A series of 1909 computed tomography(CT) scan performed for head injury mostly after traffic accident was retrospectively reviewed. 17 patients were found to have clearly definable traumatic intraventricular hemorrhage(TIVH). TIVH was associated with various brain lesions in most cases; Intracerebral lesions with contusional hemorrhage and subdural hematoma(Glasgow Coma Scale Score) coexisted in 6 and 5 instances. The outcome(Glasgow Outcome Scale) of this series was related with initial clinical findings, and 11 patiens survived. We have designed this study to assess the occurrence of TIVH in our series of head-injured patients in Korea, and to correlate these findngs with the clinical status, the presence of associated lesions, and their relation to final outcome of these patients, and conculsions are as follows: 1) The incidence of TIVH and its associated mortality is 0.9% and 35.3%, respectively, Most of them occurs below 5 th decade(70.6%) with male predominace(88.2%). 2) Mode of injury is mainly from traffic accident(94.1%), followed by fall down(5.9%). 3) The presence of concomitant lesions has a definite influence on poor outcome(P<0.02), whereas skull fracture or multiplicity of TIVH deos not. 4) Primary impact site to induce TIVH is primarily on frontal portion(58.9%). 5) With regard to brain stem injury in TIVH, the final outcome clearly depends on pathological demonstration on CT(P<0.005%), but not on location of hemorrhage(P<0.5%).
