Collateral circulation significantly improves prognosis in cerebral infarction: a meta-analysis

Area of Science:

• Neurology
• Cardiovascular Research
• Medical Imaging

Background:

• Cerebral infarction, or stroke, poses a significant health burden globally.
• The role of collateral circulation in stroke recovery remains an area of active investigation.

Purpose of the Study:

• To systematically evaluate the association between collateral circulation and prognosis in patients with cerebral infarction.
• To synthesize existing evidence through a meta-analysis.

Main Methods:

• Comprehensive literature search across multiple databases.
• Inclusion/exclusion criteria screening for relevant studies.
• Meta-analysis of extracted data using standard techniques.

Main Results:

• Analysis of 41 studies with 10,510 patients.
• Good collateral circulation significantly associated with favorable prognosis (OR = 1.67, 95% CI: 1.35-2.07).
• Consistent findings across subgroup analyses by region and sample size.

Conclusions:

• Collateral circulation is a critical determinant of prognosis in cerebral infarction.
• Enhancing collateral circulation presents a promising therapeutic strategy.
• Improved collateral function may lead to better clinical outcomes for stroke patients.
