Fluoroscopically Guided Percutaneous Disk Aspiration in 10 Dogs With Diskospondylitis

Fluoroscopically guided percutaneous fine-needle aspiration of the intervertebral disk space was performed in 10 dogs with diskospondylitis. Positive bacterial cultures were obtained from 9 of 12 aspirated disk spaces, 1 of 6 blood cultures, and 6 of 10 urine cultures. Positive disk cultures were obtained from 2 dogs with negative blood and urine cultures and from 2 additional dogs with low numbers of Staphylococcus in urine cultures. Adverse clinical sequelae of the procedure were not noted. Percutaneous fine-needle aspiration of the intervertebral disk space is an alternative technique to surgical biopsy to obtain positive bacterial cultures from dogs with diskospondylitis.
