title: Role of repeat CT scan head in initially inoperable cases of traumatic head injury.
abstract: The CT scan has become popular in cases of head injury. In this study 71 cases (M:48; 68.0% and F:23; 32.0%) with traumatic head injury admitted and initially managed conservatively at National Neurosurgical Referral Centre, Bir hospital starting from May 2005 to April 2006. The most common cause of injury was road accidents (43 cases) with motorcycle and bus injuries as the leading causes. Nausea and vomiting were the most common symptom in 41 (57.0%) cases, followed by headache in 31 (43.0%). Contusions were the most common radiological findings in 84.0% followed by extradural haematoma in 8.0% and pneumocephalus in 7.0%. Out of these the most common location for contusion was frontal (16 cases), followed by parietal (12 cases) and then bilateral contusions. The mean volume was 12 ml, 9 ml and 9 ml for frontal, parietal and temporal contusions, respectively. Repeat scan showed increase in volume of contusion in 31 cases (44.0%), no change in 28 cases (40.0%) and decrease in 12 cases (16.0%). The increase was mainly due to edema in 20 cases (64.0%) and due to actual increase in contusion in only 11 cases (35.0%). Only 5 (7.0%) cases needed operative intervention. It is concluded that routine use of repeat scan in mild to moderate head injury has no role unless there is clinical deterioration.
