Epidurograms were performed on 47 dogs with clinical signs consistent with lumbosacral
compressive disease. Thirtyeight abnormal epidurograms were identified. Epidurograms
were considered abnormal when complete obstruction of cranial forward flow or dorsal
deviation over the lumbosacral junction were present. Dorsal laminectomies were performed
on 28 dogs with abnormal epidurographic findings. Surgical findings included: disc
herniation (17), connective tissue nerve root entrapment (5), fibrous connective tissue
mass (3), no abnormality (2), and instability (1). The strong correlation between
abnormal epidurographic signs and compressive lumbosacral lesions seen at surgery
(93%) suggests that epidurography can be a valuable aid in the diagnosis of lumbosacral
compressive lesions.
