Quantitative information - cell counts, bacterial culture - 25What are disadvantages of BA lavage?Expensive
Invasive
Limitations to cytology - 26Method of BA lavage?Advance broncoscope and wedge into smallest bronchus

Radiography - nodules
FNA - pneumothorax complication - 41Pathogenesis of Marie's disease in pulmonary neoplasia?Influences vagus nerve --> hind limb bone deposition --> painful swelling
- 42What are causes of pulmonary thromboembolism?Dirofilariasis
Heart disease
Surgery
Nephrotic syndrome - protein loss = hypercoagulable

IMHA
Neoplasia
Sepsis or DIC - 43How would you diagnose pulmonary TE?CS - acute severe dyspnoea, poor response to oxygen, loud/split S2
