ABSTRACT

Abstract Introduction: In-line positioning of an ultrasound image provides higher success rates and less time to completion for radial arterial cannulation. But preferable size and distance of ultrasound display has not been previously discussed. Objective: To assess the ideal visual distance and display size when using a smart phone or tablet as the ultrasound image display. Methods: Four smart phones or tablets were used as ultrasound displays in six different configurations in a simulated radial artery puncture. In a questionnaire, 116 anaesthesiologists working in Ibaraki Prefecture, Japan, were asked which of the six configurations was preferable for radial artery cannulation. Results: Sixty anaesthesiologists answered the questionnaire. About half (53%) preferred the smaller display (4- or 5.5-inch) fixed at a distance of 30 to 40 cm, and most of the rest (44%) preferred the larger display (7.9- or 9.7-inch) placed posterior to the probe with a visual distance of 45 to 60 cm. Conclusions: Among the anaesthesiologists, the preferable size and visual distance for ultrasound-guided radial artery cannulation varied using a smart phone or tablet for in-line display.


Resumen Introducción: El posicionamiento en línea con una imagen ecográfica permite mayores tasas de éxito y reduce el tiempo para realizar la canalización de la arteria radial. Sin embargo, no se ha hablado sobre cuál es el tamaño y la distancia preferibles para la imagen en pantalla. Objetivo: Evaluar la distancia visual y el tamaño de la imagen en pantalla cuando se utiliza un teléfono inteligente o una tableta para visualizar la imagen ecográfica. Métodos: Se utilizaron cuatro teléfonos inteligentes o tabletas como pantalla para visualizar las imágenes ecográficas en seis configuraciones distintas, en una simulación de la canalización de la arteria radial. Mediante un cuestionario se preguntó a 116 anestesiólogos que trabajan para la Prefectura de Ibaraki, Japón, cuál de las seis configuraciones era preferible para la canalización de la arteria radial. Resultados: Sesenta anestesiólogos respondieron el cuestionario. Aproximadamente la mitad (53%) prefirieron la imagen más pequeña (4 o 5,5 pulgadas), fija a una distancia de 30 a 40 cm, y la mayoría de los otros (44%) prefirieron la imagen más grande (7,9- o 9,7 pulgadas), colocada en la parte posterior al transductor, con una distancia visual de 45 a 60 cm. Conclusiones: Entre los anestesiólogos, el tamaño preferido y la distancia visual para la canalización de la arteria radial guiada por ecografía, varió utilizando un teléfono inteligente o una tableta para su visualización en línea.

ABSTRACT

Los traumas vasculares periféricos poseen una frecuencia elevada en relación con las lesiones vasculares y conllevan a una incapacidad significativa a pacientes relativamente jóvenes. La identificación oportuna y el manejo inicial adecuado de este tipo de lesión son muy importantes para su posterior evolución. Este artículo tuvo como objetivo exponer la importancia del tratamiento oportuno del trauma vascular en dos pacientes llegados el mismo día al servicio de urgencias del Hospital Militar Central "Dr. Luis Díaz Soto". Se presenta como primer caso a un paciente masculino de 44 años de edad, con antecedentes de salud aparente. Sufrió una herida de aproximadamente 12 cm en el brazo izquierdo, que se acompañó de sangramiento e hipotensión arterial. Se le colocó injerto protésico y se le realizó anastomosis término-terminal en la arteria humeral porque presentaba sección completa de esta; su evolución fue favorable. El segundo caso se trata de un paciente masculino de 60 años de edad, con antecedentes de salud aparente. Sufrió un trauma en el antebrazo izquierdo que le provocó una herida de alrededor de 8 cm, con sangramiento, palidez y frialdad del tercio distal del antebrazo, cianosis reversible de la mano, impotencia funcional, ausencia de pulso radial e hipotensión arterial. Se le realizó anastomosis término-terminal de arteria radial porque presentaba sección completa de esta y su evolución resultó favorable. El tratamiento oportuno y acertado del trauma vascular evitó la pérdida de la vida de los pacientes, disminuyó la presencia de complicaciones, aseguró una evolución rápida y redujo incapacidades en estos(AU)


Peripheral vascular traumas have a high frequency in relation to vascular lesions, and lead to significant disability in relatively young patients. Timely identification and adequate initial management of this type of lesion are very important for its subsequent evolution. This article aimed to show the importance of timely treatment of vascular trauma in two patients who arrived on the same day at the emergency service of Dr. Luis Díaz Soto Central Military Hospital. The first case presented corresponds to a 44-year-old male patient apparently without previous heath conditions. He had a wound of approximately twelve centimeters on the left arm, which was accompanied by bleeding and arterial hypotension. The patient was placed a prosthetic graft and performed an end-to-end anastomosis in the brachial artery because it was completely sectioned. The patient's evolution was favorable. The second case corresponds to a 60-year-old male patient with an apparent health history. He suffered a trauma to his left forearm that caused a wound of about 8 cm, with bleeding, paleness and coldness of the distal third of the forearm, reversible cyanosis of the hand, functional impotence, absence of radial pulse and arterial hypotension. End-to-end anastomosis of the radial artery was performed because the patient presented complete section of the artery and his evolution was favorable. Timely and correct treatment of vascular trauma prevented the loss of life in both patients, reduced the presence of complications, ensured a rapid evolution, and reduced their disabilities(AU)

