Although the exact pathophysiology of primary chylopericardium has not been established, the reflux of chylous fluid into the pericardial space was suggested as the etiology. Damage to the thoracic duct valves and the communication of the thoracic duct to the pericardial lymphatics or abnormally elevated pressure in the thoracic duct could cause chylous fluid reflux. In this report, we described the case of a 4-year-old boy with primary idiopathic chylopericardium presenting as cardiac tamponade who was treated with video-assisted thoracoscopic window and then surgical duct ligation.eninfo:eu-repo/semantics/closedAccessIdiopathic chylopericardiumDuct ligationVideo-assisted thoracoscopyWindowChildrenArticle3956446462514644910.1007/s00059-013-3875-22-s2.0-84907437328Q3WOS:000341095500017Q4
