no aporta al diagnóstico en forma estadísticamente significativa. Cuando la ecografía indica alta sospecha de malignidad (T-RADS IVb-V-VI), la realización de una PAAF incrementa significativamente la certidumbre del diagnóstico (AU)


When a thyroid nodule shows ultrasonographic characteristics of malignancy suspicion (informed with T-RADS classification), almost nobody discusses to complete diagnosis with a fine needle aspiration biopsy (FNAB) (informed with Bethesda system). But when ultrasonography only shows characteristics compatible with benignity, a FNAB indication is questionable and that must be justified. Could T-RADS classification efficiently identify which nodule requires a FNAB and which does not? That decision will linked to which patients should be undergo a thyroid surgery. Objective: to analyze T-RADS capability with and without Bethesda system to optimize the diagnosis of thyroid pathology. Material and methods: a total of 139 nodules which required surgery were included. They were previously evaluated with ultrasonography and FNAB. A same operator classified the T-RADS (SMB), the Bethesda system (OMB) and performed the surgeries (JLN). For this work, definitions were homogenized as follows: T-RADS II-III-IVa and Bethesda II-III: Low suspicion of malignancy; T-RADS IVb-V-VI and Bethesda IV-V-VI: High suspicion of malignancy. Conclusions: the evidence suggested that when a thyroid nodule shows low suspicion of malignancy by ultrasonography (T-RADS II-III-IVa), the indication of a FNAB did not add statistically significant diagnostic benefit. When a thyroid nodule shows high suspicion of malignancy (T-RADS IVb-V-VI), a FNAB added significant diagnostic accuracy (AU)

ABSTRACT

ABSTRACT Objective Hürthle cell carcinomas (HCCs) of the thyroid have been recently reclassified as a separate entity due to their distinct clinical and molecular profiles. Few studies have assessed the ability of preoperative characteristics in differentiating HCCs from Hürthle cell adenomas (HCAs) due to the low prevalence of both lesions. This study aimed to compare the preoperative features of HCCs and HCAs and evaluate the diagnostic performance of ultrasound in distinguishing between both. Subjetcs and methods Retrospective study including 101 patients (52 HCCs and 49 HCAs) who underwent thyroid surgery from 2000 to 2016. Clinical, ultrasonographic, and histological data were reviewed. Diagnostic performance of suspicious sonographic features was analyzed in 51 cases (24 HCCs and 27 HCAs). Results Hürthle cell neoplasms were predominant in females. Subjects ≥ 55 years represented 58% of the cases of HCCs and 53% of those of HCAs. Carcinomas were significantly larger (p < 0.001), and a tumor size ≥ 4 cm significantly increased the risk of malignancy (odds ratio 3.67). Other clinical, cytologic, and sonographic data were similar between HCCs and HCAs. Among the HCCs, the lesions were purely solid in 54.2%, hypoechoic in 37.5%, and had coarse calcifications in 12.5%, microcalcifications in 8.3%, irregular contours in 4.2%, and a taller-than-wide shape in 16.7%. Predominantly/exclusive intranodular vascularization was observed in 52.6%. Overall, 58% of the HCCs were classified as TI-RADS 4 or 5 compared with 48% of the HCAs. TI-RADS 4 or 5 had a specificity of only 51.8% and a positive likelihood ratio of 1.21. Conclusions Apart from the lesion size, no other preoperative feature adequately distinguished HCCs from HCAs. Sonographic characteristics raising suspicion for malignancy, which are mostly present in papillary carcinomas, were infrequent in HCCs. New tools must be developed to improve preoperative diagnosis and deferral of surgery in cases of adenomas.

