Coagulation abnormalities and complications after percutaneous liver biopsy in horses.

Summary

# Editorial Summary: Coagulation abnormalities and complications after percutaneous liver biopsy in horses Percutaneous liver biopsy remains a valuable diagnostic tool for equine hepatic disease, yet haemorrhage represents its most significant clinical risk, particularly when liver dysfunction compromises coagulation capacity. Johns and Sweeney investigated the prevalence of coagulopathies in horses with liver disease and characterised both the nature and frequency of post-biopsy complications, addressing a notable gap in the equine literature where such associations had not been systematically documented. Their findings provide essential baseline data on which horses face heightened bleeding risk following the procedure and what interventions might be warranted pre-biopsy. For veterinarians, understanding the coagulation status of a patient with suspected liver disease becomes crucial when considering biopsy as a diagnostic pathway, potentially influencing decisions around timing, pre-procedure coagulation testing, and client communication regarding complication risks. Farriers and other equine professionals should be aware that horses recovering from recent liver biopsies may require modified work schedules and monitoring, particularly if coagulopathy was identified or bleeding complications occurred.
