Background: Brain trauma (BT) is the most common cause of death among children worldwide. In traumatic patient, the skull is the most common involved part. The importance of computed tomography (CT) scan in diagnosis of BT is well established. CT scan is actually a common option for evaluation of patients with cranial trauma. Considering the importance of CT scan in the diagnosis of brain lesions, the present study was aimed to survey the results of brain CT scan in traumatic patient attending the Ayatollah Taleghani Hospital (Kermanshah, Iran) during 2011.
Methods: In this descriptive and cross-sectional study brain CT scan results of 365 patients with head trauma attending the CT scan department of Taleghani Hospital (Kermanshah) during 2011 was evaluated. For data collection, pre-prepared tables containing demographic data, cerebral results, lesion and location of fractures were used. Finally the data were analyzed using descriptive statistics.
Results: The results show that of 907 patients, 557 were male and 350 female. In this study we performed CT scans on 365 traumatic patients, 326(89.31%) cases of 365 patients had normal brain CT scan and 39(10.69%) cases had positive finding including:
3 cases (7.69%) of brain contusion, 5 cases (12.82%) of epidural hematoma, 4 cases (10.26%) of subdural hematoma, 3 cases(7.69%) of subarachnoid hemorrhage, 2 cases (5.13%) of intracranial hemorrhage, 2 cases (5.13%) of intraventricel hemorrhage, and finally 20 cases (51.28%) of skull fracture.
Conclusion: Because of the high percentages of normal CT scan with no clinical indication in this study, it is necessary for clinical physicians to pay enough attention and rethink about performing a brain CT scan in a patient, particularly when they are not sure about the necessity of a performing CT scan. Furthermore, there is a need for further studies managing the current trend among physicians in which brain CT scan is going to be a routine application.