ABSTRACT

A hidradenite supurativa (HS) é uma doença inflamatória crônica da pele caracterizada por apresentar nodulações subcutâneas, dolorosas e com sinais flogísticos, inicialmente enrijecidas e que evoluem para consistência amolecida. Ocorre em 1 a 4% da população mundial. A sua etiologia ainda é pouco conhecida, sugere-se que aconteça devido à oclusão do ducto apócrino dos folículos pilosos por fatores precipitantes como fricção de tecido adiposo, higiene precária, entre outras. Seu diagnóstico é eminentemente clínico, pela identificação de lesões típicas recorrentes em forma de nodularidades, abcessos, tratos fistulosos ou cicatrizes. Não há testes patognomônicos. Sua evolução é variável e de difícil manejo, o qual pode ser feito com terapia tópica, sistêmica ou por exérese cirúrgica. Este trabalho revisa a avaliação por imagem da hidroadenite supurativa e demonstra imagens de um caso avaliado por ressonância magnética. A avaliação por exames de imagem, apesar de pouco específica para firmar diagnóstico, é muito útil na determinação da extensão da doença, assim como na exclusão de diagnósticos diferenciais, destacando-se o papel da ressonância magnética na avaliação das lesões anogenitais, com potencial de reduzir recorrências.


Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by painful deep-seated skin nodules with phlogistic signs, which are initially hard and progress to have a soft consistency. It occurs in 1­4% of the world population. Etiology of HS is still poorly understood and is suggested to occur due to occlusion of the apocrine duct of the hair follicles by triggering factors such as friction of the adipose tissue and poor hygiene, among others. Diagnosis is eminently clinical, through the identification of typical recurrent lesions that include nodules, abscesses, sinus tracts, or scars. There are no pathognomonic tests used to confirm its presence. Progression is variable and difficult to manage, which can be done with topical or systemic therapy or surgical excision. This work reviews the imaging assessment of HS and shows images of a case assessed by magnetic resonance imaging. Imaging assessment, although not specific enough for a diagnosis, is useful to determine the extent of the disease and to exclude differential diagnoses. Moreover, magnetic resonance imaging has an important role in the assessment of anogenital lesions and a potential to reduce recurrences.

ABSTRACT

Introducción: La malformación aneurismática de la vena de Galeno es una infrecuente variedad de fístula arteriovenosa cerebral de origen embriológico. Se localiza en la línea media de la fisura coroidal y tiene morfología de amplio espectro. Objetivo: Exponer información actualizada acerca del tema. Método: La información se obtuvo de la búsqueda automatizada realizada fundamentalmente en bases de datos MEDLINE, Current Contents y Scielo. Resultados: La malformación aneurismática de la vena Galeno se manifiesta con síntomas y signos derivados de la insuficiencia cardiaca severa refractaria al tratamiento médico y del daño neurológico que provoca. La entidad implica morbilidad grave y mortalidad en el periodo neonatal. La angiorresonancia es la técnica de referencia, pero la ecografía doppler es buen método de valoración. El tratamiento de elección es la embolización endovascular. Consideraciones finales: Debe existir índice elevado de sospecha para no fracasar en el diagnóstico precoz de la enfermedad. Es importante definir la anatomía de la lesión, por las implicaciones clínicas, terapéuticas y pronósticas que ello acarrea. El tratamiento exitoso sigue siendo un reto terapéutico complejo(AU)


Introduction: Vein of Galen aneurysm is a rare and congenital cerebral arteriovenous abnormality with reported incidence of 1:25 000 live births. It represents the 30 percent of the vascular congenital cerebral malformations that harm the pediatric population. Objective: To show updated information about the topic. Method: The information was obtained from the automated search mostly done in MEDLINE, CurrentContents and Scielo databases. Development: Vein of Galen malformation presents with symptoms and signs derived from the severe refractary heart failure to medical treatment and the neurologic damage it causes. That entity implies severe morbidity and mortality on the neonatal period. Angioresonance is the reference technique, but the Doppler ecography is a good valuation method. The election treatment is the endovascular embolization. Final considerations: There must be an elevated rate of suspect to do not fail on the early diagnostic of the disease. It is important to define the lesion's anatomy, because of the clinic, therapeutic and prognostic implications this represent. The successful treatment is still a complex therapeutic challenge(AU)

