Z. Kotwica et J. Brzezinski, ACUTE SUBDURAL-HEMATOMA IN ADULTS - AN ANALYSIS OF OUTCOME IN COMATOSE PATIENTS, Acta neurochirurgica, 121(3-4), 1993, pp. 95-99
The authors analysed a series of 200 adult patients admitted to the De
partment of Neurosurgery, Medical University of Lodz with a diagnosis
of acute subdural haematoma (ASDH). 63% of them were surgically treate
d within the first 4 hours after head injury, the others were operated
on 4 to 16 hours after trauma. All patients had GCS below 10 for the
whole time period from trauma to surgery. Younger patients 18-30 year
old had lower mortality -25%, while patients above 50 revealed 75% mor
tality. Analysis of operative timing and outcome, no benefit revealed
when surgery was performed within first 4 hours. However, the patients
operated on later than 4 hours after trauma had smaller midline shift
and less pronounced brain contusion. It must be taken into account th
at some patients who could benefit from early surgery-those with quick
ly developing haematomas and intracranial hypertension-had no chance t
o arrive and died in peripheral hospitals. Despite our results we advo
cate an urgent evacuation of haematoma, as early as possible after tra
uma. Significant correlation was found between midline shift, cerebral
contusion on CT scans and results of surgery. Patients with bigger mi
dline shift or presence of focal cerebral contusion revealed higher mo
rtality and worse outcome than patients with smaller shift and no cere
bral contusion visible on CT pictures.
