Percutaneous lung biopsy is safe in healthy cattle, with minimal short-term effects. The Tru-Cut needle and Bard Biopty-System were more effective for obtaining biopsy specimens than the Autovac cannula.

Area of Science:

  • Veterinary Medicine
  • Surgical Procedures
  • Bovine Health

Background:

  • Lung biopsy is a diagnostic tool in veterinary medicine.
  • Assessing the safety and efficacy of different biopsy instruments in cattle is crucial for clinical application.

Purpose of the Study:

  • To evaluate the safety of percutaneous lung biopsy in healthy cows.
  • To compare the suitability of three biopsy instruments: Autovac biopsy cannula, Tru-Cut needle, and Bard Biopty-System.

Main Methods:

  • A prospective study involving 60 healthy cows undergoing bilateral lung biopsy.
  • Evaluation of short-term (1 day) and long-term (10 days) effects post-biopsy.
  • Comparison of specimen acquisition rates and postmortem findings for each instrument.

Main Results:

  • The procedure was safe, with transient collapse in 2 cows and no lasting adverse effects.
  • Minor pleural lesions (<5mm) were observed in 71% of biopsy sites.
  • High specimen acquisition rates were achieved with the Tru-Cut needle (96%) and Bard Biopty-System (97%), but not the Autovac cannula (9%).
  • Long-term examination revealed small scars without adhesions.

Conclusions:

  • Percutaneous lung biopsy is a safe and well-tolerated procedure in healthy cattle.
  • The Tru-Cut needle and Bard Biopty-System are recommended for obtaining lung biopsy specimens in cows due to their higher efficacy.
