About

The autonomic nervous system (ANS), regulating involuntary physiologic processes including heart rate and blood pressure, is affected by changes in the cerebral vessels like carotid artery stenosis, occlusion, carotid artery stent and endarterectomy.

Until now, no data concerning autonomic nervous system in patients with acute intracranial large artery occlusion and thrombectomy is available. Due to the known effect on ANS in case of pathologies of extracranial brain supplying arteries it is highly suspected that intracranial large artery occlusion and thrombectomy can affect the ANS as well.

The aim of this project is to determine autonomic parameters during and after thrombectomy in patients with large cerebral artery occlusion. The project is a prospective descriptive pilot study at the University Hospital Tulln. 20 patients will be assessed during and after thrombectomy up to three months post intervention. A combination of autonomic parameters, hemodynamic parameters and clinical outcome will be evaluated.
