Insights

Diabetes, coronary artery disease, stroke history, degree of stenosis, and early operation increase risk for cerebral hyperperfusion syndrome (CHS) after carotid revascularization. Robust collateral circulation is protective.

Area of Science:

  • Neurology
  • Vascular Surgery
  • Medical Research

Background:

  • Cerebral hyperperfusion syndrome (CHS) is a potential complication following carotid revascularization.
  • Identifying risk factors is crucial for preventing CHS and improving patient outcomes.

Purpose of the Study:

  • To identify and analyze the risk and protective factors associated with cerebral hyperperfusion syndrome (CHS) after carotid revascularization.

Main Methods:

  • A comprehensive meta-analysis was conducted.
  • Searched multiple databases including Cochrane Library, PubMed, Embase, Web of Science, CBM, CNKI, VIP, and Wanfang.
  • Included ten studies with a total of 158,624 participants.

Main Results:

  • Diabetes, coronary artery disease, history of stroke, degree of stenosis, and an operation time window of less than two weeks were identified as significant risk factors for CHS.
  • Robust collateral circulation was found to be a significant protective factor against CHS.
  • Factors such as male gender, hypertension, hyperlipidemia, alcohol consumption, smoking history, and intraoperative/post-operative hypertension did not show a significant association with CHS.

Conclusions:

  • This study elucidates key risk and protective factors for CHS post-carotid revascularization.
  • Findings can inform clinical practice for CHS prevention and management strategies.
