title: Traumatic brain swelling and operative decompression: a prospective investigation.
abstract: Since 1978, decompressive craniotomy was performed according to a standardized protocol. Exclusion criteria were age greater than or equal to 40 years, deleterious primary brain damage, operable space occupying lesions, larger infarctions in CT scan or irreversible brain stem incarceration/ischaemic damage as shown by bulbar syndrome, loss in BAEP or oscillating flow in TCD. Indication was given by progressive intracranial hypertension not controllable by conservative methods, if ICP decompensation was correlated with clinical (GCS, extension spasms, mydriasis) and electrophysiological (EEG, SEP, CCT) deteriorations. 18 patients were decompressed by unilateral. 19 by bilateral craniotomy with large fronto-parieto-temporal bone flap and a dura enlargement by use of temporal muscle/fascia. 37 patients at an age of 18 +/- 7 (4-34) years were operated 5 h-10 d after trauma. Recovery was surprisingly good: only 5 died, 2 due to an ARDS; 3 remained vegetative, all others achieved full social rehabilitation or remained moderately disabled. The best predictor of a favourable outcome was an initial posttraumatic GCS greater than or equal to 7. These in younger patients with delayed posttraumatic decompensation before irreversible ischaemic damage occurs.
