Computerized Tomographic Patterns and Correlation between Imaging Findings and Mechanism of Injury in Traumatic Head Injury patients, at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, 2016
Background: Head trauma is a major part of public health problem worldwide particularly in the young. Computerized tomography is the recommended first line imaging modality. The aim of this first phase thematic study was to document the CT pattern of head injuries on patients scanned at Tikur Anbessa Specialized Teaching Hospital and correlate with the mechanism of injury.
Materials and Methods: This cross-sectional prospective descriptive study included 348 patients with head injury imaged with CT at TASH, from March 2016 to August 2016. CT findings and clinical information were recorded and analyzed and correlated with the mechanism of injury.
Results: Males were more involved, 275(79%) with a male to female ratio of 3.8:1. The age range 20-39 years was the most frequently affected group, (44). RTA was the most frequent etiologic factor 117(55%), followed by assault 63(29.7%), and fall accident 31(14.6 %). Fall accident was the second frequent cause of injury in the pediatric age < 10 years while RTA was the leading one. Skull fracture was the commonest finding 172(49.4%), followed by brain contusion, 105(30.2 %) then epidural hematoma 56(16.1%). Mixed type of injuries were recorded in 158(45.4%) of cases.
Conclusion-This study has demonstrated that the most commonly affected groups in head injury are young males, the most frequent cause being RTA, also in the very young. High proportion of patients had CT findings. Appropriate clinical information is crucial for planning evaluation. The study reinforces the necessity of expanding CT service and concerted effort to reduced RTA.
