Chylothorax

icanis

Introduction

  • Cause: trauma to thoracic inlet, thoracic neoplasia, lymphatic hypertension, heart failure, dirofilariasis. However, many cases in dogs are considered idiopathic.
  • Signs: depend on volume and rate of chyle accumulation; dyspnea is most common with marked forceful inspiration and delayed expiration; coughing if chronic.
  • Diagnosis: thoracocentesis and fluid/aspirate analysis.
  • Treatment: ideally, attention to underlying cause. However, most are idiopathic and treatment focuses on occlusion of thoracic duct.
  • Prognosis: variable response to both surgical and medical managements limits the prognosis. In addition, longstanding chylous effusion can result in fibrosing pleuritis (lung cortication) and possible restrictive pericarditis.
