RESUMO
A 4-year-old castrated male Golden Retriever was referred for evaluation of intermittent purulent discharge from the right eye of 4-months' duration. A radiolucent area in the maxillary bone was detected on examination of skull radiographs. Dacryocystorhinography revealed pooling of contrast material in the radiolucent area. A rhinotomy was performed, and a large opening between the cystic structure of the nasolacrimal system and the nasal cavity was created. Epiphora resolved after surgery and had not recurred by 9 months after surgery. Two other dogs had cystic structures of the nasolacrimal system and were treated surgically to allow drainage into the nasal cavity.

A 2-year-old Bernese Mountain Dog was examined to determine the cause of bilateral pleural effusion. Torsion was diagnosed, and a lobectomy of a lung lobe was performed. Chylothorax developed 12 days after lung lobectomy. Mesenteric lymphangiography revealed lymphangiectasis Lymphangiography immediately after surgical thoracic duct was completely obstructed, but chylothorax persisted after thoracic duct ligation. Lymphangiography was repeated 50 days after ligation of the thoracic duct and revealed multiple patent thoracic duct branches and progressive lymphangiectasis. A second attempt to ligate the thoracic duct caused the effusion to become serosanguineous. A pleuroperitoneal shunt with a manually operated pump chamber was used to remove the pleural effusion. Chylothorax was again detected 50 weeks after placement of shunt. Mesenteric lymphangiography revealed multiple patent thoracic duct branches and a lymphatic plexus that extended across the thoracic cavity.

Mesenteric lymphangiography and thoracic duct ligation were performed on 19 cats with chylothorax between 1987 to 1992. Chylothorax was diagnosed on the basis of detection of chylomicrons in the pleural effusion or determination of a cholesterol concentration:triglyceride concentration ratio of < 1 in the pleural fluid. Preoperative medical treatment consisted of thoracentesis (19 of 19 cats) and feeding a fat-restricted diet (14 of 19 cats). Positive-contrast mesenteric lymphangiography was performed before thoracic duct ligation to identify an underlying cause for the effusion. Lymphangiectasia was diagnosed by use of radiography in 17 cats, none of which had evidence of a thoracic duct rupture. Thoracic duct ligation was performed via an incision made through the left 10th intercostal space. Lymphangiography was repeated immediately after ligation of the thoracic duct to document occlusion of all branches. Follow-up monitoring was done for 12 to 47 months (median, 28 months) and consisted of physical examination, evaluation for clinical signs related to pleural effusion, and thoracic radiography. Ten of 19 (53%) cats had complete resolution of pleural effusion. Nonchylous effusion, localized in the right hemithorax, was detected in 1 cat 2 months after thoracic duct ligation, but resolved after thoracotomy, breakdown of thoracic adhesions, and expansion of the right cranial lung lobe. Chylous effusion resolved 3 to 7 days (mean, 5.4 days) after surgery in the 10 cats that survived > 12 months after surgery. Four cats died between 2 and 13 days after thoracic duct ligation, but pleural effusion had resolved in 3 of these 4 cats at the time of death.(ABSTRACT TRUNCATED AT 250 WORDS)

A 2.5-year-old rhesus monkey was examined because of a bony enlargement of the distal portion of the right tibia. On the basis of radiographic and histologic findings, enchondroma was diagnosed. The tumor enlarged over the next 2 years, but the monkey continued to have normal use of its limb.
