摘要: Chylous leaks, such as chylothorax and chylopericardium, are uncommon effusions resulting from the leakage of intestinal lymphatic fluid thoracic duct (TD) its tributaries, or ducts. The cause can be either traumatic (thoracic surgery) nontraumatic (idiopathic, malignancy). Treatment has traditionally consisted dietary modification (nonfat diet) and/or surgery (TD ligation, pleurodesis). Thoracic embolization (TDE) become a viable treatment alternative due to it high success rate minimal complications. In this article, authors describe etiologies chylothorax, patient population, outcomes, long-term follow-up TDE patients. Relevant anatomy physiology reviewed, with special attention paid formation by tributaries at cisterna chyli (CC). technique is outlined, including bilateral pedal lymphangiography, TD cannulation, embolic agents used for procedure.