ABSTRACT

In order to obtain the three-dimensional pulse information and blood pressure waveform needed in the study, a radial artery simulation platform with programmable controlled injection pump as the core was constructed by using the circulation theory of human cardiovascular system and pulse wave formation mechanism. Gaussian function model was selected to synthesize multi-type pulse wave to program and drive the platform. The three-dimensional pulse information and blood pressure waveform of the simulated radial artery were collected by binocular visual pulse detection system and pressure transmitter respectively, and the platform stability and repeatability were tested by Pearson correlation. The experimental results show that the radial artery simulation platform is stable, reliable and repeatable, and can generate multiple types of three-dimensional pulse information and blood pressure waveform at the simulated radial artery. The platform is simple in structure, low in cost, and produces many types of pulsating flow. It provides an experimental research platform for revealing the relationship between the three-dimensional pulse information of radial artery and the change of pressure inside the vessel, as well as the prediction of blood pressure waveform from the three-dimensional pulse information.

ABSTRACT

Abstract Background: One-catheter strategy, based in multipurpose catheters, allows exploring both coronary arteries with a single catheter. This strategy could simplify coronary catheterization and reduce the volume of contrast administration, by reducing radial spasm. To date, observational studies showed greater benefits regarding contrast consumption and catheterization performance than controlled trials. The aim of this work is to perform the first systematic review and meta-analysis of randomized clinical trials (RCT) to adequately quantify the benefits of one-catheter strategy, with multipurpose catheters, over conventional two-catheter strategy on contrast consumption, and catheterization performance. Methods: A search in PubMed, CINALH, and CENTRAL databases was conducted to identify randomized trials comparing one-catheter and two-catheter strategies. The primary outcome was volume of iodinated contrast administrated. Secondary endpoints, evaluating coronary catheterization performance included: arterial spasm, fluoroscopy time, and procedural time. Results: Five RCT were included for the final analysis, with a total of 1599 patients (802 patients with one-catheter strategy and 797 patients with two-catheter strategy). One-catheter strategy required less administration of radiological contrast (difference in means [DiM] [95% confidence interval (CI)]; −3.831 mL [−6.165 mL to −1.496 mL], p = 0.001) as compared to two-catheter strategy. Furthermore, less radial spasm (odds ratio [95% CI], 0.484 [0.363 to 0.644], p < 0.001) and less procedural time (DiM [95% CI], −72.471 s [−99.694 s to −45.249 s], p < 0.001) were observed in one-catheter strategy. No differences on fluoroscopy time were observed. Conclusions: One-catheter strategy induces a minimal reduction on radiological contrast administration but improves coronary catheterization performance by reducing arterial spasm and procedural time as compared to conventional two-catheter strategy.


Resumen Antecedentes: La estrategia de catéter único permite explorar ambas coronarias con un solo catéter. Nuestro objetivo es realizar la primera revisión sistemática y meta-análisis de ensayos clínicos aleatorizados para cuantificar adecuadamente los beneficios de la estrategia de catéter único, con catéteres multipropósito, sobre la estrategia convencional de dos catéteres. Métodos: Se realizó una búsqueda en PubMed, CINALH y CENTRAL, identificando ensayos aleatorizados que compararan estrategias de un catéter y dos catéteres. El resultado primario fue volumen de contraste administrado. Los secundarios, que evaluaron el rendimiento del cateterismo, incluyeron: espasmo radial, tiempo de fluoroscopia y de procedimiento. Resultados: Se incluyeron cinco ensayos, totalizando 1,599 pacientes (802 con estrategia de un catéter y 797 con estrategia de dos catéteres). La estrategia de catéter único requirió menos contraste (diferencia-de-medias; −3.831 mL [−6.165 mL a −1.496 mL], p = 0.001), presentando menos espasmo radial (odds ratio, 0.484 [0.363 a 0.644], p < 0.001) y menos tiempo de procedimiento (diferencia-de-medias; −72.471 s [−99.694 s a −45.249 s], p < 0.001). No hubo diferencias en el tiempo de fluoroscopia. Conclusiones: La estrategia de catéter único induce una reducción mínima en la administración de contraste, pero mejora el rendimiento del cateterismo al reducir el espasmo radial y el tiempo de procedimiento en comparación con la estrategia convencional.

