Impact of Verticalization on Intracranial Hemodynamics Assessed in Transcranial Doppler at the Acute Phase of Cerebral Infarction

The management of patients with ischemic stroke or transient ischemic attack is based on the preservation of a brain area by maintaining sufficient intracranial hemodynamics (IH) and with rapid recanalization. The impact of the patient's position (supine or seated position) on the IH in the event of narrowing or occlusion of an artery is poorly assessed but may be of particular importance. Variations in blood flow according to the positioning of the patient's body are measurable using a transcranial Doppler. The main objective is to verify whether intracerebral hemodynamic changes during early verticalization after ischemic stroke or transient ischemic attack are more frequent in patients with carotid stenosis or occlusion compared to those without stenosis or occlusion.
