          Abstract

          Resumen El arco aórtico izquierdo con arteria subclavia derecha aberrante (ARSA) es la anomalía más frecuente del arco aórtico. El diagnóstico prenatal mediante ecocardiografía ha permitido su diagnóstico precoz, pero sigue siendo generalmente un diagnóstico incidental. La mayoría de los casos son asintomáticos, pero una proporción de pacientes cursa con disfagia de predominio para sólidos. En menor medida puede provocar fallo de medro o clínica respiratoria por compresión extrínseca de la vía aérea. El diagnóstico se suele realizar mediante estudio esófago-gastroduodenal con contraste baritado, y otras técnicas útiles son la tomografía computarizada (TC) y la resonancia magnética (RM) con angiografía, así como el ecocardiograma con Doppler color. El tratamiento de elección en pacientes sintomáticos es la cirugía.

          Abstract Left aortic arch with aberrant right subclavian artery is the most frequent anomaly of the aortic arch. Prenatal diagnosis through echographic imaging has allowed early diagnosis, but the entity still remains mainly an incidental finding. Most cases are asymptomatic, but a subset of patients suffer from dysphagia with the intake of solid food. In a small percentage it can cause poor weight gain or respiratory symptoms secondary to extrinsic compression of the airway. Diagnosis relies usually in oesophagography with barium contrast, although computerized tomography and magnetic resonance with angiography have also shown to be useful, as well as echocardiogram with colour Doppler. Surgery is the preferred treatment option for symptomatic patients.

          Arteria lusoria: developmental anatomy, clinical, radiological and surgical aspects.

          The left aortic arch with an aberrant right subclavian artery, or arteria lusoria, is the most common aortic arch anomaly, occuring in 0.5-2.5% of individuals. Four vessels arise sequentially from the aortic arch: the right common carotid artery, the left common carotid artery, the left subclavian artery and the aberrant right subclavian artery, which crosses upwards and to the right in the posterior mediastinum. It results from a disruption in the complex remodelling of the paired branchial arches, typically of the right dorsal aorta distal to the sixth cervical intersegmental artery. The diagnosis and differentiation of arch anomalies is based on findings at chest radiography in association with those at esophagography. It is usually asymptomatic. When symptomatic, it produces dysphagia lusoria or dyspnea and chronic coughing. Treatment is indicated for symptomatic relief of dysphagia lusoria and for prevention of complications due to aneurysmal dilatation.

            The aberrant right subclavian artery: cadaveric study and literature review.

            Taking into consideration that the aberrant right subclavian artery (ARSA) is the commonest congenital aortic arch anomaly (prevalence 0.16-4.4%), our goal was to investigate its incidence in Greeks, with respect to location, course, and relationship to trachea and esophagus. Gender dimorphism, coexisting neural, and vascular variations were also examined. The clinical impact and embryological background of the variation are discussed.

              Prenatal diagnosis of aberrant right subclavian artery in an unselected population

              Purpose The purpose of this study was to determine the frequency of aberrant right subclavian artery (ARSA) among unselected fetuses and to evaluate its association with chromosomal abnormalities and other congenital anomalies. Methods In all, 7,547 fetuses (gestational age, 20 to 34 weeks) were examined using routine antenatal sonography at our institution between April 2014 and September 2015. The right subclavian artery was assessed using grayscale and color Doppler ultrasonography in the transverse 3-vessel and tracheal view, and confirmed in the coronal plane. Results ARSA was found in 28 fetuses (0.4%). Further, 27 of these 28 fetuses were euploid (96.4%). Trisomy 18 was the only chromosomal anomaly (3.6%) found in the study sample. ARSA was an isolated finding in 23 of the 28 cases (82.1%). In the remaining three cases (10.7%), ARSA was accompanied with extracardiac anomalies. Other cardiac defects were present in three cases (10.7%). Conclusion Isolated ARSA does not seem to be associated with a significantly increased risk of aneuploidy. However, the possibility of fetal karyotyping, which is a more invasive procedure, should be discussed in the light of the overall risk of the fetus.
