ABSTRACT
@#Objective Tho evaluate the outcomes of early percutaneous occlusion of these residual major aortopulmonary collateral arteries after heart surgery. Methods This was a retrospective review of children undergoing early percutaneous embolization of major aortopulmonary collateral arteries after cardiac surgery. From January 2013 to February 2017, 52 consecutive patients with postoperative residual major aortopulmonary collateral arteries were treated with percutaneous embolization (38 males, 14 females; median age of 10.0 months, interquartile range 14.0 months; median weight 8.6 kg, interquartile range 4.4 kg). Fifty-one patients were cyanotic and 1 patient was acyanotic. Forty-nine patients underwent corrective surgery and 3 patients underwent B-T shunt. Results Typical symptoms and signs of major aortopulmonary collateral arteries included: elevated left atrial pressure; focal lung infiltration, pink or blood-stained frothy sputum. The median time interval from cardiac surgery to percutaneous occlusion of major aortopulmonary collateral arteries was 5 (9) d, median duration of mechanic ventilation support since occlusion was 72 (159) h, mechanic ventilation support was 239 (480) h and median duration of intensive care unit was 19 (29) d. There was no death in this group. Conclusion Angiocardiography could be able to demonstrate the existence of postoperative major aortopulmonary collateral arteries. The early percutaneous occlusion appears to be simple, safe and effective.
ABSTRACT
A anticoagulação com varfarina é eficaz na redução do risco de eventos cardioembólicos nos pacientes com fibrilação atrial,entretanto, diversos fatores podem limitar seu uso. A oclusão percutânea do apêndice atrial esquerdo representa um método minimamente invasivo, que pode ter resultados semelhantes aos da varfarina, na prevenção de eventos cardioembólicos em pacientes de maior risco. Relatamos os aspectos do ecocardiograma transesofágico em um paciente com fibrilação atrial permanente, com repetidos episódios tromboembólicos e dificuldade em atingir adequado controle laboratorial com o uso da anticoagulação oral e submetido à oclusão percutânea do apêndice atrial esquerdo.
Anticoagulation with warfarin is effective in reducing the risk of cardioembolic events in patients with atrial fibrillation, however, several factors may limit its use. The percutaneous closure of the left atrial appendage is a minimally invasive method that may have results similar to warfarin in the prevention of cardioembolic events in high risk patients. We describe the transesophageal echocardiographic features in a patient with persistente atrial fibrillation, with repeated thromboembolic episodes and difficulty in achieving adequate laboratory control with the use of oral anticoagulation, submitted to percutaneous occlusion of the left atrial appendage.
La anticoagulación con warfarina es eficaz en la reducción del riesgo de episodios cardioembólicos en los pacientes con fibrilación auricular, y sin embargo, diversos factores pueden limitar su uso. La oclusión percutánea del apéndice auricular izquierdo representa un método mínimamente invasivo, que puede dar resultados semejantes a los de la warfarina, para la prevención de episodios cardioembólicos en pacientes de mayor riesgo. Relatamos los aspectos del ecocardiograma transesofágico en un paciente con fibrilación auricular crónica, con repetidos episodios tromboembólicos y dificultad para conseguir un adecuado control de laboratorio con el uso de la anticoagulación oral y sometido a la oclusión percutánea del apéndice auricular izquierdo
