Fate of Patients with Chronic Cerebrovascular Steno-occlusive Disease According to Change of Cerebral Perfusion, Cerebrovascular Reserved, and Incidence of Recurrent Ischemic Stroke.

Objective: The objective is to demonstrate change of cerebral perfusion and cerebrovascular reserve (CVR) in treating patients with cerebrovascular steno-occlusive disease stratified by change of cerebral perfusion and CVR.

Methods: Retrospective review patients with radiographic proven major cerebrovascular steno-occlusive disease whom underwent cerebral perfusion imaging with vasoactive stimuli stress test in Siriraj Hospital and Bangkok General Hospital during 2010-2018. Medical records were also reviewed.

Posterior C1-C2 fusion using C1 lateral mass and C2 pars screw with rod fixation: techniques and outcomes.

Objective: The atlantoaxial instability often requires posterior fixation surgery. Multiple techniques have been described for C1-C2 fixation. Transarticular atlantoaxial screw has been demonstrated to be effective for C1-C2 stabilization.

Degree of midline shift from CT scan predicted outcome in patients with head injuries.

Objective: To evaluate the relationship between the degree of midline shift by Computed Tomography (CT) finding and Glasglow Coma Score (GCS) as a predictive of clinical outcome in patients after head injury. METHOD AND METHOD: The present study was performed by retrospectively reviewing 216 consecutive cases of traumatic head injury admitted to the trauma center in Siriraj Hospital from 1999 until 2004. All patients were evaluated for level of consciousness by a neurosurgeon determining by GCS and underwent CT brain for evaluation of intracranial hemorrhage and midline shift.
