“…Chahwan et al (2006) presenta un caso de ausencia de TBC con la arteria subclavia derecha naciendo de la parte media del arco aórtico. También Biasutto et al 2012, McDowell et al (1980), Chaoui et al (2005 y Natsis et al (2011) publicaron casos donde el vaso estaba ausente; en la mayoría de los casos, la ausencia se debe a una arteria subclavia derecha aberrante (Fig. 2).…”

Las anomalías y variaciones anatómicas del tronco braquiocefálico (TBC) pueden tener importantes implicancias en la práctica médica, en especial en la interpretación de estudios de diagnóstico por imágenes, en procedimientos quirúrgicos torácicos y cervicales, e incluso pueden ser incompatibles con la vida. Nuestro objetivo es realizar una revisión que permita considerar las variaciones anatómicas del TBC y sus manifestaciones clínicas a partir de la bibliográfica relacionada a hallazgos anatómicos y estudios clínicos. Realizamos una extensa búsqueda bibliográfica y sintetizamos los resultados obtenidos considerando las anomalías en el origen, el recorrido y la distribución del TBC. Acompañamos la información anatómica con los datos correspondientes a las manifestaciones clínicas que presentaron y algunos procedimientos terapéuticos que se encuentran descriptos en la literatura.Knowledge of anatomical anomalies and variations on the brachiocephalic trunk is important in medical practice, mainly for the interpretation of diagnostic images, in surgical procedures of thorax and neck, and may also be of high risk for life. Our objective was to perform a review to consider the anatomical variations of the brachiocephalic trunk and the clinical expressions published in the literature, most of them as eventual findings. We carried on a wide literature research and summarized the results considering the anomalies at the origin, in the way and in the braching of the brachiocephalic trunk. The anatomical information was associated to the clinical aspects presented in the published papers and some therapeutic procedures described in the literature.

“…Many authors include some embryological aspects of the BCT in their descriptions, some discrepancies appearing among those who state that the BCT and the subclavian artery originate from the 4 th aortic arch (Savastano et al, 2002;Smith Agreda et al, 1992;Williams and Warwick, 1992) and others who associate their origin with the aortic sac (Moore, 1982;Sadler and Langman, 2005). Embryological features determine anatomical variations and anomalies that often occur in the BCT : 1) at its origin, such as a common origin with the left common carotid artery (Chahwan et al, 2006;Jakanani and Adair, 2010;Katz et al, 2006;Moskowitz and Topaz, 2003;Turgut et al, 2001), coming from any of the pulmonary arteries (Gil-Jaurena et al, 2011;Martin et al, 2006) or absence (Chaoui et al, 2005;McDowell et al, 1980;Natsis et al, 2011), 2) in length and anatomical relations (Hori et al, 2004;Maldjian et al, 2007;Ozlugedik et al, 2005;Racic et al, 2005), 3) in its branching, such as the observed origination of a coronary artery (Davies and Lie, 1977;Duran et al, 2008), a pulmonary artery (Hung et al, 2001;Tsutsumi et al, 1991), a thyroidea ima artery (Yilmaz et al, 1993) and others. Most of the BCT-related publications are case reports, usually on anatomic anomalies with clinical consequences, or on diagnostic and surgical findings.…”

Las características de la división arterial representan un factor de riesgo para la oclusión arterial y causa frecuente de dificultad para la cateterización. Su forma de presentación depende de la unión del 3º y 4º arcos aórticos. Con el objetivo de evidenciar las caracterís-ticas del tronco braquiocefálico (TBC) se estudiaron 40 fetos de entre 12 y 23 semanas de gestación. Se disecaron los grandes vasos y el TBC fue seccionado en su origen y resecado conjuntamente con la porción proximal de las arterias carótida común derecha (CCD) y subclavia derecha (SD). Se midió la longitud, el ancho y los ángulos interno y geométrico entre las arterias CCD y SD. Abrimos las arterias para observar la luz vascular. Se documentó fotográficamente. La longitud promedio fue de 4,25 mm y el ancho promedio de 1,53 mm. No se evidenció relación directa entre las medidas de los TBC y la edad fetal. La mediana del ángulo interno fue de 62º. Sólo el 50% de los TBC pudieron ser abiertos, permitiendo observar la presencia de tabiques parciales entre ambos vasos en el 20% de los casos y de espolones a nivel de la bifurcación en otro 10%. No hallamos descripciones sobre estos relieves en la literatura. El ángulo interno entre ambas arterias fue significativa-mente mayor en los casos que presentaron relieves. En conclusión, la presencia de relieves en la superficie interna del TBC tiene origen embriológico y representaría un factor importante de riesgo para patología obstructiva vascular y causa de dificultad para la cateterización. Arterial division features constitute risk factors for arterial occlusion and frequently cause difficulties in catheterization. In this case the relevant feature is the junction of the 3rd and 4th aortic arches. With the aim of displaying the features of the brachiocephalic trunk (BCT), we studied 40 fetuses of between 12 and 23 weeks of gestation. Great vessels were dissected and the BCT was cut and resected at its origin within the proximal portion of the right common carotid (RCC) and right subclavian (RS) arteries. The arteries were opened to observe their internal surface. Findings were documented photographically. In each case, the internal and geometric angles were measured. Their average length was 4.25 mm, and average width was 1.53 mm. There was no evidence of a direct relationship between the measurements of the BCT and fetal age. The median value of the internal angle was 62º. Only 50% of the BCT could be opened, allowing the observation of a partial septum in 20% of the cases, or ridges at the arterial bifurcation in another 10%. No descriptions of these formations were found in the literature. The average internal angle between both arteries (RCC and RS) was significantly greater in those cases having intraluminal formations. In conclusion, formations on the inner surface of the BCT are of embryological origin and represent a major risk factor for vascular obstructive disease and a cause of difficulty in catheterization.

Single arterial trunk arising from the aortic arch.

Abstract: A 59-year-old male with a single, arterial trunk arising from the aortic arch is reported. No orther cases of this anomaly have been confirmed; a review of the literature does not reveal another reported case of this abnormal arterial configuration.
