Introduction The cisterna chyli (CC) is a dilated, bipartite portion of the lymph channel that lies retroperitoneally in association with the cranial abdominal aorta. It drains the visceral and lumbar lymph trunks from the abdominal viscera
combinations of the aforementioned techniques ranges from 20% to 75% in large-scale studies, 10,11 compared with 60% to 100% in dogs. 1,11,12 Cisterna chyli ablation has been described in dogs 1 and cats. 13,14 The cisterna chyli is a confluence of lumbar
In healthy cats and dogs, chyle drains from the intestinal lacteal vessels afferent to the mesenteric lymph nodes and efferent to the cisterna chyli, which lie retroperitoneally dorsal to the abdominal aorta. This milky fluid, composed of lymph
30% is produced by the liver. 13 Mesenteric lymph node injection of nonionic iodinated contrast material has proven useful in delineating the intestinal lymphatic, cisterna chyli, thoracic duct, and its tributaries using CT. 8 – 9 We hypothesized
management is ineffective or impractical. 1 Surgical intervention is warranted in animals with idiopathic chylothorax or those that are not responsive to medical management. 1 Among surgical options, TD ligation, subtotal pericardiectomy, cisterna chyli
also suggest that lymphangiography prior to PCETD is of utmost importance because the location, morphology, and size of the CC and branching of the TD may preclude the use of this technique. ABBREVIATIONS CC Cisterna chyli CrVC Cranial
pericardectomy with or without cisterna chyli ablation for treatment of idiopathic chylothorax in cats A review of medical records for 22 cats that underwent surgery for treatment of idiopathic chylothorax found that the addition of cisterna chyli ablation to
idiopathic chylothorax when other treatments fail, 2,3 including TDL or embolization, diaphragmatic fenestration, thoracic omentalization, pleurodesis, pleurovenous shunting, pericardectomy, cisterna chyli ablation, and various combinations of these
