RESUMO

The ligamentum arteriosum is a remnant of the ductus arteriosus, which connects the aortic arch and the pulmonary trunk during fetal life. Variation in the anatomy of the ligamentum arteriosum, its connections with the aorta and pulmonary trunk and the course of the left recurrent laryngeal nerve relative to the ligamentum arteriosum were investigated. Dissection of the superior mediastinum was performed on 40 cadavers. The anatomy of the ligamentum arteriosum and its relationship to the aortic arch, pulmonary trunk and left recurrent laryngeal nerve were documented. The dimensions of the ligamentum arteriosum were measured with a caliper. Ligamenta arteriosa in which presence of a lumen was suspected were examined histologically. Variation in the structure and size of the ligamenta arteriosa was found to be common. A 'line' on the luminal surface of the aorta at the attachment site of the ligamentum arteriosum was observed in 26%. A shallow fossa or depression was found on the luminal surface of the pulmonary trunk in all but one individual. The left recurrent laryngeal nerve was situated lateral to the ligamentum arteriosum in 97%. Variation in the anatomy of the ligamentum arteriosum was found to be common, whereas variation in the position of the left recurrent laryngeal nerve was rare. This information is relevant for surgeons to avoid accidental injury to variant structures. Remnants, in the form of 'lines' or depressions, of the anatomical association between the ductus arteriosus and the aorta and pulmonary trunk were present

RESUMO

INTRODUCCIÓN: El ductus arterioso persistente (DAP) es frecuente en prematuros. Su cierre quirúrgico puede causar parálisis de cuerda vocal izquierda (PCVI) por lesión del recurrente. MATERIAL Y MÉTODOS: Estudio retrospectivo de prematuros con DAP de nuestro centro entre 1999-2013. Revisamos sus características y complicaciones de tratamiento. En los pacientes intervenidos se realizó una encuesta sobre síntomas relacionados con PCVI y se ofertó realizar una laringoscopia. RESULTADOS: Revisamos 88 pacientes diagnosticados de DAP en el período de estudio. Doce (13,64%) precisaron cirugía, los de menor edad gestacional y peso al nacer, teniendo mayor necesidad de ventilación mecánica e incidencia de parálisis diafragmática, displasia broncopulmonar y hemorragia intraventricular. El 33,3% (3/9) de los pacientes intervenidos tuvieron PCVI, presentando disfonía todos ellos (100 vs 16,7%, p = 0,05). DISCUSIÓN: La PCVI es una complicación frecuente de la cirugía del DAP. Serían necesarios más estudios que aclaren sus factores de riesgo y consecuencias a corto y largo plazo


INTRODUCTION: Patent ductus arteriosus (PDA) is a common problem in preterm newborns. Left vocal cord paralysis (LVCP) can complicate surgical closure if the recurrent nerve is damaged. MATERIALS AND METHODS: A retrospective case series study was conducted on preterm babies diagnosed with PDA in our unit from 1999 to 2013. Their clinical features and treatment complications were reviewed. In those patients that received surgical treatment a telephone uestionnaire on the symptoms of LVCP symptoms was completed, and laryncoscopy examination offered. RESULTS: A total of 88 subjects diagnosed with PDA were found, of whom 13.64% (12/88) needed surgery. These patients had a lower gestational age and birth weight. They required mechanical ventilation more frequently, and they had more complications such as, diaphragmatic paralysis, bronchopulmonary dysplasia and intraventricular hemorrhage. One third (3/9) of the surgically treated patients had LVCP, and all of them had dysphonia (100% vs. 16.7%, p = .05). DISCUSSION: LVCP is a common complication of PDA surgery. Further studies are needed to determine its risk factors and its short and long-term consequences