ABSTRACT

Celiac artery compression syndrome, also referred to as median arcuate ligament syndrome, celiac axis syndrome or Dunbar syndrome is a rare disorder consequent to extrinsic compression of the celiac trunk by the median arcuate ligament. Doppler ultrasound, multi-slice computed tomography angiography, magnetic resonance angiography, or invasive selective angiography can identify stenosis of the initial segment of the celiac artery and confirm diagnosis. Treatment options include open surgical or videolaparoscopic section of the median arcuate ligament and the fibers of the celiac plexus, or percutaneous transluminal angioplasty via an endovascular approach. We report herein an interesting case of a 38-year-old woman diagnosed with this rare condition and successfully treated with the surgical strategy


A síndrome da compressão da artéria celíaca, também denominada síndrome do ligamento arqueado mediano, síndrome do eixo celíaco ou síndrome de Dunbar, é uma doença rara causada pela compressão extrínseca do tronco celíaco pelo ligamento arqueado mediano. Ultrassonografia Doppler, angiotomografia computadorizada, angiorressonância magnética ou angiografia seletiva invasiva conseguem identificar a estenose do segmento inicial da artéria celíaca e confirmar o diagnóstico. As opções de tratamento incluem secção videolaparoscópica ou laparotômica (a céu aberto) do ligamento arqueado mediano e das fibras do plexo celíaco, assim como angioplastia transluminal percutânea. Relatamos o interessante caso de uma mulher de 38 anos de idade diagnosticada com essa rara condição e adequadamente tratada pela estratégia cirúrgica

ABSTRACT

Mostra-se relevante a elucidação da influência da densidade de energia endovenosa linear (linear endovenous energy density, LEED) média no sucesso do tratamento da insuficiência venosa crônica por termoablação endovenosa a laser visando diminuir a morbidade desse método. Objetivos Avaliar a influência da LEED média na prevalência de fechamento das safenas após 30 dias do procedimento. Métodos Foram analisados 153 membros inferiores de 118 pacientes de um hospital referência, submetidos a termoablação com laser endovenoso 1470 nm sob anestesia local para o tratamento de insuficiência venosa crônica. Foi calculada a LEED média dos pacientes tratados para determinar se foi necessária uma energia maior que a média para o sucesso do tratamento. Resultados Dos 153 membros inferiores submetidos ao tratamento, houve diferença significativa (p = 0,021) no fechamento da junção safeno-femoral relacionada à LEED média utilizada acima do joelho. Por outro lado, no segmento de coxa não houve diferença significativa. Conclusões A LEED acima da média de 70,57 J/cm apresentou um índice maior de fechamento na junção safeno-femoral. Porém, no segmento de coxa, a densidade não influenciou o resultado, demonstrando que uma energia mais alta do que 70,57 J/cm tende a não ser necessária para o tratamento desse segmento


It is relevant to elucidate the influence that mean linear endovenous energy density (LEED) has on the success of endovenous laser ablation treatment for chronic venous insufficiency, in order to reduce the method's adverse effects. Objectives To evaluate the influence of mean LEED on the prevalence of saphenous closure 30 days after the laser ablation procedure. Methods 153 lower limbs from 118 patients seen at a tertiary hospital and treated for chronic venous insufficiency with endovenous 1470 nm laser ablation under local anesthesia were evaluated. The mean LEED used to treat patients was calculated to determine whether greater than average LEED was required for treatment success. Results A significant difference (p = 0.021) in saphenofemoral junction closure was associated with mean LEED used above the knee. Conversely, there was no significant difference in the thigh segment. Conclusions Linear intravenous energy density greater than the mean of 70.57 J/cm was associated with a higher rate of closure at the saphenofemoral junction. However, density did not have an influence on the result for the thigh segment, showing that an energy density exceeding 70.57 J/cm tends not to be required for treatment of this segment