ABSTRACT

Resumen Objetivo: describir la experiencia de un servicio en angiografía coronaria en cuanto al abordaje radial distal izquierdo a través de la tabaquera anatómica. Material y método: de abril a agosto de 2018 se asignaron 40 pacientes a angiografía coronaria por vía radial izquierda distal a través de la tabaquera anatómica. Se hizo un análisis de tipo descriptivo de las principales variables cuantitativas asociadas al procedimiento (frecuencia de acceso fallido, procedimiento fallido, tiempo de procedimiento, tiempo de fluoroscopia, nivel de dolor en el paciente, sensación de comodidad para el paciente y para el operador, cantidad de medio de contraste empleado y algunas variables demográficas). Se incluyeron pacientes mayores de 18 años con indicación de arteriografía coronaria para estudio diagnóstico y con pulso palpable en la zona de la tabaquera anatómica. Resultados y conclusión: la cantidad de medio de contraste en promedio empleada fue de 49 ml (SD ± 13), el tiempo promedio de procedimiento fue de 11,3 minutos (SD ± 4.3) y el tiempo de fluoroscopia promedio fue de 3,3 minutos (SD ± 2.8). La mediana para el nivel de dolor en los pacientes fue de 4, la mediana para la comodidad del operador fue de 10 y la mediana para la comodidad en el paciente fue de 10. Se concluye así que el acceso radial distal izquierdo es una alternativa técnicamente factible, ofrece comodidad para el paciente y el operador, y arroja bajas tasas de falla y complicaciones en pacientes seleccionados.


Abstract Objective: To present the experience of one Department in coronary angiography as regards the left distal radius approach through the anatomical snuff box. Material and Method: A total of 40 patients were subjected to coronary angiography through the anatomical snuff box, from April to August 2018. A descriptive analysis was performed on the quantitative variables associated with the procedure (frequency of failed access, failed procedure, procedure time, fluoroscope time, patient pain level, feeling of comfort for the patient and for the operator, amount of contrast used, and some demographic variables). The study included patients over 18 years-old with an indication for coronary angiography for a diagnostic study, and with a palpable pulse in the anatomic snuff box area. Results and conclusion: The mean amount of contrast media employed was 49 ml (SD ± 13), the mean procedure time was 11.3 minutes (SD ± 4.3), and the mean fluoroscope time was 3.3 minutes (SD ± 2.8). The median for the pain level in patients was 4, the median for comfort of the operator was 10, and the median for comfort of the patient was also 10. It was able to be concluded that the left distal radial access is a technically feasible alternative. It is comfortable for the patient and the operator, with low failure rates and complications in selected patients.

ABSTRACT

La arteria recurrente radial nace en el extremo proximal de la arteria radial y desde ahí asciende oblicuamente para anastomosarse con la arteria colateral radial, entregando en ese trayecto una serie de ramas para los músculos cercanos. Dicha arteria junto con sus ramas fueron descritas (por su importancia en abordajes quirúrgicos) por Arnold K. Henry como "the radial leash". Actualmente en clínica se utiliza el nombre "leash of Henry" para referirse a una o más ramas musculares de la arteria recurrente radial, sobretodo cuando cuando se encuentran en relación con el ramo profundo del nervio radial, pudiendo llegar a causar compresiones de dicho nervio en algunos casos. Se realizó una descripción de caso de una leash of Henry atípica, encontrada en una muestra cadavérica del laboratorio de anatomía de la Universidad Católica del Maule, de sexo masculino y nacionalidad chilena. La arteria encontrada corresponde a la rama de mayor calibre de la arteria recurrente radial, que se dirige directamente al músculo extensor de los dedos, dibujando un trayecto horizontal y cruzando por anterior al ramo profundo del nervio radial. Esta hallazgo difere a lo descrito por Henry y otros autores más recientes, y por lo tanto aporta información potencialmente útil a la hora de realizar procedimientos quirúrgicos que requieran un abordaje posterior o lateral de la cabeza del radio, como también descompresiones del nervio radial en esta zona.


The radial recurrent artery originates at the proximal end of the radial artery and from there ascends obliquely to anastomosing with the radial collateral artery. It gives off several branches for nearby muscles on its path. This artery along with its branches were described (due to its importance in surgical approaches) by Arnold K. Henry as "the radial leash". Currently, in clinical terms, the name "Leash of Henry" is used to refer to one or more muscular branches of the radial recurrent artery, especially when they are in relation to the deep branch of the radial nerve, and may cause compression of the nerve in some cases. A case description of an atypical Leash of Henry was found, found in a Chilean, male cadaveric sample of the anatomy laboratory, Universidad Católica del Maule. The artery corresponds to the branch of greater caliber of the recurrent radial artery, which goes directly to the extensor digitorum muscle. It draws a horizontal path and crosses the deep branch of the radial nerve anteriorly. This finding differs from what was described by Henry and other more recent authors. Therefore, this is potentially useful information when performing surgical procedures that require a posterior or lateral approach to the radius head, as well as radial nerve decompressions in this area.

