ABSTRACT

Fístulas das artérias coronárias têm incidência baixa entre as cardiopatias congênitas, muitas vezes assintomáticas, devendo ser suspeitadas quando há presença de sopro contínuo no precórdio. Podem apresentar sintomas de precordialgia ou insuficiência cardíaca e devem ser estudadas adequadamente para tratamento seguro, tanto cirúrgico como por cateterismo ou acompanhamento clínico. No presente trabalho são relatados três casos tratados por operação com resultado satisfatório e a literatura é revisada

ABSTRACT

During the last eight years a total of nine cases of isolated congenital coronary arteriovenous fistula (CAVF) have been diagnosed at our centre. Age of these patients ranged from 11 days to 22 years (mean 6.4 +/- 4.2 years). There were seven male and two female patients. Right and left coronary arteries were the sites of origin in seven and three cases respectively. One patient had two fistulae, one each originating from right coronary artery and obtuse marginal artery. The drainage sites were right ventricle in seven cases and right atrium in two. The pulmonary artery pressure was normal in eight cases and elevated in one case. The pulmonary artery to systemic flow ratio ranged from 1.1:1-2.4:1 in all except the 11 day-old-baby in whom it was 4:1. Pulmonary vascular resistance (PVRI) was below 3.5 in all cases (range 1.0-3.5 units). Surgical ligation of fistula was done in four cases and two patients underwent coil embolisation of fistula. Follow-up is available in five out of eight patients including three cases in whom CAVF was closed. Two other young patients are being followed-up conservatively and all the patients are asymptomatic. CAVF can present at any age; majority of the cases have small left to right shunts and more commonly CAVF arise from right coronary artery. Surgical ligation of fistula is safe in older patients, non-surgical embolisation using coils may be an alternative to surgery in selected cases.

ABSTRACT

Las fístulas arteriovenosas de tipo congénito que involucran los vasos del cuello son extremadamente raras y sobre todo las de la arteria carótida interna, tomando en cuenta estos antecedentes se decidió revisar la literatura para conocer la incidencia y reportar un caso tratado en el Hospital de Especialidades del Centro Médico Nacional Siglo XXI del Instituto Mexicano del Seguro Social

ABSTRACT

La fístula arteriovenosa pulmonar congénita es la conexión directa de arteriolas pulmonares con vénulas pulmonares sin interposición de capilares. El resultado hemodinámico es un shunt de sangre arterial dentro de una baja resistencia; la magnitud de los efectos periféricos locales y sistémicos dependen de la localización, diámetro y número de comunicaciones vasculares y constituye una rara causa de cianosis en la edad pediátrica. Presentamos un caso clínico de una paciente con fístula arteriovenosa pulmonar postraumática. Femenino de nueve años, iniciando su padecimiento posterior a un traumatismo a nivel de tórax, con cianosis peribucal y en extremidades superiores e inferiores de 18 meses de evolución sin otra sintomatología agregada. Fue valorada en su lugar de origen por los servicios de cardiología, neumología y hematología, sin diagnóstico específico. A su ingreso es valorada integralmente, se realiza electrocardiograma, ecocardiograma, placas radiológicas de tórax, tomografía axial de tórax, broncoscopia y broncografía, con resultados normales. Se realiza centellografía perfusoria pulmonar, reportándose zonas de hipoperfusión difusa e irregular; solicita cineangiografía y se confirma diagnóstico de fístulas arteriovenosas en pulmón izquierdo. Se intervino quirúrgicamente y se realizó lobectomía izquierda. Actualmente su evolución clínica es satisfactoria y no hay evidencias de cianosis

ABSTRACT

La malformación congénita broncopulmonar es una entidad clínica poco frecuente y de difícil diagnóstico, destacan entre los métodos de apoyo la radiología, la tomografía axial computada, la angiografía, el Doppler color y la ultrasonografía. Se presenta una revisión retrospectiva de 10 años con 21 casos de los cuales 13 corresponden a niños menores de 15 años y 8 adultos. Los quistes broncógenos son los más frecuentes (6-28,5 por ciento). En segundo lugar la bronquiectasia quística congénita (5-23,8 por ciento), la malformación adenomatoide quística (4-19 por ciento), el secuestro pulmonar (3-14,2 por ciento), la aplasia pulmonar (2-9,5 por ciento) y la fístula arteriovenosa (1-5 por ciento). Todos fueron intervenidos a excepción de los 2 pacientes portadores de aplasia pulmonar. Se realizaron 12 lobectomías y 7 segmentectomías. Sólo un caso debió reintervenirse por un hemotórax y no hubo mortalidad. El seguimiento ha mostrado excelentes resultados alejados, habiéndose intervenido uno de ellos posteriormente de un ductus persistente

ABSTRACT

The case of a six-day-old neonate admitted in an emergency situation because of dyspnea and increasing cyanosis is reported. Despite abnormal opacification on the chest X-ray and left ventricular overload on the electrocardiogram and echocardiogram, features compatible with the disease, the diagnosis of massive pulmonary arteriovenous fistula affecting the whole left superior lobe, was made possible only after necroscopic examination


É relatado o caso de um neonato com seis dias de vida, encaminhado em caráter de urgência devido à cianose e dispnéia. Apesar da opacificação pulmonar na radiografia simples do tórax e da sobrecarga de câmaras esquerdas no eletrocardiograma e ecocardiograma, dados sugestivos da lesão, o diagnóstico de fístula arteriovenosa pulmonar maciça, envolvendo todo o lobo superior esquerdo, foi estabelecido, somente, através do estudo necroscópico

ABSTRACT

A case of 3 month-old-boy with Down's syndrome and heart failure due to a localized arteriovenous fistula of the cranial vessels is reported. Clinical diagnosis was made after cranial bruit detection based on a retroauricular thrill incidentally felt by the mother. The diagnosis was confirmed by digital subtraction angiography and a good result was achieved by means of embolization and surgical ligation of the fistula. Three years after the operation the patient is asymptomatic, on no medication and with normal magnetic resonance image of the cranial vessels

ABSTRACT

Os autores relatam dois casos de fístula artério-venosa pulmonar (FAVP), um dentre estes associado à síndrome de Rendu-Osler-Weber com múltiplas fístulas, o outro secundário à tuberculose pulmonar. Discutem os achados clínicos e laboratoriais, enfatizando os meios para estabelecer diagnóstico diferencial com outras patologias causadoras FAVP secundária. Discorreu sobre a escolha terapéutica, apontando opçöes emboloterapia ou ressecçäo cirúrgica, confrontando-os com a literatura

ABSTRACT

Criança de 6 meses de idade, assintomática, atendida, inicialmente, devido a edema localizado do membro superior direito. Um sopro contínuo, audível na região infra-clavicular direita, cardiomegalia e hiperfluxo pulmonar estavam associados com uma fístula única entre a artéria e a veia subclávia direita diagnosticada pela angiografia. Ligadura cirúrgica da fístula foi realizada com sucesso, havendo normalização do diâmetro do membro e da área cardíaca do tórax 4 anos após cirurgia


The case of an asymptomatic 6 month-old-boy, first seen due to a right arm edema is described. A continuous murmur heard at the right infraclavicular area, cardiomegaly plus increased flow to the lungs on the chest X-ray were associated with an isolated right subclavian artery-to-vein fistula diagnosed at angiography. Successful ligation of the fistula was done at operation with normalization of the arm circunference and heart size on the chest X-rav at 4 years follow up
