Correlation of Clinical and Ct Scan Findings in Relation to Mortality in Deceased Victims Diagnosed with Extradural Hematoma

Extradural hematomas occur frequently as an intracranial finding in trauma to the head. The mortality and morbidity in head injury cases are assessed by factors like progressive deterioration of consciousness, patient age less than 80 years, Glasgow coma scale (GCS) of 5-11, lack of severe coagulopathy or presence of systemic disease; and CT findings like increased edema, compression on brain stem, shift effect hematoma location on non-dominant hemisphere. Very few attempts have been undertaken to study the dimensions and the effects of hematomas in the CT scans and to relate the findings in autopsy. This study was undertaken to analyze the epidemiological and pathological factors of extradural hematoma as well as to correlate the radiological findings in death cases to arrive at the factors influencing the mortality. Thickness and diameter of the hematoma and their relation to mass effect, ventricular shift and midline shift, and incidence of ventricular changes and herniation was studied.