ABSTRACT

El arco palmar superficial (APS) resulta de la unión de la arteria ulnar y la rama palmar superficial de la arteria radial. Por su convexidad nacen las arterias digitales comunes. Esta descripción es la única que distintos autores han tomado como válida, por lo que se espera encontrarla durante la disección con mayor frecuencia. Esto no ha sido verificado en nuestra experiencia. Nos proponemos llevar a cabo una revisión de la descripción del APS poniéndolo en contraposición con las disecciones realizadas. Se disecaron y analizaron 61 manos cadavéricas. Estudio del arco palmar superficial: Variante clásica del APS: 23 casos (37,7 %). Variante no clásica del APS: 15 casos (24,6 %). Tipo A: 13 casos (86,7 %). Anastomosis entre arterias ulnar y metacarpiana dorsal del primer espacio. Tipo B: 2 casos (13,3 %). Anastomosis entre arterias ulnar y satélite del nervio mediano. Ausencia del arco: 23 casos (37,7 %) Tipo A: 19 casos (82,6 %). La arteria ulnar es la única estructura en el plano del APS. Tipo B: 3 casos (13 %). La arteria ulnar y la rama palmar superficial de la arteria radial están en el plano del APS sin anastomosarse entre sí. Tipo C: 1 caso (4,4 %). La arteria ulnar y la satélite del nervio mediano están en el plano del APS sin anastomosarse. Estudio de la quinta arteria digital palmar común: La quinta arteria digital palmar común se originó de las distintas variantes en 41 casos (67,2 %). Recomendamos al momento de la disección considerar que: la variante clásica no es la más frecuente de hallar; la ausencia del arco se verifica en el mismo porcentaje que la variante clásica; incluso cuando se comprueba la presencia del APS, el porcentaje de la variante no clásica es contundente; la quinta arteria digital palmar común es una rama colateral constante del APS.


The superficial palmar arch (SPA) is formed by the union of the ulnar artery and the superficial palmar branch of the radial artery. From its convexity four branches emerge, known as the common palmar digital arteries. We propose to carry out a review of the description of the SPA in contrast to the dissections carried out. Sixty-one hands were dissected and studied. Analysis of the SPA: Classic variant of the SPA: 23 cases (37.7 %). Nonclassic variant of the SPA: 15 cases (24.6 %). Type A: 13 cases (86.7 %). Anastomosis between the ulnar artery and the first dorsal metacarpal artery. Type B: 2 cases (13.3 %). Anastomosis between the ulnar artery and the satellite artery of the median nerve. Absence of the arch: 23 cases (37.7 %) Type A: 19 cases (82.6 %). The ulnar artery is the only one present in the plane of the SPA. Type B: 3 cases (13 %). The ulnar artery and the superficial palmar branch of the radial artery are in the plane of the superficial palmar arch, there is no anastomosis between them. Type C: 1 case (4.4 %). The ulnar artery and the satellite artery for the median nerve are in the plane of the SPA, there is no anastomosis between them. Analysis of the fifth common palmar digital artery: The fifth common palmar digital artery originates from the different variants in 41 cases (67.2 %). Based on the results, we recommend at the time of dissecting consider that: The classic variant is not the most frequent to find. The absence of the arch is verified in the same percentage rate as the classic variant. Even when the SPA is present, the percentage rate of the non-classic variant is significant. The fifth common palmar digital artery is a constant collateral branch of the superficial palmar arch.

ABSTRACT

BACKGROUND AND OBJECTIVES: Cigarette smoking has been reported to be associated with arterial stiffness. However, the clinical relevance of smoking cessation on arterial stiffness is debatable. Thus, we evaluated whether smoking cessation is associated with arterial stiffness.METHODS: A total of 1,169 male participants aged 30–64 years with absence of cardiovascular diseases in 2013–2017 were selected from the Cardiovascular and Metabolic Disease Etiology Research Center cohort study. The subjects were classified into the following 5 groups based on self-reporting: non-smokers, former smokers (<1, 1 to <10, and ≥10, years after cessation), and current smokers. Arterial stiffness was assessed using the augmentation index (AIx). The radial artery AIx was obtained from the peripheral artery waveform. The association was explored cross-sectionally.RESULTS: The AIx of former smokers did not differ from that of non-smokers (p=0.089). However, after former smokers were stratified by duration of smoking cessation, we noted a linear trend according to the smoking status (p<0.001). Men who quit smoking <1 year ago showed an elevated AIx (β=3.94, standard error=1.54, p=0.011) as much as ones of current smokers (β=4.39, standard error=0.74, p<0.001), while those who quit more than a decade ago showed an AIx similar to that of non-smokers (β=0.35, standard error=0.82, p=0.670) after controlling covariates.CONCLUSIONS: A dose-response association between smoking cessation and AIx was revealed, which implies the possibility of a reversible effect of smoking cessation on arterial stiffness. Therefore, our findings may motivate current smokers to modify their smoking habits to delay or reverse disease progression.

