Hemodynamic analysis of optimal branch selection for flow-diverting stents in middle cerebral artery bifurcation aneurysms: a pilot study

This study indicates that vessel DR could guide intraoperative decisions for FD placement in MCA bifurcations. Prioritizing smaller branches in certain anatomical profiles may enhance flow remodeling without increasing procedural risks. These findings suggest a hemodynamic basis for moving beyond traditional size-based approaches and could inform more precise stent selection in complex bifurcation interventions. Further validation through controlled trials is needed.
