Dilatação por cateter-balão (dacrioplastia) para tratamento das obstruções congênitas do ducto lacrimonasal. Arquivos Brasileiros de Oftalmologia, São Paulo, v. 72, n. 5, p. 669-672, 2009. 0004-2749e- 1678-2925http://repositorio.bc.ufg.br/handle/ri/17616Purpose: To verify the results of balloon-catheter dilatation for the treatment of congenital lacrimal duct obstruction. To the best of author’s knowledge this procedure has not been previously used in Brazil and deserves scientific studies. Methods: Chil- dren between 2 and 5 years old, with congenital lacrimal duct obstruction, were treated with balloon-catheter dilatation (Lacricath ® ). Catheter was introduced by the superior lacri- mal punctum, under general anesthesia. Results: Twenty-seven eyes were treated and 23 presented total improvement of epi- phora signs and symptoms (85.2% success rate). During a one year follow-up, all the procedures had good outcomes, without complications and all the children had 1 year of follow-up. Conclusion: Balloon-catheter dilatation is an efficient and safe procedure and might be used for congenital lacrimal duct obs- truction treatment in children older than 2 years.porAcesso AbertoObstrução dos ductos lacrimais/congênitoCriançasDilatação com balão/métodosLacrimal duct obstruction/congenitalBalloon dilatation/methodsChildrenArtigo10.1590/S0004-27492009000500014