RESUMO

La constricción intrauterina del ductus arterioso es un evento raro, que a menudo resulta en una grave morbilidad fetal/neonatal y en mortalidad. La constricción del ductus fetal surge generalmente asociada a la exposición materna a los antiinflamatorios no esteroideos o a lesiones estructurales cardíacas. El pronóstico depende del grado y el intervalo de la obstrucción del flujo ductal. Para identificar la causa detrás de este diagnóstico se requiere generalmente la realización de una anamnesis detallada. En este artículo presentamos 2 casos de fetos con constricción del ductus arterioso diagnosticados por ecocardiografía rutinaria del tercer trimestre. El consumo excesivo de té negro y de hierbas fue identificado como la causa de la constricción del ductus arterioso. Alrededor de 2 semanas después de interrumpir el consumo de dichas sustancias, la constricción ductal se invirtió y los valores hemodinámicos han vuelto a la normalidad. Las mujeres embarazadas y los médicos deben ser sensibles a los efectos de los consumos en exceso de alimentos con altas concentraciones de polifenoles(AU)


Intrauterine constriction of ductus arteriosus is a rare event which often results in severe fetal/neonatal morbidity and mortality. Fetal ductus constriction is usually associated with maternal exposure to non-steroidal anti-inflammatory drugs or structural cardiac lesions. The prognosis depends on the degree and interval of ductal flow obstruction. Detailed history taking is generally required to identify the cause of this diagnosis. We report two cases of fetuses with ductus arterious constriction diagnosed by routine echocardiography in the third- trimester. The cause of the ductus arterious constriction was identified as excess consumption of black and herbal tea. Around 2 weeks after stopping consumption of these substances, ductal constriction was reversed and hemodynamic values returned to normal. Pregnant women and clinicians should be sensitized to the effects of excess consumptions of foods with high concentrations of polyphenol(AU)

RESUMO

La existencia de un ductus arterioso fetal aneurismático es un diagnóstico infrecuente. Los motivos pueden ser varios. No se trata de una de las cardiopatías fetales que se busque rutinariamente y, en general, es una entidad poco conocida y de aparición rara. Sin embargo, saber de su existencia de forma prenatal es importante, pues tras el nacimiento puede causar una clínica que es preciso reconocer. Se presenta un caso de diagnóstico fetal con las imágenes correspondientes (AU)


The existence of an aneurysmatic ductus arteriosus, is rarely diagnosed. There may be several reasons. It is not one of the routinely looked for foetal heart diseases, and is generally a liitle known condition that rarely occurs. However, to be aware of its existence in the prenatal stage is important as it may cause an post-natal illness that requires a diagnosis. A case is presented of a foetal diagnosis along with its images (AU)

RESUMO

El cierre quirúrgico del conducto arterioso en adultos implica riesgos debido a sus cambios anatómicos e histológicos. Desde octubre de 1992 hasta agosto de 2008, fueron referidos a nuestro servicio 23 pacientes con conducto arterioso persistente aislado; edad, 16-75 años (mediana, 25,5); peso, 52-80 kg (mediana, 57); diámetro pulmonar, 1,8-5,8 mm (media, 3,5); presión media en la arteria pulmonar, 9-72 mmHg (media, 15). Las tasas de oclusión fueron del 85,7% con los dispositivos Rashkind-PDA y del 100% con Amplatzer Duct-Occluder y Nit-Occlud coil. Tiempo medio de internación y seguimiento: 24 h y 2 años respectivamente. La única complicación inmediata fue un hematoma inguinal; no hubo complicaciones alejadas. En adultos, el cierre del conducto arterioso con diferentes dispositivos, especialmente los de última generación, resultó seguro y eficaz, independientemente de su morfología y estado histológico (AU)


Surgical closure of patent ductus arteriosus in adults involves a number of risks because there are associated anatomic and histologic alterations. Between October 1992 and August 2008, 23 patients were referred to our department with isolated patent ductus arteriosus. Their age ranged from 16-75 years (median 25.5 years) and their weight from 52-80 kg (median 57 kg). The pulmonary diameter ranged from 1.8-5.8 mm (mean 3.5 mm), and pulmonary artery pressure, from 9-72 mmHg (mean 15 mmHg). The rate of ductal occlusion achieved with the Rashkind patent ductus arteriosus occluder was 85.7%, and it was 100% with the Amplatzer duct occluder and the Nit-Occlud coil. The average hospitalization time and follow-up duration were 24 hours and 2 years, respectively. The only immediate complication was an inguinal hematoma, and there were no late complications. In adults, closure of patent ductus arteriosus using a number of different devices, especially the latest generation devices, was safe and effective, regardless of morphologic and histologic characteristics (AU)

