شيوع و انواع ضايعات فضاگير مغز در بيماران ترومايي دچار اغما

Background and Objectives:Traumatic brain injury is one of the most common and important causes of mortality and morbidity. These lesions are divided into two types: primary, which are due to direct impact and secondary, which are due to traumatic complications like hypoxia, hypotension and traumatic space occupying lesions .The secondary type of brain injury is mostly preventable and treatable. Appropriate treatment of these lesions obviously improves the prognosis. The goal of this study was to determine the relationship between the type of traumatic lesion and the treatment results. Materials and Methods:230 patients with traumatic coma were studied during 40 months at imam and Shohada Hospitals in Tabriz. These patients were comatose when admitted and patients with other lesions such as abdominal or chest traumas as well as underlying diseases were excluded from this study. Results: The mean age of patients was 32.4 years. The patients had several types of lesions. Almost half of patients had been operated. Brain contusion was the most common finding and subdural hematoma had the poorest prognosis. Glascow coma scale and mydriasis were two factors affecting the surgical outcomes.Conclusion: Diagnostic and therapeutic procedures must be done as soon as possible. Patients, if indicated, should undergo the surgical operation before the deterioration of consciousness and occuring mydriasis.
