Is it possible to recover from uncal herniation? Analysis of 71 head injured cases.

BACKGROUND

Uncal herniation (UH) caused by head trauma may become a fatal process if not treated rapidly.

METHODS

We analysed the factors affecting the outcome in 71 surgically treated patients who had intracranial haematoma diagnosed by computerized tomography (CT), between January 1987 and June 1994 with the symptoms of UH. Age, incident-treatment interval, Glasgow Coma Scale (GCS), type of the lesion and the presence of polytrauma were correlated with Glasgow Outcome Scales (GOS) using SPSS PC+ statistical software.

RESULTS

49.3% of our patients were referred because of a fall from a height and 46.5% because of a motor vehicle accident. 12.7% of the patients were polytraumatized. The mean GCS of the series was 5.662. The mean GCS of the patients expired and who were in good recovery state were 4.8 and 6.9 respectively. Age, presence of polytrauma, type of the lesion and time interval between the incident and the treatment was found to be statistically insignificant when correlated with GOS. The correlation value between the GCS values and GOS was found to be highly significant (p < 0.00001).

CONCLUSIONS

The findings showed that the degree of the herniation is the most important factor that affects the prognosis of the patients with UH. The reversibility of UH becomes more difficult if there are complications added during the grades of its progression but it may not be necessarily fatal and be reversible if appropriate interventions are rapidly performed.