ABSTRACT

Abstract Introduction: Radial access is the gold standard for ST-elevation myocardial infarction; nevertheless, there is scarce information in Mexico. Objectives: The objectives of this study were to describe the differences in radiation exposure, intervention time, fluoroscopy time, complications and temporal trends, and risk factors among radial and femoral access for coronary procedures. Materials and Methods: A total of 493 patients underwent coronary interventions by femoral or radial access. Sociodemographic and procedural data were recorded. A logistic regression model to determine risk factors for complications was performed. Results: The population included 346 men and 147 women, with a median age of 63 years, 159 underwent radial and 334 femoral approaches. Complications occurred in 18 patients (3.6%), 11 in radial and 7 in femoral access, with a higher trend in the first 5 months (n = 14). Vasospasm was the most common (n = 9) complication. Median fluoroscopy time was 12 min for radial and 9 min for femoral groups, with a total radiation dose of 2282 µGm2 and 2848 µGm2, respectively. Temporal trends showed that complications occurred most frequently during the first 6 months of the study. The main predictors for complications were intervention time and one-vessel disease. Conclusions: Radial access had higher frequency of complications than femoral approach and they were more common during the first 6 months. The main risk factor was intervention time longer than 60 min.


Resumen Introducción: El abordaje radial es el de elección para infarto de miocardio con elevación del segmento ST, sin embargo se desconoce información en México. Objetivos: Describir las diferencias en exposición a radiación, tiempo de intervención, tiempo de fluoroscopía, complicaciones y sus variaciones temporales, además de los factores de riesgo entre el abordaje radial y el femoral para procedimientos coronarios. Método: Se incluyeron 493 pacientes que fueron sometidos a estudio angiográfico o intervenciones coronarias por abordaje radial o femoral. Se recabaron datos sociodemográficos, antecedentes y variables del procedimiento. Se realizó un modelo de regresión logística para determinar los factores asociados a complicaciones. Resultados: Se incluyeron 346 hombres y 147 mujeres, con mediana de edad de 63 años. A 159 se les realizó acceso radial y a 334 femoral. Las complicaciones ocurrieron en 18 pacientes (3.65%): 11 en radial y 7 en femoral, teniendo mayor incidencia en los primeros 5 meses (n = 14) y siendo el vasoespasmo el más común (n = 9). La mediana de tiempo de fluoroscopía fue de 12 minutos para el radial y de 9 minutos para el femoral, con una dosis total de radiación de 2,282 µGm2 y 2,848 µGm2, respectivamente. Las tendencias temporales indicaron que las complicaciones fueron más frecuentes durante los primeros 6 meses. Los principales predictores fueron el tiempo de intervención y la enfermedad de 1 vaso. Conclusiones: La vía de acceso radial tuvo más complicaciones que la femoral. Se observaron más complicaciones en los primeros 6 meses del estudio. El principal predictor de complicaciones fue el tiempo de intervención mayor a 60 minutos.

ABSTRACT

Abstract Objective: To examine the effects of classical technique, electrocautery, and ultrasonic dissection on endothelial integrity, function, and preparation time for harvesting the radial artery (RA) during coronary artery bypass grafting (CABG). Methods: Forty-five patients who underwent isolated CABG and whose RA was suitable for use were studied and divided into three groups: Group 1, classical method (using sharp dissection); Group 2, electrocautery; and Group 3, ultrasonic cautery. Levels of prostacyclin and nitric oxide derivatives were examined biochemically; vascular cell adhesion molecule 1 (VCAM-1) and endothelial nitric oxide synthetase (eNOS) values were assessed using immunohistochemical staining. RA preparation time, RA length/harvesting time ratio, and drainage amounts at the site of RA removal were compared. Results: Differences in RA preparation time (Group 1: 25±6 min, Group 2: 18±3 min, Group 3: 16±3 min, P<0.001) and length/harvesting time ratio (Group 1: 0.76±0.19 cm/min, Group 2: 0.98±0.16 cm/min, Group 3: 1.13±0.09 cm/min, P<0.001) were statistically significant among the groups. Levels of prostacyclin and nitric oxide derivatives were not statistically significant different, VCAM-1 and eNOS expressions were observed to be similar among the groups, and endothelial damage was detected in only one patient per group. Conclusion: Use of ultrasonic cautery during RA preparation considerably reduces the preparation time and postoperative drainage amount. However, the superiority of one method over the others could not be demonstrated when the presence of endothelial damage with both biochemical and histopathological evaluations was considered.

