Collateral circulation after revascularization in moyamoya disease: influencing factors and underlying mechanisms

Category	Detail
Condition	Moyamoya Disease
Key Mechanisms	Genetic susceptibility, angiogenic growth factors, cellular components, structural regulators, clinical variables
Target Population	Patients with moyamoya disease undergoing cerebral revascularization
Care Setting	Cerebral revascularization surgery

Cerebral revascularization improves cerebral perfusion and may reduce stroke recurrence.
Postoperative collateral circulation formation varies significantly among individuals.
Factors influencing collateral circulation include genetic variants, angiogenic factors, and surgical modalities.
Direct revascularization may lead to better angiographic outcomes and lower stroke risk compared to indirect methods.
Poor collateral circulation is associated with higher incidence of recurrent ischemia and hemorrhage.

Diagnosis of moyamoya disease is based on clinical presentation and angiographic findings.

Risks include hyperperfusion syndrome and variability in collateral circulation formation.

Patients with moyamoya disease undergoing surgical intervention.

Pharmacological treatments have limited effects; surgical options are preferred.

Consider genetic testing for RNF213 variants in patients with moyamoya disease.
Evaluate surgical modality based on individual patient risk factors and expected outcomes.
Implement a multidisciplinary approach for managing moyamoya disease.