RESUMO

Los dispositivos Amplatzer se utilizan en el tratamiento percutáneo de la comunicación interauricular ostium secundum (CIA-OS), el ductus arterioso persistente (PDA) y la comunicación interventricular muscular (CIV-m). Hay muy poca experiencia con estos dispositivos en niños menores de 1 año. Entre enero de 2001 y enero de 2008 se trató a 22 niños menores de 1 año sintomáticos; 3 tenían CIA-OS; 15, PDA y 4, CIV-m. Todos los procedimientos fueron exitosos. No observamos complicaciones inmediatas o a mediano plazo. El cierre percutáneo de estos defectos con dispositivos Amplatzer es una técnica eficaz y segura en niños menores de 1 año sintomáticos que de otro modo requerirían cirugía (AU)


Amplatzer devices are used for the percutaneous closure of ostium secundum atrial septal defects, muscular ventricular septal defects, and patent ductus arteriosus. However, very little experience has been gained in using these devices in infants under 1 year of age. Between January 2001 and January 2008, 22 symptomatic infants aged under 1 year underwent percutaneous treatment: three had an ostium secundum atrial septal defect, 15 had patent ductus arteriosus, and 4 had a muscular ventricular septal defect. All the procedures were completed successfully. No immediate or medium-term complications were observed. Closure of these types of defect using an Amplatzer device in infants under 1 year of age, who would otherwise require surgery, is a safe and effective procedure (AU)

RESUMO

Se presentan los datos de dos estudios que comparan el tratamiento quirúrgico con el intervencionista en dos grupos de pacientes adultos, uno con comunicación interauriculary otro con persistencia del conducto arterioso. En ambos grupos, el tratamiento intervencionista fue superioral quirúrgico en cuanto a la seguridad del paciente, con menores complicaciones a corto y largo plazo (AU)


We present the results of two studies that compared surgical treatment and percutaneous intervention in two groups of adult patients: one with atrial septal defects and the other with patent ductus arteriosus. In both groups, percutaneous intervention was superior to surgery in terms of patient safety, with fewer immediate and long-term complications (AU)

RESUMO

Presentamos un caso de aneurisma congénito del ductus arteriosos con insuficiencia cardiaca neonatal e imagen de masa paracardíaca izquierda en la radiografía de tórax, diagnosticado mediante ecocardiografía y confirmado con angiografía. La paciente fue intervenida sin complicaciones, realizándose exéresis del aneurisma y cierre del ductus. En la evolución se diagnosticó de síndrome de Beals-Hetch. Tras seis años de seguimiento, la paciente está asintomática y con normalidad cardiovascular determinada por ecocardiografía (AU)


We report a case of aneurysm of the ductus arteriosus present with heart failure in the neonatal period. The chest x-ray showed an enlarged heart together with a left paracardiac mass. The echocardiogram showed an aneurysmatic patent ductus arteriosus, confirmed by angiography. The condition was successfully corrected by surgery without complications. In the follow-up a Beals-Hetch syndrome was diagnosed. After 6 years of follow-up, the patient remains symptoms free with normal echocardiographic data (AU)

RESUMO

El tronco arterioso común (TA) se trata de una cardiopatía congénita (CC) caracteriza por la salida de un único gran vaso, del que a su vez serán ramas las arterias pulmonares. Típicamente se produce un acabalgamiento u overriding de este gran tronco arterial sobre el septo interventricular. También es conocida como tronco aortopulmonar, TA común o TA persistente, aludiendo este término al hecho de que el TA es una situación normal en las primeras semanas de desarrollo y lo que es patológico es su persistencia. Presentamos un caso clínico y sus manifestaciones intraútero (AU)


Common trunk is a kind of congenital heart disease characterized by a great alone vessel within pulmonary arteries are comming from. Typically that great trunk is overriding the ventricular septum. This condition is also knowm as aorto-pulmonary trunk, commom trunk or persistent trunck. We report a case and describe the prenatally features of this condition (AU)