ABSTRACT

Abstract Background: Coronary angiography with two catheters is the traditional strategy for diagnostic coronary procedures. TIG I catheter permits to cannulate both coronary arteries, avoiding exchanging catheters during coronary angiography by transradial access. Objective: The aim of this study is to evaluate the impact of one-catheter strategy, by avoiding catheter exchange, on coronary catheterization performance and economic costs. Methods: Transradial coronary diagnostic procedures conducted from January 2013 to June 2017 were collected. One-catheter strategy (TIG I catheter) and two-catheter strategy (left and right Judkins catheters) were compared. The volume of iodinated contrast administered was the primary endpoint. Secondary endpoints included radial spasm, procedural duration (fluoroscopy time) and exposure to ionizing radiation (dose-area product and air kerma). Direct economic costs were also evaluated. For statistical analyses, two-tailed p-values < 0.05 were considered statistically significant. Results: From a total of 1,953 procedures in 1,829 patients, 252 procedures were assigned to one-catheter strategy and 1,701 procedures to two-catheter strategy. There were no differences in baseline characteristics between the groups. One-catheter strategy required less iodinated contrast [primary endpoint; (60-105)-mL vs. 92 (64-120)-mL; p < 0.001] than the two-catheter strategy. Also, the one-catheter group presented less radial spasm (5.2% vs. 9.3%, p = 0.022) and shorter fluoroscopy time [3.9 (2.2-8.0)-min vs. 4.8 (2.9-8.3)-min, p = 0.001] and saved costs [149 (140-160)-€/procedure vs. 171 (160-183)-€/procedure; p < 0.001]. No differences in dose-area product and air kerma were detected between the groups. Conclusions: One-catheter strategy, with TIG I catheter, improves coronary catheterization performance and reduces economic costs compared to traditional two-catheter strategy in patients referred for coronary angiography.


Resumo Fundamento: A cineangiocoronariografia com dois cateteres é a estratégia tradicional para procedimentos coronarianos de diagnóstico. O cateter TIG I permite canular ambas as artérias coronárias, evitando a troca de cateteres durante a cineangiocoronariografia por acesso transradial. Objetivo: O objetivo deste estudo é avaliar o impacto da estratégia de um cateter, evitando a troca de cateter, no desempenho da coronariografia por cateterismo e nos seus custos econômicos. Métodos: Foram coletados os procedimentos diagnósticos coronarianos transradiais realizados entre janeiro de 2013 e junho de 2017. A estratégia de um cateter (cateter TIG I) e a estratégia de dois cateteres (cateteres coronários direito e esquerdo de Judkins) foram comparadas. O volume de contraste iodado administrado foi o endpoint primário. Os endpoints secundários eram espasmo radial, duração do procedimento (tempo de fluoroscopia) e exposição a radiações ionizantes (produto dose-área e kerma no ar). Os custos econômicos diretos também foram avaliados. Para as análises estatísticas, valores de p < 0,05 bicaudais foram considerados estatisticamente significativos. Resultados: De um total de 1.953 procedimentos em 1.829 pacientes, 252 procedimentos foram atribuídos à estratégia de um cateter e 1.701 procedimentos à estratégia de dois cateteres. Não houve diferenças nas características basais entre os grupos. A estratégia de um cateter exigiu menos contraste iodado [endpoint primário; (60-105) -mL vs. 92 (64-120) -mL; p < 0,001] em comparação com a estratégia de dois cateteres. Além disso, o grupo da estratégia de um cateter apresentou menos espasmo radial (5,2% vs. 9,3%, p = 0,022) e menor tempo de fluoroscopia [3,9 (2,2-8,0) -min vs. 4,8 (2,9-8,3) -min, p = 0,001] e economia de custos [149 (140-160)-€/procedimento vs. 171 (160-183) -€/procedimento; p < 0,001]. Não foram detectadas diferenças no produto dose-área e kerma no ar entre os grupos. Conclusões: A estratégia de um cateter, com cateter TIG I, melhora o desempenho da coronariografia por cateterismo e reduz os custos econômicos em comparação com a estratégia tradicional de dois cateteres em pacientes encaminhados para cineangiocoronariografia.

ABSTRACT

Abstract The saphenous vein (SV) is the most commonly used conduit for coronary artery bypass surgery (CABG) and the second conduit of choice in Brazil and many other countries. The radial artery (RA) is suggested, by some, to be superior to SV grafts, although its use in the USA declined over a 10 year period. The patency of SV grafts (SVG) is improved when the vein is harvested with minimal trauma using the no-touch (NT) technique. This improved performance is due to the preservation of the outer pedicle surrounding the SV and reduction in vascular damage that occurs when using conventional techniques (CT) of harvesting. While the patency of NT SVGs has been shown superior to the RA at 36 months in one study, data from the RADIAL trial suggests the RA to be the superior conduit. When additional data using NT SVG is included in this trial the difference in risk of graft occlusion between the RA and SV grafts dissipates with there no longer being a significant difference in patency between conduits. The importance of preserving SV structure and the impact of NT harvesting on conduit choice for CABG patients are discussed in this short review.

