Role of Decompressive Surgery in the Management of Severe Head Injuries: Prognostic Factors and Patient Selection

Abstract

Decompressive surgery or craniectomy (DC) is a treatment option, which should be considered when the intracranial pressure (ICP) cannot be treated by conservative methods. The purpose of this study was to evaluate the benefits of decompressive craniectomy in patients with intractable posttraumatic intracranial hypertension and to evaluate the patient selection criteria for this management protocol. In this study, 100 patients with severe head injuries were involved. All patients were treated according to the European Brain Injury Consortium (EBIC) guidelines for severe head injuries and were assessed based on individual initial Glasgow Coma Scores (GCS), age, Glasgow Outcome Score (GOS), presence of systemic injury, changes in ICP, presence of mass lesion and the right timing for DC. All patients presented with a GCS of 8 or below. Based on their initial GCS, the patients were divided in two groups of 60 (group I with GCS 4-5) and 40 (group II with GCS 6-8) in each, respectively. Prognosis was evaluated according to the (GOS). After treatment with DC, 84 of the patients (84%) showed unfavorable and 16 (16%) showed favorable outcomes. In group I, 58 patients (96.6%) showed unfavorable and two (3.4%) showed favorable outcomes. In group II, 26 (65%) patients showed unfavorable and 14 (25%) showed favorable outcomes. The importance of initial GCS and age in patient outcomes were statistically significant. The presence of systemic injuries or mass lesions in outcomes were not statistically significant. Based on our findings, we conclude that patients with Glasgow Coma Scores of 6-8 are the best candidates for DC treatment.
