P07-8 - Arterial pressure management during carotid endarterectomy and neurological complications

Abstract

Carotid endarterectomy (CEA) is the surgical treatment for patients with high-grade carotid artery stenosis performed, either under general anesthesia (GA) or regional anesthesia (RA) to reduce the risk of stroke (1). Intraoperative neurological assessment, especially during carotid cross-clamping is mandatory and can be easily realized under RA in the awake patient (2). The management of mean arterial pressure (MAP) during clamping in order to reduce risk of ischemic stroke is debated. Routine practice is to keep MAP ≥ 20% above baseline to optimize collateral cerebral blood flow (1). The primary objective of this retrospective study was to evaluate the risk of neurological complications depending on different levels of MAP during carotid cross-clamping under RA.
