Cerebral Blood Flow Study by Xenon-Enhanced Computed Tomography in Acute Cerebral Artery Occlusion

Creators Nakayama Hisato

The hemispheric cerebral blood flow (CBF) in 32 patients with acute cerebral artery occulusion was measured by means of xenon-enhanced compuetd tomography. Eighteen patients ware treated with endovascular thrombolysis by intra-arterial administation of thrombolytic agents and occuluded arteries were recanalized, while 14 patients were treated conservatively. The CBF and cerebrovascular reserve capacity in the well recovered or moderately desabled patients ware higher than those in patients of vegetative state or death. The mean CBF in the patients with both internal carotid artery and middle cerebral artery occlusion was sugnificantly lower than that in the patients with middle cerebral artery occlusion only. CBF study by means of xenon-enhanced computed tomography will be useful to determine candidates for local thrombolysis andto guess the prognoses of patients.