ABSTRACT

Giant cell arteritis is the most common vasculitis in patients aged over 50 years. We report an 89-year-old woman with significant weight loss and persistent frontal-occipital headaches lasting two months. The neurological examination at admission identified a decrease in visual acuity of the left eye, paralysis of the third cranial nerve of the right eye and alterations of body motility without objective signs of damage of the motor or sensitive pathways. Magnetic resonance imaging showed changes of the temporal artery wall and in both vertebral arteries, as well as bilateral cerebellar and occipital ischemic lesions. The Doppler ultrasound of the temporal arteries was compatible with Giant cell arteritis. Treatment with steroids was started. While receiving oral prednisone, the patient suffered new infarcts of the posterior territory, documented with a CAT scan.

ABSTRACT

Pseudoaneurysms of gluteal arteries are rare, especially involving the inferior gluteal artery. They are mainly associated with penetrating trauma, infections, or pelvic fractures. A minority of cases are caused by blunt traumas, with only six cases reported in English. We present a case of pseudoaneurysm of the right inferior gluteal artery after a bicycle fall, presenting with a large hematoma in the gluteal region, observed during clinical examination, and significantly reduced hemoglobin. CT angiography revealed a large hematoma, with contrast extravasation and pseudoaneurysm formation. Angiography revealed that the origin of the lesion was in the right inferior gluteal artery. This artery was embolized with coils. After the procedure, the patient was referred to an intensive care unit, from where he was later transferred to a different hospital, with bleeding controlled. Endovascular treatment of these cases is a safe, fast and an effective option


Pseudoaneurismas de artérias glúteas são raros, especialmente os que envolvem a artéria glútea inferior. Eles estão associados principalmente a traumas penetrantes, infecções ou fraturas de pelve. Em uma minoria de casos, são causados por traumas fechados, havendo somente seis casos relatados na literatura. Apresenta-se aqui um caso de pseudoaneurisma da artéria glútea inferior direita após queda de bicicleta, evoluindo com grande hematoma na região glútea ao exame clínico e queda hematimétrica significativa. A angiotomografia revelou um grande hematoma na região glútea, com extravasamento de contraste e formação de pseudoaneurisma no local. A angiografia revelou que a origem da lesão era na artéria glútea inferior direita. Foi realizada embolização dessa artéria com molas. Após esse procedimento, o paciente foi encaminhado para a unidade de terapia intensiva, de onde foi posteriormente transferido para outro hospital, com o sangramento controlado. Para esses casos, o tratamento endovascular é uma opção segura, rápida e efetiva

ABSTRACT

A síndrome de quebra-nozes é caracterizada por um grupo de manifestações clínicas que ocorrem por conta da compressão da veia renal esquerda. Seus principais sintomas são macro e micro-hematúria, proteinúria e dor no flanco. O diagnóstico é geralmente realizado após a exclusão de outras causas mais comuns, por conta da ausência de critérios clínicos para diagnóstico. Sua confirmação é feita por exames de imagem, com uso da ultrassonografia Doppler e tomografia computadorizada. O tratamento pode variar com as características do paciente e com a gravidade dos sintomas, e inclui o tratamento conservador, a cirurgia aberta e a cirurgia endovascular. Atualmente, a cirurgia aberta continua sendo a linha de frente, mas abordagens menos invasivas vêm ganhando cada vez mais espaço


The nutcracker syndrome is characterized by a group of clinical manifestations caused by compression of the Left Renal Vein. The main symptoms are: macro and micro hematuria, proteinuria, and flank pain. Diagnosis is usually made after excluding other causes, because there are no clinical criteria for diagnosis. Confirmation is by Doppler ultrasonography or computed tomography. Treatment can vary, depending on patient characteristics and the severity of the symptoms, while conservative treatment, open surgery, and endovascular surgery may be employed. Currently, open surgery is still the first-line treatment, but some less invasive approaches are gaining acceptance
