Abstract
- We analysed the results of 34 herniated lumbar disc patients who were treated with chemonucleolysis and took CT/discography from Jan. 1991 to Jun. 1992 at the Department of Neurosurgery, Presbytrian Medical Center, Chonju, Korea. The overall success rate of chemonucleolysis was 82.4%. The CT/discographic findings were divided according to whether fluorescing or not, and degeneration or not. The success rates in fluorescing and non-fluorescing group were 95.2% & 61.5%, respectively, and those in degeneration and non-degeneration group were 66.7% & 100%, respectively. So, the results showed that the outcome of chemonucleolysis was better when the herniated disc fragment demonstrated a large uptake of contrast material visible, or there was no annular appearance to describe degeneration on CT/discography.