ABSTRACT

O procedimento da medida indireta da pressão arterial (PA) é usado na prevenção, diagnóstico e tratamento de pacientes com hipertensão arterial nas diversas fases de evolução da doença. Embora o procedimento seja considerado simples e de fácil execução, muitos profissionais realizam-no de forma inapropriada e sem o devido conhecimento científico, o que pode interferir na fidedignidade dos resultados obtidos. Objetivo: Identificar na literatura as falhas no cumprimento da técnica de medida indireta da PA realizada por profissionais de saúde. Método: Trata-se de uma revisão integrativa que analisou estudos publicados entre 2013 e 2017, nas bases de dados Cumulative Index to Nursing and Allied Health Literature, Base de Dados de Enfermagem, Scientific Electronic Library Online, Medical Literature Analysis and Retrieval System, Literatura latino-americana e do Caribe em ciências da saúde, Índice Bibliográfico Espanhol em Ciências da Saúde e Biblioteca COCHRANE. Sete artigos compuseram a amostra do estudo, a qual foi analisada com relação à identificação do artigo, características metodológicas e avaliação do rigor metodológico. Resultados: Cinco estudos foram desenvolvidos no Brasil (71,5%), um no Egito (14,3%) e um nos Estados Unidos (14,3%). Os achados apontaram falhas relacionas à etapa do preparo do paciente, à etapa do procedimento e à etapa do registro da PA. Conclusão: Inúmeras falhas foram identificadas durante a realização do procedimento de medida indireta da PA, o que reforça a necessidade do desenvolvimento de estudos de intervenção que possam promover o conhecimento teórico-prático dos profissionais da saúde


The indirect blood pressure (BP) measurement procedure is used in the prevention, diagnosis and treatment of patients with arterial hypertension in the various phases of disease progression. Although the procedure is considered simple and easy to perform, many professionals perform it incorrectly and without adequate scientific knowledge, which may interfere with the reliability of the results obtained. Objective: To identify in the literature failures in compliance with the technique of indirect BP measurement performed by health professionals. Method: This is an integrated review that analyzed studies published between 2013 and 2017 in the Cumulative Index to Nursing and Allied Health Literature, the Brazilian Nursing Database (BDENF), the Scientific Electronic Library Online, the Medical Literature Analysis and Retrieval System, the Latin American and Caribbean Health Sciences Literature, the Spanish Bibliographical Health Sciences Index, and the COCHRANE Library databases. Seven articles made up the study sample, which was analyzed in terms of article identification, methodological characteristics and assessment of methodological rigor. Results: Five studies were developed in Brazil (71.5%), one in Egypt (14.3%) and one in the United States (14.3%). The findings pointed to failures related to the patient preparation stage, the procedure stage and the BP recording stage. Conclusion: Numerous failures were identified during the indirect BP measurement procedure, which reinforces the need to develop intervention studies that can promote the theoretical-practical knowledge of health professionals

ABSTRACT

Abstract Objective: Over the past 10 years, the rate of patients who have undergone coronary artery bypass graft (CABG) surgery has increased twofold in cases of coronary angiography. Today, transradial access is the first choice for coronary angiography. We aimed to compare the efficacy and reliability of radial versus femoral access for coronary angiography in post-CABG surgery in this study. Methods: Data from 442 patients who underwent post-CABG surgery between 2012-2017 were retrospectively compared. The right radial route was used in 120 cases, the left radial route in 148, and femoral route in 174. These three pathways were compared in terms of procedure time and fluoroscopy time, efficacy, and complication development. Comparisons among the three groups were performed with Bonferroni test for continuous variables and chi-square or Fisher's exact test for nominal variables as a binary. Results: Comparison results indicate that femoral access was better than left radial access and the left radial access was better than right radial access in terms of fluoroscopy time (10.71±1.65, 10.94±1.25, 16.12±5.28 min, P<0.001) and total procedure time (17.28±1.68, 17.68±2.34, 23.04±5.84 min, P<0.001). The left radial pathway was the most effective way of viewing left internal mammary artery (LIMA). No statistically significant differences were found among the three groups in other graft visualizations, all minor complications, total procedure and fluoroscopy time "Except LIMA imaging". Mortality due to processing was not observed in all three groups. Conclusion: The left radial route is preferred over right radial access for post-CABG angiography because the left radial pathway is close to the LIMA and is similar to the femoral pathway. In LIMA graft imaging, right radial access is a reliable route, even though it is not as effective as other pathways. We hope that the right radial pathway will improve with physician experience and innovations.

ABSTRACT

Objetivos: describir la frecuencia de estenosis arterial (cubital y radial) en pa-cientes con esclerosis sistémica (ES); analizar la relación entre estenosis macro-vascular y úlceras digitales. Método: se incluyeron 57 pacientes con ES, según la clasificación del Colegio Americano de Reumatología de 1980 y 21 pacientes sin ES. Se realizó ecografía doppler arterial de miembros superiores. Resultados: la estenosis en al menos una arteria cubital se objetivó en 31% de pacientes con ES (18/57) (p=0.003). Se objetivó estenosis radial en 9 de 57 pacientes con ES (15%) y en uno de los 21 controles (p=0.19). En el modelo multivariado, los predicto-res de úlceras digitales fueron inicio de Raynaud antes de los 40 años (OR 5.3 IC95% 1.54-18.22, p=0.008) y patrón tardío en la capilaroscopia (OR 4.4 IC95% 1.29-15.63, p=0.018). Conclusiones: un tercio de los pacientes ES presentó este-nosis cubital. El compromiso de los grandes vasos no se asoció a úlceras digitales.


