The practice of blind liver biopsy in the published recommended locations in horses carries significant potential risks. Ultrasound-assisted liver biopsy is recommended to reduce the risk of serious complications.

1. Introduction
Percutaneous liver biopsy is regarded as the best antemortem test for equine hepatopathy. Blind liver biopsies are still performed by practitioners, despite potential associated risks such as pneumothorax or hemorrhage. Direct or indirect ultrasound guidance allows for identification of the most appropriate site for liver biopsy. Our goal was to identify the frequency of sonographic identification of adequate liver tissue for biopsy in the published blind liver biopsy locations.
2. Materials and Methods
Serum liver parameters were evaluated in 36 middle-aged Quarter Horses to ensure that only horses with normal liver function were included in the study. The published blind liver biopsy region, just below a line drawn between the dorsal aspect of the tuber coxae and the point of the elbow in the right 11th to 14th intercostal spaces, was examined sonographically.
3. Results and Discussion
Only 39% of horses had liver visualized in the published blind liver biopsy region. None of the 36 horses had liver of adequate thickness for biopsy in the published region. When liver was not visible, lung was visualized instead in 55% of horses, bowel in 36% of horses, and both bowel and lung in 9% of horses. In many horses, liver tissue may be inadequate for biopsy in the published blind biopsy locations.
