Experiência global no fechamento percutâneo do canal arterial

Abstract

This therapeutic modality is safe and efficacious with good follow-up results.

Percutaneous closure of ductus arteriosus with the amplatzer prosthesis. The Brazilian experience

“…Echocardiography prior to discharge revealed total closure in 30 patients. The 3 remaining patients had a mild residual shunt, which is in accordance with results in previously published protocols 3 . Narrowing of the left pulmonary artery or aorta was not seen in any patient.…”

“…Because of the previous solid experience of both institutions in the percutaneous handling of this defect 1,3,6 , in addition to the excellent intrinsic properties of the prosthesis, we practically had no learning curve. The results found were very good, with a 100% success rate for implantation and total closure.…”

“…Because of the simplicity of the procedure, its low cost, good efficacy, and low rate of complications, the Gianturco coil became the most used device with an undeniable application for short ductus arteriosus [3][4][5] . However, the approach of a ductus arteriosus larger than 3-3.5mm with this method, in addition to the association with a greater rate of embolism, requires adaptations in the implantation technique, multiple devices, and the use of coils for controlled delivery or larger in size [6][7][8][9][10] .…”

“…However, the approach of a ductus arteriosus larger than 3-3.5mm with this method, in addition to the association with a greater rate of embolism, requires adaptations in the implantation technique, multiple devices, and the use of coils for controlled delivery or larger in size [6][7][8][9][10] . The Rashkind umbrella, better indicated for these situations 3 , was recently withdrawn from the market because of its significant degree of residual shunt 11 . After the publication of the results of convincing experimental studies 12 , the Amplatzer prosthesis for percutaneous occlusion of ductus arteriosus was introduced for clinical application with encouraging results 13,14 .…”

Ligadura videotoracoscópica da persistência do canal arterial

“…O fechamento da PCA percutâneo por cateter, oferece algumas vantagens, já que não há incisão, ou anestesia geral (20) , embora a sedação intravenosa seja usual. A permanência no hospital é pequena, em geral ± 24 horas.…”
