Abstract:
Practical relevance: Hematologic disorders are relatively common in cats, as inflammatory, immune-mediated and infectious diseases have the potential to impact erythroid, myeloid and thrombopoietic lines within the bone marrow. Clinical challenges: Clinicians often benefit from information obtained from bone marrow cytology and histopathology in diagnosing hematologic disorders in feline patients. However, these sampling procedures are ones that many veterinarians are intimidated by and thus not comfortably performing in clinical practice.
Audience:
This review, aimed at all veterinarians who treat cats, highlights the reasons a clinician may elect to sample bone marrow, and details the collection of bone marrow for both cytology and histopathology. Potential complications and limitations of each procedure are also reviewed. Evidence base: The collection of bone marrow for cytology and histopathology is not new to feline medicine and several research studies have investigated various sampling modalities in cats. This article offers a comprehensive review of the currently accepted best practices.
