BACKGROUND: We investigated Glasgow Coma Scale (GCS) scores, intracranial pressure (ICP) and cerebral perfusion pressure (CPP) changes, and long-term clinical outcomes in patients with severe traumatic brain injury (STBI) associated with bilateral non-reactive dilated pupils (BNDP) who underwent decompressive surgery (DS). METHODS: The study group consisted of 28 patients (11 females, 17 males) with BNDP from among 147 patients who underwent DS due to STBI in our department. RESULTS: The mean GCS score was 4.96±1.20 at admission and 4 preoperatively. Mean ICP in non-surviving patients after DS was higher (p<0.05). ICP decrease after DS was also higher in surviving patients than in non-surviving patients (p<0.05). The overall mortality rate was 61.02%. A GCS motor score >2 at admission was associated with lower mortality (p<0.05). Four of the surviving patients (14.28%) had a functional outcome (Glasgow Outcome Score: 4 and 5) at one year after hospital discharge. CONCLUSION: Outcome in patients with BNDP after STBI may not always be fatal or poor. Rapid DS may increase the chance of functional survival, especially in patients with admission GCS score of 6 or 7.
