Aim: Transcranial doppler is a cheap, non-invasive, well tolerated easy-to-use method. It is used for the assessment of main cerebral arterial stenosis and the collateral circulation, to evaluate the effect of extracranial occlusive disease on intracranial blood flow, detection of AVM and brain death diagnosing.In this study it is aimed to assess the posttraumatic cerebral hemodynamia in minor head injured patients.

Materials and Methods: 44 patients with minor head injury (Group 1) evaluated in the early 8 hours of posttraumatic period between July- 2003 and february-2004. The control group (Group 2) has composed of 24 healthy people. Bilateral blood flow velocities of middle cerebral arteries (MCA) had measured using transtemporal technique while internal carotid arteries were evaluated by submandibular examination. The groups compared according to age, sex, velocitiy parameters of MCA, mean velocity of extracranial ICA’s and VMCA/ VICA ratios.

Results: There was no statistically significant difference between the groups according to age and sex. The flow velocity, resistive indexes (RI) and pulsatility indexes were significantly higher in patients with minor head injury according to normal group. Opposite to this there was no significant difference in ICA velocities and VMCA/VICA ratios. 6 patients (13.6%) showed hyperemia findings although no vasospasm detected.

Cocnlusion: MCA velocities, pulsatility indexes (PI) and resistive indexes (RI) increases in patients with minor head injury. Our results supports the opinion reported in literature that vasospasm is not an expected finding in patients with minor head injury opposingly hyperemia can be seen at least in low persantages.
