Thoracocentesis

obovis

Synonym(s): thoracentesis, pleural fluid drainage


Introduction

  • Thoracocentesis is indicated where there is evidence of pleural effusion and collection is necessary to undertake examination of the fluid (physical, biochemical, cytologic and bacteriologic). 
  • However, this procedure is rarely performed in cattle, as large accumulations of pleural fluid are often associated with heart failure, infection secondary to a wire that has migrated from the rumen or infectious pleuritis, all of which carry a grave prognosis. 
    • Cattle also have a tendency to form fibrinous adhesions between the visceral and parietal pleura, which can in some circumstances make collection of fluid unrewarding, as often there is a labyrinth of small pockets of exudate, rather than one large reservoir.
Indications
  • Pleural fluid can arise from secondary causes of fluid accumulation - lymphosarcoma or other neoplasms, thoracic trauma, lung abscessation, infectious respiratory causes or migration of ingested wires from the reticulum resulting in infection and heart failure.
