Area of Science:

Neurology
Neurosurgery
Vascular Medicine

Background:

Neurointerventional surgery is standard for cerebral vessel stenosis/occlusion.
Endovascular thrombectomy is crucial for acute ischemic stroke.
Cerebral hyperperfusion syndrome (CHS) is a clinical event post-revascularization.

Purpose of the Study:

To review recent studies on CHS epidemiology, diagnosis, and management.
To identify uncertainties in CHS understanding and treatment.
To consider CHS in both acute and chronic cerebrovascular conditions.

Main Methods:

Literature review of recent studies on CHS.
Analysis of data predominantly from carotid angioplasty and stenting studies.
Discussion of diagnostic criteria and hemodynamic assessment using imaging.

Main Results:

CHS definition and diagnostic criteria are diverse.
Impaired cerebrovascular autoregulation is key, but mechanisms are unclear.
Clinical presentation and risk factors vary; diagnosis post-thrombectomy is complex, requiring consideration of reperfusion injury.

Conclusions:

Further research is needed to clarify CHS pathophysiology and standardize diagnosis.
Hemodynamic assessment aids pre-procedural patient selection.
Management includes intensive blood pressure control and staged angioplasty.
