[Hemodynamic monitoring in neuro-endovascular interventions].
We report on the feasibility of hemodynamic monitoring during occlusive neuro-endovascular procedures. The cerebrovascular reserve capacity as assessed by transcranial Doppler sonography was chosen as the hemodynamic parameter. A standardized stimulation of cerebral blood flow was achieved by a bolus injection of 100 mg acetazolamide (Diamox) i.v. Ten minutes after injection, the middle cerebral artery blood flow velocity of 54 arteries in 33 normal persons increased by 41% +/- 17.5 (mean +/- standard deviation). The lower threshold value was therefore set to 6% increase (mean minus 2 standard deviations). An application in a case of endovascular test- and permanent occlusion of an internal carotid artery is described.