Objectives: to describe the frequency of ulnar and radial stenosis in SSc patients. Analyze the correlation between arterial stenosis and digital ulcers. Methods: we included 57 SSc consecutive patients who fulfilled ACR 1980 classification criteria, and 21 healthy controls. An arterial ecodoppler was performed to all participants. Results: the presence of stenosis in at least one ulnar artery was observed in 18 of 57 patients with SSc (31%) and in none of the 21 controls (p=0.003). Stenosis was present in at least one radial artery in 9 of 57 SSc patients (15%) (p=0.19). In multivariate model, the best predictors of digital ulcers were age at onset of Ray-naud phenomenon before 40 years (OR 5.3 95%CI 1.54-18.22, p=0.008) and late SD pattern (OR 4.4 95%CI 1.29-15.63, p=0.018). Conclusion: in the present series, ulnar stenosis was observed frequently in SSc patients. Stenosis of large vessels was not associated with digital ulcers.

ABSTRACT

O presente artigo relata o caso de um paciente coronariopata de 86 anos submetido a cateterismo cardíaco via acesso radial à esquerda. Cerca de 16 meses após o procedimento, manifestou dispneia sem relação com esforço, associada a hipóxia noturna. Apresentava frêmito à palpação do punho esquerdo e foi diagnosticado com fístula arteriovenosa radiocefálica no punho esquerdo. Ao duplex scan apresentava alteração de padrão de onda e aumento da velocidade diastólica compatível com fístula arteriovenosa. Foi submetido a correção cirúrgica da fístula, apresentando melhora clínica e laboratorial após o procedimento. O acesso radial para cateterismo cardíaco tem sido cada vez mais utilizado, principalmente por causar complicações menos frequentes e menos deletérias em comparação ao acesso femoral. Entretanto, complicações como fístula arteriovenosa ocorrem e podem ser especialmente prejudiciais em pacientes octogenários


This article describes the case of an 86-year-old coronary disease patient who underwent cardiac catheterization via a left radial access. Around 16 months after the procedure, he presented with dyspnea, unrelated to effort, but associated with nocturnal hypoxia. There was a palpable thrill in the left wrist and he was diagnosed with a radiocephalic arteriovenous fistula in the left wrist. A duplex scan revealed an abnormal wave pattern and increased diastolic velocity compatible with arteriovenous fistula. The fistula was repaired surgically and the patient exhibited improvement in clinical and laboratory parameters after the procedure. Radial access is increasingly being used for cardiac catheterization, primarily because it is associated with fewer and less harmful complications than femoral access. However, complications such as arteriovenous fistula occur and can be particularly harmful in octogenarian patients

ABSTRACT

The authors report a rare variation of the vasculature in the upper limbs of an 84-year-old male cadaver. A high bifurcation of the brachial artery occurred bilaterally at the proximal one-third of each arm. The radial arteries were larger than the ulnar arteries and gave origin to the common interosseous arteries. At the cubital fossa, the ulnar arteries traversed medial to the median nerves, continuing superficial to all forearm muscles except the palmaris longus tendon, characteristic of superficial brachioulnar arteries. The aforementioned variations have rarely been reported in previous literature and demonstrate important clinical significance in relation to accidental intra-arterial injections, errors in blood pressure readings, as well as orthopedic, plastic, and vascular surgeries of the upper limbs.

ABSTRACT

OBJECTIVE: Aberrant right subclavian artery (ARSA) is a rare anatomical variant of the origin of the right subclavian artery. ARSA is defined as the right subclavian artery originating as the final branch of the aortic arch. The purpose of this study is to determine the prevalence and the anatomy of ARSA evaluated with computed tomography (CT) angiography. METHODS: CT angiography was performed in 3460 patients between March 1, 2014 and November 30, 2015 and the results were analyzed. The origin of the ARSA, course of the vessel, possible inadvertent ARSA puncture site during subclavian vein catheterization, Kommerell diverticula, and associated vascular anomalies were evaluated. We used the literature to review the clinical importance of ARSA. RESULTS: Seventeen in 3460 patients had ARSA. All ARSAs in 17 patients originated from the posterior aspect of the aortic arch and traveled along a retroesophageal course to the right thoracic outlet. All 17 ARSAs were located in the anterior portion from first to fourth thoracic vertebral bodies and were located near the right subclavian vein at the medial third of the clavicle. Only one of 17 patients presented with dysphagia. CONCLUSION: It is important to be aware ARSA before surgical approaches to upper thoracic vertebrae in order to avoid complications and effect proper treatment. In patients with a known ARSA, a right transradial approach for aortography or cerebral angiography should be changed to a left radial artery or transfemoral approach.
