ABSTRACT

Abstract Aortic arch anomalies are not clinically important unless they cause compression symptoms due to aneurysmatic dilatation. Aortic anomalies need to be treated when they cause complex thoracic aortic diseases, and the treatment approach has evolved over time from open surgical methods, which have high mortality and morbidity rates, to hybrid methods. A case of a 68-year-old male patient with complex aortic arch anomaly treated with hybrid arch repair is reported in this study. Aortic branches were common carotid trunk and aberrant right subclavian artery with a saccular aneurysm.

ABSTRACT

Objetivos: Dentro de las malformaciones vasculares de las arterias en el tórax encontramos: 1) doble arco aórtico; 2) arco aórtico derecho y conducto arterioso izquierdo persistente; 3) arteria subclavia derecha aberrante; 4) arteria pulmonar izquierda aberrante, y 5) arteria innominada anómala. Se revisan los pacientes con arteria subclavia derecha aberrante y su manejo. Métodos: Se estudiaron en forma retrospectiva los expedientes de 29 pacientes en edad pediátrica, de enero de 1992 a diciembre 2012, con las siguientes variables: edad de inicio de los síntomas, manifestaciones clínicas, defectos cardiovasculares, método diagnóstico y abordaje quirúrgico. Resultados: El mayor número de pacientes cursó de forma asintomática, únicamente el 31% lo hizo con síntomas durante el primer año de vida, y se llevó a cabo el diagnóstico en un 35% mediante cateterismo. Fue la persistencia del conducto arterioso la cardiopatía más frecuente, con un 13%; el síndrome de Down se encontró en un 21% de los pacientes. El tratamiento más utilizado fue la sección de la arteria subclavia aberrante para la liberación del esófago. Conclusiones: Es importante la sospecha diagnóstica en pacientes con sintomatología durante la alimentación, con trastornos de la deglución con sólidos y, en algunos casos, con disfagia o hasta con dificultad respiratoria. Un número significativo de estos pacientes no son diagnosticados oportunamente, algunos alcanzan la edad adulta sin diagnóstico. El hallazgo de esta malformación ocurre durante los estudios de imagen, cuando se evalúa la aorta o en el estudio del reflujo gastroesofágico, ya que con el trago de bario se aprecia la compresión extrínseca del esófago.


Objectives: Congenital vascular malformations of the major arteries in the chest have been classified into 5 groups: 1) double aortic arch; 2) right aortic arch with left ligament or persistent ductus arteriosus; 3) aberrant subclavian artery; 4) aberrant left pulmonary artery, and 5) anomalous innominate artery. We reviewed the patients with aberrant right subclavian artery and their treatment. Methods: We studied retrospectively the records of 29 patients with aberrant right subclavian artery in childhood, from January 1992 to December 2012, analyzing the following variables: age at onset, clinical manifestations, associated cardiovascular defects, diagnosis and surgical approach method. Results: We found that most patients have an asymptomatic course, only 31% of them course with symptoms during the first year of life, with an incidental diagnosis of 35% during catheterization or other imaging studies. Patent ductus arteriosus was the most frequently associated congenital malformation, with 13%. Down's syndrome was found in 21%. The most common treatment was surgical section of the aberrant subclavian artery to release the esophagus. Conclusions: This vascular abnormality must be suspected in those patients with dysphagia, dyspnea, chest pain during feeding or breathing difficulties. A significant number of patients are not diagnosed in time, some reach adulthood without a diagnosis. This malformation is often found in imaging studies when evaluating the aorta or in a gastroesophageal reflux study, in which the barium bolus reveals the extrinsic compression of the esophagus.

ABSTRACT

La hipotermia durante la circulación extracorpórea es un método común en cirugía cardiovascular infantil. La normotermia fue iniciada por Lecompte en 1995. Se realizó un estudio prospectivo y aleatorio en 100 niños mayores de 30 días, con el objetivo de evaluar los cambios hemodinámicos en normotermia e hipotermia. En normotermia se utilizó temperatura de 36 ºC, hematocrito mayor de 30 por ciento y flujo entre 2,8 y 3,5 litros/minuto/m² de superficie corporal. En hipotermia, hematocrito entre 24 y 30 por ciento y flujo entre 2,4 y 2,8 litros/minuto/m². En normotermia el tiempo de circulación extracorpórea y los valores de ácido láctico fueron significativamente menores, mientras la saturación venosa central fue mayor, al final de la extracorpórea y a las 6 horas en terapia intensiva. En normotermia el índice cardiaco fue significativamente mayor a las 6 horas y los índices de inotrópicos, menores a las 24 horas. La normotermia protege los órganos de manera segura y eficaz


Hypothermia during the extracorporeal circulation is a common method in pediatric cardiovascular surgery. The normothermia was started by Lecompte in 1995. A randomized and prospective study was conducted in 100 children aged over 30 days to assess the hemodynamic changes in normothermia and hypothermia. In normothermia a temperature of 36 ºC, hematocrit higher than 30 percent and a flow between 2,8 and 3,5 liter/min/m² were used. In hypothermia, hematocrit between 24 and 30 percent and a flow between 2,4 and 2,8 liters/min/m². In normothermia extracorporeal circulation time and values of lactic acid were very lower, whereas the central venous saturation was higher at the end of extracorporeal one and at 6 hours in intensive therapy. In normothermia heart rate was higher at 6 hours and the rates of inotropics rates were lower at 24 hours. Normothermia protects the organs in a safe and effective way
