Key result
Inflammation drives intracranial aneurysm formation by unifying local hemodynamic stress, mechanical strain, and biochemical factors.
Why the study?
Inflammation is recognized as a key mediator of intracranial aneurysm formation, linking local flow alterations, wall mechanics, and biochemical factors, but its role requires further elucidation.
This review highlights the critical role of the inflammatory cascade and flow-induced endothelial dysfunction in the formation of intracranial aneurysms.
May inform aneurysm risk stratification; leaves open whether anti-inflammatory interventions alter formation or rupture risk.
The emergence of inflammation as a key mediator of aneurysmogenesis provides new opportunities to understand the processes underlying development of intracranial aneurysms (IA). Inflammation unifies the triptych influences of alterations in local flow, mechanical properties of the wall and biochemical mediators and opens new avenues for building robust predictive tools. This review discusses the impact of the inflammatory cascade during the formation of intracranial aneurysms, and its associated morphological, structural and mechanical changes especially in the setting of flow-induced endothelial dysfunction.

Turjman et al. (2014) conducted a review in Intracranial aneurysms. Inflammation and fluid dynamics was evaluated. Inflammation acts as a key mediator in the formation of intracranial aneurysms, unifying the effects of local flow alterations, wall mechanical properties, and biochemical mediators.
