Cerebral hyperperfusion syndrome (CHS) is increasingly recognized as an uncommon, but serious, complication subsequent to carotid artery stenting (CAS) and carotid endarterectomy (CEA). The onset of CHS generally occurs within two weeks of CEA and CAS, and a delay in the onset of CHS of over one week after CAS is quite rare. We describe a patient who developed CHS three weeks after CAS with status epilepticus.

Objective: To evaluate postoperative cerebral perfusion changes and their influencing factors in carotid endarterectomy (CEA) patients by integrating multimodal monitoring methods, including cerebral regional oxygen saturation (rSO), carotid ultrasound (CU), computed tomographic angiography (CTA), and computed tomographic perfusion imaging (CTP), with computational fluid dynamics (CFD) assessment.
Methods: We conducted a cohort study on patients with internal carotid artery (ICA) stenosis undergoing CEA at our institution. Pre- and postoperative assessments included CU, CTA, CTP, and rSO monitoring.

Introduction: It is largely accepted that migraine with aura (MA) is caused by cortical spreading depression (CSD) and that migraine without aura (MO) is not. This is mostly based on old studies of regional cerebral blood flow (rCBF) and studies of vascular responses. These studies are partly forgotten today and may, therefore, be worthwhile reviewing.

Objective: This study aimed to evaluate the utility of arterial spin labeling (ASL) in assessing cerebral blood flow (CBF) changes in amyotrophic lateral sclerosis (ALS), and its potential as a biomarker for early diagnosis.
Methods: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies that employed ASL to compare CBF between ALS patients and healthy controls were included.

Background: Hyperperfusion syndrome (HPS) is one of the most serious complications after carotid artery stenting (CAS). Arterial spin labeling (ASL) is a noninvasive method for assessing cerebral perfusion. This study aimed to evaluate the utility of ASL compared to that of SPECT in evaluating changes in intracranial blood flow during the perioperative period of CAS.
View Article and Find Full Text PDFCerebral hyperperfusion syndrome is a rare complication that can occur following carotid artery revascularization procedures in patients with chronic carotid artery stenosis. Cases of hyperperfusion syndrome resulting solely from intravenous tissue plasminogen activator administration, without a history of revascularization, are extremely rare. Only four of such cases have been reported with imaging evidence.
