Key result
An optimal stent implantation depth of 1-2 mm in a vertebral artery model minimizes the risk of thrombosis and plaque formation compared to excessive stent extension.
Why the study?
Stent implantation depth significantly influences vertebral and subclavian artery hemodynamics when treating vertebral artery stenosis.
Does optimal stent implantation depth (1-2 mm) improve hemodynamics and reduce thrombosis risk compared to excessive extension in a vertebral artery stenosis model?
Does optimal stent implantation depth (1-2 mm) improve hemodynamics and reduce thrombosis risk compared to excessive extension in a vertebral artery stenosis model?
Computational modeling suggests that limiting stent extension to 1-2 mm into the subclavian artery during vertebral artery stenosis treatment optimizes hemodynamics and minimizes thrombosis risk.
Optimal stent depth may reduce thrombosis risk in vertebral stenting; CFD results are hypothesis-generating and require clinical validation.
Stent implantation depth significantly influences the hemodynamics of the vertebral and subclavian arteries in treating vertebral artery stenosis. This study utilized computational fluid dynamics (CFD) to analyze key hemodynamic parameters in a vertebral artery model with a stent implanted at different depths. Results showed that excessive stent extension into the subclavian artery alters local blood flow, increasing the risk of thrombosis and plaque formation. An optimal implantation depth of 1-2 mm minimizes these risks. These findings provide a theoretical basis for optimizing stent placement, improving the efficacy and safety of interventional treatments for vertebral artery stenosis.
